3. Description
3.1. The principles of electrolysis
Salt water electrolysis separates salt (NaCl) into sodium (Na) and Chlorine (Cl). The chlorine is im-
mediately dissolved in the water to produce hypochlorous acid (HClO). This powerful disinfectant
destroys bacteria and algae before turning back into salt.
The quantity of chlorine needed to disinfect a swimming pool increases with the water temperature
and pH.
Chlorine production must be adjusted to the environment and water characteristics:
• water conductivity
www.c-
cei.fr 3

Technicalinst. guide Limpido XC2 v4.0
• water temperature
• the volume of the pool to be treated
• water pH
For the installation’s safety, the Limpido XC2puissance only produces chlorine
when the flow meter indicates that water is actually flowing through the cell.
During these filtering periods, the chlorine production time is composed of two-period cycles (Nor-
mal and Reverse) that alternate electrode polarity. This polarity reversal makes it possible to prevent
the electrodes from scaling.
Thus, the production cycle is split into 4 phases:
1. Phase 1, normal production (positive)
2. Phase 2, standby
3. Phase 3, reverse mode production (negative)
4. Phase 4, standby
At the end of the filtering period, the Limpido XC2 stops producing and restarts it exactly where
it left off when filtering restarts.
The main benefit of this choice of operating mode is to always guarantee (even if there is a power
failure) that normal and reverse production times are strictly identical and, as a result, guarantee the
best cell descaling possible (giving quality production and long equipment service life).
3.2. Presentation of the Limpido XC2
Effective and optimised production - depending on water temperature - reduced when the automatic
cover is closed - A selection of several production modes
Single block compact and strong cell - fitted with solid titanium plates.
Self cleaning cell using reversed polarity.
Increased safety using flow detection.
Installs in just a few minutes, easy connection.
3.3. Production heat regulation (AUTO mode)
As the water temperature varies during the season, production times must be adjusted. This temper-
ature regulated production is carried out automatically by the Limpido XC2 in AUTO production
mode.
www.c-
cei.fr 4

Technicalinst. guide Limpido XC2 v4.0
The calculated production time is (in hours): (Pool temperature - Minimum temperature*) + 1.
*The minimum temperature (15°C by default), can be configured. The calculated production time
can therefore be influenced.
There will be no production below this minimum temperature.

However, it is not recommended to lower the minimum temperature below 12°C in order to protect
the electrolysis cell plates from low temperature operation, as this would reduce their service life.
If production time seems insufficient, make sure the pool volume is set to the maximum in order
to optimise chlorine production (see 6.3.4), then, if necessary, use the ON mode (24h/24h) or the
PROG mode (by entering the required number of hours in "Prog hours". (see 6.3.5)

4. Installation
4.1. Hydraulic installation
The different elements to fit to the pool piping are: the electrolysis cell (C), the flow detector (B)
(installed upstream of the cell but on the same section of piping) and the earthing device (D).
The cell (C), which is the essential part of the Limpido XC2, must be handled with care. It is fitted
with solid titanium electrode plates treated with ruthenium oxide and is specially designed for a
maximum service life and to limit maintenance operations. The temperature sensor is built into the
cell and uses the same connector.
The Limpido XC2 cell should be installed on 50mm diameter piping, using the supplied union
connectors. It should be installed downstream of the filtering system (after the filter) and can be
placed either horizontally or vertically.
Prefer using a by-pass (mandatory in excess of 22m3/hour) so that the flow through the cell can be
controlled without stopping filtering.
4.1.1. Bypass installation
The flow detector must be placed either just before or just after the cell on the
same branch: there must not be any derivation, valve or anything else between
the two!

cei.fr 6

Technicalinst. guide Limpido XC2 v4.0
4.1.2. Water flow detector
The Limpido XC2 is shipped with a flow detector. The flow detector is built into the cell delivered
with the Limpido XC2.It prevents the electrolysis unit from running when there is no flow, or during
a backwash. It is used to prevent all risks of hydrogen accumulating or excess heating and thereby
makes the system safer.
1. Install the fixing collar on the piping after having previously drilled it.
2. Screw the male / male ¾" nipple into the fixing collar. (use Teflon tape to make sure it is
watertight)
3. Screw on the flow detector (use Teflon tape to make sure it is watertight). Do not over-tighten
the detector.
Takespecialcareoverthewaterflowdirectionsothatthedevice
correctly detects the flow. For the flow detector to be correctly
positioned, the arrow engraved on it must point in the direction
the water flows.
4.1.3. Earth electrode
ThePool-Terredeviceshipped withthe LimpidoXC2 isused todrain thewater's electrostaticcharge
to the earth. When this system is connected to a "proper earth" (the connection must be direct to a
local earth electrode), it eliminates leakage current and limits the reduction-oxidation phenomena
that cause corrosion.
1. Install the fixing collar on the discharge piping after having drilled it, downstream from the
heating or electrolysis devices.
2. Screw the electrode into the fixing collar. (use Teflon tape to make sure it is watertight)
3. Connect the Pool-Terre directly to the earth electrode using a correctly sized green and yellow
wire. (minimum 4mm²)

4.2. Connection to electricity
Installation of this project involves a hazard of electric shocks. We strongly
recommend you contract a professional installer. Incorrect installation places
you in danger and may irreversibly damage the product and the equipment
connected to it.
For safety reasons and in compliance with the NF C15-100 standards, the
Limpido XC2 box must be installed
• either at 3.50 m from the pool edge. This distance takes into account the dis-
tance around obstacles. If the Limpido XC2 box is installed behind a wall,
the distance will include the length of the path taken to move around the wall
to reach the box.
• or in an in-ground space immediately next to the swimming pool. In this case
the space must be accessible via a hatch which requires a tool to open it.
The Limpido XC2 power supply box
• must not be directly installed outdoors, it must be sheltered from rain, cleaning or watering spray,
and UVs (sunlight).
• is spray resistant but must not be installed in a floodable area.
• must be fitted on a level and stable support and fixed to the wall using the supplied anchors and
screws.
To keep it watertight, it is essential to check that the seal is correctly positioned when closing the
cover, and to tighten the 2 screws on the front face every time the box is accessed.

4.2.1. Power supply, cell, flow detector
The box is shipped with a power supply cable that can be connected to the mains in the technical
room using a standard plug and socket (230V / 50 Hz). This socket must be protected by a 30mA
ground fault circuit breaker in compliance with the NF C15-100 standard.
The box uses a flow detector to know whether the filtering system is running or
not.THE CONTROL BOX MUSTNEVER BE CONNECTED TOA SOCKET
COUPLED TO THE FILTERING SYSTEM!

cei.fr 9

Technicalinst. guide Limpido XC2 v4.0
4.2.2. Cover contact
For pools with an automatic cover, the quantity of chlorine produced must be lowered when the
pool is covered. Indeed, in this situation the water is sheltered from UVs and most pollutants, so
the amount of chlorine required is significantly less. Most covers are fitted with a travel switch to
which the Limpido XC2 can be connected to adjust its production.
This contact must be open when the cover is open, and closed when the cover is over the pool.
Use the cable passage at the back of the control box and connect the two contact wires directly to
the module (see photo below).
*The cover contact must imperatively be a dry contact with no electric poten-
tial. No other wires (coupling for other devices, etc.) must be connected at the
samelocation. A connectionerror can seriouslydamage the device and will void
the guarantee.
4.2.3. Cell connection
Connect the cell to the side connector and lock it in place using the metal staple supplied with the
accessories.

5. Start up
The device settings can only be adapted through regular analysis.
Following the steps described below carefully makes it possible to start up with-
out experiencing any issues.
The chemicals used in pools are highly corrosive and can have a harmful effect
on health and the environment.
These products must be handled with care and stored in a suitable location.
5.1. Stabiliser
At room temperature chlorine is a gas. Its solid form (tabs, pellets, etc.) is obtained by combination
with a molecule of cyanuric acid. This cyanuric acid is a stabiliser because it protects the chlorine
from breaking down under the action of ultraviolets (UVs) from the sun. On the other hand, the
cyanuric acid is not used and inevitably accumulates in pools treated using chlorine tabs and ends up
by inhibiting the chlorine's potential. For swimming pools, the maximum recommended cyanuric
acid concentration is 80 ppm (or mg/l).
Salt electrolysis treatments avoid this excess cyanuric acid. The use of pool salt
is recommended as it is pre-dosed with stabiliser.
5.2. Salt level check
The Limpido XC2 is designed to run in water with conductivity corresponding to a salt level of
between 2.5g/l and 5g/l at 25°C.
To accurately check your pool water's salt level, we recommend using a conductivity meter. This
easy-to-use instrument gives a direct salt level reading in g/l. Analysis strips are also available to
effectively check your water's salt level.
When the salt level is not appropriate, the Limpido XC2 stops production if the salt level is too high
or too low. If one of these faults occurs, first check that the cell is properly connected to the control
box and that it is in working condition. Then make the required corrections to the pool water.
Water's conductivity is proportional to its salinity, but also depends on the temperature for 2.2%
per degree Celsius.
Salinity (in g/l) 10°C 15°C 20°C 25°C 30°C 35°C 40°C
Min 3.3 3.1 2.8 2.5 2.2 2.0 1.7
Ideal 4.7 4.3 3.9 3.5 3.1 2.7 2.3
Max 6.7 6.1 5.6 5 4.5 3.9 3.4
www.c-
cei.fr 11

Technicalinst. guide Limpido XC2 v4.0
At 35°C the maximum salt level is therefore changed from 5g/l to 3.9g/l.
5.3. TAS / TH check
It is recommended when installing to ask a specialist to test the pool water's TAS (Total Alkaline
strength) and/or TH (Total Hardness). These two measurements are usually quite close and are most
often expressed in French degrees (°F). If the TAS and TH are different, use the mean value of the
two measurements. It is important to highlight that very soft water (TH <10°F) has the advantage
of preventing scale deposits, but can also be aggressive, depending on the pH and TAS.
At the other end of the scale, very hard water (TH>35°F) will cause scale deposits on the installation.
It is therefore recommended to correct the TAS and TH using the appropriate chemicals. Contact
your pool builder for more details.
5.4. pH checks
pH, or potential Hydrogen, measures the acidity of the water. Its value is between 0 and 14. A
solution with a pH of 7 is neutral. If the pH is below 7 the solution is acid, and if it is above 7 it is
basic (or alkaline). For the comfort of bathers, effective treatment and reliability of the installation,
the swimming pool water's pH must be kept at about 7.2. However, as the ideal pH for a pool
depends on all the elements used (coating, materials, etc.) in the pool, please check the pool builder's
recommendations. When the pH goes up from 7.2 to 8.2, the percentage of active chlorine passes
from 70% to 20%.
For more effective treatment it is essential to keep the water's pH within the range of ideal values
defined by your pool builder (see manuals).

6.3.5. ELECTROLYSIS MENU
This menu gives access to the production settings.
Screen Function
Prod. mode AUTO Used to selected the production mode (see below).
TH = 15°f
Used to enter the TAS/TH value (configurable from 10 to
50°f) to adapt the polarity reversal time to the water alkalinity
and hardness. To protect the electrolysis cell service life, too
frequent polarity reversals should be avoided. It is therefore
advisable to adapt polarity reversal frequency to actual needs.
The TAS (Total Alkaline Strength) and the TH (Total Hard-
ness) are values that give an idea of water hardness and the
risks of scale deposits in the cell. Polarity reversal frequency
will be calculated using this value. The value is characteristic
of the water's geological origin and does not vary much. It
only needs to be measured when the device is started for the
first time, or after a change of water. It is measured using the
strips from the analysis kit. The value read on the strip must
be entered into the device.
Mini temp. = 15°C
Used to enter the minimum temperature from which the elec-
trolysis device will start producing in PROG and AUTO
mode. Below this temperature, in both operating modes the
device will not produce chlorine (configurable from 5 to
25°C).
SHOCK run = 20h
Used to configure the duration of a "SHOCK" production cy-
cle. Once this time period is over, the device automatically
returns to AUTO mode (configurable from 8 to 24 hours).
Cover run = 2h Used to set the cycle time when the pool cover is closed (con-
figurable from 1 to 12 hours).
Prog. hours =8h
Used to set the production time (configurable from 1 to 24
hours): This setting defines production time in PROG mode
(in AUTO mode the time is calculated by the device).
The different production modes are the following:
• OFF: Chlorine production is disabled.
• ON: Chlorine production is permanent whenever a flow is detected. the SHOCK function is rec-
ommended rather than the ON function when a shock treatment is needed (in SHOCK mode,
once the programmed time is over, the device automatically switches to AUTO mode). Closing
the cover has no effect on this mode.
• PROG: Chlorine production will occur every day for the number of hours programmed in the
"Prog. hours" menu. If the cover is closed, the number of hours of production will be the number
entered on the "Cover cycle" menu
www.c-
cei.fr 19

Technicalinst. guide Limpido XC2 v4.0
• AUTO: Chlorine production will automatically occur every day for a number of hours calculated
depending on the water temperature and the pool volume entered on the Pool vol." menu. (see
6.3.4) Remember, the calculated production time is (in hours): (Pool temperature - Minimum
temperature*) + 1. (see 3.3) If the cover is closed, this time is divided by 4.
• SHOCK: Chlorine production will occur on the first day for the number of hours programmed on
the "SHOCK hours" menu. Once this time has expired, the device automatically returns to AUTO
mode. This mode is used to remedy water that is starting to turn green or water that is no longer
clear. Closing the cover has no effect on this mode.

6.4. Low temperature
The need for disinfectant drops significantly when the water temperature drops. In order to avoid
using the electrolysis cell needlessly, the device stops producing when the water temperature is
lower than the temperature programmed on the "Min. temp." menu and displays, on the system
status screen (screen saver);
This automatic wintering mode is only enabled in PROG and AUTO mode. This setting is not
taken into account in SHOCK or ON mode.
6.5. Automatic cover
If the Limpido XC2 is connected to an automatic cover, it detects when the cover is closed. If the
cover is closed,
• In PROG mode, production time is the time set on the "Cover cycle" menu.
• In AUTO mode, the calculated production time is divided by 4.
When the control box detects that the pool cover is closed it displays on the system status screen
(screen saver);
