Draining Procedure

  1. Drain the oil from both the suction and discharge ports of the removed compressor into a clean, graduated container. Rotate the compressor shaft to assist in draining the compressor.
  2. Measure and record the amount of oil drained from the removed compressor. This measurement will be used during installation of the replacement compressor.
  3. Inspect the polyalkylene glycol (PAG) oil for the following conditions: The color of the oil is dark brown or black. There is a presence of foreign substances, metal fillings, etc. in the oil. If the receiver-dehydrator is not replaced, damage to A/C compressor will occur.
  4. Properly discard the used refrigerant oil.
