Simply remove the cap (2) to reach the pressure re-
ducer. The pressure reducer is set to a back pressure
of 4 bar at the factory. To change the back pressure,
loosen the locking screw (10) and turn the rotary
knob (11). The back pressure can be changed by
turning the setting knob (11) (control range 2 - 6
bar).
Clockwise rotation = higher back pressure.
Anti-clockwise = lower back pressure.
The manometer (5) displays the back pressure. Du-
ring setting, an outlet valve downstream from the
pressure reducer must be briefly opened and closed
again a number of times. When water is removed,
the back pressure is temporarily reduced. The back
pressure must not exceed 80 % of the response pres-
sure of the hot water safety valve (DIN 1988-200).

king water in accordance with the standards, it is
only necessary to replace the filter element at least
every 6 months. The integrated LED display gives a
timely warning by means of a visual signal: the red
LED flashes every 5 seconds.
- Flashing interval after 6 months/ 182 days have
elapsed: a red LED flashes every 5 seconds.
- Flashing period: after expiry of time until filter
change or reset occurs.
