3.1 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

3.2 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
The green adjustment knob must stay plugged on to
prevent dirt from entering.
4
Start-up
4.1 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 manometer (standard version)
4.
Close shut-off valve on outlet
5.
Fit adjustment knob
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.
Slowly open shut-off valve on outlet

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:
5.1 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 5.2 Maintenance)
3.
Slowly open shut-off valve on outlet
