and nitrogen (e.g. in the event of external
damage following an accident)
- Discharge refrigerant circuit.
- Remove A/C compressor.
- Remove oil drain plug from compressor.

- The oil drain plug of "Denso" (Nippondenso) compressors
is equipped with an oil seal instead of an O-ring and this is
always to be replaced.

- To accelerate drainage of refrigerant oil, rotate
compressor e.g. by way of clutch plate of A/C clutch for
example.
- Pour old refrigerant oil out of compressor (observe
disposal HSO Environment Vol. 2-2. 43. 1 ).
- Remove oil drain plug from replacement compressor,
pour out refrigerant oil and only add a quantity of fresh
refrigerant oil equal to the amount poured out of the
malfunctioning compressor.
Note:
- If, for example, 70 cm 3 of refrigerant oil has been poured
out of the malfunctioning compressor and 220 cm 3 out of
the replacement compressor (a small quantity of refrigerant
oil remains in the compressor). Fill the compressor to be
installed with 70 cm 3 of refrigerant oil (use can be made of
oil poured out of replacement compressor).
- Use different refrigerant oils and quantities for the various
compressors

Group 87 ,
- If a greater quantity of refrigerant oil (more than approx.
80 cm 3 ) has been poured out of the malfunctioning
compressor, the remaining refrigerant oil can also be
added to the evaporator or reservoir/receiver
