  2. 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.
  3. 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

 

mceclip39.png

 

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

 

mceclip40.png

 

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.

 

mceclip41.png
