  Place the resonating diaphragm (

10

) on the head plate (

12

). 

Make sure that the ridge on the underside is properly placed in 

the groove of the head plate (

12

). Additionally, make sure that 

the protruding part of the resonating diaphragm is placed on 
the side of the dampening element. 

  Place the connecting plate (

9

) on the head plate (

12

). Observe 

the direction of the arrow 

► on both parts for easier assembly. 

The arrows must point in the same direction. 

  Tighten the four damper screws (

8

) in a diagonal sequence. 

Tightening torque 1.2Nm. 

  Place both valves (

7

) and both O-rings (

6

) into the connecting 

plate.  

  Snap the intermediate plate (

5

) into the connection plate (

9

). 

Observe the direction of the arrow 

► on both parts for easier 

assembly. The arrows must point in the same direction. 

 Place complete head (

2

) onto the pump housing (

4

). 

 Insert the four head screws (

1

) and tighten the screws in a di-

agonal sequence. Tightening torque 1.2Nm. 

 Re-connect the hoses to the pump head. 

 

 

 

 

CAUTION 

Caution, escaping liquid 

After assembly, the pump may not be leak-tight due to incorrect 
assembly, damaged or soiled seal faces, or other reasons. 

  Run the pump for several minutes with a harmless medium 

at maximum operating pressure. 

  Check that the pump is leak-tight.
