Resetting the pressure- reducing valve
Any change to the factory pressu re
setting is carried out exclusive ly on the
responsibility of the per son doing so.
The pressure setting of the pressure-
redu cing valve can be changed as
follows:
Relieve (approx. 0.5 l/min.) the pressure redu-
cing valve by opening a tap 16. Set the Allen
key 13 at the pressure adjustment 14.
Turning the key clockwise, the secondary
pressure increases, turning it counterclock-
wise it decreases.
One full rotation of the key through 360 deg.
corresponds to a pressure change of:
Pressure -reducing valve
GN ½
Pressure- reducing valve
GN ¾– 2 ½
Close outlet 16 after pressure change.
Maintenance
35 kPa / 0,35 bar
30 kPa / 0,30 bar
The pressure setting has to be checked
with a pressure gauge at steady- state
pressure (no water consumption).
Attention must be paid, that the pres-
sure setting corresponds to the local
regulations.
Repairs to the pressure-reducing valve
JRGURED must not be attempted.
