Main Wiring Diagram, Electrically-Driven A/C Compressor, Cleaning
WARNING: This page is about a different car, the 2023 Volkswagen Arteon. However, it is still accessible from the selected car via links, so may be relevant.
- A/C Service Station
- Refrigerant Hose
- From the high-pressure side A/C Service Station to the connector for the low-pressure side of the A/C compressor (larger diameter)
- Adapter to Connection for Low Pressure Side on A/C Compressor
- There are different versions. Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT .
- For example Refrigerant Circuits Adapter Set 1 - Adapter 41:VAS 6338/41A from the Refrigerant Circuits Adapter Set 1:VAS 6338/1 .
- use the Refrigerant Circuits Adapter Set - Adapter 48:VAS 6338/48 between the refrigerant hose -2- and the adapter -3-.
- Refrigerant Line
- To the A/C compressor connection on the adapter MAIN WIRING DIAGRAM, ELECTRICALLY-DRIVEN A/C COMPRESSOR, CLEANING List Item:Adapter to Connection for Low Pressure Side on A/C Compressor
- A/C Compressor
- A/C compressor is flushed in the flow direction (from the low pressure side input to the high pressure side output)
- Refrigerant Line
- To the A/C compressor connection on the adapter MAIN WIRING DIAGRAM, ELECTRICALLY-DRIVEN A/C COMPRESSOR, CLEANING List Item:Adapter to Connection for High-Pressure Side on A/C Compressor
- To remove the flushing circuit use for example a refrigerant line with the part number 7L6 820 721 BF. Refer to the Parts Information.
- Adapter to Connection for High-Pressure Side on A/C Compressor
- There are different versions. Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT .
- For example Refrigerant Circuits Adapter Set 1 - Adapter 40:VAS 6338/40A from the Refrigerant Circuits Adapter Set 1:VAS 6338/1 .
- Filler Hose to the Flushing Device
- from the connection to the high pressure side of the A/C compressor on the refrigerant circuit (smaller diameter) to the input of the flushing device.
- Refrigerant Circuit Flushing Device
- different versions and different design of the Refrigerant Circuit Flushing Device. Refer to the Parts Information.
- Depending on the design of the A/C Service Station and the flushing device for the refrigerant circuits, a connection for a service coupling can be installed on the output and may also be installed on the input of the flushing device.
- If a service connection with a valve is installed on the outlet of the flushing device, this valve must be all the way open when the service coupling is attached. A partially opened valve creates a constriction.
- If on the input of the flushing device a connection for a service coupling is present, modify the input so that the refrigerant hose which comes from the vehicle can be directly connected.
