CHECK CONTENTS
Separate all parts from the packaging and check each part with the “Pack contents”
section.
Pay attention to the dierent 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 electronic faucet until you obtain
the missing parts.
WARNINGS
Do not install facing a mirror or any other electronic system operated by an infrared
sensor.
To prevent reflection problems, it is recommended to keep a minimum distance of .
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 o water supply.
IMPORTANT
All plumbing is to be installed in accordance with applicable codes and regulations.
PRE-INSTALLATION INFO

INSTALLATION

For battery operated versions:
Connect the battery to the
electronic unit connector and
place the battery inside the flush
valve cap.
For transformer operated versions:
a) Pass the electric wires through
the cable compartment located in
the flush valve cap.
b) Connect the electronic unit and
transformer connectors. Make
sure that the connectors are then
located inside the cap.
c) Plug the transformer to the main
electricity supply.

Connect the electronic unit and
solenoid valve connectors and
remove the sticker.

Assemble the cap on the flush
valve body, making sure that the
o-rings are located in between and
tighten the screws.

MANUAL RANGE ADJUSTMENT
The sensor range is the range an object can be away from the sensor in order to activate
the flush valve. The sensor is factory preset. If necessary, it can be adjusted as follows:
Adjusting the sensor range manually:
. Disconnect the battery from the sensor.
. Make a short circuit between the (+) and the (-) of the sensor. You can use a screw driver
or another conductor material to make this short circuit. Alternatively, aer disconnecting
the power supply, activate the sensor three or four times.
Do not make a short circuit on the power supply or on the sensor when the power supply
is connected to the sensor.
. Reconnect the power supply to the sensor.
. To enter into the adjusting mode, put your hand in front of the sensor at a distance of 
“(cm) to ”(cm) within 5 seconds aer the reconnection of the power supply.
NOTE: If you will not put your hand in front of the sensor aer connecting the power
supply, the sensor will not enter into adjusting mode and the previous setting will return.
. When the sensor enters into 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.
. Keep your hand in 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.
. When the red light has turned o, your sensor has been adjusted to the required
distance.
. Check the distance you have set and if it is not satisfactory, repeat steps .

SETTINGS ADJUSTMENT
ADJUSTING THE SETTINGS WITH THE REMOTE CONTROL
If necessary, the sensor settings can be adjusted as following:
Shut o the water supply. In order to adjust the sensor with the remote control, hold the
remote control straight in front of the sensor in a distance of about ”
(cm). Choose the function you want to adjust by pressing once on one of the
function buttons. Aer pressing once on a specic function button, a quick flashing of
the red light at the front of the sensor will occur. At this stage, you can change the setting
by pressing the (+) or the (-) buttons, every push will increase or decrease one level. Aer
nishing the adjustment, turn the water supply back on.

SETTINGS ADJUSTMENT
DETECTION RANGE: The sensor range is the greatest distance that an
object can be away from the sensor to activate the flush valve. The
sensor is factory preset.
To adjust the sensor range, press the RANGE button. Wait until a quick
flashing of the red light of the sensor eye is perceived. Then, press +
to increase the one level and – to reduce it every push will increase or
decrease one level.
FLOW TIME: Changes the flush valve flush time, once the user leaves the
urinal or the toilet. Press + to increase the flow time and – to decrease it.
DELAY IN TIME: It is recommended to change the delay in time for flush
valves for urinals or toilets only.
If required, the delay in time can also be modied in faucets as follows:
Press the IN button. Wait until a quick flashing of the red light of the sensor
eye is perceived. Then, press + to increase the delay in time and – to reduce
it.
DELAY OUT TIME: This button allows modifying the water flow time aer
the user removes his hands from the flush valve. A delay out time close to
0 (zero) will save more water. An increased delay out time will make the
user experience more comfortable.
If required, the delay out time can be modied as follows:
Press the OUT button. Wait until a quick flashing of the red light of the
sensor eye is perceived. Then, press + to increase the delay out time and
– to reduce it.
TEMPORARY OFF FUNCTION: This function is ideal to perform any kind of
activity in front of the sensor without operating the system (for example,
cleaning).
The flush valve will remain shut for 1 minute when this button is pressed
once. To cancel this function and to return to normal operation press the
On/O button again or wait  minute.
RESET BUTTON: This function restores all the factory settings except
for the sensor range. If required, press the Reset button and without
releasing it, press the + button once.

BATTERY REPLACEMENT
When the battery weakens, the red indicator light will blink at a constant rate. The battery
must be replaced within two weeks.
IMPORTANT: Spent batteries should not be disposed of with normal household waste.
Contact your local authority for information on waste disposal and recycling.
NOTE: BEFORE REASSEMBLING THE ELECTRONIC CAP, MAKE SURE THAT THE EXTERNAL
ORING IS NOT DAMAGED. REPLACE IT IF NECESSARY.
Turn o the shut o valve.
Release the flush valve cap screw and
carefully pull it out along with the cap.

Replace the used battery with a
new V battery. A Lithium battery is
recommended.

Disconnect the connector coming from
the electronic unit to the battery.

Tighten the screw.

Reassemble the flush valve cap.
ATTENTION: The interior of the flush
valve body and cap must be fully dry
before reassembling the parts.

MAINTENANCE
Care and cleaning of chrome and special nishes
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 flush valve. For surface cleaning use ONLY soap and water,
then wipe dry with clean cloth or towel. When cleaning bathroom tile, the flush valve
should be protected from any splattering of harsh cleansers.
If system chemical disinfection is practiced, chlorine can be used (calculated chlorine
concentration of 50mg/l maximum in water per one hour dwell time) at service
interval frequency.

** In this case, the water flow will stop anyway aer 90 seconds because of the security time.
SOLUTIONCAUSEPROBLEM
Replace the piston.
1. The self cleaning needle came out of the piston
orice or is displaced. The orice delivers more
water than usual pushing down the piston,
causing the piston to close faster than normal.
Low

Replace the U-seal.
2. The U-seal is torn or damaged and doesn’t seal
well enough.
Increase the flow time.
3. Flow time setting is too short..
Open the piston cover and clean the piston and
body internally.
1. Debris or dirt in the Flush Valve clog up the piston.
Friction in the piston movement causes the piston to
close slower than normal.
High
Discharge
Open the piston cover and clean the piston and the
orifice.
2. Dirt in the piston orifice prevents enough water from
going through the orifice. The reduced flow causes the
piston to close slower than normal.
