6. Re-setting the pressure
Changing the factory settings is the
performer’s sole responsibility.
You must not try to repair the
JRGURED UP pressure reducer.
The pressure settings of the pressure reducer
can be adjusted as follows:
Reduce pressure by opening (about 0.5 L/min)
one of the taps. Apply the Allen key (SW 6) to the
setscrew. Turning the key clockwise increases,
turning it counter-clockwise lowers the second-
ary pressure.
A 360-degree turn of the key corresponds to a
change in pressure of about 30 kPa (0.3 bar).
Close the open tap after resetting the pressure
reducer.
Check the pressure adjustment with
a pressure gauge at static pressure
(zero consumption).
Make sure that the pressure adjustment
complies with local regulations and
standards.
