Intended use
2. Intended use
Installation and use of the water treatment
device are each subject to the applicable
national regulations.
Apart from the instruction manual and the le-
gally binding accident prevention provisions
applicable in the country and place of use,
the recognized technicalregulations for safe
and proper work must also be observed.
The water to be treated must comply with
the European Drinking Water Directive!
Always contact the manufacturer/supplier
before using water with a different quality or
with additives!
This water treatment device is suitable for
use in cold drinking water up to maximum
ambient temperature of 86 °F (30 °C).
It is produced according to the newest
standards of technology and the generally
accepted safety regulations in Germany.
The water treatment device may only be
used as described in the instruction manual.
Any other or further use is deemed not to be
intended use.
Additional dangers exist in case of non-
intended use and failure to observe the
danger symbols and safety information. The
manufacturer/supplier are not liable for any
losses or damage resulting from this. The
risk is solely borne by the user.
Intended use also includes observing the
instruction manual.
The manufacturer/supplier must always be
consulted before using the water treatment
device outside the use limitations given in
the instruction manual.
The water treatment device is only to be
used in a technically perfect condition, for
their intended use, safely and aware of the
dangers and with full observance of the
instruction manual!
Have any malfunctions corrected imme-
diately!
In order to be able to discharge safely the
wastewater in operation and in case of any
defect in the system, precise compliance
with the details stated in the chapter
“Requirements for the place of installation”
is necessary!
2.1 Water pressure
The water pressure must be between 22 psi
(1.5 bar) and 116 psi (8 bar).
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
(8 bar) a pressure reducer must be installed
before the water treatment device (see fig.
2). An operating pressure of more than 116
psi (8 bar) can lead to malfunction and
failure.
The optimal operating pressure for the water
treatment device lies between 44 psi (3 bar)
and 73 psi (5 bar). It works most economi-
cally under these pressure conditions. 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 (30 bar)
frequently occur. This can cause damage to
important functional interior 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).
Fig. 2: Pressure reducer upstream of the water
treatment device
For a water pressure of 73 psi
(5 bar) to 116 psi (8 bar) we recom-
mend the installation of a pressure
reducer.

Product information
3. Product information
3.1 Intended purpose
This water treatment device is suitable for
use in cold drinking water up to a maximum
water temperature of 86 °F (30 °C).
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Please refer to the chapter “Intended use”
for use restrictions.
This water treatment device reduces the
tendency of the water to precipitate out
excess calcium and thus protects the water-
pipes and water heaters from lime deposits.
Appliances and taps are protected.
3.2 Test marks
The devices conform to the technical regula-
tions for drinking water installations in accor-
dance with the German standard DIN 1988.
They comply with the requirements of the
work sheet W 510 (lime protection devices
for use in drinking water installations)issued
by the DVGW (Deutsche Vereinigung des
Gas- und Wasserfaches e.V.), the German
technical-scientific association for the gas
and water industries, and are entitled to bear
the DVGW mark (see fig. 3).
3.3 Materials used
The materials used are resistant to the
physical, chemical and corrosive loads to be
expected in the drinking water . All materials
are hygienically and
physiologically safe.
Plastics fulfill the official guideline of the
German Federal Environmental Agency as
well as the work sheet W 270 issued by the
DVGW. Metallic materials fulfil the require-
ments of the German standard DIN 50930-6
(influence on drinking water condition).
4. Installation
4.1 General
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
The unit may only be installed by skilled
personnel.
The chapter “Intended use”has always to be
observed !
The pipes must be able to support in a safe
way the water treatment device.
Otherwise mechanical damage or fractures/
bursts can occur in the pipes. This can result
in major water damage. People close to the
water treatment device are exposed to a
health risk due to the large quantities of
water released. Therefore, if necessary, the
pipes must be additionally fixed or
supported.
Always observe the given spacings to
ensure convenient operation and servicing
(see chapter “Mounting dimensions”).
A distance of at least 6 inch (150 mm) above
and below the water treatment device
is required in order to be able to carry out
properly all the maintenance and servicing
work.
Lime deposits restrain the water
flow and can therefore lead to an
increased energy consumption.
Fig. 3: DVGW mark

10 JUDO BIOSTAT 25 TGA
Installation
When installing the water treatment device
in the feed-pipe to the water heater, ensure
that the safety valve of the water heater is
located after the water treatment device in
the direction of flow.
4.2 Requirements for the place of
installation
The room where the unit is installed must
be dry and frost free!
Unauthorised persons must not have
access to the water treatment device!
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
– The ambient temperature must not
exceed 86 °F (30 °C)! At higher tempera-
tures or direct sun radiation the material
can be damaged.
– We recommend that the water treatment
device is installed after a backwash
protective filter, to prevent particles of
dirt and sand being swept in.
– Length of the power lead is approxi-
mately 118 inch (3 m).
– Particularly in the case of small cross-
sections and soft pipe materials, the
water pipes should be supported in the
vicinity of the connecting flange with two
pipe-clamps.
4.2.1 Installation position
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Always install the water treatment device in
a vertical position (± 5°)!
Unless, impairments of its function canoccur.
4.2.2 Power supply
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
A permanent power supply that is not
connected to a light switch must be avai-
lable. If the water treatment device is not
permanently supplied with power, there is
no warning in case of faults, and no water is
treated.
4.2.3 Mounting the built-in rotary
flange
The built-in rotary flange is used as a
connecting element between the pipe and
the water treatment device.
It is suitable for both, horizontally and verti-
cally mounted pipes.
The built-in rotary flange must be
installed in the direction of flow. This is
marked by a cast in arrow (see fig. 1).
If these instructions aren't respected, the
water treatment device doesn't work.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
The flange surface of the built-in rotary
flange must be in a vertical position! The
built-in rotary flange must be fitted thus that
mechanical stresses cannot occur! Other-
wise mechanical damages can arise at the
built-in rotary flange. This can lead to major
water damages.
In this case, people close to the water treat-
ment device are exposed to a health risk
due to the large quantities of water.
A power connection (120 V, 60 Hz),
which has to be permanently under
voltage, must be available.
A splash proof socket is required for
the power supply, in accordance with
the legal regulations for wet rooms.

JUDO BIOSTAT 25 TGA 11
Installation
Therefore, when mounting, ensure that no
large forces act on the pipe, built-in rotary
flange and water treatment device.
4.2.4 Mounting the water treatment
device
– After flushing the water pipe, remove the
assembly lid of the built-in rotary flange.
– Remove the white protective disc on the
connecting flange of the water treatment
device by unscrewing the four M6 Allen
screws.
Do not completely unscrew the screws
because of the bayonet connection!
– Lift up the water treatment device and
swivel it approx. 30° in an anti-clockwise
direction.
– Position it on the built-in rotary flange so
that the screw heads pass through the
bayonet fixing drill holes (see fig. 4 I).
– Swivel the water treatment device
approx. 30°back in a clockwise direction
and tighten the four Allen screws (see
fig. 4 II).
The profile of the profiled flange gasket must
point towards the built-in rotary flange (see
fig. 5). Failure to observe this can lead to
leaks and water escaping. This can cause
damage due to water to thehouse and its in-
stallations.
4.3 Discharging the flushing water
An adequately dimensioned wastewater
connection (e. g. floor drain) according to
DIN 1986 must be available for the flushing
water
.
The dimensioning depends on the local
circumstances (e. g. wastewater pipe
gradient, number of pipe bends, length of
the wastewater pipe, etc.). The dimen-
sioning must at least ensure that all the
wastewater can be discharged temporarily
coordinated.
If it is not possible to locate a drain connec-
tion directly under the water treatment
device, the wastewater hose can be routed
over the water treatment device.
The wastewater hose for the flushing water
must be led to the drainage channel without
any kinks.
In all options, a free discharge must be
ensured in accordance with EN 1717.
The loose end of the hose has to be firmly
fixed with the included adhesive tape at the
pipe or a similar object.

JUDO BIOSTAT 25 TGA 15
Operation
5.3.1 Treatment effect
The water treatment device works
completely automatically. The treatment
effect is adapted at the water flow. In the
feed to the water treatment device there is a
flow-meter.
The flow-meter consists of a propeller water
meter.
Due to the water flow the screw propeller,
that can be found in the propeller water
meter rotates, and a Hall Sensor receives
impulses from the magnet in the propeller.
The electronics then calculate the water flow
from the frequency and quantity of the
impulses. The electronics regulate the treat-
ment current referring to the relation that
exists between the applied voltage and the
treatment current as well as from the dura-
tion of the treatment current (impulse
length). The electronics optimise the treat-
ment current, according to the quality of the
water.
As soon as water flows, the water treatment
is indicated by the flashing of green LED 1
(see fig. 9).
5.3.2 Lime protection function
The water treatment device sets free the
minute seed crystals to which further lime
can attach itself. In the treatment section,
there is a titanium anode (positive pole) and
a circular stainless steel brush switched as
the cathode (negative pole). As soon as
water flows, there is a pulsating direct current
a
pplied to these two electrodes so that there
is a flow of electricity between the elec-
trodes. Dissolved calcium in the form of
calcium carbonate crystals is then deposited
on the cathode (the circular stainless steel
brushes). On cleaning, these crystals of
calcium carbonate are thrown off the sepa-
rate bristles by rotating the circular brush.
The crystals thus formed are minute micro-
crystals. Larger crystals which may possibly
also appear sink together with separate
loose brush particles to the bottom and are
flushed out via the flushing valve during
cleaning.
The lime particles can be seen in the
flushing water as very fine “sand”. The
microcrystals remain in suspension and
thus formseed crystals on which further lime
can be deposited. Principally in the warm
water field the growth of the crystals can be
realized by a gradual clouding of the water.
The crystals slowly grow large enough to be
able to disperse the rays of light. At that
stage, they are but a few thousandths of a
millimeter in size. But even these crystals
are small enough to remain in suspension
and to be flushed out with the water flow.
The same process goes on in the cold water
field, too, although the potential here for
deposition of lime is considerably less in
normal circumstances. Since the excess
lime (calcium) is now deposited at the seed
crystals, other surfaces (e. g. pipework,
boiler etc.) are not affected by lime deposits
so that heating elements for example no
longer fur up. Although this formation of
crystals does reduce the hardness of the
water, the reduction is so small that they
remain undetectable by means of simple
measuring instruments.

16 JUDO BIOSTAT 25 TGA
Operation
In the feed of the unit, is a propeller water
meter which can even detect such small
flows of water as 0.4 gpm (1.5 l/min).
Together with a microprocessor-controlled
electronics, optimal water treatment is
ensured at all times from tiny flows up to the
nominal capacity, and also depending on
the water quality by adapting the electrical
impulses.

Maintenance
5.5 Cleaning / flushing
Depending on the quality of the water and
the operating methods,a thin coatingof lime
is formed on the brush in the treatment
chamber. This lime layer must be removed
and flushed out of the water treatment
device at regular intervals.
The water treatment device has a device for
flushing the brush and a flush valve for
rinsing out the lime particles.
Cleaning / flushing is carried out automa-
tically by two electric motors.
During cleaning / flushing, the yellow LED 2
lights up.
The cleaning / flushing can be started manu-
ally
by operating the manual pushbutton (2).
6. Maintenance
6.1 Demand for maintenance
LED 3 flashes 3 years after commissioning
or the latest maintenance of the water treat-
ment device. At a water consumption of over
85.850 gal (325 m³) per year this time frame
reduces.
By this the controls signal that a mainte-
nance should be performed by the fitter or
the nearest customer service.
After four weeks the color of LED 3 changes
from yellow to red. A maintenance must be
performed now.
6.2 Failure to observe the
maintenance demand
If the maintenance demand (LED 3 red) is
ignored, water treatment will no longer take
place after 10 days. The LED 3 flashes red
then.
Make sure that the drain connec-
tion is functional before plugging
the power supply into the socket
(see chapter “Discharging the
flushing water”).
Contact the fitter or the nearest
customer service to perform a
maintenance (see chapter “Custo-
mer service”).

18 JUDO BIOSTAT 25 TGA
Maintenance
6.3 Warning message "Battery
low"
To ensure that cleaning / flushing is carried
out completely, even in case of a power
failure, the water treatment device has a 9 V
block battery installed as an emergency
power supply.
Before each cleaning / flushing a battery test
will be effected. A missing, unloaded or
defective battery is indicated by the flashing
of the red LED 4. A trigging of the container
flushing is then not possible.
6.4 Mounting of the panelling
Dismantling:
– Withdraw the upper / inferior clamping
fixture.
– Carefully pull apart the right and the left
panel parts by the handle cavities on
the back of the panelling.
– Remove the type plate and the panel-

ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If a water treatment device has to be
removed from the flange or unscrewed, the
chapter “Intended Use” must always be
observed!
– Protect the flange surfaces from
damage! Damaged flanged surfaces
cannot close tight. As a result, escaping
water can damage the building and
installations.
– Ensure that no dirt can get into the water
treatment device! This dirt can get into
contact with and be discharged into the
drinking water when the water treatment
device is switched back on. The health
of people who drink dirty water is at risk.
– Store the water treatment device in frost-
free conditions! Frost can cause any
water contained in the water treatment
device voids to freeze and thus cause
mechanical damage to the water treat-
ment device so that it leaks at operating
pressure or can burst. Leaking water can
cause major damage to the building. In
addition, people near the water treat-
ment device can be injured by breaking
off water treatment device parts.
– When restarting the water treatment
device, follow the instructions for a new
water treatment device.
