| Charging the refrigerant circuit with the service station |
WARNING | High-voltage on the high-voltage system. Danger of electric shock on air conditioner compressor! |
|
| l
| Basically, the work process must be carried out exactly as described in the instructions manual of the service station. |
| l
| Before charging the refrigerant, correct the amount of refrigerant oil inside the refrigerant circuit → Rep. gr.87. |
| l
| The total amount of refrigerant can be charged at either the low or high pressure side. |
| Charging the refrigerant circuit. |
| –
| Vacuum the refrigerant circuit with the service station → Chapter. |
| –
| Turn the wheel on the quick coupling adaptor (close). |
| –
| Allow the charging hose to fill with refrigerant. |
| –
| Turn the wheel on the quick coupling adaptor (do not force the valve), and charge the circuit with the specified amount of refrigerant. |
| –
| Remove the air conditioning service station. |
Note | If the air conditioner compressor is removed, the poly V-belt / free pulley must be turned about 10 turns by hand before starting for the first time. This prevents damage being caused when the air conditioner is turned on for the first time by a sudden increase of the fluid quantity in the air conditioner compressor (when oil is located in the cylinder of the air conditioner compressor, this will be pressed out by the rotation). |
| –
| Start the engine with the compressor disconnected (version with electromagnetic coupling). |
| –
| Set the compressor to its lowest power setting, "Econ" mode or A/C disconnected (version with regulating valve without electromagnetic coupling). |
| –
| Wait for the engine to start idling at a stable speed. |
| –
| Switch on compressor and allow system to run at idle for at least 2 minutes. |
| –
| If necessary, check the pressures in the refrigerant circuit with the service station. |
| –
| Turn the wheel on the quick coupling adaptor (close). |
| –
| Remove the hoses from the refrigerant circuit. |
| –
| Replace the protective caps. |
