TROUBLESHOOTING
Problem
No water coming out of the
faucet.
Water flow from spout does
not stop.
Water flow diminished.
* "Security Mode": If the sensor is covered for more than 90 seconds, the faucet will automatically shut off water flow.
** Water flow will stop after 90 seconds because of the security time.
Indicator
1. Sensor flashes continuously when
user's hands are within the
sensor's range.
2. Red light in the sensor does not
flash when user's hands are
within the sensor's range.
3. Red light in the sensor flashes
when user's hands are within the
sensor's range.
1. Sensor flashes when user's hands
are within the sensor's range.
2. Red light in the sensor does not
flash when the user's hands are
within the sensor's range.
Cause
Low battery.
1. Range is too short.
2. Range is too long.
3. Battery is fully drained.
4. Unit is in "Security Mode"*.
5. Sensor is picking up reflections
from the mirror or other object.
1. Connectors between the electronic
unit and solenoid are disconnected.
2. Debris or scale in solenoid.
3. The central orifice in the diaphragm
is plugged or the diaphragm is torn.
4. The water supply pressure is higher
than 116 PSI (8 bars).
5. The water supply pressure is under
116 PSI (8 bars) and yet the press-
ure 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
the water supply pressure drops
under 116 PSI (8 bars).
Debris or scale in diaphragm or the
diaphragm is torn.
1. Sensor is dirty or covered.**
2. Sensor is picking up reflections
from mirror or another object.
Filter or aerator is clogged.

Solution
Replace battery.
Increase the range.
Decrease the range.
The battery must be replaced.
Remove any blockage to return to
normal operation.
Eliminate cause of reflection.
Connect the electronic unit connectors
to the solenoid.
Unscrew solenoid, pull out the plunger
and the spring from solenoid and clean
them. Use scale remover material if
needed. When replacing the plunger,
please make sure that the spring is in
the vertical position.
Clean the orifice or replace diaphragm.
Reduce the water supply pressure.
Shut off water supply and unscrew one
of the flexible pipes in order to reduce
the pressure that blocks the product.
Clean the orifice or replace the
diaphragm.
Clean or eliminate case of interference.
Decrease the range or eliminate cause
of reflection.
Remove, clean and re-install.
