Compressor Oil: Adjustment

If a component has been replaced, add an appropriate amount of compressor oil (same as the amount of remaining oil in removed component).
When replacing the compressor, the new compressor will already have the specified amount of oil in it. Adjust the oil amount (so that the amount remains the same as that of the removed compressor) and install the new compressor.

NOTE: Since the hygroscopicity of compressor oil is high, perform this series of works quickly.
