9.4.2 Changing the cartridge

If additional water is expelled from the bypass line and/or 

the relief bores in the product when the spray unit is actu-

ated then the cartridge in the pressure housing must be re-

A pre-assembled cartridge (material number 9.919-046.0) 

may be replaced by untrained technical personnel as fol-

lows.

ATTENTION

Improper installation

Improper installation with damaged or dirty components 
can lead to malfunctions and damage to the product.
Perform a visual inspection of all spray device elements 
before installation.
All threads must be clean and undamaged.
The sealing surfaces of mating components must not have 
any scratches or scoring.
A non-pre-assembled cartridge may only be replaced by 
trained technical personnel.

(See illustration on page 2)

1. Release the bypass screw from the pressure housing 

and remove together with the cartridge.

2. Remove the spring from the pressure housing and re-

place with a new spring.

3. Disconnect the bypass screw from the cartridge.

4. Remove the seal (O-ring) from the groove in the bypass 

screw. 

5. Fit the seal (O-ring) in the groove.

6. Fit the bypass screw positively into the pre-assembled 

cartridge (material number 9.919-046.0).

7. Coat the thread of the bypass screw with thread instal-

lation paste before installation (see Chapter 12.2 Con-

sumables).

8. Coat the fitting surfaces of the cartridge with anti-seize 

installation (see Chapter 12.2 Consumables).
