WARNING
Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, safety checks are necessary to
ensure that the risk of ignition is minimized. For repair to the REFRIGERATING SYSTEM, the following steps shall be
completed prior to conducting work on the system.
Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or vapour being
present while the work is being performed.
General work area
All maintenance sta and others working in the local area shall be instructed on the nature of work being carried out.
Work in confined spaces shall be avoided.
Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is
aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is suitable for
use with all applicable refrigerants, i.e., non-sparking, adequately sealed, or intrinsically safe.
Presence of fire extinguisher
If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate fire extinguishing
equipment shall be available on hand. A dry chemical or CO2 fire extinguisher should be adjacent to the charging area.
No ignition sources
No person carrying out work in relation to a REFRIGERATING SYSTEM which involves exposing any pipe work shall use
any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources,
including cigarette smoking, should be kept suciently far away from the site of installation, repairing, removing and
disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work taking place, the
area around the equipment shall be surveyed to make sure that there are no flammable hazards or ignition risks. “No
Smoking” signs shall be displayed.
Ventilated area
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting any
hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should
safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
Checks to the refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At
all times, Vollrath® maintenance and service guidelines shall be followed. If in doubt, consult the Vollrath® technical
department for assistance.
The following checks shall be applied to installations using FLAMMABLE REFRIGERANTS:
A. The actual REFRIGERANT CHARGE is in accordance with the room size within which the refrigerant containing parts are
installed,
B. The ventilation machinery and outlets are operating adequately and are not obstructed,
C. If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant,
D. Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected,
E. Refrigerating pipe or components are installed in a position where they are unlikely to be exposed to any substance
which may corrode refrigerant containing components, unless the components are constructed of materials which are
inherently resistant to being corroded or are suitably protected against being so corroded.
Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures.
If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily
dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary
solution shall be used. This shall be reported to the owner of the equipment, so all parties are advised. Initial safety checks
shall include:
A. That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking;
B. That no live electrical components and wiring are exposed while charging, recovering or purging the system;
C. That there is continuity of earth bonding.

WARNING
Repairs to sealed components
During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being worked
upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an electrical supply to equipment
during servicing, then a permanently operating form of leak detection shall be located at the most critical point to warn of
a potentially hazardous situation.
Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is not
altered in such a way that the level of protection is aected. This shall include damage to cables, excessive number of
connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
Ensure that the apparatus is mounted securely.
Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose of
preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the manufacturer’s
specifications.
Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges, or any other
adverse environmental eects. The check shall also take into account the eects of aging or continual vibration from
sources such as compressors or fans.
Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant
leaks. A halide torch (or any other detector using a naked flame) shall not be used.
The following leak detection methods are deemed acceptable for all refrigerant systems:
Electronic leak detectors may be used to detect refrigerant leaks but, in the case of FLAMMABLE REFRIGERANTS,
the sensitivity might not be adequate, or might need re-calibration. (Detection equipment shall be calibrated in a
refrigerant-free area.) Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant
used. Leak detection equipment shall be set at a percentage of the LFL of the refrigerant and shall be calibrated to
the refrigerant employed, and the appropriate percentage of gas (25 % maximum) is confirmed.
Leak detection fluids are also suitable for use with most refrigerants but the use of detergents containing chlorine
shall be avoided as the chlorine can react with the refrigerant and corrode the copper pipe-work.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or
isolated (by means of shut o valves) in a part of the system remote from the leak.

WARNING
Decommissioning
Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all
its detail. It is recommended good practice that all refrigerants are recovered safely. Prior to the task being carried out,
an oil and refrigerant sample shall be taken in case analysis is required prior to re-use of recovered refrigerant. It is
essential that electrical power is available before the task is commenced.
A. Become familiar with the equipment and its operation.
B. Isolate the system electrically.
C. Before attempting the procedure, ensure that:
i. Mechanical handling equipment is available, if required, for handling refrigerant cylinders;
ii. All personal protective equipment is available and being used correctly;
iii. The recovery process is supervised at all times by a competent person;
iv. Recovery equipment and cylinders conform to the appropriate standards.
D. Pump down refrigerant system, if possible.
E. If a vacuum is not possible, make a manifold so that refrigerant can be removed from various parts of the system.
F. Make sure that cylinder is situated on the scales before recovery takes place.
G. Start the recovery machine and operate in accordance with instructions.
H. Do not overfill cylinders (no more than 80 % volume liquid charge).
I. Do not exceed the maximum working pressure of the cylinder, even temporarily.
J. When the cylinders have been filled correctly and the process completed, make sure that the cylinders and the
equipment are removed from site promptly and all isolation valves on the equipment are closed o.
K. Recovered refrigerant shall not be charged into another REFRIGERATING SYSTEM unless it has been cleaned and
checked.
L. Labelling: Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The
label shall be dated and signed. For appliances containing FLAMMABLE REFRIGERANTS, ensure that there are
labels on the equipment stating the equipment contains FLAMMABLE REFRIGERANT.
