Draining Procedure
- Remove the compressor crankcase oil drain plug and drain the crankcase (1) into a clean, graduated container.
NOTE: Drain and measure as much of the refrigerant oil as possible from the removed compressor.
- 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.
- Measure and record the amount of oil drained from the removed compressor. This measurement will be used during installation of the replacement compressor.
- Inspect oil drained from removed compressor. Refer to Air Conditioning Compressor Oil Diagnosis
- Properly discard the used refrigerant oil.
