1.4 I Operang principle
The chlorinator is composed of an electrolyc cell (containing electrodes) and a control box.
When the salt water from the swimming pool passes through the cell, the current generated by the electrodes
creates an electrolyc reacon which transforms the chloride ions (from the salt in the swimming pool) into chlorine
gas. Chlorine gas is a powerful disinfectant and is instantly dissolved in water. It then reverts back into salt under the
acon of UV radiaon and also because of the need for disinfectant resulng from use of the pool (organic maer).
The chlorinator therefore generates a cyclic reacon designed to produce chlorine.

2❷Installing the salt water chlorinator
2.1 I Installing the electrolyc cell
• The cell must always be the last element placed on the pool return pipe (see § “2.1.1. Installing the cell
and the sensor holder (depending on model)”).
• 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. A ow regulaon valve must be included.
• When the cell is installed on a by-pass, t a check valve downstream from the cell instead of a manual
valve, to avoid any risk of incorrect conguraon and poor circulaon inside the cell.
2.1.1. Installing the cell and the sensor holder (depending on model)
• 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 system.
• The cell's installaon must allow easy access to the installed electrodes.
• Two valves must be installed for isolang the cell from the rest of the installaon, so that maintenance tasks can be
performed without emptying the pool.

• Respect the water ow direcon indicated on the cell.
• The circulaon system must guarantee the minimum required ow (see§ “1.2 I Technical
specicaons”).
• For Ø50 mm pipes, use glue-on PVC adapters of the corresponding diameter.
• Connect the cell power cord following the wire colour codes (red, yellow, and orange connectors) and then ret the
protecve cap (see § “2.1.3. Connecng the cell to the control box”).

8
2.1.2. Connecng the cell and the sensor holder
• Do not glue sensor holder and cell directly together : use a PVC union coupler (not included) between
sensor holder and cell.
It is also possible to use a 6-to-8 cm PVC tube, Ø63 cm, with one beveled end (the one to glue to the cell
inlet) and a PVC sleeve (to glue between the PVC tube and the sensor holder).
For connecng the cell and the sensor holder :
• Degrease the sensor holder, the cell inlet and the PVC union with PVC cleaner (not supplied).
• Glue the sensor holder and the female union and t them into each other as far as it will go. Remove any excess glue
with a damp cloth.
• Glue the cell inlet and the male union and t them into each other as far as it will go. Remove any excess glue with a
damp cloth.

2.2 I Installing the ow switch
• Failure to comply with these instrucons could lead to the destrucon of the cell. The manufacturer
cannot be 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 appliance's
producon when ltering is stopped.
• The ow switch and its xture collar (supplied) must be installed just in front of the cell and aer a
possible valve, in the ow secon that supplies the cell.
• Tighten the nuts by hand.

2.3 I Installing the sensors (pH & pH/ORP, depending on model)
•Never wipe the sensor using a cloth or paper ssue, as this may damage it.
•A badly-installed sensor may give false readings and cause inappropriate operaon of the appliance.
Neither the manufacturer nor the appliance shall be liable in this event.
•Carefully unscrew the protecon tube from the sensor ( ). Keep the protecon tube for storing the sensor over
winter.
•Rinse the end of the sensor with tap water and shake o excess water ( ).
•Loosen the nut xed to the sensor holder ( ).
•Install the pH sensor and/or the ORP sensor (supplied) in the sensor holder so that the sensor located at the end
of the holder is always submerged in the water owing through the piping(). Ensure that the cable is not
tangled.
•To avoid damage, sensor end must be located in the center of the pipe, not further.
•The sensor must always be installed vercally, or where necessary, at a maximum angle of 40°().
•Once the sensor is installed it can be connected to the BNC socket on the control box, see § “2.5.2. Connecng the
control box” ).
• The sensor must then be calibrated, see § “4.4 I Calibrang the sensors (pH or pH/ORP models)”.

3❸ Preparing the pool
3.1 I Balance the water
The water used must originate from a supply network compliant with Direcve 98/83/EC on the quality of water
intended for human consumpon. In order for the water to be treated opmally, carry out measurements and adjust
the values in accordance with the following recommendaons:
Seasonal analyses in "preparaon for re-use"
-Stabiliser (cyanuric acid) (<30 mg/L, ppm): the stabiliser protects chlorine from the destrucve power of the
sun's U.V. rays. Excessive stabiliser can block the disinfecng power of chlorine and turn the water turbid.
-Metals (Cu, Fe, Mn) (± 0 mg/L, ppm): metals damage the metallic parts of the pool (corrosion phenomenon) or
can cause permanent stains.
Monthly analyses
-TH (150 - 300 mg/L CaCO3 , ppm): the TH measures the water hardness (quanty of calcium carbonate), and this
value can vary signicantly depending on the geographical region concerned.
-TA (80 -150 mg/L CaCO3 , ppm): the TA measures the water alkalinity, and this value allows the pH to be
stabilised. It is important that the TA is adjusted before the pH.
Weekly analyses
-pH (7.0 - 7.4): the pH measures the acidity or alkalinity of the water. A pH in the range 7.0 to 7.4 helps to
preserve the pool equipment and maintain eecve disinfecon. Taylor's balance method, as shown below, is
used to adjust the pH value:
TA pH TH
: Mark the value of the TH aer
adjustment.
: Mark the value of the TA aer
adjustment.
: Draw a line between the TH value
and the TA value to determine the pH
value to be adjusted.
Taylor's balance
-Free chlorine (0.5 - 2 mg/L or ppm): this quanty of free chlorine makes the water both disinfected and
disinfecng.
Contact your retailer to determine the type of corrector product or automac control appliance
to be used to adjust the values.
