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

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
