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 Alcala 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.
HOW TO ADJUST THE FLOW TIME IN ALCALA
1) Open the piezo cap using the provided 2 mm Allen key.
2) Disconnect the internal battery.
3) Touch the piezo cap twice.
4) Then, reconnect the battery.
5) The indicator light (LED) on the back of the Piezo cap will start blinking. Aer 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.
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 maxi-
mum 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 aer 4
times you will leave the adjusting mode.
The Foot Washfrees now adjusted to the desired flow time.
8) If you need to perform steps at adjusting level 2, wait until you see
the LED blink twice and then, perform the needed quantity of steps (with a maximum of 
steps of  seconds).
If you do not need more levels, stop pressing. The indicator light will blink
3 times and aer 4 times you will leave the adjusting mode. The Alcala is now adjusted to
the desired flow time.
9) If you need to perform steps at adjusting level 3, wait until 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 Foot Washfrees now adjusted to the desired flow time.

FILTER CLEANING INSTRUCTIONS
The system is provided with two stainless steel lters preventing foreign particles to enter
the lines. If the water flow has decreased, this may be because the lters are clogged. The
lters can be cleaned as follows:
1. Shut-o the water shut o valve.
2. Disassemble the Alcala, and remove the lter located between the body and the shut
o valve.
3. Wash the lter under running water.
4. Reassemble the parts.
5. 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 dam-
age the surface of the faucet.
For surface cleaning of faucets use 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.

LOW BATTERY INDICATOR
Alcala has an advanced battery level management system consisting of two steps. In the rst step,
the battery still has enough power to open and close the solenoid valve and allows the solenoid
valve to open.
In the second step the battery might not have enough power to open and close the solenoid valve.
In this case, the battery level management system does not allow the solenoid valve to open.
Instead of providing an opening and closing pulse, the systems provides two closing pulses.

1
Unscrew the M4X4 Allen screw
on the Alcala cap and pull out the
piezo cap.
2Disconnect the connectors and take
out the old battery.
3
Replace the used battery with a
new 9V battery. A lithium battery is
recommended.
4Reconnect the connectors between
the battery and Piezo cap.
5Place the Piezo cap back into place
and tighten the Allen screw.
NOTE:
· Do not allow moisture or water into the system while the battery is being replaced.
· The interior of the shower control must be fully dry before reassembling the parts. If it is not fully
dry, carefully dry it.
