Connection Diagram For Cleaning (Flushing), Vehicles With High-Voltage System (Without Additional A/C System Functions)
NOTE:
The refrigerant circuit is cleaned in two flushing cycles (first the section with the evaporator in the front heater and A/C unit and then the section with the high-voltage battery heat exchanger or the evaporator in the battery cooling module). Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT .
For vehicles with two evaporators or an evaporator with a heat exchanger, disconnect the circuit to the second evaporator or to the heat exchanger from the circuit for the first evaporator using the manual shut-off valves and flush it in a separate work procedure. Refer to ADAPTER FOR ASSEMBLING FLUSHING CIRCUIT and Refrigerant Circuit .
The design of the different flushing circuits for this vehicle is similar to a vehicle with two evaporators.
