Safety
1 Safety
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
•Pressure reduction
•Backflow prevention
(only JUKOMAT-LF-AT 1½" - 2")
of drinking water in domestic water piping
and for residential, commercial and indus-
trial 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 built-in pressure reducer allows the
water pressure to be regulated to a lower
value, which protects the downstream
installations and contributes to lower water
consumption.
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
1.2.1 Water quality
The water to be filtered must comply with
the European Drinking Water Directive
(98/83/EC). Before using the device with
water that does not comply with this Direc-
tive, it is essential to consult the manufac-
turer.
1.2.2 Water pressure
CAUTION
The water pressure must not exceed
16 bar input pressure. The device
must not be installed if the water
pressure is above 16 bar (even for a
short time)!
Nominal pres-
sure
PN 16
Operating pres-
sure
1.5 bar - 16 bar
Downstream
pressure
1.5 bar - 6 bar

Safety
1.3 Safety instructions
1.3.1 Electrical danger
ELECTRO_NO_HEADER
Risk of electric shock
No electrical wiring or equipment that is
not splash-proof may run or be stored
below the device. Electrical devices/
equipment located in the vicinity of the
device must be splash-proof or comply
with the legal regulations for wet rooms.
Only the supplied power supply unit may
be used to connect the unit to the power
supply. This reduces the mains voltage
for operating the electronics to a harm-
less low voltage of 9 V.
A splash-proof socket is required for
connection to the electrical grid, in
accordance with the legal regulations for
wet rooms.
Only low voltages can be used for the
remote transmission of the fault indica-
tion via the potential-free output!
Switching voltage: maximum 24 V
Amperage: maximum 1 A
1.3.2 Warning of property damage
WARNING
Risk of water damage or damage
to property
The device may only be installed by
qualified technical personnel.
The installation room must be dry and
free from frost.
The ambient temperature must not
exceed 30 °C! In higher temperatures
or direct sunlight, material damage may
occur up to and including breakage of
device parts.
An adequately sized wastewater connec-
tion (e.g. floor drain) in compliance with
DIN 1986 must be provided.
In order to ensure safe drinking water
hygiene, a free discharge of the waste-
water acc. to DIN EN 1717 must be
ensured.
The pipe must be able to safely support
the device (weight: see chapter 8). If nec-
essary, the pipes must be provided with
additional fastenings or support.
If no bypass valve is installed, a shut-
off valve must be installed upstream and
downstream of the unit in order to inter-
rupt the water supply during installation,
maintenance, repair or malfunction of
the device.
Install the device in a vertical position
(± 5°); the connection for waste water
from backwashing must be directed
downwards. Otherwise, water may
escape and cause water damage.
For the installation of the device in
domestic water piping, only use the sup-
plied built-in rotary flange (see chapter
3.2).
The flange surface of the rotary flange
fitting must be upright!
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 profile of the pro-
file flange seal must point towards the
rotary flange fitting (see Figure 3).
Prior to plugging in the device, ensure
that the wastewater connection is func-
tional.
Only operate the device in a technically
faultless condition:
1701431 • 2022/01 JUDO JUKOMAT-LF-AT 5
Safety
•Check for damage prior to installa-
tion.
•Immediately have any malfunctions
in operation rectified by qualified
technical personnel.
Persons who, due to their physical, sen-
sory or mental abilities or their inexperi-
ence or lack of knowledge, are unable to
operate the device safely may not oper-
ate it without supervision or instruction
from a responsible person.
Regular backwashing of the device is
required to ensure safe drinking water
hygiene (see chapter 4.3.1).
The mains voltage must not be inter-
rupted (e.g. via a light switch). If the filter
is not permanently supplied with power,
backwashing or a warning in case of
faults is not possible.
Do not use household cleaning agents to
clean the outside of the device, but only
use clear water to avoid embrittlement of
the plastic.
The device may only be repaired by qual-
ified technical personnel.
Only use original spare parts for repairs.
Before performing work on the device
that goes beyond pure operational use,
the device must be depressurised! If
this is ignored, the result may be uncon-
trolled escape of water resulting in water
damage to the building/home.
If the device is removed due to an inter-
ruption of operation:
•Protect the flange surfaces against
damage to ensure proper sealing.
•Protect the device from dirt so as not
to impair drinking water hygiene.
•Store the device in a frost-free place
to prevent damage caused by freez-
ing water and leakage.
Unauthorised conversions and changes
are forbidden for safety reasons. These
can impair the functioning of the device,
leading to leaks and, in the worse case
scenario, to bursting of the device.

2.2 Function description
Unfiltered water flows into the device
through the rotary flange. The water flows
from the outside to the inside through a
cylindrical sieve insert. Dirt particles remain
on the sieve fabric of the sieve insert. The
adhering residues are visible from outside
through the transparent filter bowl.
JUKOMAT-LONGLIFE-AT ¾" - 1¼": The fil-
ter bowl is visible through the viewing slot of
the UV protection screen. The UV protection
screen can be moved downwards to check
the contamination.
The filtered water continues to flow into
the pressure reducer, which regulates the
incoming water pressure to the set down-
stream pressure. The set downstream pres-
sure can be read at the downstream pres-
sure gauge.
Subsequently the filtered water exits the
device again via the rotary flange fitting.
