The pressure setting of the pressure- redu cing
valve can be changed as follows:
Relief the pressure reducing valve due to open
a outlet 16 (approx. 0.5 l/min) after the JRG
domestic water station.
Set the Allen key 13 at the pressure adjust ment
14. Turning the key clockwise, the secondary
pressure increases, turning it counterclockwise
it decreases.
One full rotation of the key through 360 deg.
corresponds to a pressure change of 0,3 bar
(DN 1– 2).
Close outlet 16 after pressure change.

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 regu-
lations of the SVGW/DIN 1988/ÖVGW
and of the local water utility.
The operating and maintenance instructions are
to be given to the building owner when handing
over the installation.
