Intended use
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!
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 designed capacity of the water softening
system is such that it is capable of partially
softening the entire water requirement for a
single or multiple family house as well as cor-
responding partial water quantities for hot
water, swimming pool, washing machine and
dishwasher.
2.1 Indication of particular dan-
gers
2.1.1 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.
Caution when touching without the cover!
During operation, electronic components
can become hot. Also there is a danger due
to moving parts.
Potential-free output
Switching voltage............. maximum 24 V
Current ................................ maximum 1 A
(see chapter 5.7 “Potential-free fault indica-
tion”)
No electrical cables and equipment
may be located below or in the im-
mediate vicinity of the water soften-
ing system!
In the power supply unit the mains
voltage is reduced to a safe low volt-
age of 24 V which is then used to op-
erate the system electronics. No oth-
er power supply units must be used.
Only low voltages can be used for
the remote transmission of the fault
indication via the potential-free out-
put!

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
fittings are preserved and the consumption
of washing and cleaning agents reduced.
3.2 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
All information required for installation is
contained in the installation instructions
1703525 for the QUICKSOFT MEGA 6 wa-
ter softening unit.

(see fig. 8)
– Fill approximately 5 litres of water into
the salt reservoir (4),until just above the
intermediate bottom.
– 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.
– Enter the date of installation on the label
(see fig. 3).
– Open the water supply (stopcock or
shut-off valve).
– Ensure that the bypass valve (if in-
stalled) is set to “Operate”.
ATTENTION
For safety reasons, the water softening sys-
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.
After connection to the power supply, the
electronics automatically perform a self-test.

Operation
5.3.2 Manually starting regeneration
of the water softening system
manual
To do so, the water softening system must
be in an operating situation. The status dis-
play is output to the display (see fig. 4).
Press key 1x and then key 1x. The
display indicates the following:
Press the <OK> key. The display indicates
the following:
Pressing <OK> starts regeneration.
Then ‘Regeneration’ is output to the display.
Regeneration is completed after about 15
minutes. The status display is output again
(see fig. 4).
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. 5). First
a check must be performed to determine
what mixing water hardness exists with this
setting. The water hardness measurement
is performed with a measuring instrument (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

Operation
(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.

Operation
5.5 Function description
5.5.1 Method of operation
The filter containers are filled with ion-ex-
change resin. This comprises small plastic
resin balls on which the calcium ions, which
make the water ‘hard’, are exchanged for
sodium ions. Consequently the water be-
comes soft. In the control head an adjusta-
ble quantity of not-softened raw water is ad-
mixed to obtain the desired mixing water
hardness downstream of the system. How-
ever the ion-exchange resin only absorbs a
limited quantity of these hardness compo-
nents. Dependent on the water hardness
and the treated water volume, sooner or lat-
er it is exhausted. The time at which it be-
comes exhausted is measured with the wa-
ter meter and regeneration automatically
triggered. To do so, diluted brine (sodium
chloride) is used to remove the hardness
components from the resin.
5.5.2 System design
The water softening system is designed as a
parallel system that is regenerated in two
stages. During regeneration, the two resin
containers are alternately responsible for
soft water provision. In this way soft water is
always available for the consumer, even
during regeneration.
5.5.3 Regeneration
With a very short regeneration period of
about 7.5 minutes per resin container (total:
15 minutes) high volume continuous draw-
ing is possible.
The soft water volume is precisely meas-
ured using a water meter in the system’s soft
water pipe and in this way triggering of re-
generation is controlled. Regeneration is
performed according to DIN EN 14743 and
DIN 19636-100 using miser salting. Disin-
fection of the system takes place at regular
intervals to prevent microbe contamination.
The small quantity of chlorine required for
this is created electrolytically during regen-
eration from the absorbed brine.
5.5.4 Control of regeneration
Regeneration is performed automatically via
wear-free ceramic disc valves. The regener-
ation sequence is fixed by the geometry of
the discs and therefore need not be re-en-
tered after a power failure.
5.5.5 Overflow valve
If because of very high drawing of water
(e.g. pressure washer) the pressure loss in
the water softening system is greater than
1.0 bar, then an overflow valve integrated in
the control head opens so that hard water
can bypass the system to limit the pressure
loss. This means that the residual hardness
temporarily increases in the pipe down-
stream of the water softening system.

JUDO QUICKSOFT MEGA 15
Operation
5.6 Filling with salt
The water softening system works automat-
ically. Approximately 180 g of salt is needed
for each regeneration. The regenerating salt
must be replenished at regular intervals.
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.
The stock of salt should not decrease so far
that the liquid level is above the regenerat-
ing salt, as otherwise when replenishing the
salt, it rises excessively.
The regenerating salt is normally replen-
ished in sacks of 25 kg. This salt quantity is
sufficient for at least 120 regenerations.
5.6.1 Message upon low salt level
The salt concentration of the brine reservoir
is automatically regularly checked. If the salt
reservoir is not filled up early enough and
consequently the brine concentration de-
creases too much, a message is output to
the display:
After this message, replenishment with a
quantity of 25 kg of regenerating salt is re-
quired. Then the <OK> key must be briefly
pressed. The warning message is then re-
set.
If the salt is only replenished once the salt
stock is completely used up, the brine level
may temporarily increase. The suction pro-
cess then lasts correspondingly longer.
If there is no longer any regenerating salt
available or if the regenerating salt is not re-
plenished early enough, the water softening
system switches to miser operation.
The remaining salt stock is then primarily
used for disinfection of the ion-exchange
resin and the softening effect is reduced.
In this way, the water softening system re-
mains in a hygienic condition for weeks after
the low regenerating salt state first occurs.
This message can also appear if the
salting process is not performed cor-
rectly during regeneration, e.g. if the
waste water hose is routed at a too-
high level, if the mains water pres-
sure is too low or if the suction hose
connection to the salt/brine tank is
not made correctly.

5.8 Integration of the water
softening system
in building control systems
The water softening system can be integrat-
ed via the potential-free relay into a building
control system (e.g. EIB, LCN or LON).
For example, the potential-free relay is con-
nected to a binary bus coupler. This allows a
fault indication to be forwarded to the build-
ing control system.
5.9 Connectivity module
(accessories)
A retrofittable connectivity module is used to
connect the water softening system via a
LAN connection to the home network and
the Internet.
Using the available iOS/Android app, world-
wide access to comprehensive information,
automated messages and functions of the
water softening system is possible.
Prior to electrical installation, pull the

Warranty and service
8 Warranty and service
To ensure the process operates successfully
for many years after first use, regular inspec-
tion and routine servicing of the system are
essential. Where home automation is con-
cerned, this is governed by DIN EN 806-5.
We recommend that you agree a service
contract.
A service contract is the best way of ensur-
ing correct operation even after the warranty
period has elapsed.
It is desirable that the regular maintenance
work and the supply of consumables, miner-
al solutions, salt or wear parts, etc. is per-
formed by the JUDO factory customer ser-
vice team or by an approved technical
service provider.
8.1 Inspection by the operator
every two months (visual in-
spection)
To retain your legal warranty rights, it is nec-
essary that an inspection be performed at
least every two months.
The operator checks:
– The salt filling level.
– The leak-tightness of the softening sys-
tem (escaping water).
– For damage to the water softener. De-
fective parts must be replaced by cus-
tomer service.
– Messages on the display.
Dependent on the consumed water volume,
the corresponding salt consumption must be
regularly monitored. If necessary, replenish
the regenerating salt (only use quality ac-
cording to DIN EN 973). When replenishing
the salt take appropriate hygiene measures.
Thus, for example, the salt packs should be
cleaned before use so that no impurities can
get into the salt dissolving container. The re-
generating salt must be shaken into the salt
dissolving container directly after undoing
the packaging. In doing so, ensure that the
salt dissolving container is not overfilled and
that after completing the work, it is again
carefully closed and sealed. Do not use par-
tial packs. The salt must only be stored in
clean and dry rooms.
8.2 Six-monthly maintenance
by the operator
In addition to the checks of the 2-month in-
spection, the operator must also check the
following every six months:
– Leak-tightness of the softener to waste
water connection.
No water must flow out of the waste wa-
ter hose (see fig. 8) in the operating po-
sition.
– Salt deposits inside the water trap.
Deposits or incrustations inside the wa-
ter trap must be removed so that the
waste water does not get blocked.
– Soft water hardness.
Checking is performed with a hardness
measuring instrument (in the scope of
supply).
8.3 Annual maintenance
by customer service
Once yearly, a service must be performed
by a licensed technical service provider or
the JUDO factory customer service team.
8.3.1 Message

After an operating period of one year, the
water softening system signals the required
service. The following message is output to

sage is reset by pressing the <OK> key for
