Service Station, Connecting For Measurement and Testing

Service Station, Connecting For Measurement 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 r A/C service station VAS 6007A.

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

NOTE: Connect quick-release couplings to service connections of refrigerant circuit.

CAUTION:
- A/C compressor or service station may be damaged if quick-release couplings are opened.
- A "short circuit" may occur between high and low-pressure sides of refrigerant circuit if engine is running and quickrelease couplings have been opened.
- Engine must not be running or quick-release couplings at service connections must be closed.

- Open quick-release couplings at service connections.
