Description Function Basic Operations
Compressor Hermetically Sealed
Compressor
Compresses the refrigerant. Enabled when beverage is
dispensed and the cabinet
needs to be cooled.
Condenser Lanced Fin Condenser Cooling of compressed
refrigerant.
Enabled when beverage is
dispensed and the cabinet
needs to be cooled.
Fan-
Condenser
Fan Provides air flow to remove
heat from the condenser.
Enabled when beverage is
dispensed and the cabinet
needs to be cooled.
AXV Automatic Expansion Valve Controls refrigerant flow
during water cooling.
Filter Dryers Keeps moisture, dirt, and
metal from entering the valves
or the cap tube.
EPR Valve Evaporator Pressure
Regulator
Limits the minimum refrigerant
pressure in the cabinet.
Limits the minimum refrigerant
pressure so the cabinet
doesn't freeze.
SV01 Chiller Liquid Solenoid Controls the flow of refrigerant
to the AXV valve.
SV02 Cabinet Liquid Solenoid Controls the flow of refrigerant
to the cabinet.
SV03 Suction Solenoid Stops the flow of refrigerant
back to the chiller when the
cabinet is cooling.
LIV Liquid Injection Valve Controls the injection of liquid
refrigerant into the suction
line.
Liquid refrigerant is injected
into the suction line to lower
the discharge temperature of
the compressor.
