PRE-INSTALLATION INFO
CHECK CONTENTS
Separate all parts from packaging and check each part with the pack contents section.
Make sure all parts are accounted for before discarding any packaging material. If any
parts are missing, do not attempt to install the electronic flush valve until you obtain

WARNINGS
Do not install the system facing a mirror or any other electronic system operated by an
infrared sensor.
To prevent reflection problems, it is recommended keep a minimum distance of
1.50 meters between the flush valve and other objects.
PREPARATION FOR INSTALLATION
Flush water supply lines thoroughly before installing the flush valve. Do not allow dirt,
Teflon tape or metal particles to enter the flush valve.
All plumbing is to be installed in accordance with applicable codes and regulations.

(15-20cm). 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
WITH REMOTE CONTROL
FLOW TIME: This function determines the water flushing time once
the user leaves the urinal.
Press the two waves button. Wait until a quick flashing of the red
light of the sensor eye is perceived. Then, press + to increase the
flow time and – to reduce it.
DELAY IN TIME: If required, the delay in time can be modied 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 changes the time interval the water
starts to flush aer the user has le the urinal.
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.
 HOUR HYGIENE FLUSH: If you have a compatible model with a 24
hours hygiene flush it is possible to enable and disable it.
To activate the hygiene flush, press the clock button. Wait until a
quick flashing of the red light of the sensor eye is perceived. Then
press + to activate the hygiene flush or – to deactivate it.
TEMPORARY OFF FUNCTION: This function is ideal to perform any

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 or switch o the electricity supply to the sensor.
. Present your hand in front of the sensor and ensure it blinks once. If the sensor
does not blink, proceed to step 3. Hold your hand in front of the sensor
for 10 seconds.
. 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) within  seconds from the re-connection 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 the adjusting mode and the previous adjustment
will continue.
. When the sensor enters into the adjusting
mode and your hand is in front of the sensor,
the red light in front of the sensor will flash
slowly.
. Keep your hand in front of the sensor until
the slow flashing changes to 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, the sensor
is adjusted to the required distance.
. Check the distance you have set and if it is
not satisfactory, repeat the procedure.

MAINTENANCE
Filter cleaning instructions
This flush valve is provided with a stainless steel lter preventing foreign particles
to enter the lines. If the water flow has decreased, this may be because the lter is
clogged. The lter can be cleaned as follows:
. Turn o the regulating valve.
. Disassemble the solenoid valve by opening the nuts.
. Remove the lter and wash it under running water.
. Reassemble the lter.
. Reassemble the solenoid valve.
. Turn on the regulating valve and adjust the flow capacity.
. Make sure that there is no water leakage.
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.
