| Checking pressures with restrictor and reservoir (with internally regulated compressor) |
Note | t
| Connect AC service station. |
| –
| Let the engine run at a speed of 2000 rpm. |
| –
| Observe pressure reading (e.g. pressure gauge) of air conditioner service station. |
Note | t
| The switching pressures of the refrigerant circuit switches are specific to the vehicle. |
| t
| The valve connection for the low-pressure switch or the evaporator must only be used on vehicles with no service connection on the low-pressure side and with a non-accessible connection on the compressor or collecting tank (measurement precission). Applies only for certain vehicles → heater and air conditioning; Rep. gr.87 or → air conditioning; Rep. gr.. |
