Refrigerant Circuit, Discharging Using Service Station



Refrigerant Circuit, Discharging Using Service Station

- Work procedure may vary depending on the type of tools selected (the tool-specific operating instructions should therefore be followed).
- The refrigerant circuit is to be discharged if parts of the refrigerant circuit are to be removed, if there is any doubt about the quantity of refrigerant in the circuit or if safety precautions so require.
- All the necessary usage information for working with the refrigerant service station can be found in the service station operating instructions.

Draining:
- Switch off ignition.
- Connect service station in line with operating instructions to vehicle service connections and start up service station.

NOTE:
- There is a possibility of refrigerant oil being extracted from the refrigerant circuit together with the refrigerant. To ensure compressor lubrication, the refrigerant oil in the circuit must be topped up with fresh oil.
- On vehicles equipped with a compressor with no A/C clutch (with A/C Compressor Regulator Valve N280) the engine should not be run for longer than absolutely necessary with the refrigerant circuit empty (compressor always in operation as well).
- On vehicles with a compressor with A/C clutch, the engine is only to be started following complete assembly of the refrigerant circuit.
