NOTE:

The illustrated check valve -3- is installed for example on a Audi Q7 e-tron. Refer to the appropriate information (REFRIGERANT CIRCUIT / REFRIGERANT CIRCUIT / REFRIGERANT CIRCUIT ) (vehicle-specific repair information).

The check valves in the refrigerant circuit in the flow direction have a specified residual pressure (approximately 0.1 bar or 100 mbar (1.45 psi)). So that the refrigerant circuit can be completely evacuates (residual pressure less than 5 mbar (72.5 psi)) all electrically activated valves must be opened.

Depending on the version the flow direction can be marked using a sticker.
