A/C Compressor Installation Note

CAUTION:
  • Due to the high moisture-absorption characteristics of the compressor oil, it may absorb moisture if left over a long period of time thereby negatively affecting A/C operation. Drain the compressor oil and refill within 10 min. of each other.
  1. Rotate new A/C compressor shaft six to eight revolutions while draining new refrigerant oil in a clean measuring device. Use this refrigerant oil to refill new compressor. Do not allow refrigerant oil to become contaminated.
  2. Rotate old A/C compressor shaft six to eight revolutions while draining old refrigerant oil in a separate, clean measuring device.
  3. Compare those oil amounts. The amount of the oil drained from the new A/C compressor should be greater than the old one.
  4. Pour the same amount oil of drained from the old A/C compressor back into the new A/C compressor.
