P/N: 1230468
The parts listed below are not part of the sealed refrigeration system and are available
separately.
START CAPACITOR - P/N
CHAMELEON: 1112805
TRADE: 1112805
HV3: 1124549
HVV: 1124549
The start capacitor is used to increase power during the start. This additional power will
help get the compressor running in case there is any back pressure.
STARTING RELAY – INCLUDED IN ASSEMBLY P/N
CHAMELEON: 513506066
TRADE: 513506066
HV3: 513506066
HVV: 513506066
The starting relay is mounted in the terminal box on the outside of the compressor
under the housing. When the compressor first starts up, the starting relay closes and
completes a starting circuit. When the compressor motor reaches operating speed, the
starting relay opens and breaks the starting circuit.
THERMAL OVERLOAD SWITCH – INCLUDED IN ASSEMBLY P/N
CHAMELEON: 513506066
TRADE: 513506066
HV3: 513506066
HVV: 513506066
The thermal overload switch is mounted in the terminal box on the outside of the
compressor under the housing. If the compressor motor gets hot or draws too much
current, the thermal overload opens and breaks the starting and running circuit of the
motor. As the motor cools, the thermal overload closes, allowing the compressor to
restart.
TEMPERATURE SENSOR – P/N
CHAMELEON: 1122924
TRADE: 1122924
HV3: 1122924
HVV: 1122924
The temperature sensor is mounted in the inlet airflow of the evaporator. This monitors
the air temperature and reports it to the electronic controller so that the controller can
operate the refrigeration system via the power box.
