| Cleaning refrigerant circuit |
| The refrigerant circuit must be flushed out with refrigerant R134a → Chapter (or blown out with compressed air and nitrogen → Chapter) in the following cases: |
| –
| If moisture or dirt has entered the refrigerant circuit (e.g. following an accident) |
| –
| If the refrigerant oil is dark and viscous |
| –
| If there is too much refrigerant oil in the refrigerant circuit after renewing compressor |
| –
| If the air conditioner compressor has to be renewed due to „internal“ damage (e.g. noise or no output) |
Note | When blowing out components with compressed air and nitrogen, always extract the gas mixture escaping from the components with suitable extraction units (workshop extraction system). |
