Connecting the Pipes
Screw the flare nuts to the outdoor unit coupling with the same tightening procedures described for the indoor unit.
To avoid leakage, pay attention to the following points:
- Tighten the flare nuts using two wrenches. Pay attention not to damage the pipes.
- If the tightening torque is not sufficient, there will probably be some leakage. With excessive tightening torque there will also be some leakage, as the flange could be damaged.
- The surest system consists in tightening the connection by using a fixed wrench and a torque wrench: in this case, use the table on page 30.
Bleeding
Air and humidity left inside the refrigerant circuit can cause compressor malfunction. After having connected the indoor and outdoor units, bleed the air and humidity from the refrigerant circuit by using a vacuum pump.
Refrigerant Pressure Inspection
The low-pressure range of refrigerant R290 is 0.4-0.6 Mpa, and the high-pressure range is 1.5-2.0Mpa. The low-pressure range of refrigerant R32 is 0.8-1.2Mpa, and the high-pressure range is 3.2-3.7Mpa. This means that the refrigerating system or refrigerant of an air conditioner is abnormal if the low or high-pressure ranges of the detected compressor exceed the normal ranges.
Bleeding
The air and humidity left inside the refrigerant circulation can cause compressor malfunction. After having connected the indoor and outdoor units, bleed the air and humidity from the refrigerant circulation using a vacuum pump.
- Unscrew and remove the caps from the 2 - way and 3-way valves.
- Unscrew and remove the cap from the service port.
- Connect the vacuum pump hose to the service port.
- Operate the vacuum pump for 10-15 minutes until an absolute vacuum of 10 mm Hg has been reached.
- With the vacuum pump still in operation, close the low - pressure knob on the vacuum pump coupling. Stop the vacuum pump.
- Open the 2 - way valve by 1/4 turn and then close it after 10 seconds. Check all the joints for leaks using liquid soap or an electronic leak device.
- Turn the body of the 2-way and 3-way valves. Disconnect the vacuum pump hose.
- Replace and tighten all the caps on the valves.
Operation Test
- Wind insulating covering around the joints of the indoor unit and fix it with insulating tape.
