Cooler vacuum filling device

1	 Attach tester cap (1) to the expansion reservoir.

2	 Attach control unit (2) to  tester cap (1).

3	 Attach Venturi nozzle (3) to  control unit (2).

4	 Close feed valve (4) and  drain valve (5).

S20.20-4526-06

5	 Attach feed hose (6) to  coolant reservoir (7). Model 447, model 448 with engine 274  MODEL 447 with ENGINE 622, 651 

 To prevent air from being drawn in, ensure that the  coolant reservoir (7) contains more coolant than the maximum filling capacity of the engine cooling system.

6	 Insert waste air hose (8) into suitable empty container.

7	Attach compressed-air hose (9) to  Venturi nozzle (3) and apply compressed air.

8	 Open drain valve (5).

9	 Open feed valve (4) for a short time until the  feed hose (6) has filled with coolant.

 A vacuum is created in the engine cooling system.

10	 Close drain valve (5) if display of the  control unit (2) is in the green area.

11	Remove compressed-air hose (9) from  Venturi nozzle (3) and observe whether vacuum remains stable for 30 s.

If vacuum does not remain stable for 30 s:



Check hoses and connections, repair affected components and repeat test.

12	 Open feed valve (4).

 The engine cooling system is now filled.

13	 Open drain valve (5) as soon as coolant is no longer suctioned.

 The remaining existing vacuum will be removed in this way.

14	 Remove control unit (2) along with all the connections and  tester cap (1).

15	Correct coolant level on expansion reservoir.

 The coolant level must not exceed the MAX marking.
