Determine the desired mounting location of the Sensor Faucet and Solenoid Box.
Mark appropriate locations on the vertical studs of the wall.
Draw a level line across the two (2) Vertical Studs as shown.
The distance between the Sensor Faucet and
Solenoid box must not exceed 33”
Cut three (3) 2”x 4” Horizontal Braces to fit between the Vertical Studs.
The two (2) Upper Braces shall each be installed 1 1/2” from the centerline of the
desired Sensor Faucet location. The Lower Brace shall be installed 2” above the
centerline of the desired Solenoid location. Secure Horizontal Braces to Vertical Studs.
(Mounting hardware not included)
Use PVC piping (metal pipe/hoses can’t be used with the
sensor as it causes interference)

Secure the connector and wire and use a
1/2” PVC Connector [nipple] to ensure
the 1/2” male connection is accessible
after tiling.
Based on the thickness of wall/dry-
wall/tile get a suitable PVC connector.
The connector that fits into the Curve

TURN OFF THE WATER SUPPLY
Turn off the water supply before intervening
with the faucet or plumbing.
INSTALL GUIDELINE
For installation with metallic sinks, make sure that a plastic
mounting ring is placed between the faucet and the sink.
The body of the faucet must be well electrically isolated
from the sink.
Ensure that the faucet’s pipe thread is not in contact with the sink.
Install the electrode washer under the sink, between the nut and
the rubber spacer. The electrode washer cannot be in contact
with a metallic sink.
The electrode washer must be in contact with the faucet, to ensure
optimum detection. Connect the sensor cable to the electrode washer.
In the case of a metal sink, the sink must be grounded

SECURE THE BOX
Start by determining the correct position for the box:
Ensure that its position allows you to make the hydraulic connections without creating
unnecessary stress on the water supply hoses. Check that the sensor wire will be able
to reach the electrode washer underneath the faucet.
Make sure that the box will not bear the weight of the water hoses or be placed under
strain by the installation.
Once this has been checked, hold the box in place in the optimum position. Use a pencil to mark
the position of the box’s screw channels (C) on the wall.
Remove the box from the wall then drill and install the screws at the points marked on the wall.
Fix the box to the wall.

ATTACH THE WATER HOSES TO THE VALVE
A - Attach water hose to the valve’s inlet.
B - Attach water hose to the valve’s outlet.
The Sensor Box has standard 1/2" connections. Water tightness is
guaranteed by a flat seal placed between the valve thread and the
hoses: ensure that seals have the correct dimensions, are clean and
without defect, whilst checking that the seals are fit for purpose.
Do not clamp the box inlet or outlet with a wrench or other tools in order
to avoid damage to the body’s exterior surface and premature wear of
internal components.
Replace the valve in the box according to the pictogram on the base of the box
INSTALL THE SOLENOID VALVE
Replace the valve in the box according to the PICTURE
on the base of the box.
The valve’s position in the box varies depending on the
configuration type: single flow, premix or dual flow (see visual).
Once the valve is securely placed in the box, connect the solenoid
valve’s cable to the box’s corresponding red and black cable.

CONNECT THE SENSOR CABLE
The sensor cable cannot touch any other conductive material
including any sort of metal objects.
The sensor cable should not be coiled.
Ensure that the sensor cable is not stretched or in contact with the
water hoses.
INSERT AND CONNECT BATTERIES
Place 6 AA batteries in the battery holder
according to polarity.
Place the battery holder in the box.
Plug the battery holder cable to the corresponding
connector in the box (black and grey cable).

OPEN THE WATER SUPPLY
Open the water supply, allowing wate to flow into the valve.
Water may start to flow from the faucet if the solenoid
valve’s position is open at the time of installation.
CLOSE THE BOX
Check that there are no water leakages near the hoses,
faucet and valve. Then close the box cover.
You can use the 2 screws to hold the cover in place
for anti-vandal purposes.

CALIBRATION
After connecting the battery holder, the led is green.
Press the button to launch the calibration. Make no contact
with the faucet, box or any components of the installation.
During calibration, the green led flashes and water flows
from the faucet for 10s. Once the water has stopped flowing,
touch the faucet and maintain contact only with one finger
until the water flows again.
The water stops flowing automatically in less than 1s. If the
calibration is successful, the green light stops flashing
and the faucet releases a short burst of water (<1s).
If the calibration is unsuccessful, the box’s red led lights up and the faucet releases two short bursts
of water. In this case, unplug and reconnect the box’s batteries in order to reinitialise the calibration
process.

ADJUST SENSITIVITY IF NECESSARY
After the calibration phase, activate and deactivate the
faucet 3 to 4 times. This should allow the sensor to
automatically optimise sensitivity to its installation
conditions but if the sensor sensitivity is not satisfactory
press the button to adjust it.
The sensor has 3 levels of sensitivity:
Level 1: low
Level 2: medium
Level 3: high
The level of sensitivity can be set by using the button.
• To enter sensitivity adjustment press the button for 3 seconds (until the led flashes).
• Release the button.
• The sensitivity level is indicated by a series of flashes. For example, level 2 is indicated by 2 flashes.
• Each time the button is pressed the sensitivity level increases by 1. At level 3, press once more and
the system returns to level 1.
• After adjusting the level, press the button for 3 seconds to validate. Both leds flash once to confirm
that the sensitivity level has been validated.
• After adjustment the system reboots and restarts an auto calibration cycle. If the sensitivity level is
not validated, the led continues to flash for 25 seconds before stopping without saving the new
sensitivity level

LOW BATTERY
When batteries reach a low level the box’s red LED blinks every
5 seconds. The batteries are nearly empty and need to be
changed quickly before the system shuts off. It takes on
average 10 days for the system to go from low battery to shut off.
MANUAL OVERRIDE
To continue using the faucet manually when the batteries are
empty, press the control button. The faucet can now be opened
and closed by using the faucet’s handle alone. Once the batteries
have been replaced, normal sensor operation resumes
automatically.
Manual override is available for up to two weeks after ther box’s
batteries are empty.
FILTER MAINTENANCE
Depending on the installation’s water quality it may be necessary
to clean or replace the box’s valve filter.
FILTER CLEANING
Remove the valve from the box, Run water into the valve’s inlet
Whilst tilting the valve to the side to allow impurities to pour out
into the sink.
FILTER REPLACEMENT
Remove the valve from the box. Use a pair of tweezers to remove
the filter from the valve. Put an identical filter in place with the filter
grill facing outwards. Push the filter into the valve up until the
mechanical stop.
