Page 16: Air Purging Of The Piping And Indoor Unit
Caution: Capacity is base on standard length and maximum allowance length is base of reliability. Oil trap should be installed per 5-7 meters. 6.4 Air purging of the piping and indoor unit Required tools: Hexagonal wrench; adjustable wrench; torque wrenches, wrench to hold the joints and gas leak detector. Note: The air in the indoor unit and in the piping must be purged. - Page 17 tightened further, continue working from step (4). If the gas leaks do not stop when the connections are retightened, repair the location of the leak, discharge all of the gas through the service port, and then recharge with the specified amount of gas from a gas cylinder.

6.7 Balance refrigerant of the 2-way, 3-way valves Procedure: 1. Confirm that both the 2-way and 3-way valves are set to the open position. 2. Connect the charge set to the 3-way valve’s service port. Leave the valve on the charge set closed. Connect the charge hose with the push pin to the service port. -
Page 21: Evacuation
6.8 Evacuation Procedure: 1. Connect the vacuum pump to the charge set’s centre hose. 2. Evacuation for approximately one hour. Confirm that the gauge needle has moved toward -0.1 Mpa (-76 cmHg) [vacuum of 4 mmHg or less]. 3. Close the valve (Low side) on the charge set, turn off the vacuum pump, and confirm that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump). -
Page 22: Gas Charging
6.9 Gas charging Procedure: 1. Connect the charge hose to the charging cylinder. Connect the charge hose which you disconnected from the vacuum pump to the valve at the bottom of the cylinder. 2. Purge the air from the charge hose. Open the valve at the bottom of the cylinder and press the check valve on the charge set to purge the air (be careful of the liquid refrigerant). -
