AIR PURGING Air purging Air and moisture in the refrigerant system have undesirable effects as indicated below: Pressure in the system rises. Operating current rises. Cooling or heating efficiency drops. Moisture in the refrigerant circuit may freeze and block capillary tubing. Water may lead to corrosion of parts in the refrigeration system.
Page 22
AIR PURGING When relocate the unit to another place, perform evacuation using vacuum pump. Make sure the refrigerant added into the air conditioner is in liquid form in any case. (Not applicable to units that use freon R22 ) Caution in handling the packed valve Open the valve stem until it hits against the stopper.
TEST RUNNING Safety and leakage check Electrical safety check Perform the electric safe check after completing installation: 1. Grounding work After finishing grounding work, measure the grounding resistance by visual detection and grounding resistance tester. 2. Electrical leakage check (performing during test running) During test operation after finishing installation, the service person can use the electroprobe and multimeter to perform the electrical leakage check.

Rated Capacity Test (Cooling mode) Under Cooling Mode, set the air conditioner at High Fan Speed and set the temperature to 17 C, then press the TURBO button 6 times within 10 seconds (be sure the indoor unit buzzes 6 times). The system will enter Rated Capacity Test mode.
