J 9625-A Pressure Testing Connector

1. Install the J 9625-A (1) to the suction/discharge ports on the compressor.
2. 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.
3. Connect the charging station high-pressure and low-pressure lines to the corresponding fittings on the J 9625-A , 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.
4. 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.
5. 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.
6. If an external leak is present, perform the necessary corrective measures and recheck for leaks to verify that the leak has been corrected.
7. 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 valve depressor-type hoses are used, loosen the hose connections at the gage manifold to release vapor pressure from the compressor.
8. Disconnect both gage hoses. Remove the J 9625-A .
