| Connecting the air conditioning service station for carrying out measurements and tests |
| l
| Depending on the type of tools chosen, there may be differences in the work process. The specific handling instructions for each tool must be taken into account. |
Note | Basically, the work process must be carried out exactly as described in the instructions manual of the air-conditioner service station -SAT 4006D-. |
| In order to prevent air or humidity from entering the refrigerant circuit through the charging hoses, they must be connected as follows: |
| –
| Connect the service station to the electrical power source. |
| –
| Remove the caps from the service connections or valve connections (on the specific refrigerant circuit of the vehicle). |
| –
| Remove the filling hoses. |
Note | Connect the charging hoses with quick couplings to the service connections on the refrigerant circuit. |
Caution | Never open valves on the low pressure and high pressure sides when the engine is running. Otherwise the air conditioner compressor or the air conditioning service station may be affected by a „short circuit“ between the low pressure and high pressure sides in the refrigerant circuit as long as the air conditioner is being operated. |
|
| –
| Only turn the handwheel in the quick connector adapter far enough until the valve has been opened safely in the service coupling (observe the pressure gauge, do not apply excessive pressure to the valve). |
| –
| Start the engine and perform the planned measurements or checks. |
| –
| Compare the values obtained with the required measurement values → Chapter |
| –
| Before removing the quick connector, close the connection by turning the handwheel outwards. |
