Condensate Pump Standard
The pump is mounted in the base compartment and is designed to automatically
remove the condensate water that collects from defrosting the evaporator coil. The
pump has a built-in tank that collects water from the evaporator coil defrost cycle. When
the pump tank is full the pump switches on and pumps water to a remote location for
disposal. When the tank is empty the pump automatically switches off.
The pump is capable of lifting water to a maximum of 20’.
Condensate Discharge Hose.
The case is provided with a 25’ of 3/8ID clear flexible tubing. Depending on options it is
either coiled up on top of the case or in the base compartment.
Hose Coiled in Base
Disconnect Power: Access the hose located in base compartment by removing one
of the base side panels. The hose can be routed to the nearest remote drain through
one of the provided openings or holes Do not run hose in heavy traffic areas and be
sure hose does not get kinked or pinched.
Hose Coiled on Top
Hose coiled on top of the unit is designed to be run vertical to the ceiling before
being routed to the nearest remote drain. The maximum vertical height the hose can
run is 20’ from floor. Once the hose turns to a horizontal direction the hose must
have a downward slope to avoid low spots that water can collect. Be sure the hose
does not get kinked or pinched.

Condensate Evaporator Pan Shipped Loose (OPTION)
If the optional high output condensate pan was ordered it will be shipped loose in a
separate box. This high output pan must be field mounted and wired by a licensed
electrician.
If there is already a factory condensate pan and mounting brackets installed in the base
compartment they must be removed before installing the optional high output pan.
Unwire the heater wires from the 2x 4 electrical box and cap remaining wire ends with
UL approved wire nuts. NOTE: THESE WIRES CAN NOT BE CONNECTED TO THE FIELD
INSTALLED HIGH OUTPUT PAN.
Mount the high output condensate pan inside the base
compartment so that the (2) condensate drain tubes drain
directly into the pan as shown in photo.
The field installed high output condensate pan must be wired
to its own designated circuit breaker and cannot be wired into
the same circuit breaker that the display case uses. The
display case circuit and wiring are not sized to handle the
extra amperage of the high output condensate pan.
See label on condo pan for proper circuit sizing.
- Bottom Electrical (standard): There is cord and plug provided on the high output
condensate pan. a licensed electrician must provide a designated receptacle to plug in
the high output condensate pan. There are access holes in various locations in the base
enclosure to run wires out of the case to electrical source.
-Top Electrical (optional): There is also a top wiring condensate pan option that provides
a top electrical box on the top side of the canopy. This allows wires to be run to the
store ceiling. There are (2) sets of wires, “main case wiring” and “condensate pan
wiring”. Each circuit is labeled and must run to separate circuits. The condensates pan
wires run down through the case into a 2 x 4 electrical box in the base compartment. A
licensed electrician will need to provide a designated receptacle to plug in the high
output condensate pan.

CONTROL OPERATION
Electronic Control
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. Control parameter
changes can only be made by downloading a new set of parameters via a program chip
supplied by Federal Industries.
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 coil
sensor.
The temperature control sensor is located inside the center tower at the top. 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 degrees F. The Temp control cuts out at
14 degrees F at the coldest setting “9” and 28 degrees F at the warmest setting, ‘1’ on
the control display.
The temp control turns off the refrigeration system when you “press and hold” the top
arrow / power button for approx. 3 seconds until “OFF” flashes on display.
Defrost Cycle
The CAREL 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 15 degrees for 5 minutes after 30 minutes into the refrigeration cycle.
Maximum Run Timer
The unit is equipped with a maximum run timer that is preset at the factory for 75
minutes on. If the temperature control does not reach cut out set point after running for
one hour, the timer will turn the compressor off for a minimum of 2 minutes.

REFRIGERATION OPERATION
Self-Contained Models
7.5 Pounds
The self-contained models are shipped from the factory with a completely operational R449A
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.
Dual Pressure Control (Self-Contained Models Only)
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. As of 8/1/14 ECSS60 only has integrated dual pressure control on
condensing unit.
The high side of the pressure control is factory set to 400psi and is not adjustable. Low
side setting for the R449a cases are set at 40psi differential for the cutout and 60psi for
the cut-in.
Self-Contained Refrigeration Operation
The unit temperature is controlled by the Electronic control and timers outlined in the control
section of this manual.
Note: The condenser fan runs continuously.

installed in field for proper operation. Electronic control runs identical to the Self-Contained
models except the electronic control opens and closes a refrigeration solenoid valve located on
the suction line instead of turning on and off a compressor. 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 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.
Remote Condensing Unit Installation
1. Mount condensing unit as close as possible to the remote display case as practical. Follow
condensing unit manufacturer guidelines for proper piping and distance requirements.
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 mounted, wired 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) After 12/1/19
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.
The control is located on the left side of the case.
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.

MAINTENANCE
Cleaning Condenser Coil
NOTICE: Condenser coil or optional air filter must be cleaned a
minimum of twice per month to insure proper refrigeration
performance and prevent compressor failure. In some
environments, it may be necessary to clean more frequently.
FAILURE TO CLEAN CONDENSER COIL WILL VOID
COMPRESSOR WARRANTY.
It is very important that the Condenser coil or optional air filter is cleaned twice
per month to insure proper refrigeration performance and to prevent compressor
failure. In some environments, it may be necessary to clean more frequently.
Failure to clean condenser coil will void condenser warranty. This procedure is
for Self-Contained models. The remote condenser coil must also be cleaned at
same intervals.
1. Disconnect power to the unit.
2. On ECSS40 Remove the nose panel and on ECSS60 remove the side panel on
left side of case next to the controls.
Carefully vacuum the front surface of condenser coil. Take care not to bend coil
fins with vacuum cleaner nozzle.
-If equipped with optional air filter remove filter and carefully vacuum the front
surface of condenser coil. Take care not to bend coil fins with vacuum cleaner
nozzle. Wash filter using warm soapy water, rinse, and let dry. Apply a generous
coat of filter coat adhesive to both sides of filter. (Filter coat adhesive is available
through any restaurant supply distributor.) Recommended Super Filter Coat
NOTE: Failure to coat filter with a fresh coat of filter adhesive after
cleaning will prevent filter from working properly. Failure to do so
will allow the condenser coil to plug, which will affect refrigeration
performance and could cause compressor failure.

- 32 -
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.
CAUTION: Before servicing case, turn off power at the main breaker of fuse
box.
Case Does Not Operate
Check for disconnected power supply.
Check for tripped breaker on blown fuse.
Check that the thermostat display is on and that the green indicator light
is lit.
Lights Do Not Operate
Check that power switch & light switch is on.
Check for tripped breaker or blown fuse.
Check that light housing cords are plugged in correctly to sockets in the
tower
Case Temperature Too Warm
Check that the cold air inlet and outlet slots are not blocked.
Check for a blocked or dirty condenser coil.
Check for cold airflow. Lack of adequate cold airflow could indicate a
defective evaporator fan or a blocked evaporator coil. Check that paper or
foreign materials are not blocking evaporator. If the evaporator coil is
blocked due to excessive frost, put into manual defrost. Excessive frost
can buildup overtime if the case is set too cold or if there is excessive
humidity in the store.
Check all the fans in the evaporator compartment and tower are running.
Case Sweating Note: Some interior sweating is normal on this case.
Check room ambient – Case is designed to operate in an environment not
to exceed 75ºF and 55% relative humidity.
Check all the fans in the evaporator compartment and tower are running.
Overflow of Condensate Pan
Check that drain in bottom of tub floor is not plugged.
Check that drain trap to the condensate pan is not plugged
Overflow of Optional Condensate Pump:
Check that drain in bottom of tub floor is not plugged.

Special Service Situations
There are rare occasions when the refrigerant charge must be evacuated from a
case 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) from being released into the
atmosphere.
The release of HFO into the atmosphere is a potential source of global warming.
Note the condensing unit that was supplied with this case has a receiver tank
large enough to hold all the charge you may be able to pump down the system
when service is required.
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.
