9.1.2. Filter
Interval: every 2 months
• The filter must be cleaned by reverse rinsing regularly, at
the latest every 2 months
• Non-compliance can lead to the filter becoming blocked
This results in a drop in pressure and decreasing water
flow
• The filter meshes are made of stainless steel. A red
coating as a consequence of rust from the pipelines has no
influence on function or the way the filter works
Do not forget to do a visual check of the ball valve.
Replace if it is dripping!
9.1.3. Check valve
Interval: once a year
1. Close shutoff valve on inlet
2. Open test valve
• Until the pressure is released, some water will flow out
of the test valve. After a short period of time the water
flow should stop. If the water continues to drip or run,
then the check valve must be replaced - see servicing
of check valve
3. Close test valve again
4. Slowly open shutoff valve on inlet
9.2. Maintenance
9.2.1. Pressure reducing valve
Frequency: every 1-3 years (depending on local
operating conditions)
To be carried out by an installation company
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Loosen slotted screw
• Do not remove slotted screw
Caution !
There is a spring in the spring bonnet. It may cause
injuries if the spring is derailing.
• Make sure tension in compression spring is slak-
kened!
5. Slacken tension in compression spring
• Turn adjustment handle counter clockwise (-) until it
does not move any more
• Do not turn in too far!
6. Unscrew spring bonnet
• Use double ring wrench ZR10K
7. Remove slip ring
8. Remove valve insert with a pair of pliers
9. Unscrew filter cup and guide piece
• Use double ring wrench ZR10K

are in good condition, and if necessary replace the entire
valve insert
12. Reassemble in reverse order
Press in diaphragm with finger before inserting slip
ring
Screw in filter bowl hand-tight (without tools)

9.2.3. Check valve
To be carried out by an installation company
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Replace check valve
5. Slowly open shut off valves on inlet and outlet
9.3. Adjusting the setting scale
If the adjustment knob is removed, this setting is lost. A new
setting can be achieved using a pressure gauge.
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Loosen slotted screw
• Do not remove slotted screw
5. Slowly open shutoff valve on inlet
6. Set desired outlet pressure (e.g. 4 bar)
7. Align scale (e.g. 4) in middle of viewing window
8. Retighten slotted screw
9. Slowly open shutoff valve on outlet
