The self-contained models are shipped from the factory with a completely operational 134A 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.
Self Contained Refrigeration Operation
The unit temperature is controlled by an electronic control that senses air temperature and turns
refrigeration on off as required to maintain proper temperature.
The electronic control will also sense a frosted coil that requires a shutdown defrost cycle and shuts down
refrigeration until defrost is complete. There are may also a defined number of daily defrosts that will also
shut the refrigeration solenoid to insure a full defrost occurs. The solenoid will remain off until the either
the off time is reached or until the electronic control senses low temperature set point

Remote Refrigeration Operation
The remote models are designed to use134A 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 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 off until the either the off time is reached or until the
electronic control senses that low temperature set point has been reached.
The electronic control will also sense a frosted coil that requires a shutdown defrost cycle and closes
solenoid until defrost is complete. There are may also a defined number of daily defrosts that will also shut
the refrigeration solenoid to insure a full defrost occurs. The solenoid will remain off until the either the off
time is reached or until the electronic control senses low temperature set point.

Remote Refrigeration Instruction
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 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 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.

The standard Self Contained case is furnished with an electric condensate evaporator. Plumbing
connections are not required.
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.
NOTICE: During normal defrost cycles, steam from the condensate
Condensate Pump (Standard Remote, optional Self Contained)
NOTICE: This unit could be shipped with an optional condensate pump. The pump has a
float that turns the pump on automatically when needed.
The pump is mounted in the base compartment. The pump should be cleaned and
inspected every 3-4 months.
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 verticle 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.

ITR Refrigerated Remote Models
Cabinet Preparation
The ITR Remote models have a large condensate evaporator compartment hanging from the bottom of case
that contains the condensate evaporator pan. This compartment hangs inside the cabinet compartment. The
interior of the cabinet must be open to allow space for this compartment. The countertop must be cut to
allow the case’s base and condenser compartment to drop into the cabinet interior. Use the diagram below
for cutout dimensions.
Once the case is placed into cutout it must be secured to cabinet using brackets and wood screws provided.
IMPORTANT: When placing cases in a line up the number of end panels used will be different. The cut
out and hole placement dimension will need to be adjusted for each particular line up circumstance. See
LINE UP INTALLATION section of this manual.
The condensate air louvers are located on each side of the condensate evaporator compartment. Do not
block these louvers. The louver panel provided with case must be installed in the cabinet to allow
condensate moisture to vent. The louver can be placed on any side of cabinet, but must be as near to the top
as possible. A 6” minimum clearance must be maintained from cabinet louver.
Connect remote refrigeration lines
1. Remove the cover by removing the (4) screws on the bottom of case inside the cabinet
compartment.
1. Connect remote refrigeration as described in the Remote Connection section in this manual. A 2-3/4
hole through the condensate evaporator compartment is provided.
2. Make sure that the drain line has not been dislodged during shipment and that the drain trap is
located properly over the water reservoir of the condensate evaporator pan.
3. Reinstall evaporator condensate cover.

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. Allow refrigerated models to run for at
least two hours before placing pre chilled product into unit
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.
-CASE SHOULD BE STOCKED WITH PRE-CHILLED PRODUCT
ONLY.

ELECTRONIC CONTROL OPERATION
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 on the
centerline of the display case 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 38°F (3.3°C). The Temp control cuts out at 24°F (-4.4°C)
at the coldest setting (“9”) and 32°F (0.0°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 18°F (-7.8°C)
for 5 minutes into the refrigeration cycle (e.g. if the air stream probe measures 32°F/0°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
approx. five seconds. This is typically unnecessary and should only be performed if special
circumstances require it.

-Check that power switch is on.
Lights Do Not Operate
-Check that light switch is on.
-Be sure light cord is properly seated into LED light strip.
-Is the light cord plugged in to light strip upside down.
- Be sure that the rear doors are closed and tightly sealed.
-Check for a blocked or dirty condenser coil fins.
-Is the case installed properly to allow adequate air flow to and from condenser?
Case Temperature Too Warm
-Check that the cold air inlet and outlet slots are not blocked.
-Check cold airflow. Lack of adequate cold airflow could be a defective evaporator fan or
blocked evaporator coil. Check that paper or foreign material is not blocking evaporator.
If the evaporator coil is blocked due to excessive frost, turn the power switch “off” position
for approximately one hour to defrost.
-Check that the electronic control settings are correct.
-Check environment conditions. This case is designed to operate in no more than 80 degree
55 percent humidity.
