Intended Use
2. Intended Use
Installation and use of the softener are each
subject to the applicable national regula-
tions.
Apart from the instruction manual and the
legally binding accident prevention provi-
sions applicable in the country and place of
use, the recognized technical regulations for
safe and proper work must also be
observed.
The water to be softened must conform
to the European Drinking Water Regula-
tions!
Always contact the manufacturer/supplier
before using water with a different quality or
with additives!
This softener is suitable for use in cold
drinking water up to maximum ambient
temperature of 30 °C (86 °F).
It is produced to state of the art standards
and the generally accepted safety regula-
tions in Germany.
The softener 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 softener outside
the use limitations given in the instruction
manual.
The softeners are only to be used in a tech-
nically 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 safely discharge the
wastewater in operation and in case of any
defect in the system, precise compliance
with the details given in the chapter on
“Requirements for the place of installation”
is necessary!
ATTENTION
(See chapter on “Safety information and
dangers due to non-compliance”)
The used regenerating salt is removed from
the softener columns with the wastewater.
Therefore, it may not be used to water plants
or for similar purposes.
Take extra care if the cover has been
removed as moving parts are a potential
danger!
The range of use for DVGW-tested
softeners is specified in DIN 1988 Part 2
Para. 8.3.2. According to this standard,
there are no restrictions regarding the range
of use for these softeners. The capacity of
the softener is designed so that it can be
used to partly soften all the water for a
detached or multiple dwellings, as well as
corresponding part water quantities for hot
water, swimming pools, washing machines
and dishwashers.

JUDO QUICKSOFT-UNO 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 re-
generated, this can result in a pressure loss
and impairment of the softening function.
ATTENTION
(see chapter “Safety information and dan-
gers 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) fre-
quently occur. This can cause damage to
important functional interior parts of the con-
trols. 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 / installa-
tions
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/equipment
located near the softener must therefore be
splash proof and comply with the legal regu-
lations 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 oper-
ation.
Fig. 2: Pressure reducer upstream of the unit
1
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 ca-
bles 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.

Product Information
3. Product Information
The units conform to the technical regula-
tions for drinking water installations in
accordance with DIN 1988.
3.1 Intended purpose
This softener is suitable for use in cold drink-
ing water up to a maximum water tempera-
ture of 30°C (86°F).
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Please refer to the chapter “Intended Use”
for use restrictions.
This softener is used to protect the water
pipes and hot water heater against lime-
scale deposits.
Partly softened water protects appliances
and fittings and reduces consumption of de-
tergents and cleaning agents.
3.2 Test marks
The units conform to the technical regula-
tions for drinking water installations in ac-
cordance with DIN 1988. They are tested by
the DVGW (Deutsche Vereinigung des Gas-
und Wasserfaches e.V., i.e. the technical-
scientific association for the gas and water
industries) in accordance with the require-
ments of DIN EN 14743 and DIN 19636-100
for softeners (cation exchangers) in drinking
water installations and are entitled to bear
the DIN-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 and fulfil the
requirements specified in the DIN EN 14743
and DIN 19636-100 standards (“Softeners
(cation exchangers) in drinking water instal-
lations”). All materials are hygienically and
physiologically safe. Plastics fulfil the official
guideline of the German Federal Environ-
mental Agency. Metallic materials fulfil the
requirements of the DIN 50930-6 standard
(Impact on the drinking water quality).
Limescale deposits inhibit water
flow and can therefore result in in-
creased energy consumption.

4. Installation
4.1 General
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
The unit may only be installed by skilled per-
sonnel.
The chapter “Intended Use” must always be
observed!
The pipes must be able to safely support the
softener.
Otherwise mechanical damage or fractures/
bursts can occur in the pipes. This can result
in major water damage. People close to the
softener 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 en-
sure convenient operation and servicing
(see chapter “Installed dimensions”)
A clearance of at least 300 mm is required
above the softener in order to be able to
properly carry out all maintenance and ser-
vicing work.
(see chapter “Modifications / changes /
spare parts”)
4.1.1 Requirements for the place of
installation
The room where the unit is installed must
be dry and frost free!
Unauthorised persons must not have ac-
cess to the softener!
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
– The ambient temperature must not ex-
ceed 30°C (86°F)!
– In order to be able to safely discharge
the wastewater (regeneration) in opera-
tion and in case of any defects that occur
in the system, precise compliance with
the details given in the “Installation”
chapter is necessary!
– If the wastewater cannot be safely and
completely discharged, the house and
installations can be damaged by water.
– A shut-off valve must be installed up-
stream and downsteam of the softener
with a bypass to allow continued water
supply when the softener is out of ser-
vice! This enables the water supply to
the softener to be interrupted during in-
stallation, servicing/maintenance, re-
pairs and in case of malfunctions. Floods
and serious water damage to house in-
stallations can therefore be avoided.
– The unit can be installed in all standard
drinking water pipes.
– It is not permitted to install the softener
upstream of the water meter!
4.1.2 Installing position
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Always install the softener in a vertical posi-
tion (± 5°)!
Failure to observe this can impair its func-
tion.
4.1.3 Power supply
A power connection (230 V, 50
Hz), which is permanently live,
must be available.
A splash proof socket is required
for the power pack, in accordance
with the legal regulations for wet
rooms.

10 JUDO QUICKSOFT-UNO
Installation
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
The mains voltage may not be interrupted
(e. g. by light switches). If the power supply
is interrupted during regeneration,
– no regeneration takes place.
– no alarm is given in case of faults.
– water losses or even water damage can
occur.
4.1.4 Mounting the built-in rotary
flange
The built-in rotary flange is used as a con-
necting element between the pipe and the
softener.
It is suitable for both horizontal and vertical
pipes.
The installation height depends on the pipe
layout. The minimum installation height from
the floor to the rotary flange is 40 cm.
The built-in rotary flange must be in-
stalled in the direction of flow. This is
marked by a cast in arrow (see Fig. 4).
Failure to comply with this means the soften-
er cannot work.
ATTENTION
(see chapter “Safety information and dan-
gers 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 so that
mechanical stresses cannot occur! Other-
wise mechanical damage can result in the
built-in rotary flange. This can result in major
water damage.
In this case, people close to the softener are
exposed to a health risk due to the large
quantities of water.
Therefore, during installation, ensure that no
large forces act on the pipe, built-in rotary
flange and softener.
4.1.5 Fitting the wall support

4.1.6 Assembling the softener with-
out a bypass valve
– At first flush the pipe with the newly
installed bypass valve (JQE) and shut off
the water supply.
– After flushing the water pipe take off the
assembly cover of the built-in rotary
flange.
The connection flange of the softener is
covered by a white protective disc. This pro-
tective disc is fastened with four cylinder
head screws M6x25.
– Loosen all four cylinder head screws
M6x25, but don’t remove them (bayonet
fixture)!
– Remove the white protective disc.
ATTENTION
Do not grasp into the connection flange
of the device after removing the white
protective disc (danger of violent pres-
sure)!
The section of the profiled flange gasket
must point towards the Built-in rotary flange.
Failure to observe this can lead to leaks and
water escaping. This can in turn cause water
damage to the house and its installations.
– Lift up the softener and swivel it through
approx. 30° in an anti-clockwise direction.
– Position it on the bulit-in rotary flange so
that the screw heads pass through the
bayonet fixing drill holes (see Fig. 7 I).
– Swivel the softener through approx. 30°
back in a clockwise direction.
– Tighten the four cylinder head screws
M6x25 (see Fig. 7 II).
After assembling the softener unscrew the
wall support so far that it rests against the
softener casing and the softener hangs
vertically to the wall.
4.1.7 Assembling the bypass valve
(accessories)
By assembling a bypass valve between the
built-in rotary flange and the softener a
bypass piping becomes redundant.
– At first flush the pipe with the newly
installed bypass valve (JQE) and shut off
the water supply.
– After flushing the water pipe take off the
assembly cover of the built-in rotary flange.
– Connect the bypass valve on the flange
side with the cast in letter "R" (pipe

The hand-wheel of the bypass valve can be
positioned anywhere above the unit or to the
side. Depending on conditions on site,
installation should be carried out ensuring
sufficient access to the hand-wheel.
4.1.8 Assembling the softener to
the pre-assembled bypass
valve
The connection flange of the softener is
covered by a white protective disc. This pro-
tective disc is fastened with four cylinder
head screws M6x25.
– Loosen all four cylinder head screws
M6x25, but don’t remove them (bayonet
fixture)!
– Remove the white protective disc.
ATTENTION
Do not grasp into the connection flange
of the device after removing the white
protective disc (danger of violent pres-
sure)!
The section of the profiled flange gasket
must point towards the bypass valve. Failure
to observe this can lead to leaks and water
escaping. This can in turn cause water dam-
age to the house and its installations.
– Lift up the softener and swivel it through
approx. 30° in an anti-clockwise direction.
– Position it on the flange of the bypass
valve marked with the cast in letter "G"
(unit flange) so that the screw heads
pass through the bayonet fixing drill
holes.
– Swivel the softener through approx. 30°
back in a clockwise direction.
– Tighten the four cylinder head screws
M6x25.
After assembling the softener unscrew the
wall support so far that it rests against the
softener casing and the softener hangs
vertically to the wall.
4.1.9 Wastewater connection and
back-up overflow hose
The hoses for the regeneration wastewater
and the back-up overflow must both be laid
up to the wastewater sewer without any
kinks. Ensure free discharge above the
wastewater channel or floor drain.
The waste water hose with 10 mm of outside
diameters may not be shifted more highly
than the control actuator. The tube length
may amount to maximally 3 m. Securely fix
the loose end of the hose to the pipe or
similar with the adhesive tape supplied.
The back-up overflow hose with a 19 mm
outer diameter must be laid with a constant
fall to the wastewater sewer and free of
kinks.

Operation
If the connection for the wastewater sewer is
higher than this, the salt container can be
installed correspondingly higher with the aid
of a wall bracket (see chapter “Accesso-
ries”).
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
The wastewater connection must not be lo-
cated above the softener.
An adequately dimensioned wastewater
connection (e.g. floor drain) to DIN 1986
must be available for the wastewater and
the back-up overflow hose.
5. Operation
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Always observe the chapter “Intended Use”!
5.1 Commissioning
The softener is connected to the water
system. The bypass valve is closed so that
the water by-passes the softener.
– Fill the regeneration salt into the salt
container (5). The water dissolves the
regeneration salt producing saturated
brine. The regeneration salt must at
least conform to food quality standards
and should fulfil the requirements ac-
cording to DIN EN 973.
–Our recommendation: Broxo or Solvay
salt, either as a block, tablets or coarse
grains 7 - 15 mm. If you use other regen-
erating salts, the salt container (5) must
be cleaned at shorter intervals and the
intake screen (88) replaced more often.
– Pour approx. 4 litres of water into the salt
container (5).
– Remove the cover (2).
– Enter the installation date on the label of
the operating cylinder (36) and in the
“servicing record sheet”.
– Set the raw water hardness (°e) at the
electrical circuit (see chapter “Setting the
raw water hardness”).
– Open the water inlet. Open the bypass
valve.
ATTENTION
For safety reasons the softener must be
vented immediately after it is connected to
the water system (bypass valve is open).
The system is automatically vented during
the first regeneration (see chapter “Com-
missioning”).
– After each connection to the power sup-
ply the electronics automatically perform
a self-test for approx. 10 seconds. After
this has been successfully completed all
the control lamps briefly light up The sys-
tem control lamp (13) then lights up.
– Trigger regeneration manually: Press
the regeneration trigger (18). At the
same time you can check whether the
system is functioning correctly (see
chapter “Servicing/Repair”).
After completing the regeneration the
softener is ready for use (approx.9 min-
utes).
The intake time should be at least 30
seconds (digit 2 can be seen on the driv-
ing wheel (11)). If the intake time is
shorter, water must be poured into the
salt container (5). Filled level 10 – 11 cm
above the floor of the container. Start a
new regeneration and check the intake
time.
– Mix in hard water using the setting screw
of the blending valve (10) (see chapter
Connect the softener to the
power supply. Plug the power
pack into the socket.

14 JUDO QUICKSOFT-UNO
Operation
“Setting the blending”).
– Fit the cover (2).
5.1.1 Setting the raw water
hardness
The value depends on the place of installa-
tion. You can ask the responsible water-
works or determine it using suitable measur-
ing equipment (see chapter “Accessories”).
If the raw water hardness fluctuates, set the
higher value. Regeneration is always per-
formed with the same quantity of brine. If the
raw water hardness is high a smaller quanti-
ty of water is treated. If the raw water hard-
ness is low a larger quantity of water is treat-
ed.
The raw water hardness is set using the
DIP switches (20 and 21).
The tens digit of the raw water hardness is
set using the DIP switch ( 20 ), contacts 1 to 8.
The units digit of the raw water hardness is
set using the DIP switch ( 21 ), contacts 1 to 4
(see Fig. 10).
To make an adjustment the allocated
contact of the DIP switch is moved to the
position opposite to „ON“.
For raw water hardnesses less than 10 °e,
all the DIP switch’s (20) contacts must be
set in the „ON“ position.
Contact 5 of the DIP switch (21) is moved to
the position „ON“.
The controls react to incorrect settings with
an acoustic signal (see “Faults” chapter).
The country to be set is adjusted using the
DIP switch (21), contacts 6 to 8.
To set the English hardness the contact 8 of
the DIP switch (21) is moved to the position
opposite to „ON“.
Example: (raw water hardness 26 °e)
– Push contact 2 of the DIP switch (20)
and contact 3 of the DIP switch (21) into
the position opposite to „ON“ (see Fig.
9).
– In this case the sum of the tens digit and
the units digit is 20 °e + 6 °e = 26 °e.

Operation
5.1.2 Setting the blending
In the factory the setting screw of the blen-
ding valve (10) is set to the “Soft” position.
You first have to check what the mixed water
hardness is with this setting. The water
hardness is measured using measuring
equipment (see chapter “Accessories”).
The sample water for measurement and ad-
justment of the water hardness can be
drawn off at the bypass valve (see chapter
“Accessories”) or at a water tap downstream
of the softener.
Ensure that the readjusted mixed water has
reached the drawing off point from the sof-
tener. To correctly compare the measured
values, the samples should be taken from a
normal water flow (1 tap fully opened). Dur-
ing the drawing off no large water quantities
may be drawn off at any other point.
If the required mixed water hardness has
still not been reached, it can be achieved by
turning the blending (10). Recommended
hardness is approx. 10°e.
The setting may have to be changed and re-
measured several times before the required
value is reached.
The softening increases the sodium concen-
tration in the mixed water, depending on the
raw water hardness and the mixed water
hardness set.
In accordance with the current drinking wa-
ter regulations the limit value for sodium in
drinking water is 200 mg/l. This does not ap-
ply to mineral and table water. Their limit val-
ues are considerably higher, some have val-
ues above 1000 mg of sodium per litre.
If the calculated total sodium content ex-
ceeds the value permitted under the Drink-
ing Water Regulations of 200 mg/l, it can be
corrected by increasing the mixed water
hardness accordingly. The sodium content
must be recalculated.

5.2 Functional description
The softener is a single column system, i.e.
there is a filter case with ion-exchange resin
beneath the control head. Therefore, this
softener has a very compact design. The
ion-exchange resin in the filter case consists
of small synthetic resin spheres, at which
the calcium and magnesium ions, which
make the water "hard", are exchanged for
sodium ions. This makes the water "soft". An
adjustable quantity of unsoftened raw water
is added to the control head in order to ob-
tain the required mixed water hardness
downstream of the softener.
However, the ion-exchange resin only ab-
sorbs a limited quantity of hardness constit-
uents. Depending on the water hardness,
sooner or later it is exhausted. A water me-
ter installed in the soft water pipe precisely
records the quantity of soft water produced
and triggers regeneration according to the
raw water hardness set at the electronics.
The regeneration is carried out with eco-
nomic salt used according to DIN 19636.
Here diluted brines (sodium chloride) are
used to remove the hardness constituents
from the resin again.
With the regeneration the system is also
regularly disinfected, in order to prevent
contamination with germs. The small quanti-
ty of chlorine required for this is electrolyti-
cally generated during regeneration from
the drawn in brine.
Regeneration automatically takes place
through wear free ceramic disc valves. The
regeneration sequence is fixed by the geom-
etry of the discs and therefore does not have
to be re-entered even in case of a power fail-
ure.
For design reasons, only untreated water is
available during regeneration, to this end an
overflow valve integrated in the control head
opens when required. As the whole regener-
ation including rinsing out the used brine on-
ly takes around 9 minutes, this typical prop-
erty of a single column system is hardly
noticeable.

Operation
If the pressure loss in the softener system is
larger than 1.0 bar (14.5 psi), the overflow
valve integrated in the control head opens.
The open overflow valve reduces the pres-
sure loss by diverting the hard water around
the softener system.
The pressure loss provision increases the
mixed water hardness downstream of the
hardness system for a short time die. During
regeneration the water drawn from the tap
flows through the overflow valve.
5.3 Salt fill
As the softener functions automatically, you
only have to refill it with regeneration salt
from time to time.
At the latest when the “Top up salt” sticker
becomes visible in the salt container.
The salt stocks should not be allowed to re-
duce so much that the liquid level is above
the regenerating salt, otherwise it rises ex-
cessively when the salt is refilled. The liquid
level should be 10 - 12 cm above the floor of
the container.
If the container is not refilled in good time the
solid regenerating salt displaces the brine.
An unnecessarily large amount of brine is
drawn up during the next regeneration, the
intake procedure takes a correspondingly
longer time.
Our recommendation: Broxo or Solvay
salt, either as a block, tablets or coarse
grains 7 - 15 mm.
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
If there is no more regenerating salt in the
container or if it is not refilled in good time,
the softener switches to economy operation:
The brine stocks still available are primarily
used for disinfecting the ion exchange resin
and the softening effect is reduced.
In this way, the softener remains in a hygien-
ically safe condition for weeks after the re-
generating salt shortage occurs.
5.4 Modifications / changes /
spare parts
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Only original spare parts are to be used!
Independent modifications and changes are
prohibited for safety reasons! These can im-
pair the function of the softener. The test
marks imprinted on the unit are only valid if
original spare parts are used.
5.4.1 Servicing/Repair
The unit must be serviced at least once a
year in accordance with the requirements of
DIN 1988. A half-yearly service is required
for jointly used systems.
We recommend you conclude a servicing
agreement.
Check the functions:
– Remove the cover (2).
– As long as regeneration is taking place
the control lamp (15) is lit. As soon as the
regeneration is completed trigger rege-
neration by pressing on the regenera-
tion trigger button (18).
– The driving piston turns the driving
wheel (23), which in turn controls the
small gear wheel. Each stroke of the
driving piston is accompanied by the
lighting up of the LED (14). The position
of the driving wheel can be read off at the
position display (11). After two strokes
the salting position (Pos 2) is reached.
After approx. 3 minutes the drive exe-
cutes a stroke again. Wastewater quan-
tity up until then approx. 3.5 litres.
– After this stroke the "Backwash" position

18 JUDO QUICKSOFT-UNO
Operation
(Pos 3) is reached. The resin is flushed
from below upwards. Duration 100 sec-
onds, wastewater 3 – 4.5 litres.
– Then two strokes are performed again,
until the "Initial Filtrate" position (Pos 5)
is reached. Here the resin is flushed
from above downwards. Duration 100
seconds, wastewater 2.5 -4 litres.
– After two further strokes the regenera-
tion is completed. Total duration max. 9
minutes.
– If the measured values significantly differ
from the setpoint values (see chapter
“Service Record Sheet”), the customer
service department must be notified. Al-
ways quote the unit number (28), which
is imprinted in the top of the unit connec-
tion flange.
Before carrying out any work on the soften-
er, which extends beyond pure operational
control, the softener must be depressurised!
Failure to observe this can lead to an uncon-
trolled escape of water and therefore lead to
water damage in the building. Strictly com-
ply with the instructions given in the
“Installation” and “Maintenance” chapters.
5.5 Stoppages
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
The water supply to the softener is interrupt-
ed. The main tap is closed or the bypass
valve is switched over.
The softener must be stored in a dry, frost-
free place when dismantled. The connecting
flange must be protected against dirt and
damage.
If the softener is refitted and put back into
service, regeneration must always be car-
ried out first (see chapter “Commissioning”).
Disconnect the power pack from
the socket! (If installed, disconnect
the power pack of the downstream
metering pump too!)

Faults
6. Faults
In order to ensure unit safety and leak
tightness, only approved persons may
open the units and replace parts subject
to water pressure.
At the start of the regeneration a timing ele-
ment of around 5 hours is started. If the re-
generation is not completed within this time
an error message is triggered. The occur-
rence of a fault in the unit is signalled by an
intermittent buzz.
Deleting the error message:
Disconnect the power pack from
the socket. Plug it back in after ap-
prox. 5 seconds!
Help with faults:
Fault Cause Remedy
Fault message Temporary failure of the
pipe pressure!
– Delete fault signal.
– Trigger regeneration manually (see
chapter “Commissioning”).
Late salt refill.
During regeneration the
driving wheel was man-
ually turned.
The drive turns the driving wheel until the
normal operating position is reached again.
Then the red control lamp goes out and the
softener is again ready for use.
Operating error e.g. in
the hardness setting.
Reset the DIP switch (see chapter “Com-
missioning”).
Renewed fault
signal after delet-
ing the fault signal
5 hours ago!
With bypass facility:
– Set to bypass!
– Disconnect the power pack from the
socket! (If installed, disconnect the pow-
er pack of the downstream metering
pump too).
– Immediately notify the fitter or nearest
customer service.
Without bypass facility:
– Disconnect the power pack from the
socket! (If installed, disconnect the pow-
er pack of the downstream metering
pump too).
– Immediately notify the fitter or nearest
customer service (see chapter “Stoppag-

Maintenance
7. Maintenance
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Always observe the chapter “Intended Use”!
7.1 Cleaning
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Only use clear, clean drinking water to
clean the housing.
Domestic all-purpose cleaners and glass
cleaners can contain up to 25% solvents or
alcohol (spirits).
These substances can chemically attack the
plastic parts, which can lead to brittleness or
even fractures.
Such cleaners must therefore not be
used.
8. Warranty and Services
In order to comply with the legal warranty
claim, according to DIN 1988, Part 8, it is
necessary that the owner/user “carry out an
inspection at least every 2 months.” De-
pending on the water volume consumed, the
corresponding salt consumption must be
regularly monitored. If necessary refill the
regenerating salt (only use quality according
to DIN EN 973). Hygienic care is required
when refilling salt. For example, the salt
packages should be cleaned before use so
that contaminations cannot get into the salt
solution container. The regenerating salt
must be tipped directly from the opened
package into the salt solution container. En-
sure that the salt solution container is not
overfilled and that it is carefully closed again
at the end of the work. Part packages are to
be avoided. The salt may only be stored in
clean and dry rooms. A service is to be car-
ried out by a qualified, skilled service firm of
the manufacturer …“at least”… annually,
half-yearly in jointly used installations …”.
Regular servicing is indispensable in order
to continue to achieve a successful process
for many years after the unit is put into ser-
vice. In the building services sector this is
covered by DIN 1988, Part 8.
A servicing agreement is the best way to en-
sure a good operating function beyond the
warranty period.
Wherever possible, the regular servicing
work and supply with consumables and
wearing materials, etc. should be carried out
by the specialist trade or the factory’s cus-
tomer service department.
The service-label fixed to the device
should be marked by the plumber after
the mounting of the device and indicates
the date of the service that will take place
next.
