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 le-
gally binding accident prevention provisions
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 tem-
perature 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 de-
scribed in the instruction manual. Any other
or further use is deemed not to be intended
use.
Additional dangers exist in case of non-in-
tended use and failure to observe the dan-
ger 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 in-
struction 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 manu-
al!
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 “Re-
quirements 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 re-
moved as moving parts are a potential dan-
ger!
The range of use for DVGW-tested Soften-
ers 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 Soften-
er is designed so that it can be used to partly
soften all the water for a detached or multi-
ple 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 bars
and 7 bars.
The water pressure must not fall below 2
bars, as otherwise the function can be im-
paired! If the Softener is not regularly regen-
erated, this can result in a pressure loss and
impairment of the softening function.
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
If the water pressure is over 7 bars a pres-
sure reducer must be installed upstream of
the Softener (see Fig. 2). An operating pres-
sure of over 7 bars 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 bars frequently
occur. This can cause damage to important
functional interior parts of the controls. The
optimum operating pressure for the Softener
lies between 3 bars and 5 bars. It works
most economically 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 on “Safety information and
dangers 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 bars to
7 bars we recommend installation
of a pressure 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 15 V, with which the system’s elec-
tronics are operated. Never use any
other power packs.

Product Information
3. Product Information
3.1 Intended purpose
This Softener is suitable for use in cold
drinking water up to a maximum water tem-
perature of 30°C (86°F).
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
Please refer to the chapter on “Intended
Use” for use restrictions.
This Softener is used to protect the water
pipes and hot water heater against limes-
cale 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. technical –scientific
association for the gas and water industries)
in accordance with the requirements of DIN
19636 pressure class PN10 for Softeners
(cation exchangers) in drinking water instal-
lations and are entitled to bear the DIN-
DVGW mark and DVGW-GS mark (see Fig.
3).
3.3 Materials used
The materials used are resistant to the phys-
ical, chemical and corrosive loads to be ex-
pected in the drinking water and fulfil the re-
quirements specified in DIN 19636 (“Soften-
ers (Cation Exchangers) in Drinking Water
Installations”). All materials are hygienically
and physiologically safe. Plastics (KTW rec-
ommendations) and metallic materials fulfil
the requirements of the BgVV (German Fed-
eral Institute for Consumer Health Protec-
tion and Veterinary Medicine).
Limescale deposits inhibit water
flow and can therefore result in in-
creased energy consumption.

4. Installation
4.1 General
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
The unit may only be installed by skilled per-
sonnel.
The chapter on “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 on “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 serv-
icing work.
(see chapter on “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 on “Safety information and
dangers 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 serv-
ice! This enables the water supply to the
Softener to be interrupted during instal-
lation, servicing/maintenance, repairs
and in case of malfunctions. Floods and
serious water damage to house installa-
tions 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!
A power connection (230 V, 50
Hz), which is permanently live,
must be available.

10 JUDO QUICKSOFT-UNO
Installation
4.1.2 Installed position
ATTENTION
(see chapter on “Safety information and
dangers 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
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
A permanent power supply must be availa-
ble. If the Softener is not permanently sup-
plied with electricity
– No regeneration takes place.
– No alarm is given in case of faults.
– Water losses or even water damage can
occur if the power supply is interrupted
during regeneration.
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 Sof-
tener cannot work.
ATTENTION
(see chapter on “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 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.
A splash proof socket is required
for the power pack, in accordance
with the legal regulations for wet
rooms.

4.1.7 Installing the Softener
After flushing the water pipe, remove the as-
sembly cover of the built-in rotary flange.
Remove the white protective disc on the
connecting flange of the Softener by undo-
ing the four M6 Allen screws.
Do not completely unscrew the screws
because of the bayonet connection!
Lift up the Softener and swivel it through ap-
prox. 30° in an anti-clockwise direction. Po-
sition it on the built-in rotary flange so that
the screw heads pass through the bayonet
fixing drill holes (see Fig. 8 I). Swivel the
Softener through approx. 30° back in a
clockwise direction and tighten the four Allen
screws (see Fig. 8 II).
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
(see Fig. 9).
4.1.8 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 wastewater hose with a 10 mm outer di-
ameter may be laid up to 1 m above the unit.
Securely fix the loose end of the hose to the
pipe or similar with the adhesive tape sup-
plied.
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.
If the connection for the wastewater sewer is
higher than this, the salt container can be in-
stalled correspondingly higher with the aid of
a wall bracket (see chapter on “Accesso-
ries”).
ATTENTION
(see chapter on “Safety information and
dangers 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 (6).

Operation
5. Operation
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
Always observe the chapter on “Intended
Use”!
5.1 Commissioning
activate regeneration:
– The Softener is connected to the water
system. The bypass valve is in the "By-
pass" position.
– 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 on “Setting
the required mixed 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 on “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 on “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
on “Setting the blending”).
– Fit the cover (2).
Connect the Softener to the
power supply. Plug the power
pack into the socket.

14 JUDO QUICKSOFT-UNO
Operation
5.1.1 Setting the required mixed wa-
ter 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 on
“Accessories”). If the raw water hardness
fluctuates, set the higher value. Regenera-
tion is always performed with the same
quantity of brine. If the raw water hardness
is high a smaller quantity of water is treated.
If the raw water hardness is low a larger
quantity of water is treated.
The mixed 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 unit digit of the raw water hardness is
set using the DIP switch (21), contacts 1 to
4 (see Fig. 10).
The allocated contact is moved downwards
to make an adjustment.
Example: (raw water hardness 26 °e)
Push contact 2 of the DIP switch (20) and
contact 3 of the DIP switch (21) downwards
(see Fig. 10).
In this case the sum of the tens digit and the
unit digit is 20 °e + 6 °e = 26 °e.
For raw water hardnesses less than 10 °e,
all the DIP switch’s (20) contacts must be
set at the top in the "OPEN" position.
Contact 5 of the DIP switch (21) must be set
at the top in the "OPEN" position.
The controls react to incorrect settings with
an acoustic signal (see chapter on “Faults”).
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 pushed down-
wards.

Operation
5.1.2 Setting the blending
In the factory the setting screw (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 us-
ing measuring equipment (see chapter on
“Accessories”).
The sample water for measurement and ad-
justment of the water hardness can be
drawn off at the bypass valve or at a water
tap downstream of the Softener (see chap-
ter on “Accessories”).
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 Drinking Water Reg-
ulations of 1.1.2003 the limit value for sodi-
um in drinking water is 200 mg/l. This does
not apply to mineral and table water. Their
limit values are considerably higher, some
have values 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 approx. 0.8 bar, 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 on “Safety information and
dangers 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 opera-
tion:
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 hygi-
enically safe condition for weeks after the re-
generating salt shortage occurs.
5.4 Modifications / changes /
spare parts
ATTENTION
(see chapter on “Safety information and
dangers 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
either the control lamp (15) is lit. As soon
as the regeneration is completed trigger
regeneration by pressing on the regen-
eration 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

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 on
“Service Record Sheet”), the customer
service department must be notified. Al-
ways quote the unit number, which is im-
printed in the top of the unit connection
flange (28).
Before carrying out any work on the Soften-
er, which extends beyond pure operational
control, the Softener must be depressu-
rised! Failure to observe this can lead to an
uncontrolled escape of water and therefore
lead to water damage in the building. Strictly
comply with the instructions given in the
“Installation” and “Maintenance” chapters.
5.5 Stoppages
ATTENTION
(see chapter on “Safety information and
dangers 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 on “Commission-
ing”).
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 on “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 on “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 on “Stop-
pages”).

Maintenance
7. Maintenance
ATTENTION
(see chapter on “Safety information and
dangers due to non-compliance”)
Always observe the chapter on “Intended
Use”!
7.1 Cleaning
ATTENTION
(see chapter on “Safety information and
dangers 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 serv-
ice. 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.
