| Remove the oil drain plug -B- / -D- from the air conditioner compressor -A-.* |
Note t
| The design of the oil drain plug -B- / -D- and the seal -C- / -E- varies (depending on the air conditioner compressor manufacturer). |
t
| On the „Denso“ or „Nippondenso“ air conditioner compressor, the oil drain plug -D- is fitted with a sealing ring -E- for example; always renew → Electronic parts catalogue. |
t
| On the „Sanden“ or „Zexel“ air conditioner compressor, the oil drain plug -B- is fitted with an O-ring -C- for example; always renew → Electronic parts catalogue. |
t
| To accelerate drainage of the refrigerant oil, crank the air conditioner compressor by way of the magnetic clutch plate for example. |
Note t
| Then fill the air conditioner compressor with the quantity of fresh refrigerant oil corresponding to the quantity of refrigerant oil in the replacement compressor → Chapter.* |
t
| Use different refrigerant oils and quantities for the various air conditioner compressors → Chapter. |
t
| To ensure air conditioner compressor lubrication on start-up, at least 80 cm3 of refrigerant oil must be poured into the air conditioner compressor. The remainder can be added for example to the new reservoir or receiver → Chapter. |
t
| If dirt has ingressed into the air conditioner compressor with the refrigerant circuit open (e.g. after an accident), the air conditioner compressor is to be renewed. |
t
| Clean refrigerant circuit (flush with refrigerant R134a → Chapter or blow out with compressed air or nitrogen → Chapter).* |
