REFRIGERATION
Self Contained Models Use pressure gauges to set pressure control.

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 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 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.
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 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.
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
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.
