Air purging
Air containing moisture remaining in the refrigerant cycle may cause a malfunction of the compressor. After connecting
the indoor and outdoor units, evacuate air and moisture from refrigerant cycle using a vacuum pump, as shown below.
Note:
Because the system pressure is high and also to protect the environment, be sure not to discharge the
refrigerant to the air directly.
