5.2 EVAPORATOR CONDENSATE DRAIN
WARNING TO INSTALLER:
Evaporator Condensate Drain Tube may become dislodged during shipping. Installer must check
Evaporator Condensate Drain Tube upon installation to be sure drain tube is properly seated and
installed correctly.
Evaporator Drain must be attached to tube protruding from bottom of Evaporator Tub and must either be inside the
Condensate Pan area or inside of hole of Condensate Pump.
5.3 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.

10.5 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.
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
Page 17 of 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.

10.7 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.
At start up from a warm unit, it is recommended that the temperature control is set to a warmer setting, such as 1. After
the unit has gone through several cycles, adjust the control to a mid-range setting, then to a colder setting if necessary to
maintain desired product temperature
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.
Page 18 of 30
10.8 PLACING PRODUCT IN CASE
Determine desired shelving location before placing product in case. Product must be removed to readjust shelf
location and angle.
Do not overhang the front or rear of shelves with product. Improper clearance in front and rear of shelf will block
the refrigerated air flow and will cause product loss.
Do not block the slots along the front and rear air discharge slots. Covering these slots will block the refrigerated
air flow and will cause product loss.
The display deck is removable for cleaning and can become dislodged in shipment. To ensure proper airflow and
performance of the case, make sure that the display deck is pushed completely down into the plastic evaporator
tub.
Allow refrigerated models to run for at least two hours before placing pre-chilled product into unit.
NOTICE:
Case must be stocked with pre-chilled product only. Product should be at or below 40°F (4.5°C)
before adding it to the display case. Use a refrigerator to pull down product that is above 40°F
(4.5°C). This display case is a temperature holding product only. It will not pull down product that
is above the recommended temperature.

15.1 SPECIAL SERVICE INSTRUCTIONS
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 hydrofluoro olefin (HFo’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.
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.
