4. Installation pre-requisites

Heed local installation regulations, general guide-
lines and technical data. Install filters in cold water
pipes upstream from the objects to be protected.
Caution: The installation site must be frostproof
and avoid disruptive influences (e.g. solvent va-
pours, heating oil, washing alkalis, all kinds of
chemicals, UV radiation and heat sources above
40 °C).
Caution: keep plastic components free from oil
and fat, solvents and acids and base cleaners.

5. Installation

5.1 Check the direction of flow and change if
necessary (only Inline version)
In the delivery state the direction of flow is from
left to right (heed flow direction arrow - visible on
the brass body below the handle). It is possible to
change this prior to filter installation - without con-
nection screw joints and manometer:
- Turn stopcock/
unlocking device (6)
to the 'open' position
(90° clockwise)
- Open lever (1) by
approx. 80° - 90°
- Remove the black
cover on the reverse
of the filter
- Loosen bolt
(anti-rotation device)
- Rotate the brass
housing by 180°
- Reinsert the bolt
(anti-rotation device)
The direction of flow is
now from right to left.

5.2 Install filter - Inline version
Mount the screw connection including the flat gas-
ket enclosed with the filter - the screw connection
with the backflow preventer must be positioned on
the input side (only E1 NEU HWS). Seal the mano-
meter (5) which is also enclosed (only E1 NEU HWS).
Then install the filter according to the nominal width
into the similarly dimensioned cold water pipe and
upstream from the objects to be protected.
HydroMODUL-Version:
Install filter according to its nominal width in cold
water pipes of the same dimensions.
Assemble the connection fittings (2) in the pipe and
install filter in flow direction (see flow direc tion ar-
row) in the horizontal cold water pipe.
Connection to the connecting module ¾" - 1¼":
1. Turn the retaining ring to the left until it stops.
2. Push the unit's catches into the recesses
3. and rotate the unit by 45º clockwise until it
stops.
4. Pull the retaining ring with both hands to-
wards the unit until it locks into place. The
unit is now protected against accidental
twisting. To loosen the filter, press the retai-
ning ring towards the connecting module
5.3 Install wall moun-
ting
80-120
The wall mounting is pre-
installed on the filter. It
is fixed to the wall using
the supplied bolts and
dowels (2 x KA40 or O 6
mm) in the wall.

6. Commissioning

Check filter for proper installation.
6.1 Set pressure reducer (only
E1 NEU HWS)
The pressure reducer is under
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. 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
pressure of the hot water safety valve (DIN 1988-
200).

7. Operation

The filter and pressure regulation functions work
completely autonomously without the need for
operation. For impeccable, hygienic enjoyment of
drinking 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 ele-
ment (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).
