of the device. In this case, the fol-
lowing must be observed:
•Electronic parts may become hot
during operation. Risk of burns!
Do not touch parts!
•Parts of the device may move.
Risk of injuries! Proceed with
extreme care and caution!
1.3.1 Electrical danger
ELECTRO_NO_HEADER
Risk of electric shock
No electrical wiring or equipment that is
not splash-proof may run or be stored
below the device. Electrical devices/
equipment located in the vicinity of the
4 JUDO JULDOS 1703383 • 2022/10
Safety
device must be splash-proof or comply
with the legal regulations for wet rooms.
Only the supplied power supply unit may
be used to connect the unit to the power
supply. This reduces the mains voltage
for operating the electronics to a harm-
less low voltage of 24 V.
A splash-proof socket is required for
connection to the electrical grid, in
accordance with the legal regulations for
wet rooms.
Only low voltages can be used for the
remote transmission of the status or
fault indication via the floating output.
Switching voltage: maximum 24 V
Amperage: maximum 1 A
The power supply unit must be discon-
nected for performance of the electrical
installation.
1.3.2 Warning of property damage
WARNING
Risk of water damage or damage
to property
The device may only be installed by
technical service providers.
Installation of the device upstream of the
water meter is forbidden.
The installation room must be dry and
free from frost.
The ambient temperature must not
exceed 30 °C. In higher temperatures or
direct sunlight, material damage may
occur up to and including breakage of
device parts.
If no bypass valve (JQX; see chapter
9.4) is installed, shut-off valves must
be installed to interrupt the water sup-
ply and prevent the water from flowing
back to the unit during installation, main-
tenance, repair or malfunctions of the
device.
For JJD 4: The pipe must be able to
safely support the device (weight: see
chapter 9). If necessary, the pipes must
be provided with additional fastenings or
support.
For JJD 4: Always install the device in
an upright position (± 5°). Otherwise, cor-
rect function of the device is not guaran-
teed.
For JJD 10 - 25: Position the device ver-
tically on solid, stable and load-bearing
ground, to ensure it is securely located.
For the installation of the device in
domestic water piping systems, only use
the supplied built-in rotary flange (see
chapter 3.4).
The flange surface of the rotary flange
fitting must be vertical (i.e. point for-
wards).
The rotary flange fitting must be fitted so
that it is free from mechanical stress or
strain. Otherwise mechanical damage to
the pipe or the rotary flange fitting up to
and including breaks can result.
For proper sealing the profiled side
of the profile flange seal must point
towards the rotary flange fitting (see
chapter 3.4). If this is not observed, the
sealing may not be perfect resulting in
water escaping.
Only operate the device in a technically
faultless condition:
•Check for damage prior to installa-
tion.
•Immediately have any malfunctions
in operation rectified by qualified
technical personnel.
Persons who, due to their physical, sen-
sory or mental abilities or their inexperi-
ence or lack of knowledge, are unable to
operate the device safely may not oper-
ate it without supervision or instruction
from a responsible person.
1703383 • 2022/10 JUDO JULDOS 5
Safety
The mains voltage must not be inter-
rupted (e.g. via a light switch). If the
device is not permanently supplied with
power, dosing of mineral solution or pro-
vision of a warning in case of faults will
not be possible.
For reasons of hygiene, JUL mineral
solutions may only be transported and
stored in sealed mineral solution con-
tainers.
The storage temperature of JUL mineral
solution must be greater than 5 °C and
less than 25 °C.
Do not use household cleaning agents
to clean the outside of the device, rather
only use a damp cloth to avoid embrittle-
ment of the plastic.
Never use a spray cleaner or scouring
cleaning agent. Ensure no moisture can
get into device openings when cleaning.
The device may only be repaired by tech-
nical service providers or JUDO cus-
tomer service.
Only use original spare parts for repairs.
Before performing work on the device
that goes beyond pure operational use,
the device must be depressurised. If
this is ignored, the result may be uncon-
trolled egress of water resulting in water
damage.
In the event of temporary removal of the
device
•protect the flange surfaces against
damage to ensure proper sealing.
•protect the device from dirt so as not
to impair drinking water hygiene.
•store the device in a frost-free place
to prevent damage caused by freez-
ing water and possible resultant loss
of leak-tightness.
Unauthorised conversions and changes
are forbidden for safety reasons. These
can impair the functioning of the device,
leading to leaks and, in the worse case
scenario, to bursting of the device.

•Installation and operating instructions
2.2 Function description
Dosing pump
During drawing of water, water of the drink-
ing water system flows through the water
meter. The output signal of the incorporated
flow sensor controls the pump drive speed.
The precisely operating plunger pump trans-
ports the dissolved minerals out of the min-
eral solution container via a dosing hose to
the injection point in the water meter. Here
the dosing solution is injected against the
water pressure into the water pipe so that
the minerals mix thoroughly with the water
flowing through.
The dosing quantity of the mineral solution
can be regulated via the control to three
different levels: minimum, normal or maxi-
mum.
The pump head via which the mineral solu-
tion is raised, is located at the bottom end
of the pump console, just above the bottom
of the mineral solution container. It does not
require bleeding.
After an empty message, the dosing pump
switches off automatically to prevent dry-
running. It can only restart its operation,
once a filled mineral solution container is
attached (see chapter 5.3).

Product information
2.2.1 JUL mineral solution
The following JUL mineral solutions are
available:
•JUL-W (Tabs; not for Switzerland)
•JUL-H (Tabs)
JUL-W
Application:
Galvanized pipes
Method of operation:
Orthophosphates and silicates react with
the metal of the piping to form a difficult-to-
dissolve compound, so that the pipe mater-
ial is shielded against the corrosive effects
of the water.
JUL-H
Application:
Mixed-metal installations
Method of operation:
The polyphosphates surround the calcium
and magnesium ions responsible for the
hardness, preventing them from forming
any more calcium/magnesium carbonate
(limescale) crystals.
Notes:
•The hardness stabilisation process was
checked according to the DVGW (Ger-
man Technical and Scientific Associ-
ation for Gas and Water) worksheet
W 512 at 80 °C; the result was a certi-
fied reduction of limescale formation of
more than 99 %.
•The hardness stabilisation occurs even
when only small phosphate quantities
are used, so that when using JUL-H,
the specified strict limit values for phos-
phates in drinking water are adhered to.
2.3 Remote monitoring
The device can be integrated in building
control systems (see chapter 6).
2.4 Materials used
The materials used are resistant to the
physical, chemical and corrosive loads
expected to be encountered in drinking
water. They fulfil the specifications required
by DIN EN 19635 (“Dosing apparatus for
drinking water treatment”).
All materials are hygienically and phys-
iologically harmless. Plastics fulfil the
KTW Guideline (Guideline for the Hygienic
Assessment of Organic Materials in Contact
with Drinking water) of the DVGW Work-
sheet W 270. Metallic materials fulfil the
requirements of DIN 50930-6 (Effect of
metallic materials on the quality of drinking
water).
2.5 Approval marks
