Draining Procedure

  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.
  3. Measure and record the amount of oil drained from the removed compressor. This measurement will be used during installation of the replacement compressor.
  4. Properly discard the used refrigerant oil.
