| Removing contaminants from the refrigerant circuit |
| Flush the refrigerant circuit with R134a (if necessary blow through), if: |
| –
| Humidity or dirt has penetrated into the refrigerant circuit (e.g. after an accident). |
| –
| The refrigerant has become dark and thick. |
| –
| After a compressor replacement there is too much refrigerant oil in the refrigerant circuit. |
| –
| The air conditioning compressor must be replaced because of internal damage (e.g. it is too laud, jammed or no output). |
