The self-contained models manufactured before 12/1/19 are shipped from the factory with a completely
operational 134A refrigeration system and require no modifications or adjustments upon installation.
Models produced after 12/1/19 are shipped with 531A. 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.
Remote Models Use pressure gauges to set pressure control

Remote Refrigeration Operation
The remote models manufactured before 12/1/19 are designed to use 134A refrigerant and after 12/1/19 are
designed to use R531a 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 or R531A
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.
