1.1 Using the quick release fastener
1 Installation (water inlet connector and device configuration)
It is highly recommended for a specialist to carry out the connection to a water supply.
We recommend you to contact the plumber of your choice.
The connection parts of the ECAIA ionizer S have quick release fasteners to simplify the installa-
tion of the water pipes. The procedure below describes how these quick release fasteners op-
erate.
Always make sure that the tap water supply hose (A-6) is not
bent or damaged in any way at the point of insertion into the
quick release fastener opening. If this is the case, cut off the
damaged piece.
The tap water supply hose (A-6) must be inserted at least 1 cm
into the quick release opening.
Attach the safety clip (A-11).
To disconnect the hose from the quick release fastener, the tap
water supply hose (A-6) must not be under pressure. Remove
the safety clip (A-11), push the safety ring all the way back
and then pull the tap water supply hose (A-6) out of the quick
release opening.

1.2 Sieve for tap water supply hose
1.3 Temporary connection to the water tap
1. Remove the aerator from the faucet and replace
it with the diverter valve (A-9). The intermediate
thread is used depending on the type of a thread
(internal or external thread).
2. Connect the tap water supply hose (A-6) to the
quick release fastener opening on the diverter
valve (A-9) and fix the safety clip 1/4" (A-11).
Faucet
A small sieve (A-7) is included with a device, which prevents coarse particles in the tap water
from entering the device.
To mount the sieve (A-7), simply cut the tap water supply hose (A-6) in half and connect the
two ends to the quick release fastener opening on the sieve (A-7). Please pay attention to the
direction of the flow (arrow shown on the sieve); the arrow must point in the direction of the
water flow. Finally, firmly secure the 2 safety clips 1/4" (A-11).
The ideal position for the sieve is immediately following the diverter valve (A-9) or the T-piece
(A-10).
Note: If the water flow becomes slower, check the sieve (A-7) and clean it. If it is very dirty, it
must be replaced.
The ECAIA ionizer S can be connected to any water tap using the diverter valve (A-9), provid-
ed that the water tap has a compatible standard thread (internal thread M24, external thread
M22).

1110
1.4
Permanent connection to the angle valve
(appliance in above-counter
position)
1. Install the T-piece (A-10) on the angle valve of the cold
water pipe. If necessary, the cold water supply pipe to
the faucet must be disconnected and connected with the
T-piece in between.
CAUTION: When assembling please make sure the connection pins on the T-piece
do not bend sideways. This may cause a micro crack, which can even lead to break-
age due to the constant water pressure.
The ECAIA ionizer S can also be attached to the angle valve (3/8") under the sink. If the device
is placed above the working surface, the tap water supply hose (A-6) must go through a hole
made in the working surface or sink with a diameter of at least 6 mm.
3. Connect the other end of the tap water supply hose (A-6) to the quick release fas-
tener opening of the water inlet (B-11) on the bottom of the ECAIA ionizer S and fix
the safety clip 1/4" (A-11).
4. The water pressure can be adjusted with the
water flow rate regulator (B-3) on the device.
Note: The ECAIA ionizer S is only suitable for cold drinking water! The flow of warm or
hot water into the device can damage the filters and various seals.
IMPORTANT: If electric water heater is installed to depressurize through the faucet, the
connection should not be carried out using an adapter. This may cause damage to the
water heater.

2. Connect the tap water sup-
ply hose (A-6) to the quick
release fastener opening on
the T-piece (A-10) and fix the
safety clip 1/4" (A-11).
3. Pass the tap water supply
hose (A-6) through an open-
ing in the counter or sink
(diameter at least 6mm) to
the position where you have
placed the ECAIA ionizer S.
4. Connect the other end of the
tap water supply hose (A-6)
to the quick release fastener
opening of the water inlet
(B-11) on the bottom of the
ECAIA ionizer S and fix the
safety clip 1/4 "(A-11).
5. The water pressure can be
adjusted with the adjustment
screw on the T-piece (A-10).

1.5 Permanent connection to the angle valve (ECAIA ionizer S+;
appliance in below-counter position; using the additional ECAIA
ionizer S faucet)
The ECAIA ionizer S+ can be permanently con-
nected to the angle valve under the sink, as de-
scribed under point “1.4 - Permanent connection
to the angle valve (appliance in above-counter
position)”. Due to the positioning of the device
under the sink, it must be operated using the
special ECAIA ionizer S faucet. A solenoid valve
must also be interconnected to control the water
supply.
To install the ECAIA ionizer S faucet, use the user
manual included with the faucet.
Note: A solenoid valve is to be used, if the
ECAIA ionizer S is reprogrammed to ECAIA ion-
izer S+. Therefore, it is not possible to receive
filtered water in the event of a power shortage.
1.6 ECAIA ionizer S wall mounting
The ECAIA ionizer S can be placed standing or mounted to the wall. Wall mounting is very easy
and the ECAIA ionizer S can thus be positioned in any kitchen, next to or behind the sink, to
save space.
1. Attach the supplied installation diagram
(A-12) to the wall where you want to posi-
tion the device.
2. Choose the vertical or horizontal mounting
method and drill 2 holes accordingly.
3. Insert the supplied dowels (A-12) and se-
cure the screws (A-12) into the wall.
4. Hang the ECAIA ionizer S on the screws
you just attached.

13
For reasons of hygiene, it is recommended to use the supplied acidic water tap (A-3) with the
ECAIA ionizer S (not necessary with the ECAIA ionizer S+).
1. Screw the alkaline outlet hose (A-2) to the
upper water outlet (B-5).
2. Plastic hose for acidic water 7/9 mm (A-
4) should be attached to the lower water
outlet (B-12) of the device. If necessary,
the tube can be secured with the sup-
plied tube clamp (A-5). Since no water
pressure is exerted on this tube, this step
is optional.
3. Using the attached double-sided adhesive tape, secure the magnetic button of the
acidic water tap (A-3) to the working surface or to the sink so that the stainless steel
spout from the acidic water tap (A-3) opens into the sink. Afterwards cut the plastic
hose for acidic water 7/9 mm (A-4) to the required length and attach the end to the
acidic water tap (A-3). The plastic hose for acidic water 7/9 mm (A-4) should not be
higher than the position of the water flow rate regulator (B-3). Too long, bent or posi-
tioned higher tube may affect the ionization or the taste of the water.
1.7 Assembly of the alkaline outlet hose and the acidic water tap
Note: Make sure that the alkaline outlet hose (A-2) or the stainless steel spout from the
acidic water tap (A-3) do not come into contact with dirty objects. Likewise, the plastic
hose for acidic water 7/9 mm (A-4) should not be connected directly to the drain. This
could cause re-contamination of the device.

1.9 Language settings
1.8 Before use
The ECAIA ionizer S has a guide speech which informs the user about different settings. You
can choose between 4 different languages. English (LA0 default), German (LA1), Italian (LA2),
or Spanish (LA3).
Before you can use the ECAIA ionizer S, you must carry out the following steps:
1. Plug the power cable of the ECAIA Ionizer S into the socket. The device requires 230V (US
model 120V).
2. Turn on the water and wait until the filters and the device are full. The device switches on
automatically as soon as water flows through the device.
Note: The ECAIA ionizer S is only suitable for cold drinking water!
When the filters are new, the water may initially come out dark due to the activated carbon par-
ticles. Let the water run until it clears out. If necessary, switch the device on and off several times
so that all suspended solids are rinsed out.
If you want to change the language, proceed as follows:
1. With the device switched off, press the ”PURIFY” button and hold it down for at least
3 seconds. The display switches on and ”LA0” appears.
2. You can select the desired language by pressing the ”PURIFY” button again:
LA0 = English
LA1 = German
LA2 = Italian
LA3 = Spanish
3. After you have selected the language, wait at least 3 seconds until the display
switches off again and the selected language is automatically saved.

1.10 Volume configuration
There are 2 ways to adjust the volume.
Either via the volume control (B-10) or via the submenu.
Note: Unfortunately, only setting option B is available for the models of the first production
series.
A Configuration via the volume control
Using a small Phillips head screwdriver, you can turn the small volume control screw (B-10)
on the back of the device and thus adjust the volume of the guide speech.
B Configuration via the submenu
The volume can be adjusted in 3 levels via the submenu or switched off completely.
To configure via the submenu, proceed as follows:
1. Switch off the device and simultaneously press buttons of
alkaline levels 1 and 2 denoted ”ALKALINE” and hold them
down for at least 3 seconds. Afterwards the display turns
on.
2. Press button of alkaline level 1 denoted ”ALKALINE” until ”U.3 9d” appears on the display.
3. By pressing button acidic level 1 denoted ”ACIDIC” you can select the desired volume:
U3 = loud
U2 = medium
U1 = quiet
U0 = mute
4. When you have selected the desired volume, press buttons
of alkaline level 1 and 2 denoted ”ALKALINE” again at the same
time and hold them until the display switches off. This saves the
setting.
Note: Please make sure you do not make any other adjustments in the submenu. There is a
risk of changing other parameters and thus impairing the function of the device!

1716
1.11 Flow rate configuration
Depending on how the device was connected, there are 2 dif-
ferent ways to regulate the water pressure and thus the flow
rate. The water pressure should always remain unchanged to
guarantee a constant ionization performance. The general rule
is: The slower the flow rate, the stronger the ionization perfor-
mance.
Note: If the water pressure is too high, the message “Error 4” or “Error F” appears on
the display (B-22). If the water pressure is too low, the device switches off automatically.
• Connection to the faucet according to description 1.3:
If the device is connected to the water tap using the diverter valve (A-9), the water
flow rate regulator (B-3) on the device is used to adjust the water pressure. Com-
pletely open the cold water faucet and position the switch-over lever of the diverter
valve (A-9) so that the water flows into the ECAIA ionizer S. Afterwards turn the water
flow rate regulator (B-3) on the device slowly clockwise towards OFF until the bars
on the flow rate display (B-21) are in the “normal” range. Once the flow is set, you
can turn the device on or off simply by turning on or off the water tap. If the water
supply is interrupted, the device switches off automatically.
• Connection to the angle valve according to description 1.4 and 1.5:
If the device is connected directly to the angle valve using the T-piece (A-10), the
pressure can be regulated at the T-piece (A-10). Turn the water flow rate regulator
(B-3) on the device counter-clockwise towards ON until it stops. Thereafter regulate
the water pressure on the T-piece (A-10) by opening or closing the small screw on
the opposite side of the quick release opening until the bars on the flow rate display
(B-21) are in the “normal” range. The device can be switched on or off by turning the
water flow rate regulator (B-3) on the device. If the water supply is interrupted, the
device switches off automatically.

17
1.12 Description of the buttons
The ECAIA ionizer S has a total of 8 buttons to produce water with different properties.
These framed
buttons have a
memory function.
So if you select one
of these ionization
level buttons and
then switch off the
device, this setting
remains saved.
1. Alkaline water (B-24), but-
tons of alkaline levels 1 to 5
(ALKALINE) - alkaline water
flows out of the upper water
outlet (B-5), 1 = slightly alka-
line, 5 = strongly alkaline.
2. Acidic water (B-25), but-
tons of acidic levels 1 to 2
(ACID) - acidic water flows
out of the upper water outlet
(B-5), 1 = slightly acidic, 2 =
strongly acidic.
3. Filtered water (B-26), button
of the level PURIFY - filtered
water flows out of the upper
water outlet (B-5) and lower
water outlet (B-12), ioniza-
tion is deactivated.
Note: Since the selection of the alkaline levels 1 to 5 (B-24) produces alkaline water
at the upper water outlet (B-5) and acidic water at the lower water outlet (B-12) or
at the acidic water tap (A-3), the buttons for acidic water (B-25) are generally rarely
used.
Example: You select the alkaline level 3 and then switch off the device. The next time you
switch on the device, alkaline level 3 is automatically selected again.

1918
1.13 Control of the ionization performance
The ionization performance depends on the water used and can therefore vary greatly from
place to place. It is therefore very important to control the ionization performance.
Tip: Check the ionization performance regularly, as changing the filter or calcification of the
electrolysis chamber can also affect the ionization performance. If the device is new or new fil-
ters have been installed, the measurement should be carried out again after 2-3 days, as new
filters can influence the measured values.
You can control the ionization performance by measuring the pH value. Use the pH testing liq-
uid provided with the pH level color chart (A-8).
Important: Changing the flow rate also changes the
ionization performance. Please make sure that the flow
rate always remains the same, i.e. that the same num-
ber of bars always light up on the flow rate display (B-
21) to indicate the “normal” range. The general rule
is: The slower the flow rate, the stronger the ionization
performance.
The ECAIA ionizer S has 5 levels of alkaline water (B-
24), 2 levels of acidic water (B-25) and one level of
filtered water (B-26). Please check the ionization per-
formance using the 5 alkaline levels (B-24).
To measure the ionization performance, switch on the device and select the alkaline level 1.
Let the water run for about 30 seconds, then take a water sample and add a few drops of pH
testing liquid (A-8). Depending on the water color, you can use the pH level color chart (A-8) to
identify the corresponding pH value for this level. Then select the alkaline level 2, let the water
run for about 30 seconds and repeat the pH value measurement. Continue these measure-
ments up to alkaline level 5. Ideally, the water should turn purple in the area of alkaline levels 3
or 4 (pH 9 to 9.5).
These framed buttons have
NO memory function. If you
selected one of these buttons
when switching off the de-
vice, the next time you start
the device, the last selected
level, which has a memory
function, will be selected.
Example: When you switch on the device the alkaline level 4 is set. Select the alkaline level 5
and switch off the device. The next time the device is switched on, the alkaline level 4 is auto-
matically selected again as the alkaline level 5 can not be saved.

19
Tip: The less the amount of test water is, the less pH testing liquid you need. 5 to 10 milliliters
of test water are sufficient to determine the pH value. Only 1-2 drops of pH testing liquid is re-
quired for this.
Warning label for pH testing liquid (A-8):
• Do not drink the pH testing liquid. If the pH testing liquid is accidentally consumed,
immediately drink plenty of water.
• Avoid eye contact. If the pH testing liquid comes into contact with the eyes, wash them
out immediately with plenty of water and consult a doctor.
• Do not store pH testing liquid near fire or a source of heat.
• Keep pH testing liquid out of the reach of children.
• Store pH testing liquid in a cool, dark place. Avoid high temperatures and excess hu-
midity.
• Cap the vial after each use. Do not spill any pH testing liquid; resulting stains are
difficult to remove. If the pH testing liquid gets on surfaces, wipe up immediately with
plenty of water.
1.14 Setting ionization performance
The ECAIA ionizer S has a total of 28 alkaline and acidic levels, which can be controlled by con-
figuring the ionization performance via the submenu.
The respective 5 alkaline and 2 acidic levels can be set to low or high level again using 4 levels
in the submenu. The device is configured to submenu level 3 at the factory.
If a purple color (pH 9 to 9.5) after a period of use of 2-3 days with the alkaline levels 3 or 4 is
not achieved, the ionization performance can be set higher. If, on the other hand, a purple color
(pH 9 to 9.5) is already in the alkaline level 1 or 2, the ionization performance can be set lower.
How to set the ionization performance:
1. Turn on the device so that water flows out.
2. Select the alkaline level 1 and hold this button down
for at least 5 seconds until the display switches over.
You will read “13” on the display. The first number
(1) stands for the respective level (in
this case for “alkaline level 1”), the
second number (3) stands for the
ionization performance in the sub-
menu. You can choose between 1
and 4, where 1 corresponds to the
lowest and 4 to the highest ioniza-
tion performance.

2120
3. By pressing the “alkaline level 1” button again, you
can switch through the individual levels of ioniza-
tion performance. If you want to set the ionization
performance to a higher level,
press the “alkaline level 1” button
until “14” appears on the display.
If you want to set the ionization
performance to a lower level, “11”
or “12” should appear on the
display.
4. Save the setting by pressing the “PURIFY” button.
The display will show the alkaline level 1 again.
5. Repeat the settings from points
1 to 4 for all other levels (alka-
line level 2 to 5 (B-24) and acidic
level 1 to 2 (B-25)).
Important: Make sure that the same ionization performance is set in the submenu for each lev-
el (alkaline level 1 to 5 and acidic level 1 to 2). For instance, if you have set the ionization perfor-
mance to 4 for “alkaline level 1” (display submenu = 14), then all other levels must also be set
to ionization performance 4.
Example: • alkaline 1 = 14
• alkaline 2 = 24
• alkaline 3 = 34
• alkaline 4 = 44
• alkaline 5 = 54
The ionization performance can also
be regulated by changing the flow
rate. The faster the flow rate, the less
ionized is the water. If the bars on the
display (B-21) are in the lower “normal”
range, the flow rate is slower and thus
the ionization performance is stronger
than when the bars are in the upper
“normal” range, with the water flowing faster through the electrolysis unit.
Depending on the water quality, it is possible that a pH value of 9 (purple coloring) can only be
achieved with setting the alkaline level to 5, with very slow flow rate (bars in the lower “normal”
range) and with the highest ionization performance (display submenu = 54).
Note: Make sure that water always comes out of the lower water outlet (B-12) (acidic water tap
(A-3)). Otherwise, proper ionization cannot be guaranteed.
• acidic 1 = 64
• acidic 2 = 74
