Renewing refrigerant circuit components |
Note
t | The refrigerant must be extracted beforehand, e.g. with the air conditioning service station -VAS 6007A-. |
t | The previously used service stations can still be used ⇒ Volkswagen Workshop Equipment catalogue. |
t | Safety measures when working on an evacuated refrigerant circuit → Chapter. |
t | Only the components marked with an * can be renewed without opening and evacuating the refrigerant circuit. |
t | To prevent the ingress of moisture, all components of the refrigerant circuit which have been opened must be sealed with suitable plugs. |
t | The colour coding of O-rings for R134a refrigerant circuits has been discontinued. Coloured and black O-rings are used. |
t | Moisten threaded connections of refrigerant circuit with polyethylene glycol (PEG) VW part number 294440 before installation. |
t | Under certain conditions, it is no longer necessary to renew the receiver each time the refrigerant circuit is opened → Rep. Gr.00Technical information “Air conditioning systems - with refrigerant R134a VW” Renewing parts. |
