A/C System, Starting After Charging Refrigerant Circuit
There is a risk of damaging the A/C compressor. Refrigerant oil may accumulate in the compression chamber when the A/C compressor is removed.
- After installing a new A/C compressor or filling with fresh refrigerant oil, turn the A/C compressor 10 times by hand before installing the ribbed belt.
-- Start the engine with the A/C compressor switched off (version with A/C clutch).
-- Set the A/C compressor to minimum output, such as "ECON" mode or A/C off (version with no A/C clutch with regulator valve).
-- Wait until idle speed has stabilized.
-- Switch on the A/C compressor and operate the system for at least two minutes at idle speed.
Risk of damaging the A/C compressor or the A/C service station.
A short circuit between the high and low pressure side is possible when opening the valves with the A/C system is on.
- Never open the valves in the high or low pressure side when the A/C system is on.
-- If necessary, check the pressures in the refrigerant circuit using the A/C Service Station.
-- Turn off the engine.
-- Unscrew the hand wheel at the quick-release coupling adapter.
-- Disconnect the charging hose from the refrigerant circuit.
-- Screw the protective caps back on.
