JUDO QUICKSOFT-DUO 7
Intended Use
2.1 Water pressure
The water pressure must be between 2 bar
(29 psi) and 7 bar (101.5 psi).
The water pressure must not fall below 2 bar
(29 psi), as otherwise the function can be
impaired! If the softener is not regularly
regenerated, this can result in a pressure
loss and impairment of the softening function.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If the water pressure is over 7 bar (101.5
psi) a pressure reducer must be installed
upstream of the softener (see Fig. 2). An
operating pressure of over 7 bar (101.5 psi)
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 bar (435 psi)
frequently occur. This can cause damage to
important functional interior parts of the
controls. The optimum operating pressure
for the softener lies between 3 bar (43.5 psi)
and 5 bar (72.5 psi). It works most econom-
ically 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 (IP44).
ATTENTION
(see chapter “Safety information and dan-
gers 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 5 bar
(72.5 psi) to 7 bar (101.5 psi) we
recommend installation of a pres-
sure 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 24 VDC, with which the system’s
electronics are operated. Never use
any other power packs.
