Air purging

Air and moisture in the refrigeration system have undesirable effects as indicated
below:

1. Pressure in the system rises.

2. Operating current rises.

3. Cooling or heating(only for

models with heating function)
efficiency drops.

4. Moisture in the refrigerant circuit
may freeze and block capillary
tubing.

5. Water may lead to corrosion of
parts in the refrigeration system.

Therefore, the indoor unit and tubing
between the indoor and outdoor unit
must apply leakage test and be evacuated
to remove any noncondensables and
moisture from the system.
