OPERATION
The system temperature is controlled by the pressure control which is located inside the
compressor housing. The TXV metering device controls the flow of refrigerant to the evaporator
of the unit.
The low pressure control (physically located in the front of the compressor compartment) is
used to cycle off the compressor. The low pressure control should not be adjusted from the
factory settings. Adjustment of this control may cause performance problems with the unit.
