Earth leakage circuit breaker

Power supply for cord heater

* Be sure to connect the fuse and the thermostat to LIVE side of the cord heater.

3. Cord heater installation wiring diagram

NOTE:

Separate the cord heater power from the air conditioner power, and connect it to its exclusive breaker.
By doing so, the power consumption can be decreased because the breaker can be turned off if there is no

possibility of freezing of the base plate in cooling operation, etc.
When the cord heater power is connected to the inverter P.C. board assembly or others without connected to

the exclusive breaker, the control P.C. board of the inverter assembly may cause a failure.
When the cord heater has been mounted on a base plate, do not mount the water-proof cap and drain nipple

which are provided with the outdoor unit on the base plate.
