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 up.
The operational frequency of the compressor is MSZ09UN: 64Hz, MSZ12UN: 70Hz in EMERGENCY COOL mode and
58Hz in EMERGENCY HEAT mode.
3. The fan speed of the indoor unit is High.
4. This operation continues for 30minutes.
5. In order to release this operation, press the EMERGENCY OPERATION switch twice or once, or press any button on the
remote controller.
