Judo i-soft - Water pressure; Notes on special dangers

JUDO i-soft 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.
The optimum operating pressure for the
softener lies between 3 bar (43.5 psi) and
5 bar (72.5 psi). 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 through 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 components in the
electrical circuit can get hot during opera-
tion. Furthermore, moving parts pose a
potential danger.
Potential-free output
Switching voltage................maximal 24 V
Current...................................maximal 1 A
(see chapter “Potential-free error message”)
Fig. 2: Pressure reducer upstream of the unit
For a water pressure of 5 bar
(72.5 psi) to 7 bar (101.5 psi) we
recommend installation of a pres-
sure reducer.

1 = Pressure reducer
There must not be any electrical
cables and devices underneath or in
the immediate vicinity of the softener!
The mains voltage is reduced to a
safe, extra-low voltage of 24 V in the
transformer, with which the system’s
electronics are operated. Never use
any other transformer.
Only use low voltage for remote
transmission of error messages via
the potential-free output!
