Refrigerant Oil Distribution Specifications

REFRIGERANT OIL DISTRIBUTION SPECIFICATIONS
Compressor systems require 240 ml (8 fl oz) of Polyalkylene Glycol (PAG) synthetic refrigerant oil GM P/N 12345923, or equivalent. During component replacement, add new oil quantities to the system as shown.


REFRIGERANT OIL LOSS FROM A LARGE LEAK
If the refrigerant charge is abruptly lost because of a large refrigerant leak, approximately 90 ml (3 fl oz) of refrigerant oil will be carried out of the system suspended in the refrigerant. Any failure that caused an abrupt refrigerant discharge will experience this oil loss. Failures allowing the refrigerant to seep or bleed off over time do not experience this oil loss.

When a component is replaced that caused a large refrigerant leak, add 90 ml (3 fl oz) of new PAG synthetic refrigerant oil GM P/N 12345923, or equivalent, plus the required amount of oil for the particular component as stated above. Add the oil directly to the replaced component if possible. If the oil cannot be easily added to the replaced part, add the oil to the receiver dehydrator.
