Leak test
The compressor must be checked for refrigerant
leaks after it is repaired. The procedure is as
follows.
1. Fit the connectors to the suction and discharge
connections, and tighten it to the specified
torque.
Specified torque:
25 - 32 N·m
{2.5 - 3.3 kgf·m, 18 - 24 lbf·ft}
2. Fill the compressor with refrigerant through the
suction side, raising the refrigerant pressure to
at least 0.39 MPaG {5 kgf/cm2, 56.3 psig}.
3. Check the compressor for leaks using a leak
detector.
Storing a repaired compressor
If it is necessary to store a repaired compressor
for some time before installation, evacuate the
compressor and fill it with dry nitrogen gas through
the suction fitting to raise the pressure to 30 ~ 100
kPa {0.3 - 1.0 kgf/cm2, 4.4 - 14.5 psi}.
