The water to be filtered must possess
quality of drinking water!
It is absolutely essential that the manufac-
turer / supplier will be consulted prior to any
operation of the device using water of a
different quality, respectively with water that
contains additives.
This filter is suitable for use in cold drinking
water up to a maximum ambient tempera-
ture of 86 °F (30 °C).
The filter has been developed and manufac-
tured using state of the art technology and
the safety regulations generally accepted in
Germany.
The filter may only be operated in accor-
dance with the manufacturer’s specifica-
tions. Any other operation or operation
beyond the specified use, is not in accor-
dance with the manufacturer’s specifica-
tions.
Additional dangers exist in case of non-
intended use and where the danger symbols
and safety information are not observed.
The manufacturer/supplier are not liable for
any losses or damage resulting from such
use. The risk is borne solely by the user.

Intended use
2.1 Water pressure
The water pressure should be between
22 psi (150 kPa) and 145 psi (1000 kPa).
The water pressure must not fall below
22 psi (150 kPa) as otherwise the back-
washing can be impaired! If the filter is not
backwashed regularly a pressure loss can
result and this can impair the filter function.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
In the event of water pressure above
145 psi (1000 kPa), the pressure reduction
valve should be fitted in front of the back-
wash protective filter (see fig. 2). If the
operating pressure is above 145 psi (1000
kPa),
this may result in defects during
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
direct vicinity of the backwash protective
filter may be damaged by water leaking from
the backwash protective filter caused as a
result of the device not being operated in
accordance with the manufacturer’s specifi-
cations. In addition this may also result short
circuits if these electrical devices / equip-
ment being connected to the electrical
power supply. In the event of such cases
persons are at risk and may sustain elec-
trical 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).

Product information
3. Product information
3.1 Intended purpose
This filter is suitable for use in cold drinking
water up to a maximum ambient tempera-
ture of 86 °F (30 °C).
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
filter.
3.2 Materials used
The materials used are resistant to the
physical, chemical, and corrosive loads to
be expected in the drinking water and fulfill
the requirements specified in the DIN EN
13443-1 and DIN 19628 standards
(“Mechanical filters in drinking water instal-
lations”) in Germany. All materials are
hygienically and physiologically safe. Plastics
fulfill the official guidelines of the German
federal environmental agency and the
DVGW work sheet W270. Metallic materials
fulfill the requirements of the German stan-
dard DIN 50930-6 (Impact on the drinking
water quality).
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 support the filter
safely.
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 (8 inch) should
be maintained above and below the filter.
These distances are necessary to be able to
properly carry out the backwashing (see
chapter “Backwashing”).
Particles smaller than the supplied
mesh size and impurities causing
turbidity cannot be filtered out of the
water.

8 JUDO SPEEDY-LongLife
Installation
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 86 °F (30 °C)! 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
given in the “Installation” chapter is
necessary! If the wastewater (back-
washing) cannot be safely and
completely discharged, then this may
result in water damage to the house and
installations therein.
– 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/main-
tenance, 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 backwash
protective filter upstream of the water
meter!
4.1.2 Installed 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 an arrow on the flange.
Failure to comply with this means that back-
washing is impossible. By and by this leads
to an increasing pressure loss.
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
damage can 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.

JUDO SPEEDY-LongLife 9
Installation
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 a profiled flange seal.
Undo the union nuts of the built-in rotary
flange and fit to the pipe with the sleeve.
Note the installed dimensions!
Position the filter with pre-fitted built-in rotary
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 of flow 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
(see fig. 4). Failure to observe this can lead
to leaks and water escaping. This can in turn
cause water damage to the house and its
installations.
Select the torque (approx. 4 Nm) so
that the gasket closes and the filter
is not damaged or strained!

10 JUDO SPEEDY-LongLife
Installation
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) in
accordance with DIN 1986, or local equiva-
lent, must be in place. If there is no waste-
water connection an appropriately sized
bucket can be used.
The dimensioning depends on conditions on
site (e.g. wastewater pipe gradient, number
of pipe bends, length of the wastewater
pipe, etc.). 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 DIN EN 1717,
or local equivalent.
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
Before starting up (initial putting into service
or startup after maintenance work), fill the
backwash protective filter with water and
vent!
– To this end, after installation the filter 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 imme-
diately removed from the filter in order to
avoid damage to the installation caused
by pressure surges. The filter is vented
by means of backwashing (see chapter
“Discharging the backwashing water”).
– After backwashing and venting the filter
is ready for use.
5.2 Functional description
Water flows through the built-in rotary flange
(1) into the backwash protective filter. A
coarse filter (JSY-LF 1½" – 2") prevents
large dirt particles from getting into the fine
backwash protective filter. These large dirt
particles cannot be removed by the back-
washing equipment. The water flows
through the fine filter from the outside
inwards. The filtered dirt is retained by the
fine filter screen. The adhering dirt is visible
through the transparent filter cover (3). The
filtered water then leaves the backwash
protective filter via the built-in rotary flange
(1).

14 JUDO SPEEDY-LongLife
Operation
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.
A complete backwashing process is carried
out by turning the handwheel through a full
turn. At the same time the handwheel
ensures free discharge.
When the handwheel is rotated in any direc-
tion three suction pipes rotate around the
fine filter screen.
At the same time a patented ceramic
flushing valve on the underside of the back-
wash protective filter opens so that the back-
washing water can flow out. The treated
water flows from the inside outwards
through the screen into the suction pipe,
taking the adhering particles with it. During
this time treated water flows out. The fine
filter screen is cleaned. At the same time the
inside of the transparent filter cover is
cleaned together with the wiper lips of the
suction pipe.
Immediately continue turning the handwheel
until it audibly locks into place.
The ceramic flushing valve thus closes
again and the backwashing process is
completed.
This backwashing process can be repeated
if necessary.
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
This backwashing process must be carried
out until the audible locking into place of the
handwheel. If the locking process is discon-
tinued before the audible locking into place
the ceramic flushing valve is not fully 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”.
5.3.1 Backwashing interval
The filter must be backwashed:
– every two months at the latest
– if the water pressure falls.
– if the backwash protective filter is visibly
dirty
All filter sizes are backwashed with
treated water. The treated water
supply within the domestic installa-
tion is maintained throughout the
backwashing performance. During
the backwashing any wastewater
can't get into the pure water side.
The degree of pollution as well as
the cleaning off operation can be
watched from outside.
There is a display button on the built-in
rotary flange (JSY-LF ¾" – 1¼"), respec-
tively on the filter bell (JSY-LF 1½" – 2")
attached to the filter. It can be slid along
the months scale. This enables the back-
washing interval to be monitored.

JUDO SPEEDY-LongLife 15
Operation
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.
Unauthorized 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 has
to be carried out!
Experience shows that increased dirt is
deposited during the initial running period. If
so, the unit has to be flushed more often
than usual.
Failure to flush in good time can cause
damage to the screen. Larger quantities of
filtered particles can deform the screen and
as an extreme incident cause the tearing of
the sieve. As a result a filter function is not
any longer ensured. In addition, larger quan-
tities of dirt can cause mechanical impair-
ment concerning the backwashing function.
5.4 Modifications / changes /
spare parts
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Only original spare parts are to be used!
Arbitrary modifications and changes are
prohibited for safety reasons! They can
impair the function of the filter, lead to leaks
and as an extreme incident they can lead to
the bursting of the filter.
The imprinted test marks are only valid if
original spare parts are used.
5.4.1 Servicing / repair
Before carrying out any work on the filter,
that is beyond pure operation induced
control, the filter has to be depressurized!
Failure to observe this can lead to an uncon-
trolled escape of water and therefore lead to
water damages in the building. Strictly
comply with the instructions given in the
“Installation” and “Maintenance” chapters.

16 JUDO SPEEDY-LongLife
Faults
5.5 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”
has imperatively to be observed!
– Protect the flange surfaces from
damage! Damaged flange surfaces
cannot close tight any longer. As a
result, escaping water can damage the
building and installations.
– Ensure that no dirt can get into the filter!
Upon re-commissioning this dirt can get
into contact with the drinking water and
be discharged into the drinking water.
The health of people consuming polluted
water is at risk.
– Store the filter in frost-free conditions!
The water contained in the hollows of the
filter can freeze due to frost and thus the
filter can be mechanically damaged to a
degree that it will become loose at
operating pressure or that it can burst.
Leaking water can cause major material
damages to the building. In addition,
people near the filter can be injured by
blistering filter parts.
– When re-commissioning the filter, same
course of action as applied to the new
filter.
6. Faults

Always observe the chapter “Intended use”!
7.1 Cleaning
ATTENTION
(see chapter “Safety information and
dangers due to non-compliance”)
Use only clear, drinking water concer-
ning the cleaning of the housing and the
transparent filter hood.
Domestic all-purpose cleaners and glass
cleaners can contain up to 25 % solvents or
alcohol (spirits) and may not be used.
These substances can chemically attack the
plastic parts, which can lead to brittleness
right up to [brittle] fractures.
These kinds of cleaners must therefore
not be used.
