TROUBLESHOOTING
* “Security Mode”: If the sensor is covered for more than 90 sec. the outlet 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.
SOLUTION
CAUSE
INDICATOR
PROBLEM
Replace battery
Low battery.
1.Sensor flashes
continuously when
user’s hands are
within the sensor’s
range.
No water
coming out
of the outlet:
Increase the range
1. Range is too short.
2. LED in the sen-
sor 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.
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.
1. Debris or scale in solenoid.
3. LED in the sen-
sor flashes once
when user’s hands
are within the sen-
sor’s range.
Clean the orifice or replace
diaphragm.
2. The central orifice in the diaphragm is
plugged or the diaphragm is torn
Reduce the supply water pres-
sure.
3. The water supply pressure is higher than
8 bar.
Shut off water supply and un-
screw one of the flexible pipes
in order to reduce the pressure
that blocks the product.
4. The water supply pressure is under 8 bars
and yet the pressure in the outlet’s body is
higher. This situation could be caused by a
sudden increase in the water supply pressure
that the backcheck 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:
Connect the connectors prop-
erly. Refer to pages 8/13/17 to
see how.
2. Connectors between the electronic unit and
the Dual power input box are disconnected or
not connected properly
Clean or eliminate case of
interference.
1. Sensor is dirty or covered.**
2. LED in the sen-
sor 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
