Air Conditioner, Starting After Charging

Air Conditioner, Starting After Charging

NOTE: If the compressor has been removed, rotate it about 10 times by hand prior to initial start-up to prevent damage caused by liquid impact when first switched on (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 regulator valve).
- Wait until idling 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.
- Switch off engine.
- Screw out handwheel on quick-release coupling adapter.
- Disconnect charging hoses from refrigerant circuit.
- Screw protective caps back on.
