Required Safety Checks:
Prior to beginning work on systems containing FLAMMABLE REFRIGERANTS, perform the following
safety checks to ensure that the risk of ignition is minimized prior to conducting work on the
system.
☐ Discharge all capacitors using safe, non-sparking method to prevent accidental arcing.
☐ Ensure no live electrical components or wiring are exposed during charging, recovering or
purging.
☐ Confirm continuity of earth bonding.
☐ Ensure all personnel (direct, contracted, etc.) in the area are informed of the nature of the work
being performed.
☐ Ensure the work area is open or adequately ventilated.
o Ensure ventilation is maintained during work.
o Ventilation should disperse any released refrigerant and preferably discharge it
externally to atmosphere.
o Work in confined spaces shall be avoided.
LMD E3670-20 9
☐ Survey the surrounding area to ensure there are NO flammable hazards, ignition sources, or
other unsafe conditions present.
o All possible ignition sources, including cigarette smoking, shall be kept sufficiently
far away from the site of installation, repairing, removing and disposal, during which
refrigerant can potentially be released to the surrounding area.
o “NO Smoking” signs shall be posted and visible.
☐ Check the area with an appropriate refrigerant detector prior to and during work to ensure the
technician is aware of potentially toxic or flammable vapors.
o Ensure that the leak detection equipment being used is suitable for use with all
applicable refrigerants (e.g., non-sparking, adequately sealed, or intrinsically safe)
o NOTE: The use of silicon sealants can inhibit the effectiveness of some types of leak
detection equipment.
☐ Work shall follow a controlled procedure that prevents release or accumulation of flammable
gas or vapor throughout the process.
☐ No person performing work to or near a REFRIGERATION SYSTEM that 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.
☐ Verify the actual REFRIGERANT CHARGE is in accordance with the room size within which the
refrigerant containing parts are installed.
☐ Verify the ventilation machinery and outlets are operating adequately and are not obstructed.
☐ Verify markings on the equipment continue to be visible and legible.
o Markings and signs that are illegible shall be corrected.
☐ Verify refrigerating pipes and components are installed in a position where they are unlikely to
be exposed to any substance which may corrode refrigerant containing
Hot Work Controls

☐ Recover or isolate refrigerant prior to beginning hot work (See part 0 of this section)
☐ Appropriate fire extinguishing equipment shall be made readily available before starting work.
☐ A dry chemical or CO2 fire extinguisher should be adjacent to the charging area.
☐ The area shall be adequately ventilated before and during any hot work to safely disperse any
released refrigerant.
Electrical Components
☐ Electrical components being changed shall be suitable for the purpose and to the correct
specification so as to minimize the risk of possible ignition due to incorrect parts.
o At all times, the manufacturer’s maintenance and service guidelines shall be
followed.
o If in doubt, consult the manufacturer’s technical department for assistance.
LMD E3670-20 10
☐ If a fault exists that could compromise safety, then no electrical supply shall be connected to
the circuit until it is satisfactorily resolved. If the fault cannot be corrected immediately but it is
necessary to continue operation, an adequate temporary solution should be used.
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.
o 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.
☐ Measures shall be taken to ensure that work on electrical components does not alter the
casing in such a way that it compromises its level of protection. This includes preventing:
o Damage to cables;
o Excessive number of connections;
o Terminals not made to original specification;
o Damage to seals;
o Incorrect fitting of glands;
o etc.
☐ Ensure that the apparatus is mounted securely.
☐ Ensure that seals or sealing materials have not degraded to the point that they no longer
prevent the egress of flammable vapors.
☐ Replacement parts shall be in accordance with the manufacturer’s specifications.
Repairs to intrinsically safe components
Note: Intrinsically safe components do not have to be isolated prior to working on them
☐ 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.
☐ Replacement parts shall be in accordance with the manufacturer’s specifications to ensure
that the risk of ignition is minimized,
Safe 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.
o Detection equipment shall be calibrated in a refrigerant-free area.
o Ensure that the detector is not a potential source of ignition and is suitable for the
refrigerant used.
LMD E3670-20 11
o 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. Examples of leak detection fluids are
o bubble method,
o 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.
Removal and Evacuation:
Prior to breaking into the refrigerant circuit for any purpose, the following procedure shall be
adhered to due to the added flammability risk:
a) Safely remove refrigerant following local and national regulations.
b) Purge the circuit with oxygen-free nitrogen (OFN).
c) Evacuate (optional for R454C).
d) Purge the circuit with oxygen-free nitrogen (OFN) (optional for R454C).
e) Open the circuit by cutting or brazing.
The refrigerant shall be recovered into the correct recovery cylinders.
Due to use of 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.
o Compressed air or oxygen shall not be used for purging flammable refrigerant
systems.
For appliances containing flammable refrigerants, refrigerants 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 R454C). This process shall be repeated until no refrigerant is within the
system (optional for R454C). When the final oxygen-free nitrogen charge 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.
LMD E3670-20 12
Charging procedures:
In addition to conventional charging procedures, the following requirements shall be followed.
☐ 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.
☐ Cylinders should be kept in an appropriate position according to the instructions.
☐ Ensure that the REFRIGERATING SYSTEM is earthed prior to charging the system with
refrigerant.
☐ Label the system when charging is complete (if not already).
☐ Extreme care shall be taken not to overfill the REFRIGERATING SYSTEM.
Prior to recharging the system, it shall be pressure-tested with the appropriate purging gas. The
system shall be leak-tested on completion of charging but prior to commissioning. A follow up
leak test shall be carried out prior to leaving the site.
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.
LMD E3670-20 13
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.
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.

Two Cases Connected to Single Remote Condenser
If (2) cases are ordered from factory to run on a single condensing unit, there is only one
control that will operate both units.
The cases are prewired to connect both refrigeration solenoids together. These Wires are
hanging out from joining side of each case near the top front behind canopy.
Once all prep work is complete and both cases are ready to be joined, connect the wires from
each case together. Connect the yellow wire from case 1 to yellow wire to from case 2 and
connect the white wire from case 1 to white wire from case 2.
Once connected join cases as described below. Be careful not to pinch the wires between
cases.

LMD E3670-20 24
Floor Preparation
Be sure the floor where the case line up will be located is strong enough to support cases
without sagging.
It is important that the cases are level. This will allow for proper drainage of condensate water
from evaporator coil and allow for proper alignment of cases.
Most floors are not level and the high and low spots in location of cases must be determined.
Place a chalk line in the desired position of where the back of the cases will be located. If the
back of the cases are to be along a wall there should be at least 6” clearance between wall and
the back of the cases.
Measure 33.25” from this chalk line to where the front of cases will be. This line is where the
front base rail meets the floor not the actual front of the case.
Mark the location along these lines that the outside edges of case will be. The cases without
end panels will be 48”,72”, or 96” depending on cases ordered. Add additional 1” to case end
that has an end panel.
Use a transit or line level to determine the highest point along chalk line.
Joining and Leveling Line Up
If case line up is along a wall it will make it difficult to gain access to back of case once line up
is complete. If it all possible make all connections accessible from front under side of cases,
but if necessary make any required connections at back of case as you install the cases.
-There are factory installed gaskets located on each end of all adjoining cases. Inspect all
gaskets to be sure they are properly located and not damaged.
-Remove the front kick plates from all cases as described Panel Removal section of this

G) OPERATING INSTRUCTIONS
CONTROL DESCRIPTION
Light Switch
The unit has a light switch that turns on and off the interior lights of unit.
Electronic Temperature Control
Located in the rear grille of the display case, the temperature control allows the user to adjust the
temperature of the display merchandiser to their needs.
LMD E3670-20 33
ELECTRONIC TEMPERATURE 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 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.

REFRIGERANT DETECTION AND MITIGATION SYSTEM
The refrigerant detection system (RDS) shuts down the operation of the refrigerator when a leak is
detected. The system is comprised of 2 or more sensors, a low voltage power supply, 1-2 safety
shutoff solenoid valves, and 1-2 refrigerant check valves.
When a leak is detected by one of the sensors, the internal sensor relay opens to shut off the
safety solenoid valve(s). The refrigeration check valve prevents any back flow from the rest of the
external system from entering the unit that would further contribute to a leak.
Please note that once a leak is detected and the flow of refrigerant is stopped, the display case
will stop cooling, and any temperature sensitive products must be removed from the unit.
This display case’s fans are a part of the leak mitigation system and are required to remain
powered on as long as there is power to the display case. In the event of a refrigerant leak, the
unit’s fans are required to run to reduce the concentration of flammable refrigerant in and around
the unit. When replacing gas detection sensors, only replace with the original model of sensor
provided by Federal.
To replace a faulty sensor, simply remove unplug the electrical quick connection and unscrew the
sensor fasteners and attach the new sensor to the original sensor location in the original
orientation.
After replacing installing the new sensor, power on the display case. After a few seconds, the
sensor light will begin to blink green. See illustration above. The refrigeration system will be
allowed to run as normal.
The sensor is capable of a long life and will monitor its condition to ensure functionality. If the
sensor’s self-monitoring system detects an issue it will go into a fault state and shut off the flow of
refrigerant to the appliance. See above illustration for fault indication on LED.
The gas inlet exposes the sensing element of the sensor to surrounding gases. The opening in the
sensor housing exposes the humidity and temperature sensors inside the sensor to the
environment and makes them susceptible to pollutants such as volatile chemicals, acids, bases,
cleaning and foaming agents. Exposure to those pollutants should be avoided. Cleaning products
might damage the sensor or temporarily block its gas inlet, inhibiting or delaying the response to
the refrigerant.
LMD E3670-20 38
The use of solvent emitting materials near the sensor, such as PVC cement glues, may lead to
nuisance trips. Solvent emitting materials can lead to high concentrations of volatile gas in the
nearby environment. The gas sensor may sense these concentrations, and trigger a system
mitigate response. Please note that the safety shut-off valve system is installed at the factory. No
safety shut-off valves are required to be installed in the field on new equipment.

BEFORE SERVICING UNIT
LMD E3670-20 47
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.

Remote Low Press. Switch Cut Out
15 psi
Adjustable Head Master
200 psi
Remote High Press. Switch Cut Out
400 psi
The remote models are designed to use R454C refrigerant and shipped from the factory with the
evaporator coil, expansion valve, and refrigerant solenoid valve. Drier filter must be installed in
field for proper operation. Electronic control opens and closes a refrigeration solenoid valve
located on the suction line 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 condensing unit and pressure controls are optionally supplied from the factory for remote
location installation. The condensing unit 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 indoors as close to the remote display case as practical. The
refrigeration line should be as short as possible and must not exceed 30 feet.
2. All refrigeration and/or electrical materials between the condensing unit and display case are
to be supplied by installing contractor.
3. Route properly sized and designed refrigeration lines from the condensing unit to the cabinet.
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.
4. Suction line must be insulated the entire length with Armaflex (or equivalent). Do not run liquid
line inside insulation with suction line.
5. The remote high/low-pressure control must be installed and set pressures by the installer.
6. 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 to 500 microns. Charge
the system with refrigerant type specified on the data plates.

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 454C refrigerant (code 54C) and will not need to be
changed unless another refrigerant is used.
NOTE: On units with older model EEV’s, the EEV is set to code 40C
Note: Check your State and Local regulations for approved refrigerants for your install
location. Federal Industries is not liable for any alternate refrigerants used.
The control is located in the front left corner of evaporator tub under the Display Deck Pan.
Note: Never change any of the other setting other than the refrigerant type. It may also be
necessary to change the superheat setting only when using a different refrigerant.
Changing Refrigerant
• Access the set point mode by pressing and holding the button until Ctl displays on the
screen.
• Use the up or down arrows to advance through the available set points until rFG
displays on the screen and press the botton.
• Use the up or down arrows until the desired refrigeration displays on the screen and
press and hold the button until rFG once again displays on the screen.
• Press the to return to escape the settings menue.

screen.
• Use the up or down arrows to advance through the available set points until SSP
displays on the screen and press the botton.
• Use the up or down arrows to set the desired superheat displays on the screen and
press and hold the button until SSP once again displays on the screen.
• Press the to return to escape the settings menue.
