Design
LK CubicSecure is a water safety system that pro-
tects against leakage by continuously measuring
water consumption, water pressure and tempera-
ture. The unit emits alarms for both micro-leaks
and larger leaks. When the water safety system
detects a leak, it automatically shuts off the water
ow. The water circuit breaker can be installed in
villas, terraced houses and apartments (1).
System description
LK CubicSecure is a small unit that is easy to
install in conned spaces. The unit is easily in-
stalled on incoming water pipes for a house or
apartment. The water safety system is equipped
with a switch for manual shut-off in the event of
power failure or emergency.
NOTE!
Two water safety systems can be paired in
order to avoid scalding in apartments. Pairing
provides a synchronised automatic shut-o󰀨
between the hot and cold water pipes.
With the MyLK app and Wi connectivity, you can
remotely control the unit to shut the water off or
on, acknowledge alarms and monitor your water
consumption, for example.

Installation
1. Install the water safety system on the in-
coming water pipe directly after the water
meter isolation valve and any check valve.
2. Tighten the couplings without damaging the
plastic casing on the water safety system.
The water safety system and the incoming water pipe.
TIP! The water safety system is equipped with a
counterhold on the underside. Use an adjustable
wrench on the counterhold. It is also possible to use
a screwdriver in the slot to create a counterhold.

Preparing for installation
The water safety system must be installed by a
plumber according to the Safe Water Installation
industry regulations.
The water circuit breaker must be installed in a
location that is easily accessible for service and
maintenance.
TIP! The water safety system is equipped with
a G20 EuroCone external thread which is to be
installed with an LK PressPex press connection
coupling or LK Pusht AX connection coupling.
When using a at gasket, LK Plain Adapter is
supplied (RKS-187 06 78) with the product.
NOTE!
Safety systems such as residential sprinklers
and emergency cooling of solid fuel boilers or
similar must be connected before the water
safety system. If they are installed afterwards,
they risk being left without a water supply.
NOTE!
Install the water safety system after supplying
safety systems that require water.
NOTE!
Water lters that are backwashed should be
connected rst so that their function is not dis-
turbed. The system prevents water damage that
can occur after the location of the CubicSecure.
NOTE!
When installing metal pipes in the distributor cabi-
net, the pipe must be provided with an electrical
protective equalization (earthing) which must be
installed by a qualied electrician unless the earth
screw is already in the cabinet.

Connecting to Wifi (1)
Remote monitoring of the unit's measurements
and alarms via a smartphone requires an app and
a connection to a Wi network with a frequency
of 2.4 Ghz.
1. Download and install MyLK-app from App
Store or Google Play Store.
2. Start MyLK-app and log into the app.
3. Follow the instructions in MyLK-app.
The login page for the MyLK app.
PAIRING
Example cabinet with pairing.
Startup
1. Connect power to the unit using the micro-
USB power adapter included.
The water safety system connected to the power source.
2. Check that the STATUS LED is WHITE.
White light indicates that the device is oper-
ating normally when CubicSecure is installed
on a water-lled pipe. If not installed on a
pipe lled with water, the unit will not glow
WHITE. If no LEDs light up, check that the
wall outlet or power adapter is functional.
White light - the unit is working normally.

Start-up and function check
Check that the ball valve is working
1. Press the WATER ON/OFF button.
The LED stops lighting when the ball valve
has completely shut off the water ow.
2. Open a tap. Check that no water comes out
of the tap.
3. Press the WATER ON/OFF button.
The LED shines with a white light when the
valve is fully open. Check that water is now
coming out of the open tap. During active
waterow the LED ashes white.
Check that the pressure sensor is working
1. Open a tap to simulate a very small leak. A
dripping stream of water will sufce.
2. Press the WATER ON/OFF button to close
the valve.
• When the valve is closed, the STATUS
LED will ash GREEN while the pressure
sensor scans for small leaks for about 45
seconds.
• If the pressure sensor manages to nd a leak,
the STATUS LED starts ashing YELLOW.
If the pressure sensor does not nd a leak,
redo the steps with a slightly larger leak.
3. Close the tap and press the WATER ON/
OFF button to open the valve again.
Leakage control with flow
1. Open a tap with the valve in the open position.
2. Leave the valve at full ow on the tap for at

Use of large amounts of water
The abnormal ow alarm function can be deac-
tivated if a larger amount of water is needed to
ll a pool or for irrigation. The preset time is 24
hours. The deactivation of the alarm can be done
in the MyLK app or manually.
Manual
1. To deactivate the alarm function, press and
hold down the Water ON/OFF button
for at least ve seconds.
WATER ON/OFF button and yellow LED for the function.
Maintenance
Check the opening and closing function of the valve
1. Press the WATER ON/OFF button.
• The button shines WHITE when the valve
is open.
• The LED is off and dark when the valve is
closed.
• The switch at the top of the unit must
rotate and break the line when closed and
follow the line when open.
The picture on the left shows an open valve, a closed valve
is shown on the right.
Alarm
Micro leakage
• A micro leakage is detected by the valve
being automatically closed daily to measure
a pressure drop above 0.5 bar for a maximum
of 45 seconds.
Medium-sized leakage
• The unit alarms and shuts off the water after
a continuous ow for at least 45 minutes.
Large leakage
• The device alarms and closes the valve after
a continuous ow over 1500 l/h for at least
90 seconds.
Acknowledge alarms
• Press the WATER ON/OFF button once to
acknowledge the alarm.
• Press the WATER ON/OFF button again to
open the valve.
Note that an acknowledgment resets all
ongoing leak detections.
Reset WiFi settings
1. Reboot the unit using the power cable and
press the CONNECT button once when the
unit boots up.
Factory reset of the unit
1. Firstly, insert a paper clip into the hole
on the reset button while plugging in the
power cable during 3 seconds.
2. Wait about three minutes. After about three
minutes, the unit has reset and the LEDs
light up again.
Operation
Follow the unit’s measurements via the MyLK app(1).
Various data such as temperature, volume, water
pressure, valve position and no leakage detected
are displayed for each unit. When LK CubicSe-
cure is in operation, it performs automatic leak-
age tests and exercise the valve. If a fault occurs
during operation, the unit will emit an alarm and
close the valve.

Comment
Completely interference-free operation cannot always
be guaranteed with the technology available today,
which allows free use of the frequency band.
Every installation should therefore be tested indi-
vidually. LK CubicSecure always works indepen-
dently. The water safety system will still work if
the unit loses contact with the Internet. The unit is
still in operation and emits an alarm when a leak
is detected. The contact with the MyLK app is
temporarily interrupted, and it then does not re-
ceive notications or alarms until contact is estab-
lished with the Internet
