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
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!
Thoroughly flush pipework
Install pressure reducing valve
• Note flow direction
• Install without tension or bending stresses
Set outlet pressure
Start-up
Set outlet pressure min. 1 bar under inlet pressure.
Close shut-off valve on inlet
Release pressure on outlet side (e.g. through water
tap)
Fit pressure gauge (optional)
Close shut-off valve on outlet
Loosen slotted screw
• Do not remove slotted screw
Slacken tension in compression spring
• Turn adjustment handle counter clockwise (-) until
it does not move any more
Slowly open shut-off valve on inlet
Turn adjuster knob until the manometer shows the
desired value
Retighten slotted screw
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.
Close shut-off valve on outlet
Check outlet pressure using a pressure meter when
there is zero through-flow
