Connecting the A/C service station to the refrigerant circuit for measuring and testing
  Note
t  Depending on the type of the selected A/C service station, variations can occur in the work procedure.
t  The work procedure must always be carried out as described in the operating instructions of the selected A/C service station.
So that neither air nor humidity can pass through the filling hoses into the refrigerant circuit, they must be connected according to the following work procedure:
–  Switch off ignition.
–  Connect the A/C service station to the voltage supply.
–  Unscrew the screw caps from the service connections or the connections with valve, see refrigerant circuit specifically designed for vehicles → Heating, Air Conditioning → Rep. gr.87.
–  If necessary, evacuate the filling hoses.
–  Connect the filling hoses of the A/C service station with quick couplings to the service connections of the refrigerant circuit.
  WARNING
Do not open the valves on the low or high pressure side with the engine running. Otherwise, the compressor or the A/C service station can be destroyed due to the short-circuit between the high and low pressure side of the refrigerant circuit, when the air conditioning system is switched on.
–  Screw in the handwheel of the quick-coupling adapters so far until the valves of the service connections are safely opened (observe the pressure gauge, do not over-press the valve).
