6.1 Set pressure reducer
(only Cillit C1 HWS)
The pressure reducer is un-
der the cap.
Simply remove the cap (2) to
reach the pressure reducer.
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.
During 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 redu-
ced. The back pressure must not exceed 80 %
of the response pressure of the hot water safety
valve (DIN 1988-200).

least every 6 months. The integrated LED display
gives a timely warning by means of a visual sig-
nal: the red LED flashes every 5 seconds.

have elapsed: a red LED flashes every 5 se-
conds.
