2.4.1 A/C System, Operating after Charging
Note
If the 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 oil in compressor cylin‐
der is forced out on rotation).
