PRE–INsTallaTION INFORMaTION
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 your Touch 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.
FAUCET INSTALLATION
Step 1 – Remove all mounting hardware
1. Shut off the 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 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 the flexible hose.
3. Secure the faucet to deck or lavatory with the
hexagonal nut and the disk.

Step 3 – Connecting the water supply
1. Fit the pipe to the housing of the solenoid valve. Important: inlet and outlet
should follow the indicating arrow at the solenoid housing.
2. Fit the water supply inlet to the adapter at the solenoid valve housing.
Note: Make sure that the filter is assembled between the housing of the solenoid
valve and the adapter.
Step 4 – Connecting the power source
1.For Touch B: Install the battery box at the wall under the sink using the screws or
the two sided adhesive foam tape.
For Touch E / BRE: Plug the transformer into the electricity socket.
Important: In order to avoid entering into the adjusting mode, wait 10 seconds
before operating the system.
2. Turn on the central water supply and the shut-off valves.
3. Check for leaks.
FLOW TIME ADJUSTMENT
Adjustment levels
The flow time is programmable on site. If necessary, the default flow time of
8 seconds can be adjusted to any value between 1 to 60 seconds. The Touch
adjustment mechanism is composed of 3 adjustment levels for changing the flow
time. An indicator light (LED) will guide you from one level to the other.
The following table shows the number of steps in each level, the duration of each
step and how to recognize in what adjusting level you are.
Level 1 Level 2 Level 3 Out of adjusting mode

How to adjust the flow time in Touch B and Touch E
1) Open the piezo cap using the provided 2 mm
Allen key.
2) Disconnect the power supply (batteries or
transformer).
3) While the power source is disconnected,
verify that the solenoid valve is installed and
touch the piezo cap twice.
4) Then, reconnect the power supply.
5) The indicator light (LED) on the back of the
Piezo cap will start blinking. After a few blinks
the LED will give a steady red light. Touch the
Piezo cap when the steady red light is still on to
enter into the adjusting mode. When done correctly, the light will stop blinking.
Note: If you will not press at the indicated area, the previous adjustment will
remain.
The following examples show how to manage the adjustment levels:
Example 1: You wish to adjust the flow time to 20 seconds.
At level 1 perform 3 steps of 1 second (you will get 3 seconds). Total: 3 seconds
Go to level 2 and perform 1 step of 2 seconds (you will get 2 seconds). Total: 5
seconds)
Go to level 3 and perform 1 step of 15 seconds (you will get 15 seconds). Total: 20
seconds.
Example 2: You wish to adjust the flow time to 45 seconds.
At level 1 perform 1 step of 1 second (you will get 1 second). Total: 1 second
Go to level 2 and perform 7 steps of 2 seconds (you will get 14 seconds). Total: 15
seconds)
Go to level 3 and perform 2 steps of 15 seconds (you will get 30 seconds). Total: 45
seconds.
Example 3: You wish to adjust the flow time to 60 seconds.
At level 1 perform 10 steps of 1 second (you will get 10 seconds). Total: 10 seconds
Go to level 2 and perform 10 steps of 2 seconds (you will get 20 seconds). Total: 30
seconds)
Go to level 3 and perform 2 steps of 15 seconds (you will get 30 seconds). Total: 60
seconds.

6) By touching the Piezo cap the new flow time will be programmed. In adjusting
mode level 1, each touch increases the flow time by 1 second with a maximum of 10
seconds. You will see the LED blinking every time that a new step is performed.
7) If your desired flow time is within 10 seconds, no other adjusting levels are
needed and you can
stop pressing the Piezo
cap. The LED will blink
2 times, then 3 times
and after 4 times you
will leave the adjusting
mode. The Touch is now
adjusted to the desired
flow time.
8) If you need to perform
steps at adjusting level
2, wait after you see the
LED blink twice and then,
perform the needed
quantity of steps (with a
maximum of 10 steps of
2 seconds).
If you do not need more
levels, stop pressing.
The indicator light will
blink 3 times and after 4
times you will leave the adjusting mode. The Touch is now adjusted to the desired
flow time.
9) If you need to perform steps at adjusting level 3, wait after you see the LED blink
3 times and then, perform the needed quantity of steps (with a maximum of 2 steps
of 15 seconds).
10) To leave the adjusting mode wait until the LED blinks 4 times. The Touch is
adjusted to the desired flow time.

lOW BaTTERY INDIcaTOR
The Touch faucet has an advanced battery level management system
consisting of two steps:
Step 1
The battery still has enough power to open and close the solenoid valve.
At this first step the battery level management system allows the solenoid
valve to open and close but will activate a warning indicator light.
The LED at the back of the Touch cap will blink twice when the battery
level management system has activated step 1 and the user touches the
designated area.
Step 2
At his point the battery might not have enough power to open and close
the solenoid valve.
The battery level management system does not allow the solenoid valve
to open. Instead of providing an opening and closing pulse, the system
provides two closing pulses.
The LED at the back of the Touch cap will blink three times when the
battery level management system has activated step 2 and the user
touches the designated area. Water will not flow since the solenoid will
not be opened.

BaTTERY REPlacEMENT
1. Carefully open the battery box.
2. Remove the old battery.
3. Replace the used battery with a new 9V battery. A Lithium battery is
recommended.
Note: Do not allow moisture or water
into the system
4. Close the box.
5. In order to avoid entering into the
adjusting mode, wait 10 seconds
before operating the system.
MAINTENANCE
Filter cleaning instructions
The Touch is provided with one stainless steel filter preventing foreign particles to
enter the lines. If the water flow has decreased, this may be because the filter is
clogged. The filter can be cleaned as follows:
1. Shut-off the water shut off valve.
2. Disconnect the water supply inlet from the adapter at the solenoid valve
housing.
3. Remove the filter from the adapter and wash it under running water.
4. Reassemble the parts.
5. Reconnect the solenoid valve housing and restore the incoming water
supply.
6. 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 us 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.
Important: Spent batteries should not be disposed of with
normal household waste. Contact your local authority for
information on waste disposal and recycling.
