Important: Drain and measure as much of the refrigerant oil as possible from the removed compressor.
Rotate the compressor shaft to assist in draining the compressor.
This measurement will be used during installation of the replacement compressor.
Important: During the oil removal procedure, the condition of the oil should be evaluated. Compressor oil never breaks down unless something is wrong with the compressor or air conditioning (A/C) system. If one or more of the following conditions exist, replace the compressor and receiver dehydrator.
Important: The refrigerant oil in the A/C system must be balanced during compressor replacement.
• | Less than 120 ml (4.0 oz), leave the 120 ml (4.0 oz) in the replacement compressor. |
• | More than 120 ml (4.0 oz), add to the compressor the difference between the 120 ml (4.0 oz) and the amount drained. |
