Case Refrigeration
Operation
Each self‐contained model is equipped with its own condensing unit located beneath the display area. The unit will be
charged per nameplate refrigerant and shipped from the factory with all service valves open, completely ready for opera‐
tion when electrical power has been connected.
The self‐contained refrigeration system is thermostatically regulated. The thermostat in the case is set to a certain cut
out point in which the case will refrigerate until that cut out point is reached and will cease to refrigerate the case by the
thermostat.

Condensate Pan Setup
Setup:
There is one condensate evaporator pan on this unit for self-contained models. The drain pipe from the case feed into the
condensate pan, once water levels are high enough in the condensate pan the float switch level is triggered which will then
trigger the heater to raise temperature therefore evaporating the water into the case airstream.
