2.1 Preparing the pool: water balance
These appliances are designed to disinfect pool water using the salt water chlorina on func on.
It is essen al that the water balance and salinity (4 g/L) are checked and adjusted before installing the appliance. Making
sure that the water balance and salinity are correct from the very start will reduce the likelihood of encountering problems
on the  rst days of opera on or during the season the pool is in use.
Even though it is an autonomous system, it is essen al to regularly analyse the water to check the water
balance parameters and adjust them if necessary.

2.2 Installing the control box
• The control box must be installed in a dry ven lated technical room protected against frost, with no pool maintenance
products stored nearby.
• The control box must be installed at a distance of at least 2.0 m from the outside edge of the pool. Any addi onal local
legisla on in force concerning the installa on of the control box in the country concerned must be complied with.
• It must not be installed more than 1.5 metres from the cell (maximum cable length).
• If the box is  xed to a post, a water ght panel must be  xed behind the control box (350x400 mm minimum).
• Fix the support solidly to the wall or the water ght panel, and place the control box on it using the screws provided.

2.3 Installing the cell
• The cell must be installed on the piping a er the  ltra on system ( ), a er any measurement sensors, and a er any
hea ng systems. Ei² - GenSalt OE Ei² Expert
• The cell must be installed on a horizontal pipe so as to guarantee that the water fl ow passing therethrough is primarily
horizontal, and that the angle/slope does not exceed 30°. The pipe must have a free horizontal length of at least 30 cm,
on which the cell will be installed. The cell must also be installed as far as possible from any right angle or curve formed
in the piping ( ).
• Respect the water fl ow direc on (see arrows ( )).

• Dismantle the cell ( ).
• Posi on the EU pipe adapter (DN 50 mm) upside down at the posi on where the pipe ( ) will be installed.
• Use a drill bit or centre-punch to mark the posi ons of the holes to be drilled on the pipe, remove the EU pipe adapter
(DN 50 mm) and drill the holes using the hole saw supplied.
• Check that the edges are perfectly smooth and deburred (use abrasive paper for example).
• Clip together the lower and upper parts of the cell collar on the pipe at the holes, respec ng the water fl ow direc on
(use the "EU" Ø50 reducer for a Ø50 mm pipe).
• Posi on the top transparent part of the cell (presence of a foolproof loca ng notch), posi on the locking ring on the
thread of the upper collar by aligning the point ( ) of the collar with the arrow of the collar ( ), then  ghten  rmly
by hand (do not use a tool).
• Connect the cell power cord in compliance with the wire colour codes (red, black and blue connector(s)) and then  t
the protec ve cap.
• For Ei² 12, GenSalt OE 10 or Ei² Expert 10 models, the second red connector will not be connected; leave it as it is before
posi oning the protec on cover.

• The cell must always be the last element placed on the pool return pipe (see diagram).
• It is always recommended to install the cell on a by-pass. This assembly is MANDATORY if the  ow is in
excess of 18 m³/hour to avoid head loss.
• If you installed the cell on a by-pass, it is recommended to  t a check valve downstream from the cell
instead of a manual valve, to avoid any risk of incorrect con gura on which could result in poor circula on
inside the cell.
• If the instruc ons on the loca on and orienta on of the cell are not complied with, there could be a
dangerous build-up of pressurised gas which could cause damage, personal injury or even death.

An "AUS" reducer and a black gasket are supplied in the installa on kit. They are intended for 1 1/2" (= 48
mm) pipes. However, the black gasket can be used instead of the original gasket if the pipe is not standardised
(diameter smaller than DN 50 or DN 63).
2.4 Installing the  ow switch (Ei² Expert only)
The fl ow switch and its  xture collar (Ø50 mm) must impera vely be installed on the piping close to the cell and upstream
from it. Use the threaded adapter and Tefl on tape supplied to install the fl ow switch on its  xture collar.
• Cell installed on a by-pass: the fl ow switch must be installed on the cell by-pass between the upstream isola on valve
and the cell itself.
• Cell installed in line: the fl ow switch must be installed just in front of the cell and a er a possible valve.
• A ach the fl ow switch using using the clamping nut only (screw by hand!).
Securing
nut
• Failure to comply with these instruc ons could lead to the destruc on of the cell! The manufacturer cannot
be held liable in this case.
• The  ow switch has a direc on for installa on (arrow indicated on it showing the  ow direc on for the
water). Make sure that it is correctly placed on its  xture collar so that it stops the salt water chlorinator
produc on when  ltering is stopped ("No  ow" displayed showing the absence of  ow, see “5.
Troubleshoo ng”).
2.5 Electric connec ons
2.5.1 Connec ng the control box
The salt water chlorinator can be connected in compliance with the applicable standards in the country of installa on.
Ei² - GenSalt OE: Mandatory connec on: directly coupled to the pool  ltra on system (the appliance is only supplied with
power when a  ltering cycle is running).
Ei² Expert:
• Preferred connec on: the appliance is permanently plugged in to the power supply (power supply protected by a 30
mA residual current circuit breaker).
• Possible connec on: directly coupled to the pool  ltra on system (the appliance is only supplied with power when a
 ltering cycle is running).
==> When all connec ons (electrical and hydraulic) have been made, reconnect the mains power supply to power on the
appliance.
• Failure to comply with these instruc ons could lead to the destruc on of the cell! The manufacturer cannot
be held liable in this case.
• Whichever connec on is used, it is mandatory to programme the Ei² Expert opera ng  mes (called
"Timers") (see “3.2.5 “SUMMER” and “WINTER” modes and se ng the “Timers””).

2.5.2 Connec on to an electric roller shu er
If the pool is   ed with an electric roller shu er, it can be connected to the chlorinator using a dry contact so that
the la er automa cally adapts its chlorine produc on when the shu er is closed (see “3.2.3 “LOW” mode: chlorine
produc on reduced to 10 % if the pool is covered”).
• Make sure the appliance is powered o .
• Remove the 12 screws securing the cover and remove it (take care not to disconnect the ribbon cables).
• Unscrew the dedicated cable gland  ghtening ring (at the bo om of the control box) and remove the plug to feed
through the cable from the shu er. Tighten the cable gland  ghtening ring.
• Connect the cable from the shu er to the "POOL+" and "POOL-" connectors on the printed circuit board.
• Close the box according to the  ghtening order shown on the following diagram (9 long screws for the perimeter of
the box and 3 short screws for the bo om of the box). The protec on ra ng of the box for water ingress (IPX5) may be
a ected if this procedure is not strictly observed.

3.2.1 Chlorine produc on ac vated
When chlorine produc on starts, the "Start..." message is displayed on screen for about 6 seconds. "CHLORINATION" is
then displayed, indica ng that the appliance is producing chlorine.
3.2.2 "BOOST" mode: chlorine produc on increased to 100 % for 24 h
In certain cases the pool may need higher than normal chlorina on (stormy weather, high number of bathers, etc.).
"BOOST" mode is used to increase chlorine level quickly.
• Press bu ons and simultaneously: "BOOST" is displayed on the screen and 100 % chlorine produc on
starts.
• To stop "BOOST" mode, press .
When "BOOST" mode is ac vated, the rated chlorine produc on se ngs are temporarily overridden and the
Ei² Expert chlorinator will operate for a total of 24 hours at 100 % chlorine produc on. The number of days will
therefore depend on the Ei² Expert opera ng  mes (see “3.2.5 “SUMMER” and “WINTER” modes and se ng
the “Timers””).
3.2.3 "LOW" mode: chlorine produc on reduced to 10 % if the pool is covered
If the pool has a covering system (shelter, shu er, cover, etc.), "LOW" mode is designed to adapt chlorine produc on to
situa ons where the pool is covered (lower needs). Its purpose is to limit chlorine produc on to 10%.
If chlorina on is set to 0% when closing the shu er, "LOW" mode will keep the 0% se ng.
This mode is also called "Shu er" mode.

3.2.5 "SUMMER" and "WINTER" modes and se ng the "Timers"
"Timer" programming is used to de ne the appliance opera ng  mes within the opera ng  mes of the
 ltering system. The daily opera ng  mes must be suffi cient to correctly treat the water. Ei² Expert proposes
default se ngs for Timers 1 and 2. They can be customised (see “3.2.5.b Programming the  mers according
to the modes”).
A reminder of the calcula on rule: the ideal daily  ltering  me is obtained by dividing the required pool
water temperature (measured in °C) by 2.
Example: for water at 28 °C,  me = 28/2 = 14 hours per day
The Ei² Expert chlorinator can store 2 seasonal opera ng modes called by default "SUM" and "WIN". The
following se ngs can be customised for each mode:
- the appliance opera ng  mes, i.e. the " mers": T1 (Timer 1) and T2 (Timer 2)
- the required chlorine produc on rate: 10%, 20%, 30%,... up to 100%.
STANDBY = Appliance opera ng status
T = "Timer" mode (always ac ve)
SUM = "Summer" opera ng mode
80 % = chlorine produc on rate
14:25 =  me in the 24-hour format
3.2.5.a Mode selec on: "SUMMER" or "WINTER"
• Press 4  mes to set the clock. "SUM" starts to fl ash.
• Use the and bu ons to choose "SUM" or "WIN" mode, then press the bu on to return to the home
screen.
3.2.5.b Programming the  mers according to the modes
The  mes of Timers 1 and 2 cannot overlap. In addi on, the  me range of Timer 1 must precede that of Timer
2.
TE1 / TE2 = Timer in "summer" mode No. 1 / Timer in "summer" mode No. 2
08:00-12:00 = Opera ng  me range of Timer No. 1
14:00-18:00 = Opera ng  me range of Timer No. 2
• Press 4  mes to set the clock. "SUM" starts to fl ash.
• Select the mode to be customised "SUM" or "WIN" using the and bu ons, then press to save and
move to the  mer se ngs screen.
• Use the and bu ons to set the minutes of the  me when Timer 1 must end, then press to save.
• Use the and bu ons to set the hours of the  me when Timer 1 must end, then press to save.
• Use the and bu ons to set the minutes of the  me when Timer 1 must start, then press to save.
• Use the and bu ons to set the hours of the  me when Timer 1 must start, then press to save.

3.2.6.b Polarity inversion
The choice of polarity inversion cycles may a ect the cell life me (+/- 15 %). Ask your professional retailer
for advice in case of doubt.
The chlorinator is equipped with a smart polarity reversal system designed to prevent scaling of the
electrode plates. However, cleaning may be required in regions where the water is very
hard (default se ng = 5 hours).
Ei² Expert o ers a choice of 3 inversion cycles:
• 3 hours: for water with very high calcium carbonate content (TH > 40 °f or 400 ppm)
• 5 hours: for normal water (20 < TH < 40 °f or 200 ppm < TH < 400 ppm)
• 7 hours: for water with low calcium carbonate content (TH < 20 °f or 200 ppm).
• From the home screen, press the and bu ons for 5 seconds.
• Press the bu on once. The polarity inversion cycle hours start to fl ash.
• Use the and bu ons to select the required cycle.

4. Maintenance
4.1 Washing the pool  lter (backwash)
The appliance must be switched o when washing the  lter. When the appliance is on ( ltra on on), press
the bu on for 5 seconds to switch it o .
A er cleaning the  lter, switch the appliance on again by pressing the bu on (press and release). It will
resume normal opera on (produc on slaved to  ltra on for Ei² and GenSalt OE).
For Ei² Expert, produc on will occur as per the  mer se ngs.
The manufacturer cannot be held liable in case of incorrect handling.
4.2 Cleaning the electrode
The appliance is equipped with a smart polarity inversion system designed to prevent the electrode plates from
scaling. However cleaning may be required in regions where the water is very hard.
• Turn o the chlorinator and the  ltering system, close the isola on valves, remove the protec on cover and disconnect
the cell power cable.
• Unscrew the  ghtening ring and remove the cell. The ring is crenelated thus allowing a lever to be used in the event of
it jamming. Place the cell backwards and  ll it with a cleaning solu on so that the electrode plates are immersed.
• Leave the cleaning solu on to dissolve the scale deposit for about 15 minutes. Dispose of the cleaning solu on at an
approved waste recycling site, never pour into the rainwater drainage system or into the sewers.
• Rinse the electrode using clean water and put it back on the cell  xture collar (there is a foolproof marker to ensure
correct alignment).
• Re t the  ghtening ring, reconnect the cell cable and re t the protec ve cover. Open the isola on valves and restart
the  ltering system and chlorinator.
• If you do not use a commercially available cleaning solu on, you can manufacture it yourself by carefully
mixing 1 volume of hydrochloric acid with 9 volumes of water (Warning: always pour the acid into the water
and not the opposite and wear suitable protec ve equipment!).
• Make sure that the se ng of the polarity inversion cycles is adapted to the pool's water hardness. See
“3.2.6.b Polarity inversion” to change them.
4.3 Winterising
The chlorinator has a protec ve system to limit chlorine produc on under bad opera ng condi ons such as cold
water (winter) or a lack of salt.
• Ac ve winterising =  ltering opera onal in winter: below 10 °C it is preferable to switch o the chlorinator. Above this
temperature you can leave it running.
• Passive winterising = lower water level and drained piping: leave the electrode dry in its cell with its isola on valves
open.
