These operating instructions must always
be available at the place of use of the
device.
1.1 Intended use
The device is for the
•Filtration
of drinking water in domestic water piping-
for residential, commercial and industrial
use. It removes coarse and fine-grained
particles from the drinking water, which are
larger or equal to the mesh size of the filter,
in order to prevent
•pipe damage caused by corrosion
•malfunctions of fittings or control and
regulating devices caused by foreign
bodies.
The filter is suitable for use in cold drinking
water up to a maximum water temperature
of 30 °C (86 °F). The water to be filtered
must comply with the European Drinking
Water Directive.
The device can be installed in all commer-
cially available drinking water pipes. Both
installation and use of the device are sub-
ject to the applicable national regulations.
INFO_NO_HEADER
Particles that are smaller than the
mesh size of the filter supplied and
materials causing cloudiness cannot
be filtered out of the water.
1.2 Application limits

CAUTION
An adequately sized waste water
connection (e.g. floor drain) in
compliance with DIN 1986 must be
provided.
In order to ensure safe drink-
ing water hygiene, a free dis-
charge of the waste water acc. to
DIN EN 1717 must be ensured.
Prior to plugging in the device,
ensure that the wastewater con-
nection is functional.
The drain must be large enough so that all
of the waste water can be drained simulta-
neously.
If a waste water connection directly beneath
the filter is not possible, the backwash
water can be drained away via a hose or a
pipe that is connected from the backwash-
ing water valve over a few meters to the
closest waste water connection. The dimen-
sioning of this pipe must correspond to the
backwashing water valve.

3.5 Commissioning
Prior to initial commissioning (or to com-
missioning after maintenance work) fill the
installed device with water and vent:
1. Open the upstream shut-off valve to fill
the device with water. The device is now
under mains pressure.
2. Attention: Immediately plug the power
supply unit in. This automatically carries
out backwashing and the trapped air can
escape. This prevents damage to the
installation due to pressure surges.
After backwashing, the device is vented
and ready for operation.

The device is now ready for oper-
ation.
2 Fault (red warning light)
A fault exists (see chapter 6).
4.2 Cleaning of the sieve insert
(backwashing)
A regular cleaning process is necessary to
remove the residues from the sieve fabric
of the device. This process is called back-
washing.
Suction pipes are provided for backwash-
ing, which rotate around the sieve fabric
of the fine filter. The backwashing valve
opens on the bottom side of the device.
By reversing the water flow from inside to
outside, deposits on the sieve fabric are
carried away and rinsed out with the back-
wash water. The suction pipes also clean
the inside of the transparent filter bowl with
wiper lips during their movement.
The degree of contamination and cleaning
process can be observed from the outside.
INFO_NO_HEADER
The device is backwashed with
filtered water. The filtered water
supply of the domestic installation
remains intact during the backwash-
ing process. No dirty water can reach
the pure water side during the back-
washing.
If the mains voltage fails during the back-
wash process, the backwash is completed
using the built-in batteries. Prior to every
backwashing a battery test is performed.
On a missing, empty or defective battery a
fault indication appears (see chapter 4.4).
A backwashing is no longer possible
4.2.1 Backwashing interval
If cleaning is not performed soon enough,
the result may be damage to the sieve
insert. Large quantities of filtered particles
can deform the sieve fabric and in extreme
case lead to tearing of the sieve fabric.
In addition, larger deposit quantities can
impair the backwashing function mechani-
cally.
According to DIN EN 13443-1 backwashing
the device is required at the latest every six
months.
The manufacturer requires a backwash-
ing:
•at least every 2 months
•if the water pressure drops
•if the filter is visibly dirty
Experience has shown that new installa-
tions in the early stages of installation lead
to increased dirt deposits. In this case, a

7.1 Cleaning
CAUTION
Do not use household cleaning
agents to clean the outside of the
device, but only use clear water to
avoid embrittlement of the plastic.
7.2 Warranty and maintenance
Prerequisite for obtaining the statutory war-
ranty claim is regular backwashing (see
chapter 4.2). The DIN EN 13443-1 pre-
scribes that the backwashing must take
place every six months. JUDO however
recommends to comply with the information
in chapter 4.2.1 Backwashing interval.
To ensure the process operates success-
fully as long as possible, regular inspec-
tion and routine servicing of the device are
essential. Where home automation is con-
cerned, this is governed by DIN EN 806-5.
We recommend the conclusion of a main-
tenance contract, which is the best way
to ensure a good operating function, even
beyond the warranty period. The skilled
tradesmen or the factory customer service
are suitable partners for regular mainte-
nance work and the supply of consumables
and wear materials as well as for possible
repairs.
The maintenance sticker on the device
serves as a reminder of the next mainte-
nance date and should be marked by the
installer after installation.
