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.

Rotate new A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a clean measuring device. Use this refrigerant oil to refill new compressor. Do not allow refrigerant oil to become contaminated.
Rotate old A/C compressor shaft six to eight revolutions while collecting refrigerant oil in a separate, clean measuring device.
Compare those oil amounts. The amount of the oil drained from the new A/C compressor should be greater than the old one.
Pour the same amount oil of drained from the old A/C compressor back into the new A/C compressor.
