1 Attach universal adapter (1) for pressure pump with fine adjustment to expansion reservoir.
Shutoff cocks (2, 3) on filling unit (4) must be shut.
2 Connect universal adapter (1) to the filing device (4).
3 Connect Venturi nozzle (5) to the filing device (4).
4 Connect compressed air hose (6) to the Venturi nozzle (5).
5 Open shutoff lever (3) until the pointer on the filling device (4) is located in the green area (- 0.85 to - 0.9 bar). Afterwards another 2 minutes for further evacuation.
6 Carefully open the shutoff lever (2) until the hose (7) at the filling device (4) is filled with coolant.
7 Close shutoff cocks (2, 3) and disconnect Venturi nozzle (5).
8 Allow cooling system to rest for one minute.

9 Open shutoff lever (2) and fill the cooling system up to the top marking at the coolant expansion reservoir.
10 Close shutoff lever (2).
11 Open shutoff lever (3) and create pressure compensation in the cooling system.
