* “Security Mode”: If the sensor is covered for more than 90 sec. the faucet will automatically shut off
water flow.
To return to normal operation remove any blockage.
** In this case, the water flow will stop anyway after 90 seconds because of the security time.

Replace battery
Low battery.
1. Sensor flashes
continuously
when user’s
hands are within
the sensor’s
range.
No water
coming out
of the faucet:
Increase the range
1. Range is too short.
2. LED in the
sensor does not
flash once when
user’s hands
are within the
sensor’s range.
Decrease the range
2. Range is too long.
The battery must be replaced.
3. Battery is completely used up
4. Unit is in “Security Mode”*
Eliminate cause of reflection.
5. Sensor is picking up reflections from the
washbasin or another object.
Connect the electronic unit
connectors to the solenoid.
1. Connectors between the electronic unit
and solenoid are disconnected.
3. LED in the
sensor flashes
once when
user’s hands
are within the
sensor’s range.
Unscrew solenoid, pull out the
plunger and the spring from
the solenoid and clean them.
Use scale remover material if
needed. When replacing the
plunger, please make sure that
the spring is in vertical position.
2. Debris or scale in solenoid.
Clean the orifice or replace
diaphragm.
3. The central orifice in the diaphragm is
plugged or the diaphragm is torn
Reduce the supply water
pressure.
4. The water supply pressure is higher than
8 bar.
Shut off water supply and
unscrew one of the flexible
pipes in order to reduce the
pressure that blocks the
product.
5. The water supply pressure is under 8 bars
and yet the pressure in the faucet’s body is
higher. This situation could be caused by a
sudden increase in the water supply pressure
that the back check prevents from dropping,
even after water supply pressure drops under
8 bars.
Clean the orifice or replace
diaphragm.
1. Debris or scale in diaphragm
1. Sensor flashes
once when
user’s hands
are within the
sensor’s range.
Water flow
from spout
does not
stop:
Clean or eliminate case of
interference.
1. Sensor is dirty or covered.**
2. LED in the
sensor does not
flash once when
user’s hands
are within the
sensor’s range.
Decrease the range or eliminate
cause of reflection.
2. Sensor is picking up reflections from the
washbasin or another object.
Remove, clean, re-install
Filter or aerator is clogged
Water flow
diminished
