| Extractor, filler and measurement valves for quick couplings of the service position on the refrigerant circuit |
WARNING | Before removing the extractor and filler valves, the refrigerant must be drained off with the aid of the A/C service station. |
| If the refrigerant circuit is not opened within 10 minutes after draining it off, pressure can arise in the refrigerant circuit due to the post-evaporation. Drain the refrigerant once again. |
|
| l
| Only use valves and connections that are resistant to refrigerant R134a and related refrigerant oils. |
| l
| Different connections (outside diameter) for the high-pressure and low-pressure side guarantee that the quick-coupling adapters are not interchanged. |
| l
| After disconnecting the quick-coupling adapter tighten the caps to prevent any dirt from penetrating. |
| Special tools and workshop equipment required |
