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 intended to shut off the water
supply to drinking water systems, upon
exceeding of the settable values for
•maximum withdrawal time
•maximum water quantity
•maximum water volume flow
for protection against water damage, water
loss and unwanted water consumption.
It can be installed in all commercially avail-
able drinking water pipes. Installation and
use are subject to the applicable national
conditions.
1.2 Application limits
1.2.1 Water quality
The water must comply with the European
Drinking Water Directive (98/83/EC). Before
using the device with water that does not
comply with this Directive, it is essential to
consult the manufacturer.
1.2.2 Water pressure
CAUTION
The water pressure must not exceed
16 bar input pressure. The device
must not be installed if the mains
pressure is above 16 bar (even for a
short time)!
Nominal pressure PN 16
1.2.3 Water and ambient tempera-
ture
The filter is suitable for use in cold drinking
water up to a maximum water and ambient
temperature of 30 °C.
1.3 Safety instructions
DANGER
The device could reduce or cut
water supply for equipment down-
stream requiring constant readi-
ness for water withdrawal (e.g.
thermal flow protection, sprinkler
system).
This could result in fires or explo-
sions.
If there are downstream safety
devices and the water supply line
to these devices does not branch
off upstream of the device, then
the device must not be installed!
DANGER
The motorised ball valve is
installed on the rear side of the
device. When the device is not
installed, the ball valve can be
reached with the finger through the
opening on the rear.
If the device is commissioned or
connected to the mains without
being installed, there is a risk of
crushing due to rotating parts.
Never operate the device or con-
nect it to the electrical mains if it is
not fully installed!
Never put your finger in the open-
ing on the rear side of the device!
4 JUDO JPCS 1703593 • 2022/10

Safety
1.3.1 Electrical danger
ELECTRO_NO_HEADER
Risk of electric shock
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 24 V.
A splash-proof socket above the device,
at a distance of no more than 1.5 m, is
required for connection to the mains, in
accordance with the legal regulations for
wet rooms.
The power supply unit must be discon-
nected to make the electrical installation.
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.
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 device in order to
interrupt the water supply during instal-
lation, maintenance, repair or malfunc-
tion of the device.
For the installation of the device in
domestic water piping, only use the sup-
plied built-in rotary flange (see chap-
ter(siehe Kapitel 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 (siehe Figure 4).
Only operate the device in a technically
faultless condition:
•Check for damage prior to installa-
tion.
•Immediately have any malfunctions
in operation rectified by qualified
technical personnel.
The appliance must not be exposed to
strong vibrations.
The mains voltage must not be inter-
rupted (e.g. via a light switch). If the
device is not permanently supplied with
power,
•a possible leakage cannot be
detected.
•the leakage protection cannot close
in the event of a leakage.
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.
After the leakage protection has closed
due to a limit being exceeded, first check
whether there is a leak before opening
the leakage protection again.
If there is a device for hot water prepa-
ration (in particular a gas or electrically
operated instantaneous water heater
or a heating boiler), the manufacturer's
instructions for the water heater must
1703593 • 2022/10 JUDO JPCS 5

Safety
be observed before opening the leakage
protection (instructions for venting).
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.

4.3.5 Micro leakage testing, manual
or automatic
The device also has the option of being able
to promptly detect small leaks.
Micro leakage testing can be started man-
ually at any time (see Starting micro leak-
age testing manually, page 19), but can
also take place automatically (see Perform-
ing small leakage testing automatically,
page 17).
If the leak cannot be found, even though a
micro leakage is repeatedly detected, the
installer or a professional company should
carry out a leak detection on the installation,
in order to find any possible leaks.
INFO_NO_HEADER
Automatic micro leakage testing is
deactivated upon delivery and can be
activated if desired.
If automatic micro leakage testing is
activated with subsequent setting to
message and closing of the water
supply, it is possible that frequent
shutting off of the water supply can
occur because, based on experience,
very small leaks are not an infrequent
occurrence.
A preceding period of at least one
hour without any water flow is neces-
sary so that a micro leakage test can
run.
Performing small leakage testing
automatically
Micro leakage testing can also be per-
formed automatically; in this case testing is
performed daily without anything further to
do.

Micro leakage testing can be
started manually at any time
even when a regular automatic
test had been set.
Prerequisite for automatically
running micro leakage testing is a
period of
at least one hour, in which no
water withdrawal takes place.
4.4 Setting limit values
Exceeding of the set limit values for
•maximum water quantity
•maximum water flow
•maximum water withdrawal time
leads to shutting off of the water supply.
INFO_NO_HEADER
When setting the limit values, con-
sideration must be given to devices
that depend on a sometimes very low
continuous water supply over a long
period of time to ensure their proper
functioning (e.g. certain tumble dry-
ers, etc.).
It is also possible to operate such
devices using sleep mode of the
micro leakage protection system.
