7.2. Assembly instructions
1. Thoroughly flush pipework
2. Install pressure reducing valve
• Note flow direction
• Install without tension or bending stresses
3. Seal pressure gauge
8. Start-up

8.1. Setting outlet pressure

Set outlet pressure 1 bar minimum under inlet 
pressure.
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 hexagon nut on spring bonnet
5. Slacken tension in compression spring
6. Slowly open shutoff valve on inlet
7. Rotate adjustment screw, until the pressure gauge shows
the desired value
8. Retighten hexagon nut
9. Slowly open shutoff valve on outlet
9. Maintenance
We recommend a planned maintenance contract with
an installation company
In accordance with DIN EN806-5, the following measures
must be taken:
9.1. Inspection

9.1.1. Pressure reducing valve

Interval: once a year
1. Close shutoff 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
3. Slowly open shutoff valve on outlet
9.2. Maintenance
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 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 slak-
kened!
5. Slacken tension in compression spring
