Air conditioning service station -VAS 6007A- (and further service stations currently available)

→ Workshop equipment

The procedures for testing, extracting (recycling), evacuating and charging should be carried out in accordance with the respective user's manual. The installed filter and dryer must be renewed at the latest at the end of the period of use specified in the operating instructions and every time that the station is emptied (keep replacement filter on hand. they can be ordered from the manufacturer of the device, see user's manual. Air conditioner service stations or purging devices approved by VW but not shown here may also be used.

→ Workshop equipment

Note This air conditioner service station incorporates the following common individual devices: charging cylinder, manifold gauge, vacuum pump, shut-off valves and charging hoses. This air conditioner service station includes one of each type of quick-release coupling (for high-pressure and low-pressure side service connections).

Purging device for refrigerant circuits -VAS 6337/1- from “Behr” or later model. Note

With filter -1- and two large cylindrical sight glasses

The filter in the purging device for refrigerant circuits should be changed after about 2 purging cycles (depending on the level of contamination from the purged refrigerant circuits). If a heavily contaminated refrigerant circuit is purged (the refrigerant oil from the refrigerant circuit is black and viscous or there are large amounts of shavings in the refrigerant circuit) renew filter after purging refrigerant circuit.

Purging device for refrigerant circuits -VAS 6336/1- from “Waeco” or later model. Note

With filter -1- and one sight glass

The filter in the purging device for refrigerant circuits should be changed after about 2 purging cycles (depending on the level of contamination from the purged refrigerant circuits). If a heavily contaminated refrigerant circuit is purged (the refrigerant oil from the refrigerant circuit is black and viscous or there are large amounts of shavings in the refrigerant circuit) renew filter after purging refrigerant circuit.
