Leak test
The compressor must be checked for refrigerant
leaks after it is repaired. The procedure is as
follows.
1. Fit plates to the suction and discharge
connections, and tighten it to the specified
torque.
Specified torque: 20 ~ 24 N·m
{2.0 ~ 2.4 kgf·m, 14 ~ 17 lbf·ft}
2. Using the valve assembly (597017-1120), fill
the compressor with refrigerant through the
suction side, raising the refrigerant pressure
to at least 0.49 MPaG {5 kgf/cm
2
, 71 psig}.
3. Check the compressor for leaks using a leak
detector.
Refrigerant charging
In order to prevent a liquid charge and greatly
increase risks of compressor dammage, do not
shake or turn the refrigerant bottle upside-
down.
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
49~150kPa {0.5~1.5kgf/cm
2
, 7.1~21psig}
.
