5. Assembly
5.1. Installations Guidelines
It is necessary during installation to follow the installation
instructions, to comply with local requirements and to follow
the codes of good practice.
• Install in horizontal pipework with spring bonnet directed
upwards
• Install shutoff valves
• The installation location should be protected against frost
and be easily accessible
- Pressure gauge can be read off easily
- Simplified maintenance and cleaning
• For residential applications where maximum protection
against dirt is required, install a fine filter upstream 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 DIN 1988, Part 5)
5.2. Assembly instructions
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
The green adjustment knob must stay plugged on to
prevent dirt from entering.
6. Start-up
6.1. Setting outlet pressure
Set outlet pressure min. 1 bar under inlet pressure.
1. Close shutoff valve on inlet
2. Release pressure on outlet side (e.g. through water tap)
3. Fit manometer (standard version)
4. Close shutoff valve on outlet
5. Fit adjustment knob
6. Slacken tension in compression spring
• Turn control handle to the left (-) until it does not move
any more
7. Slowly open shutoff valve on inlet
8. Turn adjuster knob until the manometer shows the
desired value.
9. Slowly open shutoff valve on outlet
7. Maintenance
We recommend a planned maintenance contract with
an installation company
In accordance with DIN 1988, part 8, the following measures
must be taken:
7.1. Inspection
7.1.1. Pressure reducing valve
Interval: once a year
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
3. Slowly open shutoff valve on outlet
7.2. 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. Fit adjustment knob
5. Slacken tension in compression spring
• Turn control handle to the left (-) until it does not move
any more
6. Unscrew spring bonnet
7. Remove valve insert with a pair of pliers
8. Remove filter and clean
9. Check that sealing ring, edge of nozzle and 'o'-ring are in
good condition, and if necessary replace the entire valve
insert
10. Reassemble in reverse order
11. Set outlet pressure
