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.
-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.
-
8
-
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.
-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.
-
9
-
-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 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.
-
10
-
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.
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.

REFRIGERATION
Self-Contained Models
The self-contained models are shipped from the factory with a completely operational 290 refrigeration system and
require no modifications or adjustments upon installation. Case must be installed as per the installation section of this
manual to provide proper condensing air cooling.
The dual pressure control is used as a safety device and is factory set. The pressure control works on a differential.
The low-pressure side is a safety to protect the compressor in the case of refrigerant loss. The high-pressure side is
a safety to protect from system failure causing too high of system pressure.
Note: The condenser fan runs continuously.
This unit also has a defrost timer that will shut the compressor off a set number of times per day to ensure a full
defrost occurs. The compressor will remain off until the either the off time is reached or until the temperature sensor
on the coil reaches a set temperature, which ever happens first.
Self-Contained Refrigeration Operation
The unit temperature is controlled by an electronic control that senses air temperature and turns refrigeration on and
off as required to maintain proper temperature.
The electronic control will also sense a frosted coil that requires a defrost cycle and shuts off refrigeration until
defrost is complete. There are also a defined number of scheduled defrosts that also shut the refrigeration off to
insure a full defrost.

Remote Refrigeration Operation
The remote models manufactured before 12/1/19 are designed to use 134A refrigerant and after 12/1/19
are designed to use R531a refrigerant and shipped from the factory with the evaporator coil, expansion
valve, drier filter, sight glass and refrigerant solenoid valve. The required high-low-pressure control and
remote condenser can be provided as a factory option and will be required to be charged with 134a or
R531A refrigerant after installation.
The unit temperature is controlled by an electronic control that senses air temperature and opens and
closes the refrigerant solenoid valve as required to maintain proper temperature.
Once proper temperature is reached the solenoid valve closes and shuts off the refrigeration flow to the
unit and initiates a pump down cycle. This will allow the remote low pressure switch to open and shut off
remote compressor. The solenoid will remain closed until the electronic control probe reaches its “cut in”
set point. The electronic control will also sense a frosted coil that requires a defrost cycle and closes
-

-
solenoid until defrost is complete. There are also a defined number of scheduled defrosts that also insures
a full defrost occurs.
Remote Refrigeration Installation
The condensing unit and pressure control are optionally supplied from the factory for remote location
installation. A remote high low-pressure switch must be mounted and wired by the installer. The high low-
pressure switch must be wired in series with the compressor power supply as shown in diagram below.
1. Mount condensing unit as close to the remote display case as practical. All refrigeration and/or
electrical materials between the condensing unit and display case are to be supplied by installing
contractor.
2. Route properly sized and designed refrigeration lines from the condensing unit to the cabinet. Follow
line sizing charts and piping instructions in the condenser unit’s manufacturers instruction manual.
Horizontal suction lines should be pitched downward towards the condensing unit at least ½” per 10’
run to aid the oil drainage. A “P” trap must be installed in the suction line at the foot of every riser to
insure oil return. Dry nitrogen must be used to flow through tubing while brazing refrigeration lines.
3. Suction line must be insulated the entire length with Armaflex (or equivalent). Do not run liquid line
inside insulation with suction line.
4. The remote high/low-pressure control must be mounted, wired and set by the installer.
5. Leak check condensing unit, cabinet, and all connecting tubing. Cabinet and condensing unit tubing
should be checked to insure no leaks occurred during shipping or from rough handling.
Make certain all refrigeration valves are opened and evacuate system below 500 microns. System
must hold below 500 microns for 1 minute with pump isolated. Charge the system with refrigerant type
specified on the data plates.

Condensate Evaporator Pan and Pump
Condensate Evaporator (Standard Self-Contained Models)
NOTICE: During normal defrost cycles, steam from the condensate
evaporator may be visible around the case.
The standard Self-Contained case is furnished with an electric condensate evaporator. Plumbing
connections are not required.
-
16
-
The condensate evaporator can be removed from the case and the condensate drain can be plumbed to a
drain to conserve energy if desired. Disconnect the condensate evaporator wires at the condensate
evaporator to remove. This must be done by a qualified electrician.
Make sure that the drain line has not been dislodged during shipment and that the drain trap terminates
properly over the water reservoir.
Condensate Pump (Standard Remote, optional Self Contained)
When unit is shipped with a condensate pump a condensate discharge hose is supplied from factory. This
hose must be run to a nearby drain. When the condensate pan is full the pump will turn on and pump
water out condensate drain hose. Note Drain hose can be run in vertical direction but must not exceed
height of 15 feet
Note: There is a piece of cardboard that has to be removed from the side of the pump to free up the
float. If this is not done, the pump will not turn on and the pan will overflow.
Electronic Expansion Valve (EEV)
A traditional TXV uses springs and a temperature bulb to open and close a valve port that controls the flow
of refrigerant entering the evaporator coil. An electronic expansion valve (EEV) controls the refrigerant
flow much more precisely, increasing the performance and efficiency of the refrigeration system. The EEV
controls the flow of Refrigerant by opening and closing the valve port based on the response to signals
sent to the EEV by an electronic controller. The electronic Control bases these signals by processing
information provided from a temperature sensor and pressure transducer located on the discharge side of
the evaporator coil.
These sensors monitor the evaporator superheat and protects the compressor from any liquid flood back
under low superheat conditions.
EEV Controller Settings
The electronic expansion valve controller also allows the use of different types of refrigerants without the
need to change the expansion valve.
The controller is set from the factory to run on 449A refrigerant and will not need any changes to the
control unless another refrigerant is used.
Note: Check your State and Local regulations for approved refrigerants for your install location.
Federal Industries is not liable for any alternate refrigerants used.

ELECTRONIC CONTROL OPERATION (Refrigerated Models Only)
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 preset 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.
The temperature control is set to cut in at 39°F (3.9°C). The Temp control cuts out at 26°F (-3.3°C)
at the coldest setting “9” and 36°F (2.2°C) at the warmest setting “1”.
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 20°F
(11.1°C) 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 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 43°F
(6.1°C).
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.
Initial Startup
After all the checks outlined in the installation section of this manual have been made, the case is ready to
be put into service. Turn on the Power at the breaker box and flip the Power Switch and Light Switch on
unit to the on position. Also ensure that the control is powered on as described above.
(Refrigerated Models Only)
At start up from a warm unit, it is recommended that the temperature control is set to a mid-setting, such
as 5. After the unit has gone through several cycles, adjust the control to a warmer or a colder setting if

necessary to maintain desired product temperature. Allow refrigerated models to run for at least two hours
before placing pre-chilled product into display area.
Placing Product into Case
After completing shelving installation as outlined in “Shelving Installation and Removal” section of
this manual you may begin placing product into the display case.
- Do not exceed 100 pounds of weight per shelf. Heavy product should be distributed evenly
across the entire shelving area.
- Determine desired shelving location and angle before placing product in case. Product must be
removed to readjust shelf location and angle.
(Refrigerated Models)
- Do not overhang the front shelves with product. Product may overhang rear of shelf, but allow a
minimum of 1-1/2” between product and rear door. Improper clearance in front and rear of shelf will
block the refrigerated airflow and could cause product loss.
-Do not block the slots along the front or rear of the case display pan. Covering these slots will
block the refrigerated airflow and could cause product loss.
-The display pan is removable for cleaning and can become dislodged in shipment. To ensure
proper airflow and performance of the case, make sure that the display pan is pushed completely
down into evaporation tub. Check that the pan is installed properly before placing product the
display pans.
- Allow a minimum of 2” between the top of product and bottom of shelf.
-CASE SHOULD BE STOCKED WITH PRE-CHILLED PRODUCT ONLY.
NOTICE:
This refrigerated display case is designed to operate in a maximum environment of 75°F (23.9°C)
and 55% relative humidity. Exceeding these limits will cause poor case performance and
excessive sweating.

Special Service Situations
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 hydrofluorocarbons
(HFC’s) from being released into the atmosphere.
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 the moisture or
liquid. The investigation made should determine if the case is malfunctioning or if there is a simple
housekeeping problem.
NOTICE: 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.
