JUDO BIOSTAT-COMBIMAT
Intended Use
2.1
Water pressure
The water pressure must be between 22 psi
(150 kPa) and 116 psi (800 kPa).
If the water treatment device is not regularily
regenerated, this can result in a pressure
loss and impairment of the softening func-
tion.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If the water pressure is more than 116 psi
(800 kPa) a pressure reducer must be
installed before the water treatment device
(see Fig. 2). An operating pressure of more
than 116 psi (800 kPa) can lead to malfunc-
tion and failure.
The optimal operating pressure for the water
treatment device lies between 44 psi (300
kPa) and 73 psi (500 kPa). It works most
economically under these pressure condi-
tions. In modern sanitary installations (in
particular where single lever mixers are
used), despite normal system pressure
conditions, peak pressures of up to over 440
psi (3000 kPa) frequently occur. This can
cause damage to important functional inte-
rior parts of the water treatment device.
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
water treatment device can be damaged by
water which escapes from the water treat-
ment device during “Cleaning - Flushing” 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 water treatment
device must therefore be splash proof and
comply with the legal regulations for wet
rooms (IP44).

Pressure reducer upstream of the water
treatment device.
For a water pressure of 73 psi
(500 kPa) to 116 psi (800 kPa) we
recommend the installation of a
pressure reducer.

There must not be any electrical
cables and devices underneath or in
the immediate vicinity of the water
treatment device!
