A/C System, Operating After Charging: Notes

If the mechanically driven A/C compressor has been removed, rotate it about 10 times by hand prior to initial start-up (when or after installing, for example prior to installing the ribbed belt) to prevent damage caused by liquid impact when first switched on (any refrigerant oil in compressor cylinder is forced out on rotation). Refer to A/C COMPRESSOR, REMOVING AND INSTALLING .

If the electronically driven A/C compressor was removed, activate it after filling the A/C compressor before the A/C system on via the "basic setting, compressor cut-in" function for the Guided Fault Finding. Use the Vehicle Diagnostic Tester in the "Guided Fault Finding" function for A/C System and battery regulation. This prevents the A/C compressor from becoming damaged for example by liquid impact when it is first switched on (any refrigerant oil in the A/C compression chamber is forced out).

The vehicle engine drives the mechanically driven A/C compressor via a belt or shaft. The electrically-driven A/C compressor is driven via an electric motor directly on the A/C compressor. Refer to A/C COMPRESSOR, REMOVING AND INSTALLING .
