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).

7. Operation

The filter and pressure regulation functions work
completely autonomously without the need for ope-
ration. For impeccable, hygienic enjoyment of drin-
king water in accordance with the standards, it is
only necessary to replace the filter element at least
every 6 months.

7.1 Replace filter

With the new single lever operation, replacing the
filter element is easy and only takes seconds:
1. Slowly unlock the stopcock (6), thus
simultaneously and automatically stopping
the water (A1).
Note: The stopcock (6) is for maintenance
purposes only, i.e. for replacing the filter element.
It is not intended as the main shut-off for the water
supply.

2. Lift the single lever to approx. 130° (B1) – Pull
out the supporting core, incl. filter cup and filter
element (C1).
3. Dispose of the used filter element or – for
optimum hygiene – the complete hygienic vault
(environmentally-friendly plastic recycling).
4. Insert the new filter element or hygienic vault (A2),
close the lever (B2). Slowly release the stopcock/
unlocking device (6) (90° anti-clockwise) (C2).

8. Reminder service

With the BWT reminder service, BWT's mainte-
nance information service will remind you on a
regular basis when it is time to change the filter
element and also provide important hints and tips
on hygiene. In combination with the reminder ser-
vice and the regular change of the filter element
or hygiene kit, an extended 10-year E1 guarantee
is available, depending on the national subsidiary
(see item 10).
