Pipe Connections
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:
1. Tighten the flare nuts using two wrenches. Pay
attention not to damage the pipes.
2. If the tightening torque is not sufficient, there will
probably be some leakage. With excessive tightening
torque, the flange could be damaged and cause
leakage.
3. It is best to tighten the connection by using a fix
wrench and a torque wrench. Please reference the
“Tightening Torque For Protection Caps And Flange
Connection” table.
Bleeding
The air and humidity inside the refrigerant circuit can
cause the compressor to malfunction. After connecting
the indoor and outdoor units, use a vacuum pump to
bleed out the air and humidity.
