Draining Procedure

Important:  Drain and measure as much of the refrigerant oil as possible from the removed compressor.

1. Remove the compressor crankcase oil drain plug and drain the crankcase into a clean, graduated container.
2. Drain the oil from both the suction and discharge ports of the removed compressor into the same container.

   Rotate the compressor shaft to assist in draining the compressor.

   This measurement will be used during installation of the replacement compressor.
