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.
4.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.
Page | 7
-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.
-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:
Page | 8
5. 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.
-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.
8. 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.

9. 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 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.
10. 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.
11. 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.
Page | 10
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.
12. 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.
13.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.

You may avoid the cost and inconvenience of an unnecessary service call by first
reviewing this checklist of frequently encountered situations that can cause
unsatisfactory case performance.
Pre-Service Checklist
Case Does Not Operate
Check for disconnected power supply.
Check that power switch is “on”.
Case Temperature Too Warm
Check that top air discharge opening and/or bottom air intake grille are not
blocked.
Check for a blocked or dirty condenser coil.
Check that there are no outside air disturbances in or around case. These
disturbances can be caused by nearby doors or entrances, overhead ceiling fans,
or air diffuser vents, direct sunlight or other heat sources. The location of open
refrigerated merchandisers is critical to case performance.
Make sure that warm product is not being placed inside case. All products must
be pre-chilled prior to loading for proper case performance.
Check temperature/pressure control for proper settings.
Check cold air flow. Lack of, or no air flow may indicate a blocked evaporator coil
or defective evaporator fan motor. Contact a qualified service company if there is
no air flow inside the case.
Lights Do Not Operate (Optional Equipment)
Check that light switch is “on”.
Check that light bulb(s) are properly seated in light holders.
Overflow of Condensate Evaporator
Check that there is a power supply to the condensate evaporator assembly. On
self-contained models this is on a separate electrical circuit.
Check that the drain line is properly located over the water reservoir.
Check room ambient conditions. The room environment should not exceed 75F
ambient and 55% humidity conditions.
WARNING: Before servicing case turn off power at the
main breaker of fuse box.

Special Service Situations
IMPORTANT: Read this Section of this manual located on page 5.
“REFRIGERATION WARNING &INSTALLATION-REPAIR-DECOMMISSIONING”
All refrigeration and electrical work must be performed by certified technicians
There are rare occasions when the refrigerant charge must be evacuated from a case in
order to perform service work. In those situations, Federal Industries recommends that
the refrigerant charge be evacuated into a recovery system to prevent the possibility of
hydrochlorofluoracarbons (HCFC’s) from being released into the atmosphere. The
release of HCFC’s into the atmosphere is a potential source of global warming.
If moisture or liquid is observed around or under a Federal Industries case, an immediate
investigation should be made by qualified personnel to determine the source of moisture
or liquid. The investigation made should determine if the case is malfunctioning or if
there is a simple housekeeping problem.
Moisture or liquid around or under a case is a potential slip/fall hazard for persons
walking by or working in the general area of the case. Any case malfunction or
housekeeping problem that creates a slip/fall hazard around or under a case should be
corrected immediately.

All refrigeration and electrical work must be performed by certified technicians
If you sell or give away your Federal Industries case, you must make sure that all safety
labels and the Installation-Service Manual are included with it. If you need replacement
labels or manuals, Federal Industries will provide them free of charge. Contact the
Customer Service Department at Federal Industries at 1(800)356-4206.
The Customer Service Department at Federal Industries should be contacted at the time
of sale or disposal of your case so records may be kept of its new location.
If you sell or give away your Federal Industries case and you evacuate the refrigerant
charge before shipment, Federal Industries recommends that the charge be evacuated
into a recovery system to reduce the possibility of HCFC’s from being released into the
atmosphere. The release of HCFC’s into the atmosphere is a potential source of ozone
depletion.
Refrigerant Recovery/Recycling/Disposal
When recycling or discarding case, refrigerants MUST BE handled according to local,
state and federal codes, requirements and regulations.
If disposing of a refrigerated case that uses ozone depleting chemicals in its refrigeration
system, make sure the refrigerant is removed by a qualified service technician and
properly disposed of.
If you intentionally release refrigerant into the atmosphere, you may be subject to fines
or other penalties (under regulation mandated by environmental regulators and/or
legislative edict.)
