Intended Use
2.1
Water pressure
The water pressure must be between 29 psi
(200 kPa) and 102 psi (700 kPa).
The water pressure must not fall below
29 psi (200 kPa), as otherwise the function
can be impaired! If the softener is not regu-
larly regenerated, this can result in a pres-
sure loss and impairment of the softening
function.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If the water pressure is over 102 psi
(700 kPa)
a pressure reducer must
be installed upstream of the softener (see
Fig. 3). An operating pressure of over 102
psi (700 kPa) 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 435 psi (3000 kPa)
frequently occur. This can cause damage to
important functional interior parts of the
controls. The optimum operating pressure
for the softener lies between 44 psi
(300 kPa) and 73 psi (500 kPa). It works
most economically under these pressure
conditions.
2.2
Notes on special dangers
2.2.1 Electrical equipment /
installations
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 / equip-
ment located near the softener must there-
fore be splash proof and comply with the
legal regulations for wet rooms.
ATTENTION
(see chapter “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
operation.

1 = Pressure reducer
For a water pressure of 73 psi
(500 kPa) to 102 psi (700 kPa)
we recommend installation of a
pressure reducer.
There must not be any electrical
cables 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.
