Servicing Station, Connecting For Measuring And Testing

- Work procedure may vary depending on the type of tools selected (the tool-specific operating instructions should therefore be followed).

NOTE: The work procedure is always to be performed as described in the operating instructions for the A/C service station VAS 6007A (or subsequent models).

The charging hoses are to be connected as follows to prevent the ingress of air or moisture into the refrigerant circuit:
- Switch off ignition.
- Connect service station to power supply.
- Remove sealing caps from service connections or connections with valve (see vehicle specific refrigerant circuit).
- Evacuate charging hoses if necessary.

NOTE: Connect filler hose with quick-release couplings to refrigerant circuit service connections.

CAUTION: Never open valves on low or high-pressure side with engine running. Otherwise, the compressor or service station could be destroyed by a "short circuit" between the high and low-pressure sides of the refrigerant circuit if the air conditioning system is switched on.

- Open quick-release couplings on the service connections.
