Refrigerant Oil: Service and Repair
NOTE:
^
The new compressor is filled with 200 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 200 ml of compressor oil.
^
If a new compressor only is to be fitted, drain 110 ml of oil from it (200-70-20 = 110). For example, if you also install a new receiver, only 70 ml
should be drained from the compressor, as shown in the table above.
Filling And Adjustments Of Compressor Oil
The A/C system is filled with 200 ml of compressor oil. A certain amount of compressor oil is always lost in connection with the draining of
refrigerant and replacement of components. This amount must be filled up again so that the operation of the system will not be adversely affected.
Filling of compressor oil should be carried out on the compressors high-pressure side. Compressor oil is supplied in tubes of 20 ml.
The table above shows how much compressor oil is lost in connection with various types of work on the A/C system.
