• Note flow direction
• Install without tension or bending stresses
3. Set outlet pressure
4. Seal in pressure gauges
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. Close shut-off valve on outlet
4. Loosen hexagon nut on spring bonnet
5. Slacken tension in compression spring
6. Slowly open shut-off valve on inlet
7. Rotate adjustment screw, until the pressure gauge
shows the desired value
8. Retighten hexagon nut
9. 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.

during assembly
Shut-off valves up- or downstream of the
pressure reducing valve are not fully open
Pressure reducing valve is not set to the
desired outlet pressure

Close shut-off valve on outlet
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)
Slowly open shut-off valve on outlet
Close shut-off valve on inlet
Release pressure on outlet side (e.g. through water
tap)
Close shut-off valve on outlet
Loosen hexagon nut on spring bonnet
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!
Slacken tension in compression spring
• Turn control adjustment screw to the left (-) until it
does not move any more
Unscrew spring bonnet
Check the cartridge insert for fault-free condition and
replace insert or sealing parts if necessary.
Reassemble in reverse order
Disposal
Remedy
Replace diaphragm
Retighten the screws
Insert O-ring
Open the shut-off valves fully
Set outlet pressure
Fit pressure reducing valve in flow
direction (note direction of arrow on
housing)
Call Technical Customer Service
Replace valve insert
Check check valve, safety group etc.
