OUTDOOR LOW PRESSURE AND OUTDOOR UNIT CURRENT
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 G09: 79Hz, G12: 85Hz 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.
NOTE : The unit of pressure has been changed to MPa on the international system of units(SI unit system).
The conversion factor is: 1(MPa [Gauge])
