Starting up air conditioner after charging |
Note t
| If it has been removed, give the mechanically driven air conditioner compressor approx. 10 turns by hand prior to initial start-up (on or after installation, e.g. before fitting the belt) to prevent damage caused by fluid lock when first switched on (any oil in the air conditioner compressor cylinder is forced out by the cranking action). |
t
| If it has been removed, the electrically driven air conditioner compressor is to be started up, prior to initial commissioning of the air conditioner and following charging, by way of the „Basic setting, compressor run-in“ function of the Guided Fault Finding routine → Vehicle diagnostic tester, „Guided Fault Finding“ function for air conditioner and battery regulation. This guards the air conditioner compressor against damage caused for example by fluid lock when first switched on (any oil in the combustion chamber of the air conditioner compressor is forced out). |
t
| The mechanically driven air conditioner compressor is driven via a belt or shaft by the engine. The electrically driven air conditioner compressor is driven via an electric motor attached directly to the air conditioner compressor (e.g. on vehicles with hybrid drive). |
