PRE-INSTALLATION INFO
Check contents
Separate all parts from the packaging and check each part with
the “Pack contents” section.
Pay attention to the different models variations.
Make sure all parts are accounted for before discarding any
packaging material.
If any parts are missing, do not attempt to install your Extreme
electronic faucet until you obtain the missing parts.
Warnings
Do not install the system facing a mirror or any other electronic
system operated by an infra-red sensor.
To prevent reflection problems, it is recommended to keep a
minimum distance of 1.50 meters between the faucet and any
other objects.
Preparation for installation
Flush water supply lines thoroughly before installing the faucet. Do
not allow dirt, Teflon tape or metal particles to enter the faucet.
Shut off water supply.
Important
All plumbing is to be installed in accordance with applicable
codes and regulations.

FAUCET INSTALLATION
Step 1 – Preparation for mounting
the faucet
Shut off water supply and remove
the hexagonal nut, the disk and the
gasket. Do not remove the O-ring
from the base of the faucet.
Step 2 – Installing the
faucet
1. Place the faucet with
O-ring into the hole in the
deck or lavatory. Make
sure the O-ring is located
between the deck or
lavatory and the bottom of
the faucet.
2. Slide the gasket over
flexible hose(s).

FAUCET INSTALLATION
Step 3 – Connecting the water supply
1. a. Connect the flexible pipe to the
water supply.
b. For models with temperature control
connect the red flexible pipe to the hot
water supply and the blue flexible pipe
to the cold water supply.
2. Make sure that the filter(s) is/are
installed between the flexible pipe and the
shut off valve (angle valve) (not supplied).
3. Turn on the central water supply and
the shut-off valves (angle valves).
4. Check for leaks.
Step 4 - Connecting the power source
1. Connect the power source:
a. For battery versions: install the battery’s box at the wall underneath the sink using
the two sided adhesive foam faucete. The cable connection must point down. (You
can use an optional extension cable in order to assemble the battery box up to 10ft.
away from the sink. See section ”Spare parts”)
b. For transformer versions: Plug the transformer into the electricity socket and
connect the connectors.
2. Wait a few seconds before
activating the faucet.
3. If the range is unsatisfactory,
refer to the section titled “Range
adjustment”.

RANGE ADJUSTMENT
The sensor range is the greatest distance that an object can be away from the
sensor to activate the faucet. The sensor is factory preset. If necessary, it may
be adjusted as follows:
Adjusting the sensor settings with a remote control – optional and
recommended:
The sensor range is the greatest distance that an object can be away from the
sensor to activate the faucet. The sensor is factory preset. If necessary, it may
be adjusted as follows
In order to adjust the sensor with a Remote Control you should hold the Remote
Control straight in front of the sensor in a distance of about 4”(10cm). Choose
the function you want to adjust by pressing once on one of the function buttons.
After pressing once on a specific function button, a quick flashing of the red light
in front of the sensor will occur. At this stage, you can change the adjustment
by pressing the (-) or (+) buttons, every push will increase or decrease one
level. After finishing the adjustment, turn on
the water supply.
Range: Press + to increase detection range
and – to decrease the detection range of the
sensor.
The remote control can also be used to
adjust:
Flow time (Security time): Press + to increase
the security time and – to decrease it.
Delay In: Changes the time the water will start
flowing when the user’s hands are within the sensor range. Press + to increase
it and – to decrease it.
Delay Out: Changes the time of water flow after the user’s hands are removed.
Press + to increase it and – to decrease it.
On/Off: Press this function button and the faucet will remain off for 1 minute. To
cancel this function press the on/off again.
Reset: This function allows to come back to all the factory settings. Press the
Reset button and without releasing it, press one time the + button.

RANGE ADJUSTMENT
NOTE: Adjust only if necessary.
Adjusting the sensor range without remote control:
1. Disconnect the power supply, battery or transformer, from the sensor.
2. Activate the sensor three or four times.
3. Reconnect the power supply to the sensor.
4. To enter into the adjusting mode, put your hand in front of the sensor at a
distance of 2”(5cm) to 4”(10cm) within 5 seconds after the reconnection of the
power supply.
Note: If you will not put your hand in front of the sensor after connecting the
power supply, the sensor will not enter into adjusting mode and the previous
setting will return.
5. When the sensor enters into the adjusting mode and your hand is in front of
the sensor, a slow flashing of the red light at the front of the sensor will occur.
6. Keep your hand at the front of the sensor until the slow flashing changes into
quick flashing. At this point, move your hand to the required distance from the
sensor and wait until the red light will stop flashing.
7. When the red light has
turned off, the sensor
has been adjusted to
the required distance.
8. Check the distance
you have set and if it is
not satisfactory, repeat
steps 1-6.
sensor and wait until the red light will stop flashing.

MAINTENANCE
Filter cleaning instructions
This faucet is provided with one / two stainless steel filter(s) preventing foreign
particles to enter the lines. If the water flow has decreased, this can be because
the filter(s) is/are clogged. The filter(s) can be cleaned as follows:
1. Shut-off the water shut off valve (angle valve).
2. Disconnect the flexible pipe/s.
3. Remove the filter(s) and wash it/them under running water.
4. Reassemble the parts.
5. Make sure that there is no water leakage.
Care and cleaning of chrome and special finishes
DO NOT use steel wool or cleansing agents containing alcohol, acid, abrasives, or
the like. Use of any prohibited cleaning or maintenance products or substances
could damage the surface of the faucet. For surface cleaning of faucet use
ONLY soap and water, then wipe dry with clean cloth or towel. When cleaning
bathroom tile, the faucets should be protected from any splattering of harsh
cleansers.

Low battery.
1. Range is too short.

3. Battery is completely used up
4. Unit is in “Security Mode”*
5. Sensor is picking up reflections from
the washbasin or another object.
1. Connectors between the electronic
unit and solenoid are disconnected.
2. Debris or scale in solenoid.

is plugged or the diaphragm is torn
4. The water supply pressure is higher
than 8 bar.
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
backcheck prevents from dropping,
even after water supply pressure drops
under 8 bars.
Debris or scale in diaphragm
1. Sensor is dirty or covered.**
2. Sensor is picking up reflections from
the washbasin or another object.
Filter or aerator is clogged
Replace battery.
