Part 4 Trouble Shooting

Trouble 3

The Compressor/Outdoor Fan does not operate (9, 12kBtu/h Model)

Turn on the main power.

Using the remote controller, set the indoor set point to at least 15˚C(5˚F) less than the indoor air temperature.

When in air circulation mode, compressor/outdoor fan is stopped.

Check that the sensor for Indoor temperature sensor is attatched and as close to the heat exchanger (EVA.) as possible.

When displaying Error code, refer to the trouble shooting guide.

Check the main power source.(AC 208V~230V)

Check the trouble shooting guide error code 6,9

Turn off main power.

Check the electrical wiring diagram of Outdoor side.

Check the open or short of connecting wires between Indoor and Outdoor.
