3. Product Information
3.1 Intended purpose
This filter is suitable for use in cold drinking
water up to a water temperature of maxi mum
30 °C (86 °F).
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Please refer to the chapter on “Intended
Use” for use restrictions.
This filter removes coarse and fine-grained
particles from the water which are larger
than or equal in size to the mesh size of the

the water.

JUDO EASY FILT DOS 7
Installation
4. Installation
4.1 General
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
The unit may only be installed by skilled
personnel.
The chapter “Intended Use” must always be
observed!
The pipes must be able to safely support the
filter.
Otherwise mechanical damage or fractures/
bursts can occur in the pipes. This can result
in major water damage. People close to the
filter are exposed to a health risk due to the
large quantities of water released. There-
fore, if necessary, the pipes must be addi-
tionally fixed or supported.
A space of at least 200 mm should be main-
tained above and below the filter. These
distances are necessary to be able to
properly carry out the backwashing (see
chapter “Backwashing”).
4.1.1 Requirements for the place of
installation
The room where the unit is installed must
be dry and frost free!
Unauthorised persons must not have
access to the filter!
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
– The ambient temperature must not
exceed 30 °C (86 °F)! At higher tempe-
ratures or direct sun radiation the mate-
rial can be damaged and the filter hood
can even break.
– In order to be able to safely discharge
the wastewater in operation and in case
of any defects that occur in the system,
precise compliance with the details
given in the “Installation” chapter is
necessary! If the wastewater (back-
washing) cannot be safely and
completely discharged, the house and
installations can be damaged by water.
– A shut-off valve must be installed
upstream of the filter! This enables the
water supply to the filter to be interrupted
during installation, servicing/mainte-
nance, repairs and in case of malfunc-
tions. Floods and serious water damage
to house installations can therefore be
avoided.
– The unit can be installed in all standard
drinking water pipes.
– It is not permitted to install the filter
upstream of the water meter!
4.1.2 Installing position
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Always install the filter in a vertical position
(± 5°)!
Failure to observe this can cause uncon-
trolled backwashing water to escape and
can result in water damage.

4.1.3 Mounting the built-in rotary
flange
Install using the supplied built-in rotary
flange. The built-in rotary flange is used as a
connecting element between the pipe and
the filter.
The built-in rotary flange must be
installed in the direction of flow. This is
marked by a cast in arrow.
Failure to comply with this means the filter
cannot work.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
The flange surface of the built-in rotary
flange must be in a horizontal position! The
built-in rotary flange must be fitted so that
mechanical stresses cannot occur! Other-
wise mechanical damage can result in the
built-in rotary flange. Otherwise mechanical
damagecan result, the pipe may burst or the
built-in rotary flange can break. This can
result in major water damage.
In this case, people close to the filter are
exposed to a health risk due to the large
quantities of water.
Therefore, during installation, ensure that no
large forces act on the pipe, built-in rotary
flange and filter.
4.1.4 Installing the backwash
protective filter
The filter is connected using the supplied
built-in rotary flange. It consists of the built-
in rotary flange and profiled flange seal.
Undo the built-in rotary flange union nuts
and fit to the pipe with the sleeve.
Note the installed dimensions!
Positionthefilterwithpre-fittedbuilt-inrotary
flange between the sleeves, insert the flat
seals and screw using the union nut.
The cast in arrow of the built-in rotary flange
must match the direction offlow of the water.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
The section of the profiled flange gasket
must point towards the built-in rotary flange.
Failure to observe this can lead to leaks and
water escaping.This can inturn cause water
damage to the house and its installations.

4.2 Discharging the
backwashing water
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
For the backwashing water a wastewater
connection (for example a floor drainage)
must be in place.
The dimensioning depends on conditions on
site (e.g. wastewater pipe gradient, number
of pipe bends, length of the wastewater
pipe, etc.). The dimensioning must at least
allow all the wastewater to be discharged at
the same time. If it is not possible to provide
a wastewater connection directly beneath
the filter, the flushing water can be fed
several meters to the next wastewater
connection, either through a hose or a pipe
to be fitted to the flushing water valve. This
pipe must have the same dimension as the
flushing water valve.
In all options, a free discharge must be
ensured in accordance with the EN 1717
standard.
The following points must be noted if a
bucket is used for backwashing:
– If the mains pressure is high, water can
splash out of the bucket. In this case,
damage to property close to the back-
wash protective filter is possible.
– When the bucket is half-filled, the back-
washing process must be stopped.
Otherwise it is possible for the bucket to
overflow. Therefore the bucket must be
adequately dimensioned and the back-
washing should be carried out quickly.

Operation
5. Operation
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Always observe the chapter “Intended Use”!
5.1 Commissioning
Prior to the start-up (Initial start-up or start-
up effected upon maintenance works) do fill
the filter with water and ventilate the filter.
– In order to do so the filter, when having
been installed, is filled with water
through the opening of the upstream
positionned shut-off valve.
– The filter has now become system-
pressurized.
– The enclosed air has then immediately
to be let out of the filter to avoid device
damage through water hammers. The
ventilation of the filter is effected via a
backwash performance (see chapter:
“Discharge of the backwash water“)
upon the backwashing and ventilation
having been effected, the filter is ready-
to-operate.
5.2 Functional description
Unfiltered water runs through the built-in
rotary flange (3) into the backwash protec-
tive filter. The water flows through the fine
filter outside-inside, dirt particles getting
stuck on the filter cloth of the fine filter. The
adherent contamination is externally visible
through a transparent filter hood (5). After
having passed through the backwash
protective filter, the water to be treated is
redirected upwards and flows through a
phosphate metering device (1). In the
process the drinking water is added small
amounts of solved food-grade polyphos-
phate (2). Thus the natural amount of
calcium and magnesium contained in
drinking water is stabilized. From this point
on no harmful lime deposits (e. g. found in
pipings or at heater rods) can develop in the
installation. Phosphate is a mineral that is
also added to various foods.
When stabilizing the water hardness with
polyphosphates the consumption of deter-
gents is substantially lower. Due to lower
water hardness a washing machine e. g.
needs respectively less detergent.

5.3 Exchanging the phosphate
cartridge
The phosphate cartridge must be
exchanged after 12 months at the latest!
The phosphate cartridge is exchanged
as follows:
1. Close the shut-off valves (1) upstream
and downstream of the device (see Fig. 7).
2. Turn the handwheel for backwashing (2)
contraclockwisely so that the pressure remai-
ning in the device can escape (see Fig. 8).
3. Unscrew the union nut (3) at the phos-
phate cartridge contraclockwisely.
4. Lift the empty phosphate cartridge (4) out
of the device (see Fig. 9).
5. Insert the new phosphate cartridge (5)
into the device.
6. Screwin the union nut (3) clockwisely and
tighten ithand-tight (approx. 1 Nm) (see Fig.
10).
7.
Turn the handwheel for backwashing (2)
clockwisely all the way to the stop .
8. Open the shut-off valves (1) again.
9. De-aerate the device. At an extraction
point let out water for about 1 minute with a
flow rate of approx. 1000 - 2000 l/h (resp.
4,4 - 8,8 gal/min).

Operation
5.4 Backwashing
The filter must be backwashed (=cleaned) at
the specified cycles in order to remove the
filtered dirt from the fine filter screen.
The backwashing takes place at full tap
(water system) pressure.
To clean the backwash protective filter, the
handwheel must be turned to the left up to
the limit stop, thereby opening the flushing
valve. While the handwheel is being turned
the flushing water escapes. The flushing
valve must then be closed again by turning
the handwheel to the right.
The ceramic flushing valve thus closes
again and the backwashing process is
completed.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If the locking procedure is interrupted the
flushing valve is not completely closed.
Water permanently escapes as a result.
Apart from high water consumption, this can
also cause water damage, especially if the
backwashing water is not discharged as
described in the chapter “Discharging the
backwashing water”.
5.4.1 Backwashing interval
The backwash protective filter must be
backwashed:
– Every two months at the latest.
– If the water pressure falls.
– If the backwash protective filter is visibly
dirty.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If the interval until the next backwashing is
longer than two months, the particles on the
filter screen can stick or a large filter pres-
sure resistance can result.
Unauthorised persons must not operate the
filter! Persons who operate the filter must
observe the operating instructions. Failure
to observe these instructions can result in
damage to property and personal injuries.
The smaller the mesh size of the screen
insert the more frequently backwashing is
required!
From experience, increased dirt is depos-
ited during the initial running period. In this
case the unit will have to be flushed more
frequently than normal.
Failure to flush in good time can cause
damage to the screen. Large quantities of
filtered particles can deform the screen. As
a result, proper function of the filter is no
longer ensured. In addition, large quantities
of dirt can cause mechanical damage to the
backwashing function.
All sizes of filter are backwashed
with treated water. The supply of
treated water to the filter station is
maintained throughout the back-
washingprocess. Dirty water cannot
get into the clean water side during
backwashing.
Both the degree of soiling and the
cleaning process can be observed
from the outside.
There is a display button on the built-
in rotary flange attached to the back-
wash protective filter. It can be slid
along the months scale. This enables
the backwashing interval to be moni-
tored.

Operation
5.5 Modifications / changes /
spare parts
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Only original spare parts are to be used!
Independent modifications and changes are
prohibited for safety reasons! These can
impair the function of the filter, lead to lead
and in extreme cases can cause the filter to
burst.
The test marks imprinted on the unit are only
valid if original spare parts are used.
5.5.1 Servicing / Repair
Before carrying out any work on the filter,
which extends beyond pure operational
control, the filter must be depressurised!
Failure toobserve thiscan lead to an uncon-
trolled escape of water and therefore lead to
water damage in the building. Strictly
comply with the instructions given in the
“Installation” and “Maintenance” chapters.
5.6 Stoppages
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
If a filter has to be removed from the flange
or unscrewed, the chapter „Intended use“
must always be observed!
– Protect the flange surfaces from
damage! Damaged flange surfaces
cannot close tight. As a result, escaping
water can damage the building and
installations.
– Ensure that no dirt can get into the filter!
This dirt can get into contact with and be
discharged into the drinking water when
the filter is switched back on. The health
of people who drink dirty water is at risk.
– Store the filter in frost-free conditions!
Frost can cause any water contained in
the filter voids to freeze and thus cause
mechanical damage to the filter so that it
leaks at operating pressure or can burst.
Leaking water can cause major damage
to the building. In addition, people near
the filter can be injured by breaking off
filter parts.
– When restarting the filter, follow the
instructions for a new filter.

Always observe the chapter “Intended Use”!
7.1 Cleaning
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Only use clear, clean drinking water to
clean the housing and transparent filter
cover.
Domestic all-purpose cleaners and glass
cleaners can contain up to 25% solvents or
alcohol (spirits).
These substancescan chemically attack the
plastic parts, which can lead to brittleness or
even fractures.
Such cleaners must therefore not be
used.
8. Warranty and Services
In order to comply with the legal warranty
claim, according to DIN 1988, Part 8, it is
necessary that the "… backwashing takes
place according to the existing operating
conditions, at the latest, however, every two
months … ".
Further, an annual "… check of the set
discharge pressure at the pressure gauge
(visual check) when no water is flowing and
at the peak flow (large amount drawn off) …"
is necessary.
Regular servicing is indispensable in order
to continue to achieve a successful process
for many years after the unit is put into
service. In the building services sector this is
covered by DIN 1988, Part 8.
A servicing agreement is the best way to
ensure a good operating function beyond
the warranty period.
Wherever possible, the regular servicing
work and supply with consumables and
wearingmaterials, etc. shouldbe carried out
by the specialist trade or the factory’s
customer service department.

Chère cliente, cher client,
nous vous remercions pour la confiance
que vous nous avez témoignée en ache-
tant cet appareil. Ce filtre est un appareil
réalisé selon les toutes dernières
connaissances techniques.
Ce filtre de protection à rétrolavage est
destiné à une eau (de ville, pluie, puit) et
à un emplacement (cave, garage,…) ne
pouvant dépasser une température de
30 °C (86 °F) au maximum. Il extrait de
l'eau, par une filtration via tamis, les
particules grossières et fines dont la
taille est plus grande ou égale aux ouver-
tures du tamis de filtrage.
Au moyen d’une unité spéciale de traite-
ment de l’eau la tendance de l’eau
potable à former des dépôts calcaires est
réduite.
Les particules qui sont plus petites que
les ouvertures du filtre utilisé ainsi que
les turbidités et les substances
dissoutes dans l'eau ne peuvent pas être
extraites par ce type de filtrage.
Chaque filtre a été consciencieusement
contrôlé avant sa livraison. Toutefois, en
cas d'apparition de difficultés, veuillez
vous adresser au service clientèle
compétent (cf. au verso).
