Product information

3.1

Application

The water softening system is suitable for use
with cold drinking water having a maximum
water temperature of up to 30 °C.
ATTENTION
(see chapter 1.2 "Safety instructions and
dangers due to non-observation")
Usage limitations see chapter "Intended
use".
This water softening system is for protection
of water pipes and the water heater against
limescale deposits.
With partially softened water, devices and fit-
tings are preserved and the consumption of
washing and cleaning agents reduced.
Limescale deposits block the water
supply and therefore can result in in-
creased energy consumption.

Approval marks

Fig. 3 : DIN-DVGW marks
The devices comply with the technical regu-
lations for drinking water installation accord-
ing to DIN EN 806 ff. and the national sup-
plement DIN 1988 ff. as well as DIN
EN 1717. They have been tested and ap-
proved by the DVGW (German Technical
and Scientific Association for Gas and Wa-
ter) according to the requirements of DIN
EN 14743 and DIN 19636-100 for water sof-
tening systems (cation exchangers) and can
thus bear the DIN-DVGW mark.

Materials used

The materials used are resistant to the phys-
ical, chemical and corrosive loads expected
to be encountered in drinking water and fulfil
the specifications
EN 14743 and DIN 19636-100 ('Water sof-
tening systems (cation exchangers) in drink-
ing water installations'). All materials are hy-
gienically and physiologically harmless.
Plastics fulfil the KTW Guideline (Guideline
for the Hygienic Assessment of Organic Ma-
terials in Contact with Drinking water) of the
German Federal Environmental Agency
(UBA). Metallic materials fulfil the require-
ments of DIN 50930-6 (Effect of metallic ma-
terials on the quality of drinking water).

Installation

4.1 Requirements for the place of
installation
The installation room must be dry and
free from frost!
Unauthorised persons must not be able
to access the water softening system.
– The ambient temperature must not ex-
ceed 30 °C!
– A power connection with a permanent
supply, that is independent of the light
switch, must be available ("In operation"
LED (11) always on). Similarly a sewer
connection for the flushing water (3) and
the safety overflow of the brine tank (6).
– The water softening system can be in-
stalled in horizontal or vertical pipes. The
installation height depends on the pipe
course (minimum installation height from
the ground to the rotary flange fitting is
93 cm for a direct connection without
hoses). The salt filling opening which is
closed with a transparent hood (4) must
be readily accessible.
– So that it is possible to safely drain the
waste water (regeneration) during oper-
ation and also in the event that a system
