4-4. Fan Motor
The fan motor is a single phase, induction type
motor which drives fans on the evaporator side
and the condenser side at the same time.
Specifications:
Rated Voltage AC 230V
Rated Output 552 Watts
UL Listed File No. E49807
4-5. Compressor Motor
The compressor motor is a single phase motor
and is contained within the same housing as the
compressor.
Specifications:
Rated Voltage AC 230V
Rated Output 1600 Watts
NOTE
An internal overload relay is used to protect the
compressor motor and fan motor. This relay is
built into the compressor motor and fan motor and
will interrupt the flow of current when there is an
overcurrent situation or if abnormally high
temperature builds up in the compressor motor or
fan motor.
4-6. Anti-freezing Thermostat
If the evaporator has frosted, the thermostat
contacts open to stop the compressor and the
unit continues to operate on “FAN” mode. Once
the evaporator has defrosted, the contacts close
to restart the compressor and the unit operates
in “COOL” mode. The thermostat heat sensing
tube is mounted at the evaporator outlet tube
and is insulated from surrounding air by heat
insulating material. The thermostat contacts are
opened at -1.5˚C and closed at +14.5˚C.
