| Without needing to purge refrigerant circuit of contaminants (cleaning), e.g. in cases of external damage after an accident |
| –
| Drain refrigerant circuit. |
| –
| Remove air conditioner compressor. |
| –
| Remove oil drain screw from air conditioner compressor. |
| –
| To speed up the draining of the refrigerant oil, rotate the shaft of the air conditioner compressor using the magnetic clutch poly V-belt pulley. |
| –
| Remove oil drain screw from genuine air conditioner compressor, pour out refrigerant oil and replace it with only the quantity of fresh refrigerant oil equal to the amount of refrigerant oil poured out of the defective air conditioner compressor. |
Note | t
| If for instance 70 cm3 refrigerant oil was poured out of the defective air conditioner compressor, and 220 cm3 oil was poured out of the genuine air conditioner compressor (a small quantity of refrigerant oil remains in the air conditioner compressor), Pour 70 cm3 refrigerant oil into the genuine air conditioner compressor (the refrigerant oil previously poured out of the genuine air conditioner compressor part may be used). |
| t
| Different air conditioner compressors require different types and quantities of refrigerant oils → Rep. gr.87. |
| t
| If a large quantity of refrigerant oil (more than about 80 cm3) was poured from the defective air conditioner compressor, the remaining refrigerant oil can also be poured into the evaporator or the reservoir or receiver → Rep. gr.87. |
| –
| Assemble refrigerant circuit, evacuate and charge. |
