Intended use
2 Intended use
Both installation and use of the water soften-
ing system are subject to the applicable na-
tional regulations.
Alongside the operating instructions, the le-
gal regulations applicable in the country and
place of use in respect of accident preven-
tion, the recognised technical regulations for
safe and professional work must be ob-
served.
The water to be softened must comply
with the European Drinking Water Direc-
tive!
The manufacturer/supplier must be consult-
ed before using water of a different quality or
water with additional additives!
The water softening system is suitable for
use in cold drinking water up to a maximum
ambient temperature of 30 °C.
It is manufactured according to the state of
the art and recognised German safety regu-
lations.
The water softening system may only be
used as described in the operating instruc-
tions. Any other use or use beyond the spec-
ified use is considered to represent incorrect
use.
Additional dangers exist in the event of incor-
rect use and in the event of non-observation
of the danger symbols and safety instructions.
The manufacturer/supplier shall not be re-
sponsible for any resulting damage. All risks
are borne solely by the user.
Intended use includes observance of the op-
erating instructions.
The manufacturer/supplier must be consult-
ed before using the water softening system
outside the limits of use described in these
operating instructions.
The water softening system must only be
used as intended in a technically fault-free
state, while maintaining safety and hazard
awareness, and in compliance with the oper-
ating instructions.
Ensure that malfunctions are rectified
immediately!
So that the waste water can be safely
drained away both during operation and also
in the event of a possible system defect, the
specifications given in chapter 4.1.1 “Requi-
rements for the place of installation” must be
closely observed!
ATTENTION
(see chapter 1.2 “Safety instructions and
dangers due to non-observation”)
The spent regenerating salt is removed from
the water softening columns together with
waste water. Therefore it must not be used
for irrigation or similar purposes.
The application range is specified in DIN EN
806-2 and DIN 1988-200 for DVGW ap-
proved water softening systems. In accord-
ance with the standard, there are no limita-
tions in respect of the area of use for this
water softening system. The designed ca-
pacity of the water softening system is such
that it is capable of partially softening the en-
tire water requirement for a single or multiple
family house as well as corresponding partial
water quantities for hot water, swimming
pool, washing machine and dishwasher.
2.1 Water pressure
The water pressure must be between 2 bar
and 7 bar.
The water pressure must not exceed 2 bar
as otherwise the function can be impaired! If
the water softening system is not regularly
serviced, the softening function can be im-
paired.

Intended use
ATTENTION
(see chapter 1.2 “Safety instructions and
dangers due to non-observation”)
Where the water pressure is greater than
7bar, a pressure reducer must be installed
upstream of the water softening system
(see fig. 2)
. An operating pressure greater
than 7 bar can result in malfunctions.
The optimum operating pressure for the wa-
ter softening system is between 3 bar and
5 bar. This is where it operates most eco-
nomically.
2.2 Indication of particular dan-
gers
2.2.1 Electrical devices/installations
Electrical devices/installations that are not
splash-proof and are located in the vicinity of
the water softening system may be dam-
aged by water that escapes during regener-
ation or in the event of incorrect use of the
water softening system. If the electrical de-
vices/installations are connected to the pow-
er supply, it is also possible that a short-cir-
cuit could occur. Should this occur there is a
risk of electric shocks to people. Therefore
electrical devices/furnishings and equip-
ment in the vicinity must be splashproof and/
or comply with the legal regulations for wet
areas.
ATTENTION
(see chapter 1.2 “Safety instructions and
dangers due to non-observation”)
Caution when touching without the cover!
During operation, electronic components
can become hot. Also there is a danger due
to moving parts.

Product information
3 Product information
3.1 Application
The water softening system is suitable for use
with cold drinking water having a maximum
water temperature of up to 30 °C.
ATTENTION
(see chapter 1.2 “Safety instructions and
dangers due to non-observation”)
Usage limitations see chapter 2 “Intended
use”.
This water softening system is for protection
of water pipes and the water heater against
limescale deposits.
With partially softened water, devices and fit-
tings are preserved and the consumption of
washing and cleaning agents reduced.
3.2 Approval marks
The devices comply with the technical regu-
lations for drinking water installation accord-
ing to DIN EN 806 ff. and the national sup-
plement DIN 1988 ff. as well as DIN EN
1717. They are designed in accordance with
DIN EN 14743 and DIN 19636-100. The
DIN-DVGW marking is applied for.
3.3 Materials used
The materials used are resistant to the phys-
ical, chemical and corrosive loads expected
to be encountered in drinking water and fulfil
the specifications required by DIN EN
14743 and DIN 19636-100 (“Water soften-
ing systems (cation exchangers) in drinking
water installations”). All materials are hy-
gienically and physiologically harmless.
Plastics fulfil the KTW Guideline (Guideline
for the Hygienic Assessment of Organic Ma-
terials in Contact with Drinking water) of the
German Federal Environmental Agency
(UBA). Metallic materials fulfil the require-
ments of DIN 50930-6 (Effect of metallic ma-
terials on the quality of drinking water).
4 Installation
4.1 General
ATTENTION
(see chapter 1.2 “Safety instructions and
dangers due to non-observation”)
Installation must only be performed by suitably
qualified technical personnel.
Chapter 2 „Intended use“ must be observed
without fail!
The pipe must be able to safely support the
water softening system.
Otherwise mechanical damage to the pipe
up to and including breaks can result. This
can result in severe water damage. Persons
in the vicinity of the water softening system
are exposed to a risk of injury or harm be-
cause of the large water volumes that could
escape. For this reason pipes must, where
necessary, be provided with additional fas-
tenings or support.
To ensure convenient operation and mainte-
nance always adhere to the specified di-
mensions and distances (see chapter 9.4
“Installation dimensions”).
At least 300 mm clearance is required above
the water softening system, so that all main-
tenance work can be properly performed.
Limescale deposits block the water
supply and therefore can result in in-
creased energy consumption.

10 JUDO QUICKSOFT-P
Installation
4.1.1 Requirements for the place of
installation
– The ambient temperature must not ex-
ceed 30 °C!
– So that it is possible to safely drain the
waste water (regeneration) during oper-
ation and also in the event that a system
defect occurs, the specifications given in
chapter 4 “Installation” must be precisely
followed!
If the waste water cannot be safely and
completely drained, it is possible that
property damage to the home and fur-
nishings may be caused by the water.
– A shut-off valve must be installed up-
stream of the water softening system if
no bypass valve (JQX) is fitted. This al-
lows the water supply to be disconnect-
ed for water softening system mainte-
nance, repairs or in case of malfunction.
– The installation room must be dry and
free from frost. Unauthorised persons
must not be able to access the water sof-
tening system.
– The water softening system must not be
subject to severe impacts.
– The device can be installed in all com-
mercially available drinking water pipes.
– Installation of the water softening system
upstream of the water meter is forbid-
den!
4.1.2 Mounting orientation
4.1.3 Power supply
The mains voltage must not be interrupt-
ed (e.g. via a light switch).
If the water softening system does not have
a permanent power connection,
– Regeneration will not take place,
– No fault warnings will be output.
– Water leakage or even water damage
may occur during a regeneration as a re-
sult of a loss of power.
4.2 Installation of the rotary flange
fitting (JQE)
The rotary flange fitting serves as a connect-
ing piece between the pipe and the water
softening system.
It is suitable both for horizontal and vertical
pipes.
The installation height depends on the pipe
course. The minimum installation height
measured from the ground to the middle of
the pipe is 52 cm.
The rotary flange fitting must be installed
in the direction of flow. This is indicated
by an arrow integral with the casting (see
fig. 3).
To ensure fault-free operation, ob-
serve the following requirements:
A permanent power connection
(230 V, 50 Hz) must be available.
Always install the water softening
system in an upright position (±
5°)! If this is not observed, incor-
rect functioning may result.
A splash-proof socket, complying with
the legal regulations for wet areas, is
required for the power supply unit.
Fig. 3: Rotary flange fitting
If this requirement is ignored, the
water softening system will not
work.

JUDO QUICKSOFT-P 11
Installation
The flange surface of the rotary flange fitting
must be upright! The rotary flange fitting
must be fitted so that it is free from mechan-
ical stress or strain. Otherwise mechanical
damage of the rotary flange fitting may re-
sult. This can result in severe water dam-
age.
Therefore when installing, ensure that no
large forces act on the pipe, rotary flange fit-
ting or water softening system.
4.3 Installing the wall support components
The wall support ensures safe support of the device and in this way prevents rotation of the
device around the pipe. The mounting of the wall support (order no. 2201397) is described
in more detail in the corresponding installation instructions.
The bracket set (order no. 2201396) is primarily for relieving and securing the pipe.
4.4 Installation of the water sof-
tening system without a by-
pass valve
– First flush the pipe with the newly in-
stalled rotary flange fitting JQE. The ro-
tary flange fitting is still sealed by the
black mounting cover.
– Then shut-off the water again (at the
stopcock or shut-off valve) and remove
the mounting cover of the rotary flange
fitting.
The connection flange of the water softening
system is covered by a white protective cap.
This protective cap is secured using four
hexagon socket head screws M6×130.
– Loosen all four hexagon socket head
screws M6×130, but do not screw out
completely (bayonet connection)!
– Remove the white protective cap.
The profile of the profile flange seal must
point towards the rotary flange fitting (see
fig. 5). If this is not observed, the sealing

Installation
may not be perfect resulting in water escap-
ing. This could result in water damage to the
home and furnishings and equipment.
– Raise the water softening system and
swivel approximately 30° in an anti-
clockwise direction.
– Place on the rotary flange fitting so that
the screw heads project through the bay-
onet holes (see fig. 6 I).
– Swivel the water softening system back
approximately 30 ° in a clockwise direc-
tion.
– Fully tighten the four M6×130 hexagon
socket head screws (see fig. 6 II).
After installation of the water softening sys-
tem, screw out the wall support until it touch-
es the cladding of the water softening sys-
tem and the device hangs vertically on the
wall.
4.5 Installation of the bypass
valve (accessories)
If a bypass valve is used between the rotary
flange fitting and the water softening system
it will remain possible to continue to draw a
supply of untreated drinking water during
possible maintenance on the system.
– First flush the pipe with the newly in-
stalled rotary flange fitting JQE. The ro-
tary flange fitting is still sealed by the
black mounting cover.
– Then shut-off the water again (at the
stopcock or shut-off valve) and remove
the mounting cover of the rotary flange
fitting.
– Connect the bypass valve with the rotary
flange fitting, by engaging the bayonet,
on the flange side with the cast-in letter
“R” (R=Rohr [pipe]) (see fig. 7).
– Fully tighten the four M6×25 hexagon
socket head screws.
The handwheel of the bypass valve can ei-
ther project vertically upwards or to the side.
Installation should be performed so that, de-
pendent on local circumstances, the
handwheel can be easily accessed.

not reach into the device connection flange
(risk of crushing)!
– Loosen all four hexagon socket head
screws M6×130, but do not screw out
completely (bayonet connection)!
– Remove the white protective cap.
The profile of the profile flange seal must
point towards the bypass valve. If this is not
observed, the sealing may not be perfect re-
sulting in water escaping. This could result
in water damage to the home and furnish-
ings and equipment
– Raise the water softening system and
swivel approximately 30° in an anti-
clockwise direction.
– Position the water softening system on
the ‘G’-labelled flange of the bypass
valve so that the screw heads project
through the bayonet holes (see fig. 6 I).
– Swivel the water softening system back
approximately 30° in a clockwise direc-
tion.
– Fully tighten the four M6×130 hexagon

– Fill 25 - 50 kg of regenerating salt into
the salt reservoir.
The regenerating salt must as a minimum
comply with the requirements of DIN EN 973
and be of food-grade.
Our recommendation: Broxo or Solvay
salt, either as blocks, tablets or coarse
grains 7 - 15 mm. If other regenerating salts
are used, then the salt reservoir must be
cleaned at shorter intervals and the intake
strainer replaced more frequently.
– Remove the cover.

tem must be immediately flushed and re-
generated for venting.
See chapters 5.3.1 and 5.3.2 for this pur-
pose!
5.3.1 Flushing the water softening
system
– To do so open a tap (as close as possi-
ble to the water softening system) and
create a volume flow of about 500 l/h.
– After a minute’s flushing (both resin con-
tainers are vented), plug the power sup-
ply unit into the socket.

The water softening system is now ready for
operation.
The following parameters must then be set:
– Raw water hardness (see chapter 5.3.3
“Setting the raw water hardness”)
– Mixing (see chapter 5.3.4 “Adjusting the
mixing”)
5.3.3 Setting the raw water hard-
ness
The value depends on the installation loca-
tion. It can either be requested from the wa-
ter supply company or determined using a
suitable measuring instrument (in the scope
of supply). If the raw water hardness fluctu-
ates, the higher value should be set. The
same quantity of brine is always used for re-
generation. If the raw water hardness is
high, a reduced water volume is treated. If
the raw water hardness is low, a greater wa-
ter volume is treated.
The water softening system is pre-set to a
raw water hardness of 25 °e. Another raw
water hardness is set as follows:
Press key . The display indicates the fol-
lowing:
Press the <OK> key. The display indicates
the following:
Press the <OK> key. The display indicates
the following:
Use the key to reduce the raw water
hardness and the key to increase the
hardness. The step size is 1 °e.
The set raw water hardness value is saved
by pressing <OK>.
5.3.4 Adjusting the mixing
In the factory the set screw of the mixing
valve is set to slightly open (see fig. 13).
First a check must be performed to deter-
mine what mixing water hardness exists with
this setting. The water hardness measure-
ment is performed with a measuring instru-
ment (in the scope of supply).
The sample water for measuring and setting
the water hardness can be drawn at the by-
pass valve or from a water tap connection
downstream of the water softening system.
It must be ensured that the set mixing water
hardness in the water softening system
reaches the drawing point. For a correct
measuring value comparison, the samples
should be taken with a normal water flow

(one tap fully open). During drawing, no
large volume of water should be drawn at
another point.
If the desired mixing water hardness is not
achieved, then it can be corrected by turning
the set screw of the mixing valve within the
marked adjustment range by no more that
one half turn. A value of about 10 °e is re-
commended.
If necessary, the setting must be changed
and re-measured a number of times until the
desired value is achieved.
After the softening, the sodium concentra-
tion in the mixing water increases, depend-
ent on the raw water hardness and the set
mixing water hardness.
According to current drinking water legisla-
tion, the limit value for sodium in drinking
water is 200 mg/l. Mineral and table water
are not affected by this. Their limit values
are much higher, partially greater than 1000
mg sodium per litre.
If the calculated total sodium content ex-
ceeds the valve permitted by the drinking
water legislation of 200 mg/l, then it can be
corrected by increasing the mixing water
hardness.
The calculation of the sodium content must
then be repeated.
