1. Qualification: All refrigeration and electrical maintenance, service, and repair must be performed
by a Certified Technician that is trained in the required flammable refrigerants safety procedures.
Technicians must read the entire section “REFRIGERATION WARNINGS SECTION” of this manual.
Including but not limited to the following:
a) breaking into the refrigerating circuit.
b) opening of sealed components.
c) opening of ventilated enclosures.
2.Checks to Area: Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS,
safety checks are necessary to ensure that the risk of ignition is minimized prior to conducting work
on the system.
-Capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparkling.
- No live electrical components and wiring are exposed while charging, recovering or purging the
system.
- Continuity of earth bonding.
-Work shall be undertaken under a controlled procedure to minimize the risk of a
flammable gas or vapor being present while the work is being performed.
E4036 UCR Page 8 of 35
-All maintenance staff and others working in the local area shall be instructed on the nature of the
work being carried out. Work in confined spaces shall be avoided.
-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.
-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 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 sufficiently 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.
-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.
-Where electrical components are being changed, they shall be fit for the purpose and to the correct
specification so as to minimize the risk of possible ignition due to incorrect parts. At all times, the
manufacturer’s maintenance and service guidelines shall be followed. If in doubt, consult the
manufacturer’s 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) Markings of the equipment continue to be visible and legible. Markings and signs
that are illegible shall be corrected.
d) Refrigerating pipes or components are installed in a position where they are
unlikely to be exposed to any substance which may corrode refrigerant containing
-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
An adequate temporary solution should be used. This shall be reported to the owner of the Initial
safety checks shall include:
3. 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 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.
E4036 UCR Page 9 of 35
-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 affected.
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 egress of flammable atmospheres. Replacement parts shall be in
accordance with the manufacturer’s specifications.
-Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this
will not exceed the permissible voltage and current permitted for the equipment in use.
NOTE The use of silicon sealants can inhibit the effectiveness of some types of leak detection
equipment. Intrinsically safe components do not have to be isolated prior to working on them.
4. Detection of flammable refrigerants: Under no circumstances shall potential ignition sources 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 recalibration.
(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 pipework.
NOTE Examples of leak detection fluids are
– bubble method,
– fluorescent method agents.
If a leak is suspected, all naked flames shall be removed/extinguished.
If a leakage of refrigerant is found which requires brazing, all the refrigerants shall be
recovered from the system, or isolated (by means of shut off valves) in a part of the system
remote from the leak.
5. Removal and Evacuation: When breaking into the refrigerant circuit to make repairs-or for any
other purpose-conventional procedures shall be used. However, for flammable refrigerants it is
important that the best practice be followed, since flammability is a consideration. The following
procedure shall be adhered to:
a. Safely remove refrigerant following local and national regulations.
b. Purge the circuit with inert gas.
c. Evacuate (optional for A2L).
d. Purge with inert gas (optional for A2L).
e. Open the circuit by cutting or brazing.
The refrigerant change shall be recovered into the correct recovery cylinders if venting is not allowed
by local and national codes. For appliances containing flammable refrigerants, the system shall be
purged with oxygen-free nitrogen to render the appliance safe for flammable refrigerants. This
process might need to be repeated several times. Compressed air or oxygen shall not be used for
purging refrigerant systems. For appliances containing flammable refrigerants, refrigerant purging
E4036 UCR Page 10 of 35
shall be achieved by breaking the vacuum in the system with oxygen-free nitrogen and continuing to
fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a
vacuum (optional for A2L). This process shall be repeated until no refrigerant is within the system
(optional for A2L). When the final oxygen-free nitrogen change is used, the system shall be vented
down to atmospheric pressure to enable work to take place. Ensure that the outlet for the vacuum
pump is not close to any potential ignition sources and that ventilation is available.
6. Charging procedures: In addition to conventional charging procedures, the following
requirements shall be followed.
a. Ensure that contamination of different refrigerants does not occur when using charging equipment.
Hoses or lines shall be as short as possible to minimize the amount of refrigerant contained in them.
b. Cylinders should be kept in an appropriate position according to the instructions.
c. Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system with
refrigerant.
d. Label the system when charging is complete (if not already).
e. Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM.
7. Decommissioning: Before carrying out this procedure, it is essential that the technician is
completely familiar with the equipment and all its details. 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 commences.
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 is 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 the 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 the 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 the site properly and all isolation valves on the
equipment are closed off.
k. Recovered refrigerant shall not be charged into another refrigerating system unless it has been
cleaned and checked.
8. Labeling: Equipment shall be labeled 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.
E4036 UCR Page 11 of 35
9.Recovery: When removing the refrigerant from a system, either for servicing or decommissioning, it
is recommended good practice that all refrigerants are removed safely.
When transferring refrigerant into cylinders, ensure that only appropriate refrigerant recovery
cylinders are employed. Ensure that the correct number of cylinders for holding the total system
charge is available. All cylinders to be used are designated for the recovered refrigerant and labeled
for that refrigerant (i.e., special cylinders for the recovery of refrigerant). Cylinders shall be complete
with pressure-relief valve and associated shut-off valve in good working order. Empty recovery
cylinders are evacuated and, if possible, cooled before recovery occurs.
The recovery equipment shall be in good working order with a set of instructions concerning the
equipment that is at hand and shall be suitable for the recovery of all appropriate refrigerants
including, when applicable, FLAMMABLE REFRIGERANTS. In addition, a set of calibrated weighing
scales shall be available and in good working order. Hoses shall be complete with leak-free
disconnect coupling and in good condition. Before using the recovery machine, check that it is in
satisfactory working order, has been properly maintained and that any associated electrical
components are sealed to prevent ignition in the event of refrigerant release. Consult manufacturer if
in doubt.
The recovered refrigerant shall be returned to the refrigerant supplier in the correct recovery cylinder,
and the relevant waste transfer note arranged. Do not mix refrigerants in recovery units and
especially not in cylinders.
If compressors or compressor oils are to be removed, ensure that they have been evacuated to an
acceptable level to make certain that FLAMMABLE REFRIGERANT does not remain within the
lubricant. The evacuation process shall be carried out prior to returning the compressor to the
suppliers. Only electric heating to the compressor body shall be employed to accelerate this process.
When oil is drained from a system, it shall be carried out safely.

E4036 UCR Page 14 of 35
7.3 CONDENSATE PUMP
A condensate pump is optional on all models. Installer must check unit to see if a condensate pump has been provided
with case.
WARNING TO INSTALLER:
Installer must determine if case was provided with condensate pump. Failure to hook up pump hose
to drain will cause water on floor and cause a slip hazard.
Instead of using heat energy to remove condensate run off from the evaporator coil a condensate pump moves the water to
a nearby drain.
The Condensate Pump is provided with 50ft of clear 1/2in OD x 3/8in ID tubing that must be run out of the base
area to a drain.
There are several drain tube exit locations provided in the base as noted in the drawing above. Plugs or caps will
need to be removed in the desired exit location.
The hose can be run the entire 50ft in any direction as required, but no higher than 20ft from the pump base. A
check valve is provided in the pump to prevent water from flowing back into the reservoir. For best efficiency
extend the hose level below the level of the pump base to create a siphoning effect. Never run the hose to or
through an area below freezing (32°F, 0°C) or freezing water will block the tube.

12.5 ELECTRONIC CONTROL OPERATION
This unit is equipped with an electronic temperature control. The control parameters are set at the factory and cannot be
manually changed in the field. The pre set control parameters are listed on the chart in the Settings Chart below.
Operation
The control uses two sensors, one located in the air stream and one located on the evaporator coil. The sensor
located in the air stream is referred to as the temperature control sensor. The sensor located on the evaporator coil
is referred to as the defrost probe.
The temperature control sensor is located on the plastic tub behind the evaporator coil to the left in the cold air
stream. The sensor location is critical for proper operation on the unit. Do not move or relocate this sensor.
The coil sensor is strapped to the evaporator coil. This sensor location is critical for proper operation of the unit.
Do not move or relocate this sensor.
Defrost Cycle
The control is programmed to initiate defrost via two different methods. There are 3 programmed defrost cycles in
the case which will initiate a defrost cycle every 8 hours. The unit does not have a time clock so the defrost cycles
cannot be set for any specific time of day.
The unit also has an ‘On demand’ defrost feature that will initiate a defrost when the temperature differential
between the evaporator temperature and the air temperature is more than the “defrost on demand differential” for
5 minutes after 30 minutes into the refrigeration cycle (e.g. if the air stream probe measures 42°F/5.6°C or greater
E4036 UCR Page 23 of 35
and the defrost probe measures 20°F/-6.7°C or lower for five minutes). Once initiated the defrost cycle will
terminate when evaporator coil sensor reaches the “defrost termination temperature”
If a manual defrost is required, one can be initiated by pressing and holding the down arrow for three (3) seconds.
This is typically unnecessary and should only be performed if special circumstances require it.
