Intended Use
2.1
Water pressure
The water pressure must be between 2 bars
and 7 bars.
The water pressure must not fall below 2
bars, as otherwise the function can be im-
paired! If the Softener is not regularly regen-
erated, this can result in a pressure loss and
impairment of the softening function.
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
If the
water pressure is over 7 bars
a pres-
sure reducer must be installed
upstream
of
the Softener (see Fig. 2). An operating pres-
sure of over 7 bars can lead to malfunction
and failure.
In modern sanitary installations (in particular
where single lever mixers are used), despite
normal system pressure conditions, peak
pressures of up to over 30 bars frequently
occur. This can cause damage to important
functional interior parts of the controls. The
optimum operating pressure for the Softener
lies between 3 bars and 5 bars. It works
most economically under these pressure
conditions.
2.2
Notes on special dangers
2.2.1 Electrical equipment / installa-
tions
Electrical devices/equipment, which are not
splash proof and which are located near the
Softener can be damaged by water which
escapes from the Softener during regenera-
tion or improper use. If the electrical devices
/installations are connected to the power
supply, a short circuit can also occur. In this
case there is a risk of people suffering an
electric shock. Electrical devices/equipment
located near the Softener must therefore be
splash proof and comply with the legal regu-
lations for wet rooms (IP44).
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
Caution when touching the unit when the
cover is removed! The load impedances in
the electrical circuit can get hot during oper-
ation.

1 = Pressure reducer
For a
water pressure of 5 bars to
7 bars
we recommend installation
of a pressure reducer.
There must not be any electrical ca-
bles and devices underneath or in the
immediate vicinity of the Softener!
In the power pack the mains voltage
is reduced to a safe, extra-low voltage
of 15 V, with which the system’s elec-
tronics are operated. Never use any
other power packs.
