A/C System, Operating After Charging

A/C System, Operating After Charging

NOTE: If A/C compressor was removed, it must be cranked by hand at ribbed belt pulley/freewheel approximately 10 rotations before bringing into operation for the first time. This prevents damage caused by liquid impact in the A/C compressor when first switching on the A/C system (any oil in compressor cylinder is forced out on rotation).







- Start engine with compressor switched off (version with A/C clutch).
- Set compressor to minimum output, i.e. "Econ" or A/C off mode (version with no A/C clutch with regulating valve).
- Wait until idle speed has stabilized.
- Switch on compressor and operate system for at least 2 minutes at idling speed.
- If necessary, check pressures in refrigerant circuit using A/C service station.
- Turn engine off.
- Screw out hand wheel on quick-release coupling adapter.
- Disconnect charging hoses from refrigerant circuit.
- Screw protective caps back on.
