module / pump) with the conductive surface and/or with each other. Proceed according
to the grounding concept (Chap. 6.8).
Measure the equipotential bonding prior to commissioning the equipment.
Provide cyclic measurements of the equipotential bonding.

VDL (E3.1) 10/2020 Page 16/196
1.7.1.4 Accessibility to the disconnection from the power grid
To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
The chamber’s power plug is unprotected. The electrical connection must therefore be established outside
a zone.
1.7.1.5 Technical ventilation (extraction)
The operator shall provide active extraction (technical ventilation according to country-specific regulations
(TRBS 2152 Part 2 for Germany) before commissioning the chamber. Extraction must include the entire
installation area of the vacuum drying oven and a vacuum pump. Observe the area classification in the
surroundings of the chamber (chap. 3.5.3). Extraction must be active during the entire chamber operation.
Operation, loading and unloading of the loading material and removal of the filled condensate catchpot of
the pump must always take place under technical ventilation. If the technical ventilation fails, automatically
switch off power to the chamber.
This will prevent spreading of an explosive atmosphere to unprotected areas (see chap. 3.5).
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected ar-
eas and ignition due to electric sparking or hot surfaces.
Serious injury or death from burns and / or explosion pressure.
Provide active suction (technical ventilation according to country-specific regulations
(TRBS 2152 Part 2 for Germany) prior to commissioning the chamber.
Extraction must include the entire installation area of the vacuum drying oven.
Make sure that the chamber is automatically turned off if the technical ventilation fails.
1.7.2 Safety instructions on compressed air supply
Before starting / restarting the chamber, the electrical installation room, preheating chamber, and controller
housing (triangular instrument box) must be swept with compressed air with maximum overpressure for a
defined time (chap. 9.3).
Sweeping the area for electrical equipment, the preheating chamber and controller housing must take place
with an overpressure of at least 25 Pa (recommendation: >40 Pa) during the entire operation of the vacuum
drying oven. Also after termination or cancellation of the drying process, continued sweeping for at least 10
minutes is recommended.
An inlet pressure of 2 bar must be provided for compressed air sweeping. The compressed air supply line
provided by the operator must be equipped with a monitoring device which clearly indicates a drop and
increase in the inlet pressure outside the permissible tolerance of ± 0.2 bar.
DANGER
Explosion hazard by solvent-containing air penetrating the electrical area of the
oven or the preheating chamber.
Serious injury or death from burns and / or explosion pressure.
Make sure that sweeping the area for electrical equipment, preheating chamber, and
controller housing with compressed air for the defined time (chap. 9.3.2) at maximum
overpressure has been done before turning on the chamber.
Make sure that sweeping the area for electrical equipment, preheating chamber, and
controller housing with compressed air with an overpressure of at least 25 Pa (recom-
mendation: >40 Pa) takes place during the entire operation.
Ensure that the operator compressed air supply line is equipped with active monitoring
of the defined inlet pressure.

VDL (E3.1) 10/2020 Page 17/196
1.7.3 Safety instructions on vacuum supply
Prior to commissioning the chamber make sure that all relevant national and international regulations are
observed. Within the European Union, units that will be operated in potentially explosive areas have to meet
the requirements of ATEX Directive 2014/34/EU.
If combustible solvent is introduced into the drying chamber, the vacuum pump must be constructed in a
suitable explosion-proof manner.
Observe the safety instructions of the pump manufacturer.
1.7.3.1 Selection and location of a suitable pump
The mixtures extracted from the inner chamber must be carried away making sure that there is no danger
by ignition of these atmospheres. Sparking in the pump motor or the switching elements, electrostatic dis-
charges, as well as hot pump parts can ignite solvent vapors in the event of an error. To minimize this risk,
use an ATEX Directive 2014/34/EU compliant vacuum pump suitable for suction from Zone 0 or 1 and, if
appropriate, from the zone of its installation site.
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected
pump parts and ignition due to electric sparking on the pump motor or switching el-
ements, electrostatic discharges, or hot surfaces.
Serious injury or death from burns and / or explosion pressure.
Use only suitable, explosion-proof pumps. See chap. 6.5.1.
Operate the pump in a stationary position and secure it so it is immobile.
Make sure that the suction line to the vacuum connection (6) of the VDL is fixed and
conductive.
Ensure sufficient solvent condensation, e.g., in an exhaust waste vapor condenser, to
avoid that ignitable solvent concentrations are conducted from the pump. Otherwise,
the exhaust pipe after the pump must be fixed and conductive and suction must be
done in an explosion-proof area.
Ensure equipotential bonding between the pump, the VDL vacuum drying oven and, if
appropriate, the pump module using the connections of the grounding conductors ac-
cording to the grounding concept (Chap. 6.8).
Confirm that the vacuum pump is designed for a gas inlet temperature corresponding to
the used drying temperature, or take appropriate measures to cool down the extracted
vapor before it enters the vacuum pump.
Use ATEX compliant vacuum pumps providing an integral protective device for the
pump OR Install a current-dependent, delayed protective device for the pump (for the
triggering time of this protective device, see the manufacturer’s specifications). The pro-
tective and monitoring device must not be able to turn on independently again or be re-
leased.
Use ATEX compliant vacuum pumps providing an integral explosion proof switch OR
make sure that the switch gear box is either installed outside the hazardous area or that
it is explosion proof.
The ATEX compliant vacuum pump offered by BINDER provides an integral protective device
for the pump and an integral explosion proof switch.

VDL (E3.1) 10/2020 Page 18/196
1.7.3.2 Observing the permissible gas inlet temperature
Confirm that the vacuum pump / vacuum system is designed for a gas inlet temperature corresponding to
the used drying temperature, or take appropriate measures to cool down the extracted vapor before it enters
the vacuum pump / vacuum system. If the gas inlet temperature is too high and then becomes even warmer
by compression in the pump, the resulting temperature (of the gas-solvent mixture inside the pump) could
exceed the solvent’s temperature class and auto-ignition temperature. The ATEX compliant vacuum
pumps offered by BINDER are designed for a gas inlet temperature of 40 °C / 104 °F max. Do NOT
exceed this temperature.
DANGER
Fire and explosion hazard by exceeding the auto-ignition temperature of the solvent
due to excessive gas inlet temperature
Damage to the vacuum pump. Serious injury or death from burns and / or explosion
pressure.
∅ Do NOT exceed the maximum gas inlet temperature of the pump (ATEX compliant vac-
uum pumps from BINDER: 40 °C).
When operating with a higher set-point temperature take appropriate measures to cool
down the extracted vapor before it enters into to the vacuum pump.
1.7.3.3 Technical Ventilation (extraction)
When manipulating the vacuum pump (removing the filled condensate catchpot of the pump) or in the event
of an error (e.g. dropping or spilling the filled condensate catchpot) spreading of an explosive atmosphere
to unprotected parts of the pump or the vacuum drying oven would be possible.
The operator must provide active extraction (technical ventilation according to country-specific regulations
– TRBS 2152 Part 2 for Germany) prior to commissioning and manipulating the vacuum pump. Extraction
must include the entire installation area of the vacuum drying oven, the pump and, if appropriate, the pump
module. Handling the pump always takes place under technical ventilation.
This will prevent spreading of an explosive atmosphere to unprotected chamber parts other than the defined
area (see Chap. 3.5).
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected
parts of the pump or the vacuum drying oven and ignition due to electric sparking
or hot surfaces.
Serious injury or death from burns and / or explosion pressure.
Provide active suction (technical ventilation according to country-specific regulations
(TRBS 2152 Part 2 for Germany) prior to commissioning the vacuum pump.
Extraction must include the entire installation area of the vacuum drying oven, the pump
and, if appropriate, the pump module.
When using the pump module, connect an extraction system to the provided exhaust
port as described in the mounting instructions of the pump module (Art. no. 7001-0137).

VDL (E3.1) 10/2020 Page 19/196
1.7.4 Safety instructions on the charging material
The temperature class of the inner chamber according to IEC 60079-0 can be T1, T2, or T3. Only introduce
substances with an auto-ignition temperature that is higher than 200 °C / 392 °F. You can use a solvent
which would form an explosive mixture with air under normal conditions.
If the auto-ignition temperature of a solvent contained in the drying material is exceeded during the drying
process, there is an immediate risk of fire and explosion. This chamber is not suitable to dry substances
with an auto-ignition temperature below 200 °C / 392 °F. Substances falling under explosion group / gas
group IIC are not permitted (e.g. carbon disulfide, hydrogen).
Combustible dusts are generally not permitted, neither in the vicinity nor as a load.
DANGER
Explosion hazard due to unsuitable drying material.
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT introduce any substance with an auto-ignition temperaturebelow 200 °C / 392
°F into the chamber
∅ Do NOT introduce combustible dusts into the chamber.
∅ Do NOT introduce any substance which tends towards exothermal decomposition into
the chamber.
∅ Do NOT introduce any substance which comes under the explosive substance law into
the chamber.
∅ Do NOT introduce energy sources such as batteries or lithium-ion batteries into the
chamber.
∅ Do NOT introduce any substance which could lead to release of toxic gases into the
chamber.
Familiarize yourself with the physical and chemical properties of the charging material, as well as the con-
tained moisture constituent and its behavior with the addition of heat energy and changes in pressure. No
dangerous chemical reactions must occur during the drying process.
DANGER
Fire and explosion hazard caused by chemical reactions with the addition of heat
energy and changes in pressure.
Serious injury or death from burns and / or explosion pressure.
Make sure that no dangerous chemical reactions of the loading material can occur dur-
ing the drying process.
Familiarize yourself with any potential health risks caused by the charging material, the con-
tained moisture constituent or by reaction products that may arise during the drying process.
Take adequate measures to exclude such risks prior to putting the VDL vacuum drying oven
into operation.

VDL (E3.1) 10/2020 Page 20/196
1.7.5 Safety instructions on operating the vacuum drying oven
Note the following points before starting up the oven:
When loading the chamber and possibly at the moment of unloading, also in the context of
intended use, an explosive mixture may form in the working space. Define a safety area of
at least 1m from the chamber front and ensure active extraction (technical ventilation).
The walkable installation and operating surface of the chamber must be conductive. This
installation and operating surface must be connected to the vacuum drying oven according
to the grounding concept. Cyclic measurements of the equipotential bonding are required.
The operator must ensure an appropriate ventilation of the loading area in front of the
oven front prior to commissioning of the chamber.
Ensure that at no time any solvent vapors could enter in the area of the electrical installa-
tion room, preheating chamber, and controller housing (triangular instrument box).
Provide technical ventilation in the area of the vacuum pump stand, particularly in the areas
of the condensate catchpot (when emptying it) and the exhaust air of the vacuum pump.
The personal protective equipment (PPE) of the operating personnel must be ESD pro-
tected.
Only trained personnel with password authorization may work on the VDL vacuum drying
oven.
DANGER
Electrical hazard by water entering the chamber.
Deadly electric shock.
∅ The equipment must NOT become wet during operation, cleaning, or maintenance.
∅ Do NOT install the equipment in damp areas or in puddles.
Set up the equipment in a splash-proof manner.
DANGER

VDL (E3.1) 10/2020 Page 21/196
When operating the VDL vacuum drying oven with inert gas correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories (for Germany).
Do not start up the chamber without active technical ventilation .
During operation with inert gas the chamber is supplied with an oxygen displacing gas (e.g. N
2
). Inert gases
in high concentrations are hazardous to health. They are colorless and almost odorless and therefore prac-
tically imperceptible. Inhalation of inert gases can cause drowsiness up to respiratory arrest. When the O
2
content of the air decreases below 18%, there is risk of death from lack of oxygen. Any gas that might
escape has to be led out via good room ventilation or a suitable exhaust system.
DANGER
Suffocation hazard due to high concentration of inert gas.
Death by suffocation.
∅ Do NOT set up chambers in non-ventilated recesses.
Make sure that technical ventilation measures are active.
Respect the relevant regulations for handling inert gases.
When decommissioning the vacuum drying oven, shut off the inert gas supply.
If solvent-containing air penetrates the electrical area of the oven or the preheating chamber, explosions
may result.
DANGER
Explosion hazard by solvent-containing air penetrating the electrical area of the
oven or the preheating chamber.
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT take the air, which will be used to supply the chamber with compressed air,
from a potentially explosive atmosphere.
∅ Ensure that the operator compressed air supply line is equipped with active monitoring
of the defined inlet pressure.
The unit must not be operated without compressed air flushing at maximum overpressure and
running compressed air flushing with active monitoring of the defined inlet pressure.
Avoid the solvent accumulation in the optional pump module as this would cause the vacuum
module to become an occasionally or continuously / for long periods / frequently potentially ex-
plosive area (Zone 0 or 1). The VDL vacuum drying oven located on top of the module is im-
plemented in Device category 3 in regards to its surroundings.
DANGER
Explosion hazard due to operating the oven with material containing solvent that
may be able to form an explosive mixture with air.
Serious injury or death from burns and / or explosion pressure.
Follow the measures listed below for operation with solvent-containing materials that
can form an explosive mixture with air.

VDL (E3.1) 10/2020 Page 22/196
If the following precautions are not followed, the vapors resulting from heating of the solvent can ignite on
the hot walls of the inner chamber
Required measures for operation with solvent-containing materials that can form an ex-
plosive mixture with air:
• Sweep the area for electrical equipment, preheating chamber and controller housing
for a
defined time (chap. 9.3.2) prior to start-up with compressed air with maximum overpressure.
Subsequent sweeping of the area for electrical equipment, preheating chamber and control-
ler housing with an overpressure of at least 25 Pa (recommendation: >40 Pa) must take
place during the entire operating cycle
and must be monitored at the manometer on the
chamber front. In addition, monitoring of the defined inlet pressure (2 bar) of the compressed
air sweeping is required.
• Only after completing the defined sweeping time, put the chamber in operation.
• Take the auto-ignition temperature
from the safety specifications of the solvent. In the case
of solvent mixtures, use the auto-ignition temperature of the material with the lowest auto-
ignition temperature. Make sure that the auto-ignition temperature is above 200 °C.
• Enter the temperature set-point (drying temperature) on the controller.
• Set the safety controller (temperature limiter class 2). Recommended setting: safety control-
ler mode “Limit”, safety controller value approx. 5 °C above the set-point.
• During the drying process, use only those solvents for which the auto-ignition temperature
has been entered.
• Make sure that the technical ventilation is active. Make sure that the compressed air sweep-
ing is active and that the defined inlet pressure is monitored. Bring in the material to be dried.
• Start the drying process. The heating unit is only released when a pressure threshold of
100 mbar is reached.
• Make sure that sweeping the area for electrical equipment, preheating chamber and control-
ler housing with at least 25 Pa overpressure (see manometer display) takes place during the
entire operating cycle. Recommended value: >40 Pa.
• The duration of the drying process can be determined by means of the pressure display on
the controller. When the pressure drops to the set-point, the drying process is finished.
• Make sure that the technical ventilation is active. Make sure that the compressed air sweep-
ing is active and that the defined inlet pressure is monitored.
After termination of the drying
process, ventilate the vacuum drying oven with ambient air or inert gas.
Unload the loading
material and turn off the oven.
• Sweep the area for electrical equipment, the preheating chamber, and the controller housing
(triangular instrument box) at least 10 minutes with compressed air (recommended).
• Make sure that the technical ventilation is active when emptying the condensate catchpot of
the vacuum pump.
• Make sure that sweeping the area for electrical equipment, preheating chamber and control-
ler housing with at least 25 Pa overpressure (see manometer display) is active when empty-
ing the condensate catchpot of the vacuum pump. Recommended value: >40 Pa.
• Before starting a new drying process with a different solvent, check again the auto-ignition
temperature
at the safety specifications of the solvent. In the case of solvent mixtures, use
the auto-ignition temperature of the material with the lowest auto-ignition temperature. Make
sure that the auto-ignition temperature is above 200 °C.

1.9 Intended use
Following the instructions in this operating manual and conducting regular maintenance work
(chap. 25) are part of the intended use.
Any use of the chambers that does not comply with the requirements specified in this Operating
Manual shall be considered improper use.
Other applications than those described in this chapter are not approved.
Use
VDL vacuum drying ovens are suitable for drying and heat treatment of solid or nonflammable pulverized
charging material, as well as bulk material, using the supply of heat under vacuum.
During this process, the contained solvent may be able to form an explosive mixture with air under normal
conditions. Ignition of an explosive atmosphere is prevented in the VDL vacuum drying ovens by various
safety measures. The maximum drying temperature lies by a standard safety factor below the maximum
permitted auto-ignition temperature. The drying temperature must lie below the sublimation point of the
loading material.
The VDL vacuum drying ovens are approved for drying of materials with organic solvents. This may cause
unlimited amounts of solvents to appear temporarily. The chambers are equipped with an explosion-proof
inner chamber.
The VDL vacuum drying ovens are not intended for installation in a Zone 1 or 0. The chamber must not be
installed or operated in an occasionally or continuously / for long periods / frequently potentially explosive
area. Measures must be taken to prevent the spread of explosive atmospheres to unprotected areas.
The chamber plug (power plug) is unprotected because it must be disconnected in case of an emergency
to completely separate the chamber from the power supply. Therefore, the electrical connection must be
established outside a zone.
Temperature class
The temperature class of the inner chamber according to IEC 60079-0 is T3. It depends on the maximum
operation temperature inside the oven. The auto-ignition temperature is determined from the safety speci-
fications of the solvent used. In the case of solvent mixtures, the solvent with the lowest auto-ignition tem-
perature as this is critical.
According to IEC 60079-0 the VDL vacuum drying ovens are NOT suitable for the temperature classes T4,
T5 and T6. Insert only substances with an auto-ignition temperature that is higher than 200 °C / 392 °F.
The information listed on the on the type plate.for explosion protection is essential for classification.
For the Device category, refer to the area classification information on the site of installation in Chap. 3.5
.

VDL (E3.1) 10/2020 Page 26/196
Requirements for the chamber load
Insert only substances with an auto-ignition temperature that is higher than 200 °C / 392 °F into the VDL
vacuum drying ovens. The chambers are not suitable to dry substances with an auto-ignition temperature
below 200 °C / 392 °F. Substances falling under Gas group / Explosion group IIC are not permitted (e.g.
carbon disulfide, acetylene, hydrogen. Substances falling under groups II A and II B may be introduced.
The VDL vacuum drying ovens are NOT suitable for the heat treatment of substances, which tend towards
exothermal decomposition, or for materials that come under the legal definition of explosives. Such sub-
stances must not be introduced into the oven. Dangerous chemical reactions must not occur during the
drying process. Exothermal reactions must definitely be excluded. Familiarize yourself with the physical
and chemical properties of the loading material, as well as the contained moisture constituent and its be-
havior with the addition of heat energy and changes in pressure. Familiarize yourself with any potential
health risks caused by the loading material, the contained moisture constituent or by reaction products that
may arise during the temperature process. Take adequate measures to exclude such risks prior to putting
the chamber into operation.
VDL vacuum drying ovens are NOT suitable for use in conjunction with explosive dust atmospheres or
hybrid mixtures. Combustible dust are generally not permitted.
DANGER
Explosion or implosion hazard and danger of poisoning by introduction of unsuita-
ble loading material.
Serious injury or death from burns and / or explosion pressure or by poisoning.
∅ Do NOT introduce any substance with an auto-ignition temperature below 200 °C /
392 °F into the chamber.
∅ Do NOT introduce any combustible dust into the chamber.
∅ Do NOT introduce any substance, which tend to exothermic decomposition into the
chamber.
∅ Do NOT introduce any substance, which fall under the explosives law into the chamber
∅ Do NOT introduce energy sources such as batteries or lithium-ion batteries into the
chamber.
∅ Do NOT introduce any substance which could lead to release of toxic gases into the
chamber.
The loading material shall not contain any corrosive ingredients that may damage the ma-
chine components made of stainless steel and aluminum. Such ingredients include in particu-
lar acids and halides. Any corrosive damage caused by such ingredients is excluded from lia-
bility by BINDER GmbH.
Medical devices
The chambers are not classified as medical devices as defined by the Medical Device Directive 93/42/EEC.
Equipotential bonding
Safe grounding can avoid electrostatic ignition hazards. The most important protective measure is to con-
nect and ground all conductive parts. All conductive parts must have electrical potential. The grounding
plan (Chap. 6.8) must be implemented.
Avoid electrostatic charges. Clean the device only with a damp cloth. Avoid rubbing with non-
conductive materials.

VDL (E3.1) 10/2020 Page 27/196
Personnel Requirements
Only trained personnel with knowledge of explosion protection and knowledge of the Operating Manual can
set up and install the chamber, start it up, operate, clean, and take it out of operation. Service and repairs
call for further technical requirements (e.g. electrical know-how), as well as knowledge of the service man-
ual. Follow the requirements for PPE (ESD protection).
Installation site requirements
The chambers are designed for setting up inside a building (indoor use).
Provide active extraction (technical ventilation according to country-specific regulations – TRBS 2152 Part
2 for Germany) on the installation site. It must cover the entire installation area of the VDL and the vacuum
pump stand. Observe the area classification in the surroundings of the chamber (chap. 3.5.3). Suction must
be active during the entire operation of the chamber and when handling the condensate catchpot of the
pump. Suction must be conducted into an explosion-proof area.
Provide compressed air supply on the installation site. There must be at least 1.5 bar overpressure in the
supply line. The operator's compressed air supply line must be equipped with active monitoring of the min-
imum supply pressure (1.5 bar), which shall clearly indicate any drop in pressure below the minimum pres-
sure.
If the technical ventilation fails, automatically switch off power to the device.
VDL vacuum drying chambers are not intended for installation in a Zone 0 or 1. Measures must be taken
to prevent the spread of explosive atmospheres to unprotected areas. It must be possible to turn off the
device immediately in the event of a fault: Pull the power plug or operate e.g. a customer's explosion-
protected emergency stop switch.
The requirements described in the Operating Manual for installation site and ambient conditions (Chap. 5)
must be met.
In case of foreseeable use of the chamber there is no risk for the user through the integration of the chamber
into systems or by special environmental or operating conditions in the sense of EN 61010-1:2010. For this,
the intended use of the chamber and all its connections must be observed.

1.11 Residual Risks
The unavoidable design features of a chamber, as well as its proper field of application, can also pose risks
for the user, even during correct operation. These residual risks include hazards which, despite the inher-
ently safe design, existing technical protective equipment, safety precautions and supplementary protective
measures, cannot be ruled out.
Messages on the chamber and in the Operating Manual warn of residual risks. The consequences of these
residual risks and the measures required to prevent them are listed in the Operating Manual. Moreover, the
operator must take measures to minimize hazards from unavoidable residual risks. This includes, in partic-
ular the Operator measures described in chap. 2. Residual hazards are to be taken into account by the
operator in their risk assessment. This includes, in particular, issuing operating instructions.
The following list summarizes the hazards against which this Operating Manual and the Service Manual
warn, and specifies protective measures at the appropriate spots (list is not exhaustive):

VDL (E3.1) 10/2020 Page 32/196
2. Operator responsibility, documentation, and measures
This is NOT an exhaustive list of the required measures and documents!
Follow applicable national and international regulations.
The chamber is intended for commercial use. The operator must know, comply with, and implement the
relevant regulations on occupational safety. In particular, this includes the conditions of the Industrial Safety
Regulation 1999/92/EC (Title: Improvement of the Health Protection and Safety of Workers Who May Be
Endangered by Explosive Atmospheres). Known as ATEX 137, this directive was implemented in Germany
through the Industrial Safety Regulation (BetrSichV) and the Ordinance on Hazardous Substances
(GefStoffV).
2.1 Risk assessment / explosion protection document
First, a risk assessment is carried out to determine the hazards that are present where the chamber is
used due to the working conditions. When documenting the risk assessment, the operator must provide
specific evidence of the hazards posed by explosive mixtures in the explosion protection document.
When creating the explosion protection document, follow applicable national regulations (for Germany: In-
dustrial Safety Regulation (BetrSichV); Ordinance on Hazardous Substances (GefStoffV)).
In particular, the explosion protection document must indicate
• Determination and evaluation of explosion hazards
• Explosion protection plan
The explosion protection plan to be created by the operator represents the entirety of the technical and
organizational measures for explosion protection determined and specified on the basis of the risk as-
sessment. These measures should prevent the formation of hazardous explosive mixtures or to limit or
prevent their ignition. They should also minimize the spread of an explosion and its effects
The explosion protection document serves to document the results of the risk assessment in accordance
with § 6 Para. 9 GefStoffV (for Germany).
• Classification as explosion protection zones
• Explosion protection measures
• Cooperation with various companies
• Test findings on explosion protection and technical protection measures
2.2 Employee training and protocols
The operator must ensure that all employees have read and understood the Operating Manual.
Before employees use the vacuum drying oven and related work equipment for the first time, the operator
must provide them with sufficient and suitable information on the hazards presented and measures to be
taken in a form and language that is understandable.
This includes the information resulting from the risk assessment:
• Hazards when using the vacuum drying oven and related work equipment, in particular fire and explo-
sion hazards, functioning of protective devices
• Required protective measures and code of conduct
• Necessity of wearing personal protective equipment, which must be implemented ESD protected.

VDL (E3.1) 10/2020 Page 33/196
• Procedure for cleaning and repair work
• Measures for operational interruptions, accidents, and first aid for emergencies
The operator must clearly define the responsibilities for installation, operation, troubleshooting, mainte-
nance, and cleaning. It must be ensured that untrained personnel have no access to the chamber and
related work equipment and systems.
The operator must instruct employees with regard to their activity before they begin using the vacuum drying
oven and related work equipment. Following this, further instruction must be provided at regular intervals,
at least once per year. The date of each instruction and the names of the instructed persons must be
recorded in writing.
It is essential for safe and secure operation of the device that the user be familiar with the safety plan from
the manufacturer and the explosion protection plan from the operator.
Do not work on the chamber or in its surroundings, under any circumstances, after consuming alcohol,
drugs, and certain medications which may impair the ability to perceive, assess, and react.
2.3 Operating instructions
The measures to avoid hazards resulting from the risk assessment (Chap. 2.1) are to be specified as Op-
erating instructions. Before employees use the vacuum drying oven and related work equipment for the
first time, the operator must specify instructions for safe use in one or more operating instructions. These
must comply with regulatory requirements and be verified regularly to ensure that they are up to date.
When creating the operating instructions, follow applicable national regulations (for Germany: Industrial
Safety Regulation (BetrSichV); Ordinance on Hazardous Substances (GefStoffV)).
Keep these operating instructions with the chamber at all times in a place where they are
clearly visible. They must be comprehensible and written in the language of the employees.
2.4 Safety data sheets
A central component of the VDL safety plan is determining the correct auto-ignition temperature of the
solvent used. The corresponding maximum drying temperature (safety temperature) is then determined
according to the information panel “Temperature setting”. In the case of solvent mixtures, using the solvent
with the lowest auto-ignition temperature is essential. The data sheets for the solvents used must therefore
be available at all times. They can be maintained in writing or electronically. If they are stored electronically,
it must be ensured that all employees have access when needed. If an electronic medium is – temporarily –
not available, another source must be found or work must be postponed for this time. (DGUV 4.1)
2.5 Protective equipment
The operator must provide the operating personnel with the necessary protective equipment.
The personal protective equipment (PPE) of the operating personnel must be implemented ESD protected.
When using gloves make sure that they are conductive. The same applies for shoes and other elements
that can lead to electrostatic charges.

VDL (E3.1) 10/2020 Page 34/196
2.6 Standard Operating Procedures (SOPs)
The operator is responsible to determine the correct auto-ignition temperature of the solvent. To ensure
this, creating Standard Operating Procedures (SOPs) is recommended.
In particular, this should prevent the Residual Risks due to incorrect operation specified in Chap. 1.11
and the exceeding of the auto-ignition temperature of the solvent.
When creating Standard Operating Procedures, take into account the information and instructions in this
Operating Manual. The following are some examples of these risks and suggestions for measures to be
taken. These are to be created, adapted, and supplemented by the operator using the risks determined
and respective conditions at the installation site.
Risk Measures
Operation of the device by un-
trained users
• Ensure knowledge of the Operating Manual
• Use only ATEX-trained personnel
• Create operating instruction and standard operating procedures

2.1). The measures must be determined by the operator of the device based on the risks determined and
the respective conditions at the installation site.

VDL (E3.1) 10/2020 Page 35/196
2.7 Testing and maintenance
The operator must ensure that the chamber is always in a technically functional state.
Observe the maintenance intervals specified by the manufacturer. If there is above-average strain, the
intervals must be shortened accordingly.
The operator must regularly verify that the safety-related devices are functioning correctly.
Document tests with results and measures that were potentially initiated, as well as maintenance and re-
pairs, in a system book.
For testing before commissioning, see Chap. 7
For recurring tests and maintenance, see Chap. 7.5, 7.6, 25.
2.8 Operation log

3. Description of the equipment
Vacuum drying is used for special drying problems, for which conventional drying methods cannot offer a
solution due to physical limitations.
The VDL vacuum drying oven is approved for drying materials with organic solvents.
Ex classification
The chamber is equipped with an explosion proof inner chamber and additional measures for explosion
protection.
The Ex classification of the vacuum drying oven VDL (assembly) acc. to ATEX Directive 2014/34/EU is
II 2/3/- G IIB T3 Gb/Gc/- X
The description of explosion protection on the type plate determines the chamber’s classification.
Detailed information on the Ex classification of the assembly and the individual devices can be found in
chap. 1.8.
The maximum possible surface temperature of the chamber interior is 160 °C / 320 °F.
Installation
The VDL vacuum drying oven may be installed in areas in which explosive atmospheres may occur on a
rare and temporary basis. The entire chamber with the exception of the power plug is classified in category
3 in relation to the environment. The chamber plug (power plug) is unprotected, therefore the electrical
connection must be established outside a zone. With optional analog output: The plug connection of the
analog output is unprotected and must therefore be established outside a zone.
Temperature class
The temperature class of the inner chamber acc. to EN 60079-0 is T3. The temperature class of the entire
chamber equals the temperature class of the inner chamber.
Controller
The chambers are equipped with a multifunctional microprocessor display controller with 2-channel tech-
nology for temperature and pressure. Temperature is indicated accurate to one-tenth of a degree, the pres-
sure inside the chamber accurate to one 1 mbar. Pressure is measured by a firmly installed pressure sen-
sor.
The chamber is regularly equipped with the MB2 display program controller. This efficient program control-
ler is equipped with a multitude of operating functions, in addition to recorder and alarm functions. Program-
ming of test cycles is easily accomplished via the modern MB2 touch screen controller and is also possible
directly with a computer via Intranet in connection with the APT-COM™ 4 Multi Management Software
(option, chap. 24.1).
The chamber comes equipped with an Ethernetserial interfacefor computer communication and with a USB
interface. In addition, the BINDER APT-COM™ 4 Multi Management Software permits networking up to
100 chambers and connecting them to a PC for controlling and programming, as well as recording and
representing temperature and pressure data. For further options, see chap. 24.

VDL (E3.1) 10/2020 Page 37/196
Material
The inner chamber is made of especially corrosion resistant stainless steel V4A (German material no.
1.4404, US equivalent AISI 316L) micro-polished. The rack holder and all of the chamber's vacuum con-
nections and valves are made of especially corrosion resistant stainless steel V4A (German material no.
1.4571, US equivalent AISI 316Ti). The housing is RAL 7035 powder-coated. All corners and edges of the
housing are also completely coated. When operating the chamber at temperatures above 150 °C / 302 °F,
the impact of the oxygen in the air may cause discoloration of the metallic surfaces (yellowish-brown or
blue) by natural oxidation processes. These colorations are harmless and will in no way impair the function
or quality of the chamber.
The chambers are jacket-heated. The preheating chamber technique ensures a completely homogeneous
jacket temperature, ensuring uniform heat transfer into the inner chamber. The low-loss heat transfer to the
material uses the aluminum vacuum expansion racks (or optionally available in stainless steel). The elastic-
mounted safety glass window reliably compensates any overpressure or explosions that may occur. The
laminated safety glass pane ensures proven and effective splinter protection in the event of an implosion.
The chambers provide a universal connection for inert gas / ambient air, a compressed air connection for
sweeping the electrical installation area, the preheating chamber, and the controller housing, and a meas-
uring connection, e.g. serving to connect a measuring access port for the optional object temperature dis-
play.
All installable items, such as racks and rack holders, can be easily removed. The completely smooth inner
chamber with its rounded corners and internally welded seams is easy to clean.
The minimum working temperature of the vacuum drying oven is approx. 10 °C / 18 °F above room tem-
perature. The maximum temperature is 110 °C / 230 °F.
Vacuum pumps with a suction capacity of 1 m

3.1 Manufacturer's safety plan: Protective measures and equipment
The following measures were taken on the manufacturer’s side in order to prevent ignition and explosions.
• Ignition source monitored via safety temperature limiter (TL) class 1
Only solvents with an auto-ignition temperature above 200 ° C may be entered into the chamber.
There is a safety margin of 20% of the minimum permissible auto-ignition temperature of 200 °C, related
to the hottest point in the interior (where the heating is attached to the inner chamber). The maximum
surface temperature of the inner chamber is 160 °C. Therefore, when operated correctly, the hot sur-
faces are always below the auto-ignition temperature of permitted substances.
The safety temperature limiter (TL) serves to protect the vacuum drying oven, its environment and load-
ing material against exceeding the permitted temperature. It has a fixed switching threshold and pre-
vents exceeding the maximum surface temperature of the inner chamber of 160 °C in the event of a
fault. If this temperature is exceeded, the heater turns off. The TL protects the VDL vacuum drying oven,
its environment and the loading material against impermissible excess temperatures and prevents ex-
ceeding the maximum surface temperature in case of a fault.
The safety temperature limiter (TL) provides temperature monitoring through a thermal switch (bimetal
switch). If the permissible temperature is exceeded, the heating is switched off and an additional self-
holding circuit is activated, which is only reset when the power plug is removed and reconnected. This
prevents the heating from being automatically switched on again. When the TL is triggered, an alarm
message is displayed on the controller. An annual function check by the operator is recommended, for
this a controller test routine is provided (chap. 16.5).
The setpoint can only be set up to the maximum drying temperature of 110 °C / 230 °F.
Control technology ensures that there are no temperature overshoots when heating up.
The interior is hermetically sealed against the heating system. The heating elements are located pre-
heating chamber, which is swept with compressed air.

VDL (E3.1) 10/2020 Page 38/196
The outer surface of the preheating chamber (category 3) can reach a maximum of 195 °C.
Normal operation when used correctly: Even without taking into account the pressure control, which is
also effective in practice, there is no ignition source during the drying process. This also applies in the
event that the system is ventilated before the drying process finishes.
Fault: Incorrect loading with inadmissible solvent with a too low ignition temperature: Due to the vacuum,
there is no ignition source during the drying process. The drying process could safely be ended. In order
to cancel the drying process, it is the chamber must first have cooled to room temperature before ven-
tilation and opening (chap. 9.9.4).
• Taking into account the volume dependence of the auto-ignition temperature
The surface temperature is not to exceed 80% of the auto-ignition temperature of the gas or fluid, meas-
ured in °C.
Action: The safety margin of 20% of the auto-ignition temperature. is sufficiently large (EN1127-1:2019).
• Safety pressure monitoring with heater release by pressure switch
There is no explosive atmosphere in a vacuum. The heater is only released starting with a pressure
threshold of 100 mbar.
There is thus always a vacuum ≤ 100mbar during drying.
The protective measure of ignition source monitoring provides redundant safety during the drying pro-
cess: There are no hot surfaces at a pressure > 100 mbar, and, when used correctly, after the heater is
released the hot surfaces are always below the auto-ignition temperature of permitted materials.
• Sweeping the area for electrical equipment, the preheating chamber, and the controller housing
(triangle instrument box) with compressed air
The area for electrical equipment, the controller housing and the preheating chamber between the inner
and outer chamber where the heater is located, are protected against penetration of explosive atmos-
phere by a technical ventilation system.
Before each start-up, sweeping takes place with maximum overpressure. When the chamber is in oper-
ation, it is continuously swept with a minimum overpressure of 25 Pa (recommendation: >40 Pa). The
user must monitor the pressure on the manometer on the chamber front, especially when loading and
removing the loading material This reliably prevents explosive atmosphere to reach electrical or elec-
tronic parts of the VDL safety vacuum drying oven or at the heater (protection against solvent-containing
ambient air).
The compressed air supply line provided by the operator must be equipped with active monitoring of the
defined inlet pressure (2 bar).
• Heater shutdown in the event of component failure
In case of failure of the controller Pt100 temperature sensor or the heater Pt100 temperature sensor.
The heater is turned off. On the controller an alarm message is displayed.
• Measures for lacking / incorrect maintenance / adjustment / sensor drift
Proper maintenance requires that the controller sensor is correctly adjusted. The safety temperature
limiter (TL) provides sufficient safety against heating sensor drift.
Regular adjustment intervals for the controller sensor (annually) are specified (chap. 26.3).
• Prevention of electrostatic charges / grounding plan
All chamber components are at a common potential. The interior parts of the chamber are grounded.
The outer powder-coated housing plates have a layer thickness of 60 µm and are connected with the
earth potential via the protective conductor connection.
A detailed grounding plan for the VDL, the pump module, the pump and the installation and loading area
is provided, all components are prepared accordingly for grounding: Connections are available to ground
the device and accessories. Achieving equipotential bonding according to the grounding plan of the
manufacturer is mandatory, see operating manual chap. 6.8.

VDL (E3.1) 10/2020 Page 39/196
To create the connection between the vacuum drying oven and the pump, an antistatic PTFE hose is
used. All conductive parts have the same electrical potential. Also, the door handle is conductive.
Any clothing, shoes and gloves worn by the user shall be ESD protected.
When installed and operated as intended, there will be equipotential bonding for loading and unloading
and there is no risk of charges that are hazardous to operation.
• Extraction
Active extraction (technical ventilation) during operation of the VDL is mandatory.
The extraction has to be provided as technical ventilation according to country-specific regulations
(TRBS 2152 Part 2 for Germany). It must include the entire installation area of the vacuum drying oven
and pump. In normal operation, it affects in particular the loading area of the chamber to limit and reduce
any possible explosive atmosphere when loading the device.
Spreading of an explosive atmosphere to non-protected areas is prevented by the prescribed technical
ventilation.
Fault: If solvents or solvent vapors inadvertently reach areas of the installation location (e.g. if the ma-
terial to be loaded or the filled condensate catchpot of the pump fall down), the chamber must be turned
off immediately (pull the power plug or operate e.g., a customer's explosion-protected emergency stop
switch) in order to prevent explosive atmosphere from penetrating into non-protected areas. The tech-
nical ventilation at the installation site reduces the explosive atmosphere.
If, during a fault of the technical ventilation, material containing a solvent is located in the loading area
of the chamber, it must be removed immediately. If material containing a solvent is located inside the
chamber because it is being loaded at that moment, close the chamber door. The operator must ensure
that no explosive atmosphere remains in the area around the chamber when there is no active technical
ventilation. Ensure that the operator can manually turn off the chamber immediately (pull the power plug
or operate e.g., a customer's explosion-protected emergency stop switch) in order to prevent the cham-
ber from restarting automatically.
If, during a fault of the technical ventilation caused by a power failure, material containing a solvent is
located in the loading area of the chamber, the operator must ensure that after the power has been
restored, the technical ventilation and sweeping the electrical installation area, preheating chamber and
controller housing with maximum overpressure have been active for a defined time (chap. 9.3.2) before
turning on the chamber.
• Sealing
The area for electrical equipment is sealed so far that an overpressure can be built up. In combination
with sweeping with compressed air and the specified technical ventilation (extraction) provided by the
operator, the penetration of solvent vapors into the area for electrical equipment, preheating chamber,
and controller housing is prevented when loading the device as well as when unloading material that
has not completely dried.
• Authorization levels of the chamber controllers with password assignment
This makes it easier to restrict the use to trained users.
• Construction of the pump module and mandatory extraction, requirements for vacuum pumps
Various constructive features and measures to be taken by the operator prevent solvent vapors from
penetrating into the hot pump motor and into the electrical installation area, preheating chamber, and
controller housing (triangular instrument box) of the VDL in the event of incorrect operation, e.g. spilling
the content of the condensate catchpot of the pump when emptying it:
• Installation of the entire system under extraction (technical ventilation), this must run when emptying.
• Use of Ex pumps corresponding to the zoning is mandatory
• An extraction system provided by the customer must be connected to the port of the pump module.
This keeps the concentration in the pump module low
• The condensate collecting tray provided in the pump module prevents leakage

VDL (E3.1) 10/2020 Page 40/196
• The grounding plan / equipotential bonding prevents sparking
• The operator is responsible for the correct installation. He must ensure active extraction (technical
ventilation) when emptying the condensate catchpot of the pump (with or without a pump module)
• Spring-mounted safety glass panel
The VDL vacuum drying oven is equipped with a large-surface area safety valve. The inspection window,
consisting of ESG glass (toughened safety glass), is adjustable spring-mounted and serves as a safety
valve in the event of explosion. The laminated safety glass pane provides splinter-protection.
Further measures to prevent accidents
• Indications on the type plate
For Ex classification, temperature classes and electrical data, please refer to the operating manual
Chap. 1.6.
• Operating manual
An operating manual is available for each chamber.
• Temperature monitoring; safety, measurement, and control equipment
The chamber is equipped with a temperature display, which can be read from outside.
The safety, measuring, and control equipment is easily accessible.
• Non-ionizing radiation
Non-ionizing radiation is not intentionally produced, but released only for technical reasons by electrical
equipment (e.g. electric motors, power cables, solenoids). The machine has no permanent magnets. If
persons with active implants (e.g. pacemakers, defibrillators) keep a safe distance (distance of field
source to implant) of 30 cm, an influence of these implants can be excluded with high probability.
• Safety controller (temperature safety device class 2)
Temperature limitation via the controller by the safety controller serves to protect the vacuum drying
oven, its environment and loading material against impermissible temperature exceeding., that could
pose a fire risk. If the entered safety controller temperature is exceeded. The heater is turned off at all
poles until manual reset (class 2).
The safety controller must be checked according to its function at appropriate intervals. Test: Set the
safety controller value below the temperature set-point. The chamber must not reach the temperature
set-point, but must turn off the heater when the safety controller value is reached.
Recommended setting: safety controller mode “Limit”.
Visual and additionally activatable audible (buzzer) signals indicate temperature exceeding.
• Protection against touchable surfaces
Tested according to EN ISO 13732-1:2008.

3.5 Area classification, information for the zone classification
The operator is to classify the zones. The following areas are identified below:
• Unprotected areas. The spread of an explosive atmosphere to unprotected device parts must be reliably
prevented.
• Areas where, depending on the substances used, explosive atmospheres may occur on a rare and
temporary basis. The creation of a zone outside the defined areas must be reliably prevented.

3.5.2 Area classification in the surroundings of the chamber
The VDL vacuum drying oven, with the exception of the power plug and the plug connection of the optional
analog output, is classified in category 3 in relation to the environment. It may be installed in areas in which
explosive atmospheres may occur on a rare and temporary basis.
The chamber plug (power plug) is unprotected because it must be disconnected in case of an emergency
to completely separate the chamber from the power supply. Therefore, the electrical connection must be
established outside a zone. With optional analog output: The plug connection of the analog output is un-
protected and must therefore be established outside a zone.
Spreading of an explosive atmosphere, which may occur on a rare and temporary basis, to unprotected
areas must be reliably prevented by measures of the operator. In particular, this includes a sufficiently
dimensioned one technical ventilation according to country-specific regulations (TRBS 2152 Part 2 for Ger-
many) and compressed air sweeping).

4. Completeness of delivery, transportation, storage, and installa-
tion
4.1 Unpacking, and checking equipment and completeness of delivery
After unpacking, please check the chamber and its optional accessories, if any, based on the delivery
receipt for completeness and for transportation damage. Inform the carrier immediately if transportation
damage has occurred.
The final tests of the manufacturer may have caused traces of the shelves on the inner surfaces. This has
no impact on the function and performance of the chamber.
Please remove any transportation protection devices and adhesives in/on the chamber and on the doors
and remove the operating manuals and accessory equipment.
Due to different installation heights above sea level, a slight negative pressure in the inner chamber may
prevent the door from being opened. Therefore, after unpacking the chamber, remove the plug “Manual
ventilation” (7) for emergency ventilation from the tube to ensure pressure equalization. After this, thor-
oughly reinstall the plug.
CAUTION

may form. Before start-up, wait at least one hour until the chamber has attained ambient temperature and
is completely dry.
5. Location of installation and ambient conditions
5.1 General requirements for installation
Set up the vacuum drying oven on a flat, even and non-flammable surface, free from vibration, in a well-
ventilated, dry location and align it using a spirit level or laser. The site of installation must be capable of
supporting the chamber’s weight (see technical data, chap. 28.3). The chambers are designed for setting
up inside a building (indoor use). Provide active extraction (technical ventilation, chap. 5.2.2).
Minimum distances
• Distance between several chambers of the same size: 250 mm / 9.8 in
• Wall distances to rear: 100 mm / 3.9 in
• Lateral wall distances: 70 mm / 2.76 in
• Spacing above and behind the chamber: 100 mm / 3.9 in.

NOTICE
Danger by stacking.
Damage to the chambers.
∅ Do NOT place vacuum drying ovens on top of each other.
Permissible areas
The VDL vacuum drying oven may be installed in areas in which explosive atmospheres may occur on a
rare and temporary basis. The entire chamber with the exception of the power plug is classified in category
3 in relation to the environment. The chamber plug (power plug) is unprotected, therefore the electrical
connection must be established outside a zone. With optional analog output: The plug connection of the
analog output is unprotected and must therefore be established outside a zone.
VDL vacuum drying ovens are not intended for installation in a Zone 1 or 0. The chamber must not be
installed or operated in an occasionally or continuously / for long periods / frequently potentially explosive
area. Measures must be taken to prevent the spread of explosive atmospheres to unprotected areas.
Spreading of an explosive atmosphere to the unprotected areas must be reliably prevented. Observe the
information on zone classification (chap. 3.5).
Observe the instructions on extraction (technical ventilation, chap. 5.2.2). When installed as intended, there
is no Zone 1 or 0 in the vicinity of the chamber.
DANGER
Explosion hazard by penetration of an explosive atmosphere to unprotected areas.
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT operate the chamber in occasionally or continuously / for long periods / fre-
quently potentially explosive areas. It is not intended for installation in a zone 1 or 0.
Make sure that there are NO combustible dusts in the vicinity of the chamber
Make sure that air-solvent mixtures are NOT occasionally or continuously / for long pe-
riods / frequently in the vicinity of the chamber.
Strictly observe the relevant legal regulations about how to select an appropriate loca-
tion.
The operator is responsible for the correct installation of the pump or other equipment (zone classification).
Sufficient extraction (technical ventilation, chap. 5.2.2) also in the event of an error (e.g. damage / overfilling
the condensate catchpot of the pump, or spilling or dropping containers or material to be loaded with sol-
vents) must be provided.
The operator is responsible to use suitable pumps for pumping from zone 0 or 1.
Follow country-specific regulations for explosion protection.
If you ordered the optional pump module with chemical membrane pump, the vacuum pump will be deliv-
ered in a separate box and must be fitted into the module and connected at the place of installation (chap.
6.5.3).
Electrical connection
To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
It is also possible to use a customer’s explosion-protected emergency stop switch or a comparable power
disconnector.
The chamber plug (power plug) is unprotected because it must be disconnected in case of an emergency
to completely separate the chamber from the power supply. therefore, the electrical connection must be
established outside a zone.

VDL (E3.1) 10/2020 Page 51/196
DANGER
Explosion hazard due to sparking when disconnecting an improper electrical con-
nection.
Serious injury or death from burns and / or explosion pressure.
Make sure that the electrical connection is located outside a zone t.
Connect the plug outside the installation area of the VDL and the pump. Take into ac-
count the information on zone classification (chap. 3.5.2)
For the user there is no risk of temporary overvoltages in the sense of EN 61010-1:2010.
5.2 Ventilation and extraction (technical ventilation)
5.2.1 Ventilation for heat removal in normal operation
Install the vacuum drying oven in a well-ventilated place.
NOTICE
Danger of overheating due to lack of ventilation.
Damage to the chamber.
Do NOT set up chambers in non-ventilated recesses.
Ensure sufficient ventilation for dispersal of the heat.
Observe the prescribed minimum distances when installing the chamber (chap. 5.1)
5.2.2 Technical ventilation during chamber operation and when emptying the conden-
sate catchpot of the pump
Provide active extraction at the location of installation. The extraction shall be provided as technical venti-
lation according to country-specific regulations (TRBS 2152 Part 2 for Germany). It must include the entire
installation area of the chamber.
In normal operation, it affects in particular the loading area of the chamber for the spatial limitation and
reduction of any possible explosive atmosphere when loading the chamber. Also in the event of a fault (e.g.
if the material to be loaded or the filled condensate catchpot of the pump falls down), it causes spatial
limitation and reduction of any possible explosive atmosphere.
Extraction must be active during the entire operation of the chamber and when handling the condensate
catchpot of the pump. Extraction must lead into an explosion-proof area.
The operator must ensure active extraction before starting up the chamber. Extraction must be provided
during the entire operation of the chamber as well as when handling the condensate catchpot of the pump.
This ensures that solvent vapors never reach unprotected areas or accumulate in an impermissible manner.
If the technical ventilation fails, the power to the vacuum drying oven must be switched off. It must be
ensured that the device can be switched off by the operator using an explosion-protected device: Pull out
the power plug or operate e.g., a customer’s explosion-protected emergency stop switch.
5.2.3 Air supply (breaking the vacuum) during operation with inert gas
When operating the VDL safety vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories, issued by the
employers’ liability insurance association (for Germany).

VDL (E3.1) 10/2020 Page 52/196
5.3 Equipotential bonding
The accessible installation and operating surface of the chamber must be electrically conductive. The ac-
cessible installation and operating surface of the chamber must be electrically conductive. This installation
and operating surface must be connected to the vacuum drying oven and other equipment (e.g. Pump
module, vacuum pump) according to the grounding concept. Provide cyclic measurements.
For the grounding concept see chap. 6.8.
When inserting or loading objects into the loading area , note that there may be a potential equalization.
The personal protective equipment (PPE) of the operating personnel must be implemented ESD protected.
5.4 Ambient conditions
• Permissible ambient temperature during operation: +18 °C / 64 °F to +32 °C / 90 °F.
The ambient temperature should not be substantially higher than the indicated ambient tem-
perature of +22 °C +/- 3 °C / 71.6 °F +/-5.4 °F to which the specified technical data relate. De-
viations from the indicated data are possible for other ambient conditions.
• Permissible ambient humidity: 70 % r.h. max., non-condensing.
• Installation height: max. 2000 m / 6562 ft above sea level.
The maximum permissible ambient temperature of the vacuum pumps delivered by BINDER is 40 °C / 104
°F.
5.5 Compressed air supply for sweeping the area for electrical equipment, the
preheating chamber, and the controller housing
Before commissioning the chamber, connect the vacuum drying oven to the compressed air supply (chap.
6.3).
The compressed air supply line provided by the operator must be equipped with active monitoring of the
defined inlet pressure (2 bar), which clearly indicates a drop and increase in the inlet pressure outside the
permissible tolerance of ± 0.2 bar.
5.6 Fire extinguisher
During operation a fire extinguisher must be available.
5.7 Lightning protection device
The building in which the vacuum drying oven is installed must have a lightning protection system. All
internal connections in the operator's building must contain lightning protection in accordance with EN/IEC
62305-3.
Lightning protection measures must be taken in order to prevent melting and spraying effects. The opera-
tor’s zone classification shall be used to plan lightning protection measures. The lightning discharge paths
must be designed so that heat or ignitable / spray sparks cannot become the ignition source for an explosive
atmosphere.

VDL (E3.1) 10/2020 Page 53/196
6. Installation and connections
The chambers may only be installed, connected, and commissioned by specialist personnel. Specialist
personnel must have knowledge of the types of ignition protection and regulations and ordinances for
equipment used in hazardous areas (Ex areas).
Verify whether the Ex classification (Ex classification label on the type plate) is suitable for the application.
6.1 Vacuum expansion racks and rack holders
Vacuum expansion racks and rack holders can easily be removed from the chamber. This offers the
advantage of an inner chamber with smooth walls, which is easy to clean.
Inserting or loosening an expansion rack and inserting or removing the rack holders may only be
done in the absence of solvents and under extraction (technical ventilation).
The rack holders can only be removed from the chamber after removing the expansion racks.
Rack holder installation: Align the rack holders to the cams in the bottom of the inner chamber and insert
them.
Prior to insertion check the expansion racks and rack holders for corrosion . If corrosion is detected, the
affected element must not be used.
DANGER
Explosion hazard due to creation of mechanical sparks in an explosive atmosphere.
Serious injury or death from burns and / or explosion pressure.
Insert or remove the expansion racks and rack holders only in the absence of solvent.
Insert or remove the expansion racks and rack holders only with active extraction
(technical ventilation).
Prior to inserting the expansion racks and rack holders, check them for corrosion.
∅ Do NOT use corroded expansion racks and rack holders.
The vacuum expansion racks made of aluminum (also option-
ally available in stainless steel) allow low-loss heat transfer to
the material. The strong tension causes the racks to fit tightly
against the interior wall and their large-surface contact area
ensures rapid and effective heat transfer.
The removable rack holders allow for easy positioning.
You can remove the expansion racks for easy cleaning. Do
not remove them too often in order to prevent wear.
Figure 10: Operating the expansion racks
• Pushing the locking lever: The expansion rack is released and can be removed.
• Pulling the locking lever: The expansion rack is pressed against the inner chamber walls.
Remove or insert the vacuum expansion racks only when the chamber is empty and has
cooled down. NO explosive atmosphere must be present. Active extraction (technical ventila-
tion) is mandatory.

VDL (E3.1) 10/2020 Page 54/196
Following each new tightening of an expansion rack, check that the lateral parts of the rack fit
closely over their whole surface to the inner chamber wall. This is necessary in order to en-
sure the specified temperature exactitude.
NOTICE
Risk of invalid calibration due to modified heat transmission when changing be-
tween aluminum and stainless-steel racks.
Undefined heating behavior.
∅ Do NOT change between aluminum and stainless-steel racks
∅ Use the supplied expansion racks only.

6.3 Connecting compressed air supply for sweeping the area for electrical
equipment, the preheating chamber, and the controller housing
The compressed air flows through the area for electrical equipment, the preheating chamber, and the con-
troller housing, which prevents a possible concentration of a solvent-containing atmosphere in the presence
of live electrical components and the hot heater surface.
Use only dry compressed air.
In order to avoid that any oil coming from the compressed-air piping
enters the vacuum drying oven, the compressor of the compressed
air system must be equipped with an oil separator, or the com-
pressed air system must be constructed oil-free.
Connection:
Before commissioning, the pressure regulator on the chamber rear
must be connected to a compressed air line (compressed air net-
work).
Connection: Plug connector for DL quick coupling NW5
An inlet pressure of 2 bar must be provided for the compressed air
sweeping. The compressed air supply line provided by the operator
must be equipped with monitoring which clearly indicates a drop
and increase in the inlet pressure outside the permissible tolerance
of ± 0.2 bar.

pump module (Art. no. 7001-0137).
Before commissioning, measure the equipotential bonding after first setting up the VDL
and implementing all described measures for establishing the equipotential bonding
Provide cyclic measurements of the equipotential bonding.

VDL (E3.1) 10/2020 Page 59/196
6.4.3 Connection of an extraction system at the pump module
Avoid the solvent accumulation in the pump module as this would cause the pump module to
become an occasionally or continuously / for long periods / frequently potentially explosive
area (Zone 0 or 1). The VDL vacuum drying oven located on top of the module is constructed
in device category 3 in regards to its surroundings.
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected
chamber parts and ignition due to electric sparking or hot surfaces
Serious injury or death from burns and / or explosion pressure.
Provide active extraction (technical ventilation according to country-specific regulations
– TRBS 2152 Part 2 for Germany) prior to commissioning the chamber.
Extraction must include the entire installation area of the vacuum drying oven and pump
module.
Connect an extraction system to the provided port on the rear of the pump module.
6.5 Vacuum connection
Connect the vacuum drying oven to a vacuum pumpor to a domestic vacuum system. For this purpose, the
vacuum connection (6) with small flange DN16 must be connected to the back of the chamber at the top
with the vacuum pump or domestic vacuum system via a vacuum suction hose or a fixed vacuum pipe.
(6)
Figure 15: Position of the Vacuum connection (6) on the chamber rear (example size 56)
When using a vacuum suction hose BINDER recommends the connection kit for the VP4 pump from
BINDER (chap. 6.5.5). The optional pump module (chap.) provides an appropriate hose port on the rear.
6.5.1 Instructions for using vacuum pumps
Vacuum pumps with a suction capacity of 1-30 m³/h are suitable for the VDL vacuum drying
oven.
For use of vacuum pumps in the European Union, note the following points:
• Units that will be operated in potentially explosive areas have to meet the requirements of ATEX Di-
rective 2014/34/EU. Observe the safety instructions in chap. 1.7.

VDL (E3.1) 10/2020 Page 60/196
• If combustible solvent will be introduced into the inner chamber, the vacuum pump must be constructed
in a suitable explosion-proof manner. The mixtures extracted from the drying chamber must be carried
away making sure that there is no danger by ignition of these atmospheres.
Follow the safety instructions of the pump manufacturer.
In the event of an error, sparking in the pump motor or the switching elements, electrostatic discharges, as
well as hot pump parts can ignite solvent vapors. Minimize this risk by using an ATEX Directive 2014/34/EU
compliant vacuum pump suitable for suction from Zone 0 or 1 and, if appropriate, from the zone of its
installation site.
DANGER
Explosion hazard caused by emerging solvent vapors, which can ignite due to
sparking in the pump motor or the switching elements, electrostatic discharges and
hot pump parts.
Serious injury or death from burns and / or explosion pressure.
Use only suitable, explosion-proof pumps
Operate the pump in a stationary position and secure it so it is immobile.
Make sure that the suction line to the vacuum connection (6) is installed fix and conduc-
tive.
Avoid that the exhaust pipe conducts ignitable solvent concentrations by sufficient sol-
vent condensation e.g., in an exhaust waste vapor condenser
Make sure that the exhaust pipe is installed fix and conductive in case it may still con-
duct ignitable solvent concentrations.
Ensure equipotential bonding between the pump housing and the housing of the VDL
vacuum drying oven via the connected equipment grounding conductors of both units.
When using ATEX Directive 2014/34/EU non-compliant pumps:
Provide a current-dependent, delayed protective device for the pump (for the triggering
time of this protective device, see the manufacturer’s specifications). The protective and
monitoring device must not be able to independently turn on again or be released.
Install the switch gear box outside the hazardous area or provide it with explosion pro-
tection.
The ATEX Directive 2014/34/EU compliant pumps offered by BINDER provide an integral
protective device and an integral explosion proof switch.
Make sure that the vacuum source is designed for a gas inlet temperature corresponding to
the used drying temperature, or take appropriate measures to cool down the extracted vapor
before it enters into the vacuum source.
Observe the permissible gas inlet temperature of the vacuum pump in use. Do NOT exceed this
temperature. If the gas inlet temperature is too high and then becomes even warmer by compression in the
pump, the resulting temperature (of the gas-solvent mixture inside the pump) could exceed the solvent’s
temperature class and auto-ignition temperature .

VDL (E3.1) 10/2020 Page 61/196
DANGER
Fire and explosion hazard by exceeding the auto-ignition temperature of the solvent
with a too high gas inlet temperature.
Damage to the vacuum pump. Serious injury or death from burns and / or explosion
pressure.
Do NOT exceed the maximum gas inlet temperature of the pump. Adjust the tempera-
ture set-point accordingly.
With a higher set-point temperature, take appropriate measures to cool down the ex-
tracted vapor before it enters into the vacuum pump.
Extracted vapors can have a health damaging and/or corrosive effect on the chamber and pump.
CAUTION
Health hazard due to release of extracted vapors.
Corrosion of oven and pump. Damage to health.
Conduct the extracted vapors e.g., into a fume extractor facility. Connect a suitable
hose to the vacuum pump outlet that may be located in the pump module.
To avoid condensation inside the chamber and in the suction system, select an appropriate vacuum source
to ensure its sufficient performance in relation to the released amount of steam. Coordinate drying temper-
ature, suction performance of the vacuum source and the amount of loading material.
6.5.2 Vacuum pump VP4 (option)
. The VP4 chemical membrane pump is located in a separate transport packaging. It is delivered as com-
plete pump stand with a separator and an exhaust waste vapor condenser.

Defining the zone of the installation site of the vacuum pump (Directive 1999/92/EC)
If the pump module is defined as Zone 1, the operating chamber of the vacuum pump must be swept with
inert gas. A flow of at least 1 liter per minute (without pressure) is needed. For Zone 2 or without any zone
sweeping with inert gas is not required. In addition to sweeping with inert gas, in case of condensing media,
you can connect a gas ballast in order to avoid condensation.
The ATEX Directive 2014/34/EU compliant vacuum pump offered by BINDER is designed for a gas
inlet temperature of 40 °C / 104 °F max. Do NOT exceed this temperature. If the gas inlet temperature is
too high and then becomes even warmer by compression in the pump, the resulting temperature (of the
gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and auto-ignition tem-
perature.
DANGER
Fire and explosion hazard due to exceeding the solvent’s auto-ignition temperature
by exceeding the gas inlet temperature.
Damage to the vacuum pump. Serious injury or death from burns and / or explosion
pressure.
Do NOT exceed the set-point temperature 40 °C / 104 °F.
With a set-point temperature above 40 °C / 104 °F, take appropriate measures to cool
down the sucked-in gas before its entry to the vacuum pump.
The maximum permissible ambient temperature of the vacuum pumps supplied by BINDER is 40 °C /
104 °F.
6.5.3 Installation of the vacuum pump VP4 in the pump module (option)
Avoid the solvent accumulation in the pump module as this would cause the pump module to
become an occasionally or continuously / for long periods / frequently potentially explosive
area (Zone 0 or 1). The VDL vacuum drying oven located on top of the module is constructed
in device category 3 in regards to its surroundings.
Installation of the supplied vacuum pump
• The vacuum drying oven is mounted onto the pump module as described in the mounting instructions
Art. No. 7001-0137.
• The suction line to the pump module is installed as described in the mounting instructions Art. No. 7001-
0137. Connect the vacuum connection (6) (small flange DN 16) on the back of the chamber to a vacuum
suction lead. When using a vacuum tube BINDER recommends the BINDER connection kit for VP4
(chap. 6.5.5). The optional pump module has a corresponding hose outlet on its rear.
• When the pump is removed from the original packaging, place it in the pump module.
• Connect the grounding elements as described in the mounting instructions Art. no. 7001-0137.
• Connect the pre-installed suction line to the vacuum pump inlet at the suction-side small flange connec-
tion located at the top of the condensate catchpot).
• Connect a conduit that is suitable for removing the extracted vapors from the pump module, onto the
pressure-side connection of the vacuum pump (hose olive on the top-back of the emission condenser).
• Guide the end of the conduit into an exhaust air system, which is explosion-proof constructed in consid-
eration of any possible residual solvent contents. The operator must check if an explosive atmosphere
may be present at the pump exit or at the exhaust waste vapor condenser. For this purpose, use a
calculation of the solvent’s partial pressure at the set-up coolant temperature of the exhaust waste vapor
condenser and compare it to the explosion limits of the pumped solvent. The exhaust solvent concen-
tration should be minimized by selecting the most appropriate condensation temperature for the solvent
at the refrigeration plant that can be connected to the exhaust waste vapor condenser.

VDL (E3.1) 10/2020 Page 63/196
The pumped-out gases at the pump exit or the exhaust waste vapor condenser must be removed in a
controlled manner and according to applicable security regulations. If there is any possibility that an
explosive mixture could still exist, the exhaust must be removed through antistatic conduits and disposed
of according to the valid regulations of explosion protection.
• Establish the electrical connection at the pump’s connector box. This must be carried out according to
the original user manual of the pump manufacturer and to EN 60079-0, observing the zone that has
been defined by the operator for the installation site of the pump. Equipotential bonding between the
pump housing and the housing of the vacuum drying oven must be assured by the connected equipment
grounding conductors of both units.
Inappropriate execution of the pump connection can lead to the risk of explosion.
DANGER
Danger of ignition and explosion by inappropriate pump connection .
Serious injury or death from burns and / or explosion pressure.
It is obligatory to follow the instructions of the pump manufacturer regarding correct
connection and commissioning.
Observe the safety advice as in chap. 1.7.
Extracted vapors or the occasionally used inert gas can endanger health and / or have a corrosive effect
on the oven and pump.
WARNING
Danger of damage to health by release of extracted vapors.
Corrosion on the chamber and the pump. Damage to health.
Remove the extracted vapors and/or inert gas via a suitable conduit from the pump
module into e.g., a fume extractor facility.
Directly connect the conduit to the corresponding pump outlets.
You can connect a laboratory cooling system to the emission condenser of the vacuum pump
VP4.
To operate the chemical membrane pumps VP4 (MZ2C EX) please refer to the enclosed
pump manufacturer's operating manual.
Confirm that the vacuum source is designed for a gas inlet temperature corresponding to the
used drying temperature, or take appropriate measures to cool down the extracted vapor be-
fore its entry into the vacuum source.
The ATEX Directive 2014/34/EU compliant vacuum pump offered by BINDER is designed for a gas
inlet temperature of 40 °C / 104 °F max. Do NOT exceed this temperature. If the gas inlet temperature is
too high and then becomes even warmer by compression in the pump, the resulting temperature (of the
gas-solvent mixture inside the pump) could exceed the solvent’s temperature class and auto-ignition tem-
perature .
The maximum permissible ambient temperature of the vacuum pump supplied by BINDER is 40 °C / 104 °F.

VDL (E3.1) 10/2020 Page 64/196
6.5.4 Note on the use of a flame arrester
A flame arrester is not mandatory for VDL applications (TRBS 2152-4:2012). A pump designed for Zone 1
is equipped with a temperature sensor on the bearing which, in the event of a fault, causes the pump to
shut down immediately.
In general: In case of a risk of ignition before or after the vacuum pump, the operator must provide suitable
flame arresters in accordance with EN 12874. The suitability (chemical resistance, sufficient flow and safety
against clogging) must be ensured before commissioning.
6.5.5 ATEX connection kit for vacuum pump VP4 (option)
Connection kit for VP4 (Art. no. 8012-0621) consists of:
• Straining ring DN10/16 (3 pc.)

• Union nut M14 (2 pc.)
• Elbow DN 10/10
For mounting the VDL connection kit for VP4, please refer to the mounting instructions Art.
no. 7001-0152 supplied with the connection kit.
6.6 Connecting inert gas supply
When operating the VDL vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories, issued by the
employers’ liability insurance association (for Germany
When operating with inert gas, the chamber is supplied with an oxygen displacing gas, e.g., N
2
. Inert gases
in high concentrations are hazardous to health. They are colorless and almost odorless and therefore prac-
tically imperceptible. Inhalation of inert gases can cause drowsiness up to respiratory arrest. When the O
2
content of the air decreases below 18%, there is risk of death from lack of oxygen. Any gas that might
escape has to be led out via good room ventilation or a suitable exhaust system.
DANGER
Risk of suffocation by inert gas in a high concentration.
Death by suffocation.
∅ Do NOT set up chambers in non-ventilated recesses.
Ensure that technical ventilation measures are activated.
Respect the relevant regulations for handling inert gases.
When decommissioning the vacuum drying oven, turn off the inert gas supply.
Connect the inert gas supply to the inert gas connection (adapter with hose olive diameter 8 mm / 0.31 in)
via a pressure reducer. Screw the enclosed adapter with hose olive on the thread (4) at the chamber rear.
Set the pressure reducer to a pressure slightly above ambient pressure. Ensure that the pressure reducer
will certainly open. Do not alter this setting in order to avoid perturbation inside the oven and release of big
quantities of inert gas after flooding the VDL.

VDL (E3.1) 10/2020 Page 65/196

6.8 Achieving equipotential bonding / Grounding concept
For systems in potentially explosive areas, equipotential bonding acc. to IEC 60079-14 is required. All elec-
trically conductive parts must be connected to the equipotential bonding system. Connections to the equi-
potential bonding system must be secured against automatic loosening.
Grounding, i.e. achieving equipotential bonding is required as solvent vapors may be present during loading
and / or unloading. Also when removing the filled condensate catchpot from the pump solvents may acci-
dentally be spilled. Therefore, the accessible surface of the installation and loading area must be conduc-
tive, there must be technical ventilation, and all equipment (VDL / pump module / vacuum pumpmust be
connected to the conductive surface or to each other according to the grounding concept. The personal
protective equipment (PPE) of the operating personnel must be implemented ESD protected.

How to achieve equipotential bonding when installing the VDL with a pump module is de-
scribed in detail in the mounting instructions for the pump module (Art. No. 7001-0137) sup-
plied with the pump module.
Achieving equipotential bonding on the VDL
Equipotential bonding must always be made via external grounding connections, so that no potential can
be introduced in the event of a short circuit. Following the installation of the VDL and having imple-
mented all the measures described to achieve equipotential bonding, we recommend performing a
protective conductor measurement before commissioning.
The VDL provides a threaded bushing for grounding on the bottom
left of the rear panel. In state of delivery the screw together with the
washer and spring washer is screwed on the threaded bushing.
Unscrew the screw.
Threaded bushing after unscrewing
Washer, spring washer, screw
Put the washer, the ring cable lug of the grounding cable and the
spring washer in this order onto the screw.
OR
Put the spring washer, the ring cable lug of the grounding cable, and
the washer directly onto the housing (recommended because this
creates minimum resistance)
Screw on the screw into threaded bushing.

DANGER
Explosion hazard by electric sparking due to missing or improperly implemented
equipotential bonding.
Serious injury or death from burns and / or explosion pressure.
Connect all elements in the installation and loading area (VDL / pump module / pump)
with the conductive surface and/or with each other. Proceed according to the grounding
plan in chap. 6.8.
For installation of the pump module proceed acc. to the mounting instructions of the
pump module (Art. no. 7001-0137).
Make sure that the personal protective equipment (PPE) of the operating personnel is
implemented ESD protected. This applies also to gloves.
Before commissioning, measure the equipotential bonding after first setting up the VDL
and implementing all described measures for establishing the equipotential bonding.
Provide cyclic measurements of the equipotential bonding.
Always wear ESD-protected safety clothing when operating the chamber.

• The domestic socket must also provide a protective conductor. Make sure that the connection of the
protective conductor of the domestic installations to the chamber’s protective conductor meets the latest
technology. The protective conductors of the socket and plug must be compatible!
DANGER
Electrical hazard due to lack of a protective conductor.
Deadly electric shock.
Make sure that the power plug and power socket match and that the protective
electrical conductors of the chamber and domestic installation are securely con-
nected.
• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified
data located on the chamber’s type plate (left chamber side, bottom right-hand, see chap. 1.6).

To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
A customer's emergency stop switch or a comparable power disconnector can also be used.
The chamber plug (power plug) is unprotected because it must be disconnected in case of an emergency
to completely separate the chamber from the power supply. Therefore, the electrical connection must be
established outside a zone.
DANGER
Explosion hazard due to sparking when disconnecting an electrical connection.
Serious injury or death from burns and / or explosion pressure.
Make sure that the electrical connection is located outside a zone.
Connect the plug outside the installation area of the VDL and the pump. Take into ac-
count the information on zone classification (chap. 3.5.2)

7. Explosion safety tests before commissioning
This chapter provides instructions for the user to ensure the safety of the system and to meet applicable
regulations. Proper operation is only ensured after the test has been carried out and any necessary
measures implemented.
Follow the provisions on testing explosion protection according to country-specific regulations (for Germany
in particular TRBS 1201 Part 1; this substantiates the requirements of the Industrial Safety Regulation
(BetrSichV) 2015) within the scope of its application.
7.1 Scope of the functional test
The test represents the entirety of all work equipment relevant to explosion protection. This includes the
vacuum drying oven with all safety, control, and regulation devices, related work equipment such as pumps
or other vacuum systems, pump module, extraction devices, and ventilation systems, gas warning devices,
inerting devices including connection elements as well as the installation area with effective devices for
equipotential bonding and any other building components that may be relevant to explosion protection (non-
exhaustive list).
• Before commissioning and after changes requiring review, perform a comprehensive inspection of the
system in its entirety.
• Systems must be checked in their entirety at least every 6 years.
• Tests can also be carried out by an approved monitoring body or by personnel qualified for testing.
Observe relevant regulations for the qualification requirement.
• Devices, protective systems, safety, control and regulating devices according to Directive 2014/34/EU,
connection devices, and interactions with other parts of the system must continue to be checked at least
every three years. Tests of ventilation systems, gas warning and inerting devices must be performed at
least once per year in the future.
• It may be possible to skip recurring tests, e.g. of devices, protective systems, etc., as well as ventilation
systems, gas warning and inerting devices, if a maintenance plan is provided. The full inspection of the
entire system remains unaffected.
7.2 Explosion protection plan
The explosion protection plan to be created by the operator represents the entirety of the technical and
organizational measures for explosion protection determined and specified on the basis of the risk assess-
ment. In accordance with ATEX Operational Directive 1999/92/EC, these measures serve
• to prevent the formation of or to limit explosive atmospheres or to limit hazardous explosive mixtures
• to avoid the combustion of explosive atmospheres
• to limit the spread of an explosion and to minimize its effects on personnel in order to ensure the health
and safety of employees
The explosion protection document serves to document the results of the risk assessment in accordance
with § 6 Para. 9 GefStoffV (for Germany).
The explosion protection document serves to document the results of the risk assessment in accordance
with § 6 Para. 9 GefStoffV (for Germany).

VDL (E3.1) 10/2020 Page 71/196
7.3 Objective of testing
Determine the suitability and functionality of safety-related measures. When testing the explosion safety of
the system, evaluate the explosion protection plan and compare the target state derived from it with the
actual state of the system (according to available test records):
• Assess the completeness and plausibility of safety-related documents (such as the explosion protection
document, installation plans, zone plans, safety-related figures)
• Determine whether the system has been set up in accordance with national regulation (GefStoffV for
Germany) and is safe for use with regard to explosion protection
• Technical measures are suitable and functional for explosion protection,
• Technical organizational measures necessary for explosion protection are suitable
• The deadline for the next recurring test was correctly set in accordance with national regulations (in
accordance with § 3 Para. 6 BetrSichV for Germany).
Performing tests
The tests can be divided into the verification of the documentation and a technical examination.
7.4 Testing before initial commissioning
Proceed according to country-specific regulations (for Germany in particular: TRBS 1201 Part
1; BetrSichV).
Before the initial commissioning of the Ex system, perform the explosion safety test. It serves to determine
the explosion safety of the system, including the work equipment and the working environment.
The test represents a comprehensive consideration of the explosion safety of the Ex system with regard to
the protection of employees and other persons in the hazard area, including all functional units relevant to
explosion protection and their interactions. The test of explosion safety is based on the explosion protection
plan from the employer in accordance with the specifications in the explosion protection document and its
implementation in the Ex system. Equivalent test results according to other legal regulations can be con-
sidered. It is also permissible to refer to tests that have already been carried out.
7.4.1 Scope of the test
7.4.1.1 Testing the plausibility of the explosion protection plan and measures
Verification of the traceability and plausibility of the explosion protection plan given in the explosion protec-
tion document and the measures derived from this in consideration of underlying constraints.
The test does not apply to systems for which this test has already been carried out in the course of a permit
or approval process.
7.4.1.2 Verifying the implementation of measures
Verification of the measures described in the explosion protection document with regard to their implemen-
tation includes a holistic examination of the technical and organizational measures in accordance with the
specifications of the explosion protection document. Typical test aspects (examples):

VDL (E3.1) 10/2020 Page 72/196
• Suitability and functionality of technical ventilation systems, gas warning systems, inerting devices, de-
vices, protective systems, or control or regulating devices in the sense of Directive 2014/34/EU as well
as explosive devices in the sense of TRGS 725
• Suitability and implementation of the measures determined on the basis of the risk assessment
• Suitability, functionality, and installation of work equipment and related connection devices that are not
devices, protective systems, or safety, control, or regulating devices in the sense of Directive
2014/34/EU, but are relevant for explosion protection
• Suitability of other work equipment, such as ladders, containers, tools, for use in hazardous areas
• Suitability and functionality of other equipment and building components related to explosion protection
(e.g. lightning protection systems, conductivity of floors and linings)
• Suitability of the personal protective equipment (PPE (e.g., the electrostatic discharge capacity of work
shoes or gloves )
• The existence and legibility of the labels for potentially explosive areas in which measures to avoid
ignition sources are required
• The existence and suitability of the organizational measures required for explosion protection
• The implementation of measures relevant to explosion protection from official requirements
• Certificates proving the correct installation of system parts, provided that their correct installation cannot
or only partially be ascertained during the technical inspection, e.g. flame-arresting fittings or limit
switches
7.4.1.3 Checking the deadlines for the recurring tests
When doing so, assess whether the system can be operated safely until the next specified recurring test.
7.4.1.4 Verifying the maintenance plan
When doing so, assess whether the maintenance plan is suitable for maintaining the safety of the Ex system
until the next recurring test. The maintenance plan can also be used to test the technical protective
measures for explosion protection of the explosive system. It can also be part of an integrated management
system.
• Definition of responsibilities for the maintenance plan, definition of maintenance and inspection con-
tent, e.g. when creating work plans, processing the maintenance and inspection content, e.g. in the form
of work plans, the assessment of deviations from the target state, and any necessary repairs.
• Determination of maintenance and inspection measures and deadlines for devices, protective systems,
safety, control and regulating devices as well as their connections and interactions, technical ventilation
systems, gas warning devices and inerting devices and MSR devices for explosion protection
• Comprehensible description of the required maintenance measures and deadlines e.g. in the form of
work plans, work equipment of comparable design can be summarized.
• Implementation of the maintenance plan: Implementation of maintenance and inspection in accordance
with the defined maintenance plan, notification of completion of the implementation of maintenance and
inspection, documentation of identified repair needs and implementation of the repairs. Necessary
maintenance measures must be carried out immediately. Maintenance work must be carried out by
qualified specialist personnel who have sufficient experience in the maintenance of Ex systems based
on the maintenance plan. The maintenance plan and the implementation of maintenance measures
must be clearly documented.

VDL (E3.1) 10/2020 Page 73/196
7.4.2 Tests of technical ventilation systems, gas warning devices, inerting devices, de-
vices, protective systems or safety, control or regulating devices, and other tech-
nical devices for explosion protection
Test content that has been checked and documented as part of conformity assessment procedures do not
need to be checked again. Verify the plausibility and completeness of documents.
The following points must generally be verified:
• Technical ventilation systems, gas warning devices, inerting devices with regard to their suitability, their
functionality, their interconnections, their installation conditions, their proper condition, and their instal-
lation / assembly
• Devices, protective systems, or safety, control, or regulating devices within the meaning of Directive
2014/34/EU on explosion protection with regard to their proper condition, their suitability, their intercon-
nections, their installation conditions, and their installation / assembly
• Safety, control, or regulating devices with relevance for explosion protection, which can also be located
outside the potentially explosive atmospheres, to determine whether ventilation systems, gas warning
devices, inerting devices ensure the proper exclusion of ignition sources and functionality.
• Calibration of the Pt 100 controller sensor and, if required, subsequent adjustment is to be made before
commissioning the chamber as well as part of the annual maintenance. The procedure is described in
the Service manual (customer version).
• Ex devices in the sense of TRGS 725, whether they ensure the necessary functional reliability of the
measures.
• Connection elements and other technical devices (such as lightning protection, requirements for floors)
with regard to their condition, their interconnections, and their installation / assembly for explosion safety
(e.g. type of installation, insulation resistance of electrical cables and lines)
• Take into account the significant interactions of devices, protective systems, safety, control, or regulating
devices and their connecting elements – with each other and with other system parts. This includes, for
example, testing the equipotential bonding, the involvement of pipes in equipotential bonding, overvolt-
age protection, and lightning protection, alignment of units (e.g. pump-coupling-motor).
7.5 Inspection after changes requiring review
There is a need for a change requiring review if the explosive safety of the explosive system is affected by
the change. Changes requiring review are evaluated in accordance with applicable national regulations (for
Germany in particular: TRBS 1123). Checks after a change requiring review may be limited to the changes
made. Verify whether the system in the potentially explosive area has been changed in accordance with
this regulation and is working properly. See the requirements in Chap. 7.4.
7.6 Recurring tests for the explosive safety of the system
Objective of testing: The recurring tests serve to maintain the explosive safety of the Ex system. Among
other things, the actual state of the system is compared with the target state (according to the explosion
protection document and available test records).

8.6 Performance during and after power failures
During a power failure, all controller functions are shut down.
If there is a vacuum and ventilation is required during the duration of the power failure, this is possible via
the emergency ventilation (chap. 9.9.3).
After the power returns, all functions return to the same status the chamber had before power failure.
All settings and set point values remain in the memory during power failure.
• If the Standby mode had been activated prior to the power failure, the chamber remains off after the
power returns. To operate it you must sign in with a higher authorization level and deactivate the standby
mode.
• If the Standby mode had been deactivated prior to the power failure, operation continues after the power
returns with previously entered parameters. If the pressure reaches or falls below the required pressure
threshold of 100 mbar, the heater turns on depending on the setpoint.
After the power returns, the controller continues to function in the original operating mode it was in previ-
ously before the power failure occurred:
• Performance after power failure in Fixed value operation mode
All functions return to the same status the chamber had before power failure. The set-points are imme-
diately resumed.
• Performance after power failure during Timer operation
The set-points which had been active at the moment of program start are resumed. Program run con-
tinues.

VDL (E3.1) 10/2020 Page 83/196
• Performance after power failure during Time program operation
The program is resumed at the point where the interruption occurred with the latest set-points reached
during the program run.
• Performance after power failure during Week program operation
The week program continues with the values corresponding to the current time.
Power failure and power return are noted in the Event list (chap. 13.5).
If during power failure an alarm has occurred (e.g., tolerance range, safety controller), confirm the alarm.
See chap. 16.3.
9. Start up and performing the drying process
With regard to operating the vacuum drying oven VDL and to the installation location, please observe the
relevant national regulations (for Germany in particular: DGUV guidelines 213-850 on safe working in la-
boratories, issued by the employers’ liability insurance association; Industrial Safety Regulation (Be-
trSichV); Ordinance on Hazardous Substances (GefStoffV); Technical Regulations on Industrial Safety and
Health (TRBS 1201 Part 1).
Note: Warming chambers may release odors in the first few days after commissioning. This is not a quality
defect. To reduce odors quickly we recommend heating up the chamber to its nominal temperature for one
day and in a well-ventilated location.
Do not start up the chamber without technical ventilation (chap. 5.2.2).
9.1 Requirements for safe commissioning
Prior to turning on the chamber, the following points must certainly be met:
• Installation of the chamber (chap. 6) performed in compliance with the installation guidelines and ambi-

9.3 Sweeping the area for electrical equipment, the preheating chamber, and
the controller housing (triangular instrument box) with compressed air
To sweep the area for electrical equipment, the preheating chamber, and the controller housing, activate
the customer's compressed air supply.
The compressed air supply line provided by the operator must be equipped with active moni-
toring of the defined inlet pressure (2 bar), which clearly indicates a drop and increase in the
inlet pressure outside the permissible tolerance of ±0.2 bar.
9.3.1 Setting the pressure regulator for sweeping with compressed air
After opening the pressure regulator on the chamber rear (turn clockwise), the area for electrical equipment
of the oven, the preheating chamber (the heater area between the inner and outer chamber) and the con-
troller housing will be swept. Compressed air is used and then released into the surrounding atmosphere
independent of the oven’s operating state.
Compressed air sweeping must be in operation for a defined time (chap. 9.3.2) before turning on the cham-
ber. It remains in operation during the entire use of the chamber (loading, drying, removal of the material
to be dried), with an overpressure of at least 25 Pa (recommendation: >40 Pa). This operating point is
defined on the pressure regulator when the clamping ring touches the upper stop. After terminating the
drying procedure and turning off the chamber it is recommended to continue sweeping for approx. 10
minutes.
On the chamber front there is an analog pressure display (manometer) to show the existing overpressure.

9.3.2 Sweeping before starting up / restarting the chamber
Before turning on the VDL it is mandatory to sweep the area for electrical equipment, the preheating cham-
ber and controller housing with compressed air at maximum overpressure for a defined time.
Compressed air sweeping before start-up takes place in two steps. Be sure to follow the given
order.
Sweeping the electrical installation room, preheating chamber and controller housing (instrument
triangle)
• Turn the pressure regulator until the clamping ring touches the lower stop (turn clockwise). This gives
the maximum overpressure.
• Open the sweeping plug on the chamber rear next to the pressure regulator
• Check that compressed air flows out of the sweeping plug (caution, the outflowing air may be hot)
• Open the USB cover on the controller housing (instrument triangle)
• Check if compressed air is coming out of the USB cover (caution, the outflowing air may be hot)
• Sweep with maximum overpressure for at least the following duration
VDL 23: 20 minutes
VDL 56: 30 minutes
VDL 115: 40 minutes
• Then close the sweeping plug on the chamber rear.
• Also connect the USB cover on the controller housing (instrument triangle)
• Now the pressure regulator can be turned back (counter-clockwise rotation) until the clamping ring
touches the upper stop. (Only tighten to the stop by hand)
• Check that there is an overpressure of at least 25 Pa (recommendation: >40 Pa).
9.3.3 Sweeping during chamber operation
Sweeping the electrical installation room, the preheating chamber and controller housing must take place
with an overpressure of at least 25 Pa (recommendation: >40 Pa) during the entire operation of the vacuum
drying oven. This operating point is defined on the pressure regulator when the clamping ring touches the
upper stop. Also after termination or cancellation of the drying process continued sweeping for at least 10
minutes is recommended.

DANGER
Explosion hazard by solvent-containing air penetrating and concentration in the
electrical area of the chamber and at the heater.
Serious injury or death from burns and / or explosion pressure.
Make sure that sweeping the area for electrical equipment, preheating chamber, and
controller housing with compressed air for the defined time (chap. 9.3.2) at maximum
overpressure has been done before turning on the chamber.
Make sure that sweeping the area for electrical equipment, preheating chamber, and
controller housing with compressed air with an overpressure of at least 25 Pa (recom-
mendation: >40 Pa) takes place during the entire operation.
Ensure that the compressed air supply line provided by the operator is equipped with
active monitoring of the defined inlet pressure which clearly indicates a drop and in-
crease in the inlet pressure outside the permissible tolerance of ± 0.2 bar
Proceeding
• The sweeping plug on the chamber rear and the USB cover on the controller housing must be closed
• Adjust the pressure regulator until the clamping ring touches the upper stop. (Only tighten to the stop by
hand)

If the password function has been deactivated, after turning on the unit without user log-in there are those
controller functions available, which correspond to the highest authorization level without a password pro-
tection. There is no lock icon in the header.
9.7 Loading
Without technical ventilation the chamber must not be loaded with material containing sol-
vents.
The chamber cannot be loaded when turned off / in standby mode .
Before loading the material to be loaded, note:
When loading the chamber also in the context of intended use, an explosive mixture may form in the working
space. Therefore, a safety area of at least. 1 m in front of the oven must be considered.
• Ensure equipotential bonding. The accessible installation and operating surface of the equipment must
be conductive. This installation and operating surface must be connected with the vacuum drying oven
according to the grounding plan (Chap. 6.8).
• The personal protective equipment (PPE) of the operating personnel must be implemented ESD pro-
tected. This applies also to gloves.
• Activate the technical ventilation (extraction):
The operator shall provide active ventilation (technical ventilation according to country-specific regula-
tions (TRBS 2152 Part 2 for Germany) prior to commissioning of the chamber. It must include the entire
installation area of the vacuum drying oven. Loading must take place under technical ventilation in the
safety area in front of the oven.
• Introduce only those solvents for which the auto-ignition temperature and the maximum drying temper-
ature (safety temperature) have been determined and setting on the safety controller has been per-
formed.
Acc. to IEC 60079-0, only substances with an auto-ignition temperature above 200 °C / 392 °F may be
introduced into the chamber. This chamber is NOT suitable for drying substances with an auto-igni-
tion temperature below 200 °C.

VDL (E3.1) 10/2020 Page 92/196
DANGER
Explosion or implosion hazard and danger of poisoning by introduction of unsuita-
ble loading material.
Serious injury or death from burns and / or explosion pressure or by poisoning.
∅ Do NOT introduce any substance with an auto-ignition temperature below 200 °C /
392 °F into the chamber.
∅ Do NOT introduce any substance which is combustible or explosive at working temper-
ature into the chamber.
∅ Do NOT introduce energy sources such as batteries or lithium-ion batteries into the
chamber.
∅ Do NOT introduce any substance, which fall under the explosives law into the chamber
∅ Do NOT introduce any combustible dust into the chamber.
∅ Do NOT introduce any substance which could lead to release of toxic gases into the
chamber.
If the auto-ignition temperature of a solvent contained in the drying material is exceeded during the drying
process, there is an immediate risk of fire and explosion. Make sure that the auto-ignition temperature of a
solvent contained will NEVER be reached.
DANGER
Fire and explosion hazard when exceeding the auto-ignition temperature of the sol-
vent.
Serious injury or death from burns and / or explosion pressure.
Take the auto-ignition temperature from the safety specifications of the solvent. In the
case of solvent mixtures, use the lowest auto-ignition temperature.
Correctly set the maximum drying temperature (safety temperature) on the temperature
safety device according to the information panel “Temperature setting”.
Introduce measures to prevent mixing up the material to be dried.
Before starting a new drying process with a different auto-ignition temperature, check
the auto-ignition temperature with the safety specifications of the solvent.
If, during loading material containing solvents falls down, it is possible that the solvent or solvent vapors
will spread outside the loading area, e.g. to the side of or below the chamber. The chamber must be dis-
connected from the power immediately (pull out the power plug or operate e.g., a customer's emergency
stop switch).
The chamber is not to be installed and operated in potentially explosive areas.
DANGER
Explosion hazard due to explosive mixtures in the vicinity of the equipment.
Serious injury or death from burns and / or explosion pressure.
∅ Ensure that NO solvents or explosive solvent-air mixtures are located in the area
around the chamber.
Disconnect the chamber from the power immediately if there is explosive atmosphere in
the area around the chamber outside the indicated loading area.

VDL (E3.1) 10/2020 Page 93/196
9.8 Evacuation
Starting situation: The vacuum pump / vacuum system is connected and ready for operation.
Preparation:
• Make sure that the “Manual ventilation” plug (7) for emergency ventilationin case of a power failure,
which is located on the chamber rear, is closed
• Make sure that the pressure control is activated.
• Turn on the vacuum pump. The pump shall continue running during the entire drying procedure.
• Set the desired pressure set-point on the controller (chap. 10).
• Monitor the internal pressure on the controller display
As long as there is a vacuum, never try to open the oven by force.
9.9 Breaking the vacuum (flooding)
9.9.1 Ventilation after completing the drying procedure (flooding with ambient air or
inert gas)
The duration of the drying procedure can be determined via the pressure display on the controller. When
the decreasing pressure reaches the set-point value, the drying process is completed. If the drying moni-
toring (chap. 11.6) is activated, a corresponding message is displayed.
To break the vacuum (ventilation) after completing the drying procedure, set the desired pressure set-point
to atmospheric pressure (chap. 10). The ventilation valve opens, and ambient air or inert gas flow into the
inner chamber.
Regularly the universal connection for inert gas / ambient air “GAS/AIR” (4) is used for ventilation.
Chambers can be equipped as an option with an additional universal connection for inert gas / ambient air
“GAS/AIR2” (5), which can be used alternatively. To do this, the controller function “GAS/AIR 2” serves to
close the valve of the standard connection “GAS/AIR” (4). Then the valve of the optional connection
“GAS/AIR 2” (5) is used for ventilation (chap. 11.2). This allows convenient switching when both connec-
tions are used differently (e.g., for inert gas and ambient air).
Ambient air is sucked in through the universal connection for inert gas / ambient air (4) or (5). The ambient
air is introduced into the lower part of the rear panel of the inner chamber and is evenly distributed in the
inner chamber. This supply of ambient air by under-flooding prevents turbulence of pulverized drying ma-
terial.
Following ventilation, remove the loading material.
If no further drying process is to be carried out, switch the chamber to standby mode on the controller or
pull the mains plug to switch off the chamber completely.
9.9.2 Operation with inert gas
When operating the VDL vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the DGUV guidelines 213-850 on safe working in laboratories, issued by the
employers’ liability insurance association (for Germany).
During operation with inert gas, the chamber is supplied with an oxygen displacing gas (e.g. N
2
). Inert gases
in high concentrations are hazardous to health. They are colorless and almost odorless and therefore prac-
tically imperceptible. Inhalation of inert gases can cause drowsiness up to respiratory arrest. When the O
2
content of the air decreases below 18%, there is risk of death from lack of oxygen. Any gas that might
escape has to be led out via good room ventilation or a suitable exhaust system.

VDL (E3.1) 10/2020 Page 94/196
DANGER
Risk of suffocation due to high concentration of inert gas.
Death by suffocation.
∅ Do NOT set up chambers in non-ventilated recesses.
Ensure technical ventilation measures.
Respect the relevant regulations for handling these gases.
When decommissioning the vacuum drying oven, shut off the inert gas supply.
Install a pressure reducer for inert gas operation. Set the pressure reducer to a pressure slightly above
ambient pressure. Ensure that the pressure reducer will open. Do not change this setting in order to avoid
perturbation inside the oven and release of big quantities of inert gas after flooding the VDL.
Following evacuation, an inert gas, e.g., nitrogen, is led into the inner chamber via the connection
“GAS/AIR” (4) or the optional connection “GAS/AIR 2” (5) until pressure compensation with the atmosphere
occurs. Depending on the individual application, you can perform a second evacuation and repeat the inert
gas flooding.
When the inert gas fine dosing valve is open, a maximum of approx. 0.6 m³/h gas flows into the inner
chamber. The introduction of inert gas by under-flooding in the lower region of the inner chamber rear wall
and the extraction at the inner chamber ceiling allow an effective inert gas flushing.
9.9.3 Ventilation / breaking the vacuum in case of a power failure
The emergency ventilation is intended for the case of a completed drying process
To be able to open the chamber in case of a power failure, remove the “Manual ventilation” plug (7) for
emergency ventilation, which is located on the chamber rear.
As long as there is a vacuum, never try to open the oven by force.
Make sure that the drying procedure is complete before breaking the vacuum. Otherwise, you
should wait for the power to return to continue the drying procedure.
DANGER
Explosion hazard through the formation of an explosive atmosphere in the pres-
ence of hot surfaces.
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT remove the “Manual ventilation” plug, as long as the drying process is still run-
ning.
9.9.4 Ventilation before completing the drying procedure (flooding with ambient air or
inert gas)
If possible, avoid terminating the drying process. If it is nevertheless to be done, it is essential to observe
the following instructions!
Safety during the drying process: The vacuum during drying prevents the presence of an explosive
atmosphere in the interior of the chamber. At the start of the drying process, the heater is therefore only
released at a pressure of 100 mbar. In addition, the maximum temperature is limited so that, with correct
load, there is no risk of ignition from hot surfaces.

VDL (E3.1) 10/2020 Page 95/196
Error: If incorrect loading with an inadmissible solvent (auto-ignition temperature <200 ° C) has occurred,
proceed as follows
• Disconnect the power plug and turn off the pump.
• Let the chamber cool down to room temperature.
• Do NOT remove the “Manual ventilation” plug.
• Only ventilate when the interior temperature has cooled to room temperature. Only then open the door.
Hazard when opening the door after ventilation: After incorrect loading, open the door only when the
inner temperature has sunk to ambient temperature.
Prior to a termination of a not completed drying process make sure that the auto-ignition tem-
peratureof the solvent has been determined correctly, and that the drying temperature
reached far below this. In case of doubt, do not interrupt the drying process!
Proceeding to terminate the drying process:
• Set the temperature set-point to approx. ambient temperature
• Let the chamber cool down to ambient temperature
• Set the pressure set-point to approx. atmospheric pressure
DANGER
Explosion hazard through the formation of an explosive atmosphere in the presence
of hot surfaces after incorrect loading
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT use ambient air to break the vacuum as long as the chamber is hot. Do NOT
remove the “Manual ventilation” plug as long as the drying process is still running.
Let the chamber cool down to room temperature before opening the door.
9.10 Unloading the loading material
Do not unload the loading material without technical ventilation.
Note the following points before unloading the loading material:
When unloading the loading material also in the context of intended use, an explosive mixture may form in
the working space. Therefore, a safety area of min. 1 m in front of the oven must be considered.
• Activate Standby mode on the controller before opening the door.
• Ensure equipotential bonding: The accessible installation and operating area in front of the equipment
must be conductive. This installation and operating area must be connected to the vacuum drying oven
and other equipment according to the grounding plan (chap. 6.8).
• Activate the technical ventilation (extraction):
The operator shall provide active extraction (technical ventilation according to country-specific regula-
tions – TRBS 2152 Part 2 for Germany) prior to commissioning the oven. Extraction must include the
entire installation area of the vacuum drying oven. Unloading the loading material must take place in the
safety area in front of the oven with technical ventilation.
• The personal protective equipment (PPE) of the operating personnel must be implemented
ESDprotected.
• Sweep the area for electrical equipment, preheating chamber, and controller housing at least 10
minutes with compressed air (recommended).

VDL (E3.1) 10/2020 Page 96/196
9.11 Removing the full condensate catchpot of the pump
Do not remove the full condensate catchpot of the pump without technical ventilation
Note the following points before removing the condensate catchpot:
When removing the condensate catchpot spilling of the solvent may occur.
• Ensure equipotential bonding:
The accessible installation and operation area of the equipment must be conductive. This area and the
vacuum pump must be connected with the vacuum drying oven according to the grounding plan (Chap.
6.8).
• Activate the technical ventilation (extraction):
The operator shall provide active extraction (technical ventilation according to country-specific regula-
tions – TRBS 2152 Part 2 for Germany) prior to manipulating the condensate catchpot of the pump.
Extraction must include the entire installation area of the VDL and the vacuum pump, especially the area
of the catchpot (when removing it) and the exhaust air of the vacuum pump. Removing the full conden-
sate catchpot must take place under technical ventilation.
• Use ESD protected personal protective equipment:
The personal protective equipment (PPE) of the operating personnel must be implemented ESD pro-
tected. This includes also gloves.
9.12 Preparing a new drying process
Before starting a new drying process with a different auto-ignition temperature, determine the auto-ignition
temperature of the solvent according to its safety data sheet. In the case of solvent mixtures, use the lowest
auto-ignition temperature.
Check all settings (drying temperature, pressure set-point and safety controller setting). If appropriate,
make sure that the new temperature set-point and safety controller value are entered on the controller.
With each change of the temperature set-point, observe the safety controller setting.

VDL (E3.1) 10/2020 Page 97/196

Pressure 0 mbar up to 1100 mbar 0 mbar up to 1100 mbar
After starting the drying procedure, the heater is activated only when the pressure reaches or
falls below the required pressure threshold of 100 mbar.
Solvents and resulting vapors can ignite at excessive drying temperatures.
DANGER
Fire and explosion hazard when exceeding the auto-ignition temperature of the sol-
vent due to excess drying temperature.
Serious injury or death from burns and / or explosion pressure.
Make sure that only solvents with an auto-ignition temperature that is higher than
200 °C / 392 °F may be entered into the chamber. Check the auto-ignition temperature
with the safety specifications of the solvent. In the case of solvent mixtures, use the
auto-ignition temperature of the material with the lowest auto-ignition temperature.
In Fixed value operating mode, you can enter a temperature set-point, a pressure set-point, and the switch-
ing-state of special controller functions.
All settings made in Fixed value operating mode remain valid until the next manual change. They are saved
also when turning off the chamber or in case of toggling to Program Mode.

11.6 Drying monitoring
Pressure
Time
Figure 25: Schematic timing of the drying process and drying monitoring
Procedure:
• Enter the temperature set-point.
The previously entered pressure setpoint is not used with this function. It remains saved.
The drying monitoring uses a fixed minimum pressure setpoint.
• Start the drying monitoring: The vacuum pump is activated, the evacuation valve opens.
Starting from ambient pressure, the pressure starts to decrease.
• Depending on the vapor pressure of the solvent, a plateau phase is then reached
during which the
solvent vaporizes. The pressure remains almost constant.
• After the solvent is completely evaporated, drying is complete.
The pressure starts to decrease again
Without drying monitoring the pressure would now continue to decrease
, until the maximum final
vacuum is reached.
• The drying monitoring recognizes this second pressure drop. It turns off the pressure control. The cham-
ber will then be ventilated automatically
.
Prior to starting a new drying process, the pressure control must be activated again (chap. 11.4).
Notes:
If the drying monitoring is aborted during phase
or , the controller will take the current actual pressure
value as the pressure setpoint. This overwrites the previously entered pressure setpoint. It can be changed
manually at any time.
In processes with low temperatures < 40 °C or thermally poorly coupled items to be dried (e.g. drying of
powders), the drying monitoring may incorrectly identify the relevant parameters. In this case, please check
the process result and, if necessary, use a process not including this program for such processes.

12. Authorization levels and password protection
We recommend that you also assign a password to the "User" authorization level so that no
unauthorized person can use the chamber.
12.1 User management, authorization levels and password protection
The available functions depend on the current authorization level “Master”, “Service”, “Admin” or “User”.
The authorization levels are hierarchical: Every authorization includes all functions of the next lower level.
“Master” authorization level
• Highest authorization level, only for developers
• Extensive authorization for controller operation and configuration, outputs/inputs, alarm settings, param-
eter sets and operating ring display
• All passwords can be changed in the “log out” submenu (chap. 12.3).
“Service” authorization level
• Authorization level only for BINDER service
• Extensive authorization for controller operation and configuration, access to service data
• The passwords for “Service”, “Admin” and “User” authorization levels can be changed in the “log out”
submenu (chap. 12.3).
“Admin” authorization level
• Expert authorization level, for the administrator
• Authorization for controller configuration and network settings and for operating those controller func-
tions required for operating the chamber. Restricted access to service data.
• Password (factory setting): “2”.
• The passwords for “Admin” and “User” authorization levels can be changed in the “log out” submenu
(chap. 12.3).
“User” authorization level
• Standard authorization level for the chamber operator
• Authorization for operating the controller functions required for operating the chamber.
• No authorization for controller configuration and network settings. The “Settings” and “Service” sub-
menus of the main menu are not available.
• Password (factory setting): “1”
• The password for the “User” authorization level can be changed in the “log out” submenu (chap. 12.3).
As soon as a password has been assigned for an authorization level, the access to this level and the related
controller functions are only available after log-in with the appropriate password.
If for an authorization level no password is assigned, the related controller functions of this level are avail-
able for every user without login.
If passwords have been assigned for all authorization levels, access to the controller functions is locked
without login.

VDL (E3.1) 10/2020 Page 106/196
Operation after user login
At user login, the authorization level is selected
and confirmed by entering the respective pass-
word.
Following user login, controller operation is
available, recognizable by the open-lock icon in
the header. The available controller functions
correspond to the user’s authorization level.
Password protection activated for all levels: operation without user login is locked
If passwords have been assigned for all authori-
zation levels, the controller is locked without reg-
istration of a user.
As long as no user is registered, controller oper-
ation is locked, recognizable at the closed-lock
icon in the header. This requires that the user
management has been activated by the assign-
ment of passwords for the individual authoriza-
tion levels.
Password protection for at least one level deactivated: operation without user login is possible
If passwords have not been assigned for all au-
thorization levels, after turning on the chamber
there are those controller functions available,
which correspond to the highest authorization
level without password protection.
No lock icon is shown in the display header.
User login is neither required nor possible.
To activate the password protection and user
login, perform new password assignment (chap.
12.5.3).

are password protected (example: no protection for
the “User” and “Admin” levels) and no user has
logged in:
The user’s effective authorization (due to lack of
password protection) is shown.
Example: user with “Admin” authorization.
If passwords have been assigned for some or all of the authorization levels, user login (password entry)
provides the authorization for the corresponding password-protected level.

12.5.3 New password assignment for “service” or “admin” authorization level when the
password function was deactivated
If the password protection for an authorization level has been deactivated, i.e., no password is assigned,
no login for this level is possible. Therefore, access to this authorization level is available without login.
If the password for the “Service” or “Admin” authorization has been deleted (chap. 12.5.2), a new password
can be assigned for the current level and the next lower level(s) without user login.
Example: The password for the “Admin” authorization level was deleted, therefore every user without login
has full access to the functions of the “Admin” authorization level. If access to this level shall become
password protected again, the user can assign a new password for the “Admin” authorization level with the
“Password” function.

14. Temperature safety devices
14.1 Safety temperature limiter (TL) class 2
The safety temperature limiter (TL) serves to protect the vacuum drying oven, its environment and loading
material against exceeding the permitted temperature. It has a fixed switching threshold and prevents ex-
ceeding the maximum surface temperature of the inner chamber of 160 °C in the event of a fault. If this
temperature is exceeded, the heater turns off. The TL protects the VDL vacuum drying oven, its environ-
ment and the loading material against impermissible excess temperatures and prevents exceeding the
maximum drying temperature in case of a fault.
The safety temperature limiter (TL) provides temperature monitoring through a thermal switch (bimetal
switch). If the permissible temperature is exceeded, the heating is switched off and an additional self-hold-
ing circuit is activated, which is only reset when the power plug is removed and reconnected. This prevents
the heating from being automatically switched on again. When the TL is triggered, an alarm message is
displayed on the controller. An annual function check by the operator is recommended, for this a controller
test routine is provided (chap. 16.5).
The safety temperature limiter (TL) provides ignition source monitoring . For further information of its func-
tion as part of the manufacturer's safety plan, please refer to chap. 3.1.
14.2 Overtemperature safety controller class 2
The chambers are regularly equipped with an electronic overtemperature safety controller (temperature
safety device class 2 – temperature limiter) acc. to DIN 12880:2007). The safety controller protects the
chamber, its environment and the charging material against exceeding the maximum permissible temper-
ature. The safety device class 2 is electrically independent of the temperature controller and turns off the
chamber permanently.
In the event of a fault in the temperature controller, the safety controller turns off the vacuum drying oven
permanently, i.e. until manual alarm reset. This condition (state of alarm) is indicated visually and addition-
ally with an audible alert if the buzzer is enabled (chap. 16.4). You can turn off the buzzer with the OK
button / Confirm icon. The alarm persists until the chamber cools down below the configured safety con-
troller value.
Please observe the DGUV guidelines 213-850 on safe working in laboratories, issued by the employers’
liability insurance association (for Germany).
Check the setting regularly and adjust it following changes of the set-point or charge.
The temperature safety device only activates after the set-point has been reached once.
14.2.1 Safety controller mode
You can set the safety controller mode to “Limit” or “Offset”.
• Limit: Limit value, absolute maximum permitted temperature value
This setting offers high safety as a defined temperature limit will not be exceeded. It is important to adapt
the safety controller value after each modification of the temperature set-point. Otherwise, the limit could
be too high to ensure efficient protection, or, in the opposite case, it could prevent the controller from
reaching an entered set-point outside the limit range.
• Offset: Offset value, maximum overtemperature above any active temperature set point. The resulting
maximum temperature changes internally and automatically with every temperature set-point change.
This setting is recommended for program operation. It is important to check the safety controller set-
point and safety controller mode occasionally, as it does not offer a fix, independent limit temperature
value, which would never be exceeded.

VDL (E3.1) 10/2020 Page 121/196
Example:
Desired temperature value: 40 °C, desired safety controller value: 45 °C.
Possible settings for this example:
Temperature set point Safety controller mode Safety controller value
40 °C
Limit Limit value 45 °C
Offset Offset value 5 °C
Recommended setting: Safety controller mode “Limit”, safety controller value by approx. 5 °C above the
temperature set-point.
14.2.2 Setting the safety controller

16.5 Test alarm of the safety temperature limiter (TL)
The safety temperature limiter (TL) provides temperature monitoring with a fixed switching threshold. It is
an essential element of the manufacturer's safety plan to prevent ignition and explosions (chap. 3.1). There-
fore, an annual function check by the operator is recommended. To do this, you can use the controller test
routine described following. The test is performed on an empty chamber (without vacuum expansion racks
and rack holders).
If the ambient temperature is below 28 °C, the chamber must be heated up to 28 °C to 38 °C before starting
the test. To activate the heating, the chamber must first be evacuated below 100 mbar. This negative pres-
sure is maintained during the test.
For chambers equipped with a single safety temperature limiter (TL), this is tested with the setting “1”. For
chambers with 2 TB, the test is run twice, first with the setting “1” and then again with the setting “2”.

The chamber only starts heating if the current actual value of the unit has reached at least once a value
below 40 °C. The chamber continues heating until one of the following alarm messages appears:
• If the test is passed, the alarm message “Temperature limiter 1 triggered” will be displayed.
• If the test fails, the alarm message “Temperature limiter 1 error” is displayed.
To deactivate the test alarm, go back to the “Test temp. limiter” setting menu and set the value to “0” (test
alarm deactivated).
Then pull out the power plug und let the chamber cool down for 30 minutes. Plug in the power plug again
to return to normal chamber operation.
For the chambers with a single safety temperature limiter (TL), the test is completed here.
For the chambers with two safety temperature limiters (TL), carry out another test for the second TL. For
this purpose, the inner temperature must have cooled down to a value between 28 °C and 38 °C after the
first test.
Enter “2” in the “Test temp. limiter” setting menu to activate the test alarm for the second TL and press the
Confirm icon. Then proceed as described above.
The following table gives an overview of the maximum trigger times of the different chamber models.
If the safety temperature limiter is triggered before the end of this maximum trigger time, the test is consid-
ered passed. This corresponds to the alarm message “Temperature limiter 1 triggered” or “Temperature
limiter 2 triggered”.
After the maximum trigger time has expired, the test is considered as failed. This corresponds to the alarm
message “Temperature limiter 1 error” or “Temperature limiter 2 error”.

17. Timer program (stopwatch function)
During an entered duration the controller constantly equilibrates to the setpoints entered in Fixed value
operation mode (temperature, pressure, configuration of the special controller functions). This duration can
be entered as a “Timer program”. During the program runtime, any setpoint changes do not become effec-
tive; the controller equilibrates to the values which were active during program start.

18.7.2 Set-point ramp and set-point step
You can define the type of temperature and pressure transitions for each individual program section.
“Ramp” mode: Gradual changes of temperature and pressure
The set-point of a given program section functions as the section’s start temperature. During the section’s
duration, the set-point gradually passes to the set-point of the subsequent program section. The actual
value follows the continually changing set-point.
If the last program section is in “ramp” mode and the setpoint shall change within this section, then you
must program an additional section (with the shortest possible section duration) to provide the target tem-
perature of the last program section. Otherwise, the setpoint would remain constant during the section’s
duration.
Programming in the “ramp” mode allows all kinds of temperature and humidity transitions:
• Gradual changes of temperature and pressure
The setpoint changes its value gradually during the entered section duration. The actual value follows
the continually moving set-point at any time.
• Program sections with constant temperature and pressure
The setpoints (initial values) of two subsequent program sections are identical; so, the temperature and
pressure remain constant during the entire duration of the first program section.
• Sudden changes of temperature and pressure
Steps can be programmed in ramp mode as temperature or humidity changes (ramps) that occur during
a very short interval. If the duration of this transitional program section is very short (minimum entry 1
sec), the temperature or humidity change will proceed rapidly within the minimum amount of time.
“Step” mode: Sudden changes of temperature and pressure
The set-point of any program section functions as the section’s target value. At the start of the program
section, the unit heats up and evacuates / ventilates the chamber with the maximum speed to reach the
entered value; and then it holds it for the remaining section time. Therefore, the set-point temperature
remains constant for the section’s duration. These changes occur rapidly within the minimum amount of
time (minimum entry: 1 second).
Programming in the “step” mode allows only two kinds of temperature and pressure transitions:
• Programming gradual changes of temperature and humidity (ramps) is impossible in the “step” mode
• Program sections with constant temperature and pressure
The setpoints (target values) of two subsequent program sections are identical; so, the temperature and
pressure remain constant during the entire duration of the first program section.
• Sudden changes of temperature and pressure
The entered setpoint of the section is reached as fast as possible and then held constant for the remain-
ing section duration.

situated again within the entered tolerance limits, the program automatically continues. Therefore, the du-
ration of the program may be extended due to the programming of tolerances.
Programming of tolerances may extend program duration.
An entry of “-99999” for the tolerance minimum means “minus infinite” and an entry of “999999” for the
tolerance maximum means “plus infinite”. Entry of these values will never lead to program interruption. The
entry of “0” for the tolerance minimum and/or maximum deactivates the respective tolerance function.
When requesting rapid value transitions, we recommend not programming tolerance values in order to
enable the maximum heating-up speed.

-99999 to 99999. Confirm entry with Confirm icon. The controller returns to the section view.
Set the tolerance ranges for other parameters accordingly, if desired.
If one of the actual values (temperature and/or pressure) is outside the program tolerance range the whole
program course is interrupted. During this program interruption time the controller equilibrates to the set-
points of the current section.
The screen header indicates “Program pause (tolerance band)”. The program runtime indication flashes
and does not proceed any further.
When the temperature or pressure values are back within the entered program tolerance range, the pro-
gram continues automatically.
18.7.6 Repeating one or several sections within a time program
You can repeat several subsequent sections together. It is not possible to define the start section the same
time also as the target section, therefore you cannot repeat a single individual section.
Enter the desired number of repetitions in the field “Number of repetitions” and the number of the section
to start the repetition cycle with in the field “Start section for repetition” To have sections repeated infinitely,
enter the number of repetitions as “-1”.
The selected sections are repeated as many times as selected. Then the program continues.

23. Reference measurements
23.1 Checking the temperature in the inner chamber
The controller display was adjusted in the factory to the temperature in the center of the usable volume
(chap. 28.1). The sensor probe of the reference measuring device was connected tightly to an expansion
rack positioned in the middle of the chamber.
23.1.1 Checking the controller display
• Conduct the reference sensor into the inner chamber through the measuring port (12). The port must
be largely vacuum tight to enable a typical operation vacuum for the calibration. Use e.g., a silicone plug
with a hole for the sensor wire.
• Fix the sensor to the center of an expansion rack in the middle of the useable volume with adhesive
aluminum tape or thermal conductive paste to ensure sufficient thermal conductivity.
• Perform the measurement in a thermally stable condition with 3 expansion racks and empty oven.
• Equilibrating time: at least 12 hours.
23.1.2 Checking the spatial temperature exactitude
• Fix at least 9 sensor probes on 3 racks with adhesive aluminum tape or thermal conductive paste to
ensure sufficient thermal conductivity
• The distance of the sensor probes to all inner chamber walls must be at least 10% of the corresponding
inner chamber dimension (see DIN 12880:2007).
• Perform the measurement in a thermally stable condition with 3 expansion racks and empty oven.
• Response time: at least 12 hours.
Do NOT use the temperature probe of the reference measurement device without any con-
tact to the expansion rack, i.e., do NOT measure vacuum values!
In case the temperature probe is a thermo element, mount it so it is electrically insulated from
the rack.
If you note an excessive divergence between the controller and reference temperatures, please contact
BINDER Service to calibrate the temperature controller.

VDL (E3.1) 10/2020 Page 160/196
23.1.3 Checking the function of the manometer for compressed air sweeping
We recommend checking the manometer display for compressed air sweeping in the chamber door at least
once a year.
Via the outlet with sweeping plug for compressed air sweeping before start-up (11), the manometer display
in the door can be tested with a reference manometer.
• Remove the sweeping plug and attach a hose to the tube Ø 8 mm of the outlet (11).
• Open the USB cover on the controller housing (triangular instrument box)
• Use the pressure regulator to set a visible value on the manometer.
• Measure the pressure at the outlet (11) and compare it to the manometer display
The acceptable deviation between the manometer display of the chamber and the reference measuring
device is +/- 10 Pa.

24.3 Object temperature display with flexible Pt 100 temperature sensor (option)
The object temperature display permits recording the object temperature directly on or in the drying mate-
rial. This enables the determination of the actual temperature of the charging material during the whole
process. The object temperature is measured via a flexible Pt100 sensor inside the inner chamber and can
be viewed on the controller display. The sensor needs to be in thermally conducting contact with the charg-
ing material. It can be plunged into humid charging material up to the length of its protecting tube.
The intrinsically safe connection cable is firmly connected (via an isolation amplifier) to the connection
“Object temperature input” (3a) located in the VDL rear connection panel. This cable connection is realized
as a Lemo socket, which will be connected to a measuring access port on the measuring connection (12)
in the rear panel of the chamber.
24.3.1 Connection of the object temperature sensor
• Insert the Pt 100 temperature sensor from the rear through the measuring connection (12) into the inner
chamber.
• The 3 contacts of the Pt 100 sensor are conducted outside via a measuring access port. For reasons of
explosion protection, this electrical connection to the inner chamber is conducted via a triple internal
safety barrier with a conducting-state voltage of 1.6 Volt maximum against ground.
Technical data of the Pt 100 sensor:
• Three-wire technique
• Class B (DIN EN 60751)
• Temperature range up to 320 °C / 608 °F
• Stainless steel protective tube, length 45 mm / 1.77 in, stain-
less steel material no. 1.4501
