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

2.1 Scope of supply
•Dosing pump with water meter
•Rotary flange fitting with bayonet con-
nection and threaded fitting
•Wall mounting (only JJD 4)
•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
