Work procedures: The operations "testing, extraction (recycling), evacuation and charging" are to be performed in line with the relevant operating instructions.

The filters and dryers installed are to be replaced at the latest at the end of the period of use specified in the operating instructions and whenever the station has been drained (keep replacement filter to hand. available from equipment manufacturer. Refer to operating instructions).

Other A/C service stations or flushing equipment that is approved by VW but not illustrated here may also be used.

Refer to the Workshop Equipment Catalog.

Note

The following known units are assembled in this A/C service station: Charging cylinder, pressure gauge set, vacuum pump, shutoff valves and charging hoses.

One quick-release coupling each (for service connections on high and low-pressure side) is included in the scope of delivery of this A/C service station.

Commercially Available Tools and Materials

Air Conditioning Flush Tool -VAS6337/1A- from the company “Behr” or succeeding model

Note

With a filter -1- and two large cylindrical viewing glasses.

The filter in the refrigerant circuit flushing device depends on the type and degree of contamination in the flushed refrigerant circuit, it should be changed after 2 flushing cycles at the latest. If a heavily contaminated refrigerant circuit is flushed (the refrigerant oil from the circuit is black and viscous or there are many shavings in the refrigerant circuit), the filter should be replaced after flushing.
