4 Assembly
4.1 Installation Guidelines
• Horizontal and vertical installation position possible
– In vertical installation position spring bonnet with
adjustment knob facing upwards
• Install shut-off valves
• The installation location should be protected against
frost and be easily accessible
– Pressure gauge can be read off easily
– Simplified maintenance and cleaning
• To guarantee perfect functioning, a filter must be
inserted ahead of the pressure reducing valve
• Provide a straight section of pipework of at least five
times the nominal valve size after the pressure
reducing valve (in accordance with EN 806-2)
• Requires regular maintenance in accordance with
EN 806-5
4.2 Assembly instructions
CAUTION!
When using soldering connections, do not solder
the connections together with the pressure
reducing valve! High temperature will irreparably
damage important internal working components!
1. Thoroughly flush pipework
2. Install pressure reducing valve
• Note flow direction
• Install without tension or bending stresses
3. Set outlet pressure
5 Start-up
5.1 Setting outlet pressure
Set outlet pressure min. 1 bar under inlet pressure.
1. Close shut-off valve on inlet
2. Release pressure on outlet side (e.g. through water
tap)
3. Fit pressure gauge (optional)
4. Close shut-off valve on outlet
5. Loosen slotted screw
• Do not remove slotted screw
6. Slacken tension in compression spring
• Turn adjustment handle counter clockwise (-) until
it does not move any more
7. Slowly open shut-off valve on inlet
8. Turn adjuster knob until the manometer shows the
desired value
9. Retighten slotted screw
10. Slowly open shut-off valve on outlet
6 Maintenance
In order to comply with EN 806-5, water fixtures must
be inspected and serviced on an annual basis.
As all maintenance work must be carried out by an
installation company, it is recommended that a
servicing contract should be taken out.
In accordance with EN 806-5, the following measures must
be taken:
6.1 Inspection
1. Close shut-off valve on outlet
2. Check outlet pressure using a pressure meter when
there is zero through-flow

• If the pressure is increasing slowly, the valve may
be dirty or defective. In this instance, carry out
servicing and cleaning (See 6.2 Maintenance)
3. Slowly open shut-off valve on outlet
6.2 Maintenance
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.
Detergents must not be allowed to enter the
environment or the sewerage system!
1. Close shut-off valve on inlet
2. Release pressure on outlet side (e.g. through water
tap)
3. Close shut-off 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
slackened!
5. Slacken tension in compression spring
• Turn adjustment handle counter clockwise (-) until
it does not move any more
6. Unscrew spring bonnet
• Use double ring wrench ZR06K
7. Remove slip ring
8. Remove valve insert with a pair of pliers
9. Remove filter and clean
10. Check that sealing ring, edge of nozzle and slotted
ring are in good condition, and if necessary replace
the entire valve insert
11. Reassemble in reverse order
Press in diaphragm with finger before inserting slip
ring
12. Adjust setting scale and set outlet pressure
7 Disposal
Observe the local requirements regarding correct waste
recycling/disposal!

Problem Cause Remedy
Beating sounds Pressure reducing valve is too large Call Technical Customer Service
Water is escaping from the spring bonnet Diaphragm in valve insert is faulty Replace valve insert
Too little or no water pressure Shut-off valves up- or downstream of the
pressure reducing valve are not fully
open
Open the shut-off valves fully
Pressure reducing valve is not set to the
desired outlet pressure
Set outlet pressure
Filter in pressure reducing valve is
contaminated
Clean or replace filter
Pressure reducing valve is not fitted in
flow direction
Fit pressure reducing valve in flow
direction (note direction of arrow on
housing)
The outlet pressure set does not remain
constant
Filter in pressure reducing valve is
contaminated or worn
Clean or replace filter
Valve insert, sealing ring or edge of
nozzle is contaminated or worn
Replace valve insert
Rising pressure on outlet (e.g. in boiler) Check check valve, safety group etc.
