PRE-INSTALLATION INFO
Check contents
Separate all parts from the packaging and check each part with the pack
contents section. Pay attention to the variations of the different models.
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.
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.
Warning
To avoid reflection problems keep a distance of more than 300 mm.
between the sink and the spout.
1. Keep a distance of more
than 300 mm. between the
sink and the spout.
To avoid reflection problems
2. Do not place a shiny
pop up in front of the
sensor.

FAUCET INSTALLATION D28
Step 1 – Installing the faucet
1. Shut off the water supply
2. Drill a hole (23 to 24 mm) at the place where you want to install the spout of
the tap.
3. Your model includes an optional anti-rotation pin. Drill a small hole just above
the previous one for the anti-rotation pin.
4. Insert the D28 and its attachments through the wall. The aerator in the D28
spout must face the washbasin.
5. Insert the anti-rotation pin into the small hole (if needed)
6. Fix the base behind the wall with the hexagonal nut and the disk.
Step 2 - Connecting the water supply
1. Fit the flexible pipe coming from the D28
base to the solenoid valve housing.
2. Fit the water supply inlet to the inlet nipple
at the solenoid valve housing.
Note: Make sure the filter is located at the
solenoid inlet.
3. Connect the cable coming from the electronic
unit to the solenoid valve.
Important: D28 was supplied with a Self Adjusting
Sensor. The ideal sensor range for the specific
location will be set automatically.

FAUCET INSTALLATION D28
Before proceeding to step 3 check that
no objects are in front of the sensor
besides the washbasin.
Now, remove the protecting sticker that
covers the sensor.
Step 3 – Connecting the power source
1. For D28 B: Connect the other cable coming from the electronic unit at the D28
base to the battery box.
2. For D28 E: Connect the other cable coming from the electronic unit at the D28
base to the transformer. Plug the transformer into the electricity socket.
3. After you have connected the power source
(Battery or Transformer) wait 15 seconds in order
to allow the system to set the ideal sensor range.
As an indication that the self adjusting is taking
place, a red light in the sensor eye will flash
continuously. The solenoid valve will be opened
and closed for 1 second as an indication that the
ideal sensor range was set and the product is
ready for use.
4. Turn on the central water supply. Check for
leaks.
5. If the automatically adjusted sensor range is
not satisfactory, please refer to the section entitled “Settings adjustment”.

FAUCET INSTALLATION D28 DUAL POWER
Step 1 – Installing the faucet
1. Shut off the water supply
2. Cut an adequate opening in the wall for the dimensions of the D28 base (where
you want to install the spout), and the corrugated tube.
3. Install the D28 dual power base and its attachments through the opening that
was cut in the wall.
4. Mount the D28 base to the opening cut in the wall, and set
it using the two small anchors provided. (See FIG. 1)
Important: The D28 base should be installed so that the
outside surface of the finished wall falls between the
minimum and maximum lines marked at the base.
5. Assemble the temporary protective D28 base cover.
(See FIG.2)
6. Make sure the corrugated tube will stay
outside the wall when tiling.
7. Once the works on electricity, plumbing
and tiles have been finished, insert the
wall rosette through the D28 base.
8. Cut the temporary D28 base cover.
9. Pull the four way connector out of the D28 base, and lead
it along with the flexible tube, through the corrugated tube.
10. Connect the flexible tube to the solenoid valve body
integrated in the dual power input box. (See FIG.3)
11. Fix the D28 spout by inserting the nipple into the D28 base
and tighten the screw.
OPERATION:
This faucet features an IP67 dual power input box. The product can be operated
with a 9V battery or a 9V transformer. In addition, when used with a transformer,
the product contains an integrated battery back up, for normal use during power
supply failures.
