2. Intended Use
The installation and operation of the filter is
subject to the following existing national reg-
ulations.
In addition to the operating instructions and
the obliging regulations concerning accident
prevention that exist in the country of opera-
tion and the location of use, the established
technical regulations concerning safe and
professional work, should also be observed.
The water which is to be treated should
fulfil the requirements stipulated by Eu-
ropean drinking water directives!
It is absolutely essential that the manufac-
turer / supplier will be consulted prior to any
operation of the device using water of a dif-
ferent quality, respectively with water that
contains additives.
This filter is designed for use with cold drink-
ing water with a maximum water and envi-
ronmental temperature of 30°C (86°F).
The filter has been developed and manufac-
tured using state of the art technology and
the established safety regulations in Germa-
ny.
The filter may only be operated in accord-
ance with the manufacturer’s specifications.
Any other operation or operation beyond the
specified use, is not in accordance with the
manufacturer’s specifications.
Additional dangers may result in the event of
the device not being operated in accordance
with the manufacturer’s specifications and
non-observance of the danger symbols or
safety instructions. The manufacturer / sup-
plier cannot be made liable for any damages
caused by these additional dangers. The op-
erator is responsible for these risks.
The use of the device in accordance with the
customer’s specifications includes the ob-
servance of the operating instructions.
The manufacturer / supplier should be con-
sulted prior to any operation of the filter oth-
er than in the operational areas stated in

JUDO PROFI-PLUS 7
Intended Use
2.1 Water Pressure
The water pressure should be between 1.5
bar and 10 bar.
The water pressure must not exceed 1.5 bar
as otherwise the backwashing can be im-
paired! If the filter is not backwashed regu-
larly a pressure loss can result and this can
impair the filter function.
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
In the event of water pressure above 10
bar, the pressure reduction valve should be
fitted in front of the Backwash Protective
Filter (see Fig.2). If the operating pressure is
above 10 bar, this may result in defects dur-
ing operation.
2.2 Notes on special dangers
2.2.1 Electrical equipment /
installations
Electrical devices / equipment that are not
splash-water proof and are situated in the di-
rect vicinity of the filter may be damaged by
water leaking from the filter caused as a re-
sult of the device not being operated in ac-
cordance with the manufacturer’s specifica-
tions. In addition this may also result short
circuits if these electrical devices / equip-
ment being connected to the electrical pow-
er supply. In the event of such cases per-
sons are at risk and may sustain electrical
shocks. Therefore any electrical devices /
equipment situated in the direct vicinity
should be splash-water proof, respectively
comply with the statutory requirements for
wet areas (IP44).
Fig. 2: Pressure reducer upstream of the unit
The installation of a pressure re-
duction valve is recommended for
water pressures between 5 bar
and 10 bar.

Product Information
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 dan-
gers 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
filter.
3.2 Test marks
DIN-DVGW mark
The units conform to the technical regula-
tions for drinking water installations in ac-
cordance with DIN 1988. They are tested by
the DVGW (Deutsche Vereinigung des Gas-
und Wasserfaches e.V. technical –scientific
association for the gas and water industries)
in accordance with the requirements of DIN
19632 pressure stage PN 16 for mechanical
filters for use in drinking water and are enti-
tled to bear the DIN-DVGW mark (see fig.
2).
GS sign
In addition the filter has been checked by the
RWTÜV, and has been marked with the GS
sign for certified safety (see Fig. 4).
3.3 Materials used
The materials used are resistant to the phys-
ical, chemical, and corrosive loads to be ex-
pected in the drinking water and fulfil the re-
quirements specified in DIN 19632 (“Me-
chanical filters in drinking water installa-
tions”). All materials are hygienically and
physiologically safe. Plastics (KTW recom-
mendations) and metallic materials fulfil the
requirements of the BgVV (German Federal
Institute for Consumer Health Protection
and Veterinary Medicine).
Particles smaller than the supplied
mesh size and impurities causing
turbidity cannot be filtered out of the
water.

Installation
4. Installation
4.1 General
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
The unit may only be installed by skilled per-
sonnel.
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.
For convenient operation and maintenance
it is absolutely necessary to ensure the giv-
en spacings (see chapter “Discharging the
backwashing water”).
A space of at least 200 mm should be main-
tained above and below the filter. These dis-
tances 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 ac-
cess to the filter!
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
– The ambient temperature must not ex-
ceed 30°C (86°F)! At higher tempera-
tures or direct sun radiation the material
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 giv-
en in the “Installation” chapter is neces-
sary! If the wastewater (backwashing)
cannot be safely and completely dis-
charged, 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 upst-
ream of the water meter!
The shipping carton can be slipped
over the built-in filter to prevent
damage, for instance at construc-
tion sites.

10 JUDO PROFI-PLUS
Installation
4.1.2 Installed position
ATTENTION
(see chapter “Safety information and dan-
gers 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 damage caused by water.
4.1.3 Mounting the built-in rotary
flanges
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.
It is suitable for both horizontal and vertical
pipes.
The built-in rotary flange must be in-
stalled in the direction of flow. This is
marked by a cast in arrow.
(see Fig. 5)
Failure to comply with this means the filter
cannot work.
ATTENTION
(see chapter “Safety information and dan-
gers 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
damage can result, the pipe may burst or the
built-in rotary flange can break. This can re-
sult in major water damage.
In this case, people close to the filter are ex-
posed to a health risk due to the large quan-
tities 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 filter
JPF+¾" - 1¼"
The built-in rotary flange for the filter is sup-
plied with bayonet drill holes. The necessary
seals and screws for this filter have already
been mounted.
Do not unscrew the screws!
– insert the four flange screws in the bayo-
net drill holes on the built-in rotary flange
(see Fig. 5I).
– turn the filter in a clockwise direction as
far as it will go (see Fig. 5II).
– Tighten the four flange screws.
Fig. 5: Built-in rotary flange with Bayonet Fixture
Select the torque (approx. 4 Nm)
so that the gasket closes and the
filter is not damaged or strained.

JUDO PROFI-PLUS 11
Installation
ATTENTION
(see chapter “Safety information and dan-
gers 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 in turn cause water
damage to the house and its installations
(see Fig. 6).
4.2 Discharging the
backwashing water
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
An adequately dimensioned wastewater
connection (e.g. floor drain) to DIN 1986
must be available for the backwashing wa-
ter. If there is no wastewater connection an
appropriately sized bucket can be used.
The dimensioning depends on the local cir-
cumstances (e.g. wastewater pipe gradient,
number of pipe bends, length of the waste-
water pipe, etc.). The dimensioning must at
least allow all the wastewater to be dis-
charged 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 metres 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 en-
sured in accordance with EN 1717.
The following points must be noted if a buck-
et 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 filter is
possible.
– When the bucket is half-filled the back-
washing process must be stopped. Oth-
erwise it is possible for the bucket to
overflow. Therefore the bucket must be
adequately dimensioned and the back-
washing should be carried out quickly.

Always observe the chapter “Intended Use”!
5.1 Commissioning
Before starting up (initial putting into service
or startup after maintenance work), fill the
filter with water and vent!
– To this end, after installation the filter
station is filled with water by opening the
upstream shut-off valve.
– The filter is now at the same pressure as
the water system.
– The enclosed air must then be immedi-
ately removed from the filter station in or-
der to avoid damage to the installation
caused by pressure surges. The filter
station is vented by means of backwash-
ing (see chapter “Discharging the back-
washing water”).
– After backwashing and venting the filter
station is ready for use.
–Note electronics only JPF+¾"–1¼":
A note electronics is accommodated in
the lid of the handwheel. It uses a beep
to remind every two months that the filter
needs to be backwashed.
Activation:
• Lift the lid of the handwheel.
• Insert the two included batteries in the
battery compartment. Use 1.5 V Micro
batteries.
• Replace the handwheel lid.
• You can test the functionality by press-
ing the RESET-key in the lid of the hand-
wheel.
5.2 Funktional description
Water (a) flows through the built-in rotary
flange (10) into the filter.
A coarse filter (9) prevents large dirt parti-
cles from getting into the fine filter (12). The
water flows through the fine filter (12) from
the outside inwards.
The filtered dirt is retained by the fine filter
(12) screen. The adhering dirt is visible
through the transparent filter bell (6). The fil-
tered water (b) then leaves the filter via the
built-in rotary flange (10).

5.3 Backwashing
The filter must be backwashed (=cleaned) at
the specified cycles in order to remove the
filtered dirt from the fine filter screen.
The note electronics is accommodated in
the lid of the handwheel
(2). It uses a beep
to remind every two months that the filter
must be backwashed. Press the RESET-key
(1) (keep pressed for at least 3 seconds) in
the lid of the handwheel
(2) to switch off the
beep and to restart the two-month time inter-
val.
Clean using the
point-rotation method:
Turn the handwheel
(3) counter clockwise to
rotate the suction nozzle in a spiral shaped
movement around the fine filter
(12) siev-
cloth. They progress upwards with each rev-
olution until the entire sieve cloth has been
sucked up one time. That is reached when
the handwheel
(3) has been turned to its lim-
it. At the same time, the flushing valve
(11)
on the bottom of the filter opens and the
backwash water can exit. During this, pure
water flows from the interior to the outside
through the sieve surface in the suction noz-
zle, pulling along the adhering particles.
After reaching the upper limit stop, turn the
handwheel
(3) clockwise to re-close the
flushing valve
(11). The sieve cloth in the
fine filter
(12) is then sucked through the
suction nozzle a second time. Repeat this
procedure until reaching the lower limit stop.
During this step, the suction nozzle does not
only clean the sieve cloth in the fine filter
(12) but also the transparent filter bell
(6) us-
ing a rubber lip on its exterior side (see
Fig.8).

All sizes of filter are backwashed
with treated water. The supply of
treated water to the filter station is
maintained throughout the back-
washing process. Dirty water can-
not get into the clean water side
during backwashing.

JUDO PROFI-PLUS 15
Operation
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Repeat this procedure until reaching the
lower limit stop!
If the closing operation is interrupted before
reaching the lower limit stop, the closing
valve is not completely closed. The result is
that water permanently leaks. Along with
high water consumption, this can lead to wa-
ter damage, especially if the backwash wa-
ter is not drained off as described in the
chapter “Discharging the backwashing wa-
ter”.
5.3.1 Backwashing interval
The filter must be backwashed:
– Every two months at the latest.
– If the water pressure falls.
– If the filter is visibly dirty.
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
An interval greater than two months until the
next backwashing can lead to a contamina-
tion of the filter. That can result in a signifi-
cant reduction in the water quality
.
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 in-
sert the more frequently backwashing is re-
quired!
From experience, increased dirt is deposit-
ed 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 dam-
age to the screen. Large quantities of filtered
particles can deform the screen. As a result,
proper function of the filter is no longer en-
sured. In addition, large quantities of dirt can
cause mechanical damage to the back-
washing function.
5.3.2 Note electronics
only for JPF+¾" – 1¼"
The note electronics in the handwheel re-
minds to backwash every 2 months. You
can also mark the next backwash date using
the adjusting ring under the handwheel.
– Push the RESET-key to stop the beeping.
This also restarts the 2-month time inter-
val. Be sure to replace exhausted batter-
ies in time. The beep is only considered
an additional reminder for backwashing.
Independent of that, the backwashing
needs to be carried out every two
months.
Both the degree of soiling and the
cleaning process can be observed
from the outside.

Operation
5.4 Modifications / changes /
spare parts
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Only original spare parts are to be used!
Independent modifications and changes are
prohibited for safety reasons! These can im-
pair 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.
5.4.1 Servicing / Repair
Before carrying out any work on the filter,
which extends beyond pure operational con-
trol, the filter must be depressurised! Failure
to observe this can lead to an uncontrolled
escape of water and therefore lead to water
damage in the building. Strictly comply with
the instructions given in the “Installation”
and “Maintenance” chapters.

JUDO PROFI-PLUS 17
Faults
5.5 Stoppages
ATTENTION
(see chapter “Safety information and dan-
gers 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 dam-
age! Damaged flanged surfaces cannot
close tight. As a result, escaping water
can damage the building and installa-
tions.
– 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 fil-
ter parts.
– When restarting the filter, follow the in-
structions for a new filter.

gers 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 substances can chemically attack the
plastic parts, which can lead to brittleness or
even fractures.
Such cleaners must therefore not be
used.
7.2 Checking the note electronics
only JPF+¾" – 1¼"
Check the note electronics as follows:
– Press the RESET-key for at least 3 sec-
onds.
If a beep sounds, the note electronics are
functioning and the batteries still have suffi-
cient capacity. This battery test does not
have any influence on the two-month inter-
val.
If no beep sounds, the batteries have to be
replaced with fresh batteries.
Replacing the batteries:
– Lift the lid of the handwheel.
– Replace the batteries located in the bat-
tery compartment with new, identical
batteries (size AAA).
– Replace the handwheel lid.
– Press the RESET-key in the lid of the
handwheel for at least 3 seconds. The
two-month time interval is restarted.
– Used batteries are to be returned to a dis-
tributor or to one of the returning facilities
established to this purpose by the public
recycling entities.
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
To make sure the total interval of two-
months is not exceeded, backwash the filter
after replacing the batteries.

7.3 Silver sieve
The sieve insert:
The filter contains a sieve insert with a sil-
ver plated stainless-steel sieve cloth. This
silver coating ensures optimal germ-protec-
tion prophylaxis in the filter. The germ pro-
tection in such a sieve insert is used up af-
ter ca. 2 years operation, but maintains its
function as a protective filter.
If you want to maintain the germ-protection
prophylaxis, you need to have the sieve in-
sert replaced by authorised personnel every
2 years.
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 at least every 2 months, after operat-
ing conditions exist … ".
Regular servicing is indispensable in order
to continue to achieve a successful process
for many years after the unit is put into serv-
ice. In the building services sector this is
covered by DIN 1988, Part 8.
A servicing agreement is the best way to en-
sure a good operating function beyond the
warranty period.
Wherever possible, the regular servicing
work and supply with consumables and
wearing materials, etc. should be carried out
by the specialist trade or the factory’s cus-
tomer service department.

– Non-silver coated special mesh sizes
The filters come factory equipped with a sil-
ver-plated stainless-steel sieve with a mesh
size of 0.1 mm.
If desired, non-silver coated mesh sizes of
0.03 mm, 0.32 mm and 0.5 mm are available
for technical and industrial use.
Filters with special mesh sizes are not in-
cluded in the inspection according to DIN
19632 and for this reason are not allowed to
bear the DVGW mark.
ATTENTION
(see chapter “Safety information and dan-
gers due to non-compliance”)
Filters with mesh sizes larger than 0.1 mm
only filter correspondingly large particles
from the water. But backwashing must also
be carried out here latest after two months to
prevent germ formation.
A mesh size smaller than 0.1 mm causes
smaller particles to also be filtered out of the
water. That means that the filter can become
contaminated faster. The backwash inter-
vals should be shortened in such cases.
Carry out backwashing latest when the filter
is visibly soiled or the water pressure drops.
