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

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).
