Tools Required
J 9625-A Pressure Test Set
- Install the J 9625-A
(1)
connector to the suction/discharge ports on the compressor.
- Attach the center hose of the manifold gage set on the charging station
to a refrigerant drum standing in an upright position. Open the valve on the drum.
- Connect the charging station high and low-pressure lines to the corresponding
fittings on the J 9625-A
(1)
connectors, or hoses equipped with valve depressors. The suction port, low-side, of
the compressor has a large internal opening. The discharge port, high-side, has a
smaller internal opening into the compressor.
- Open the low-pressure control, the high-pressure control, and the refrigerant
control on the charging station to allow the refrigerant vapor to flow into the compressor.
- Using a leak detector, check for leaks at the high-pressure relief valve
seal, the housing seal, the rear head seal, the center cylinder seal, the through-bolt
gaskets, and the compressor shaft seal. After checking for leaks, shut off the low-pressure
control, the high-pressure control, and the refrigerant control lines on the charging
station.
- If an external leak is present, perform the necessary corrective measures
and recheck for leaks to verify that the leak has been corrected.
- Loosen the manifold gage hose connections to the gage adapters connected
to the low and high sides. Allow the vapor pressure to release from the compressor.
If the valve depressor-type hoses are used, loosen the hose connections at the gage
manifold to release vapor pressure from the compressor.
- Disconnect both gage hoses. Remove the J 9625-A
(1).
