Refrigerant Oil: Service and Repair
Compressor Oil - Topping Up and Adjusting For R12
CAUTION: R12 systems use mineral oil.
-
Too much oil gives poor cooling. Too little oil damages the compressor. When repairing leaks, or changing any components, the compressor oil
must be topped up. The quantity of oil for each component depends on whether the leakage was slow or quick. Use mineral oil for the R12 system.
-
The A/C system is filled with 135 ml of compressor oil. A certain amount of compressor oil is always lost when draining refrigerant and replacing
components. This amount must be recharged so that the operation of the system will not be adversely affected.
-
Compressor oil should be topped up through the compressor oil plug.
-
The table shows how much compressor oil is lost in connection with various types of work on the A/C system.
CAUTION: The new compressor is filled with 135 ml of oil before delivery. In order not to have too much oil in the A/C system, and so
impaired cooling, oil must be drained from the compressor before it is fitted. How much will depend on the amount of oil that has been lost in
connection with the replacement of other components, if any. The A/C system should always contain 135 ml of compressor oil.
-
If only the compressor is being changed, 75 ml of oil should be drained from the new compressor (135 - 60 = 75). If, for example, the desiccant
container is also being changed, only 20 ml of oil should be drained from the compressor, as per the example in table above.
