2. Above data is for heating operation without any frost.

How to operate with fixed operational frequency of the compressor.

1.Press the EMERGENCY OPERATION switch on the front of the indoor unit, and select either EMERGENCY COOL mode or EMERGENCY HEAT mode before starting to operate the air conditioner.

2.The compressor starts with operational frequency.

3.The fan speed of the indoor unit is High.

4.This operation continues for 30 minutes.

5.In order to release this operation, press the EMERGENCY OPERATION switch twice or once, or press any button on the remote controller.
