| If it is not necessary to clean (rinse) the refrigerant circuit, e.g. after external damage resulting from an accident |
| –
| Drain refrigerant circuit. |
| –
| Remove air conditioner compressor. |
| –
| Remove the compressor oil drain plug. |
Note | The „Denso“ (Nippondenso) compressor has a seal instead of an O-ring on the oil drain plug, which must always be replaced. |
| –
| To facilitate draining the refrigerant oil, turn the compressor by the electromagnetic coupling disc. |
| –
| Unscrew the oil drain plug on the old air conditioner compressor (replace the O-ring), turn the compressor around so that the refrigerant oil can run out and only fill with the same amount that has run out (of the old compressor). |
Note | t
| If, e.g. 70 cm3 has been extracted from the defective compressor and 220 cm3 from the genuine part compressor (a small quantity of refrigerant remains in the compressor), in this case, 70 cm3 of refrigerant oil has been filled into the new compressor (the refrigerant oil can be used that has been extracted from the compressor replaced). |
| t
| Use different types and amounts of refrigerant oil for different air-conditioner compressors → Rep. gr.87. |
| t
| If a larger volume of refrigeration oil was drained from the defective compressor (more than 80 cm3), the remaining oil can also be filled into the evaporator or into the fluid container or drip tray → Rep. gr.87. |
| –
| Assemble, vacuum and charge the refrigerant circuit. |
