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
10. Remove slotted ring
11. Check that sealing ring, edge of nozzle and slotted ring
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)
13. Set outlet pressure and adjust setting scale
9.2.2. 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!

9.3. 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
9.4. Cleaning
Caution !
Do not use any cleansers that contain solvents and/or
alcohol for cleaning the plastic parts, because this can
cause damage to the plastic components - water
damage could result.
If necessary, the filter bowl and the filter can be cleaned.
To be carried out by an installation company or the
operator.
Detergents must not be allowed to enter the environ-
ment or the sewerage system!
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Close shutoff valve on outlet
4. Unscrew filter bowl
• Use double ring wrench ZR10K
5. Remove filter, clean and reinsert
6. Place O-ring onto filter bowl
7. Screw in filter bowl hand-tight (without tools)
8. Slowly open shutoff valve on inlet
9. Slowly open shutoff valve on outlet
10. Disposal
• Dezincification resistant brass housing
• High-quality synthetic material spring bonnet
• High-quality synthetic material valve insert
• Stainless steel fine filter
• Shock-resistant, clear transparent synthetic material filter
bowl
• Fibre-reinforced NBR diaphragm
• NBR seals
Observe the local requirements regarding correct waste
recycling/disposal!
