Instrucciones de limpieza del filtro
Este mezclador viene provisto de uno o dos filtros de acero inoxidable que evitan el ingreso de partículas extrañas a la tubería. Si ha disminuido el caudal
de agua, podría deberse a que los filtros están tapados. Se los puede limpiar de la siguiente manera:
1. Cierre el agua desde la llave de paso (llave angular).
2. a) Para el modelo DEMD-301LF: Desconecte la manguera de la llave de paso y quite la tuerca adaptadora (ver 'Lista de partes').
b) Para el modelo DEMD-311LF: Desconecte las mangueras roja y azul de las llaves de paso y quite las tuercas adaptadoras (ver 'Lista de partes').
3. Quite el / los filtros y enjuáguelos en agua corriente.
4. Rearme las partes.
5. Reconecte las mangueras y reestablezca el suministro de agua.
6. Asegúrese de que no haya pérdidas de agua.
Cuidado y limpieza del cromado y de los acabados especiales
NO EMPLEE lana de acero o agentes limpiadores que contengan alcohol, ácido, abrasivos o similares. El uso de cualquiera de los limpiadores o productos
de limpieza prohibidos podría dañar la superficie del grifo. Para limpiar la superficie del grifo SOLO emplee agua y jabón y luego séquelo con un paño
limpio o toalla. Cuando limpie los azulejos del baño deberá proteger los grifos del salpicado de limpiadores agresivos.

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. To return to normal operation,
remove any blockage.
** 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 completely used up.
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 batteries.
Increase the range.
Decrease the range.
The battery must be replaced.
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 solenoid.
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
solenoid.
Clean or eliminate case of interference.
Decrease the range or eliminate cause
of reflection.
Remove, clean and re-install.
