1-16. COMPRESSOR PREHEATING

When the outdoor heat exchanger temperature is lower than - 4°C (5°C:JM2 Open) and the all operation
has been stopped for 30 minutes, power is applied to the compressor and the compressor is heated.
(By heating the compressor, warm air is quickly discharged when operation is started.)
When operation was started, and when the heat exchanger temperature rises up, preheating is ended.
