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.
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 LK app and Wi-Fi 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 sys-
tem.
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 counter-
hold.

Preparing for installation
The water safety system must be installed by a
plumber according to the Safe Water Installation
industry regulations.
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 after-
wards, 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
also be connected before [word missing] to
avoid interfering with its function. The system
prevents water damage that may occur after
the position of the water safety system.

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

The picture on the left shows an open valve, a closed valve
is shown on the right.
Operation
Follow the unit’s measurements via the LK app.
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. If a fault occurs during operation, the
water safety system will emit an alarm and close
the valve.
Measured values from the water safety system are shown in
the LK app.
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.
Manual
1. To deactivate the alarm function, press and
hold down the Water ON/OFF button
for at least ve seconds.

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 LK app is tem-
porarily interrupted, and it then does not receive
notications or alarms until contact is established
with the Internet
Environment
LK Systems is afliated with El-Kretsen for col-
lecting and recycling electronics and batteries.
Used batteries should be sorted as batteries or
small batteries and deposited for battery recy-
cling. When the system has reached the end of
its life, it should be sorted as electronics or other
electronics and deposited with a recycling centre.
