Connection Diagram For Cleaning (Flushing), Vehicles With High-Voltage System (With Additional A/C System Functions Such As Heat Pump Operation)

The refrigerant circuit is cleaned in multiple flushing cycles. Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT and REFRIGERANT CIRCUIT (Cleaning the A/C system refrigerant circuit).

To flush, the circuit is divided into multiple sections and then cleaned during one flushing cycle at a time. It is divided by activating the installed electrically activated valves and using the installed manual shut-off valves. Refer to REFRIGERANT CIRCUIT (Cleaning the A/C system refrigerant circuit).

The design of the different flushing circuits for these vehicles is described in the respective vehicle-specific repair information. Refer to REFRIGERANT CIRCUIT (Cleaning the A/C system refrigerant circuit). Refer to CONNECTION DIAGRAM FOR CLEANING (FLUSHING), REFRIGERANT CIRCUIT WITH EXPANSION VALVE AND RECEIVER/DRYER .
