230 mm 120 mm 340 mm 1.4 I Operang principle The chlorinator is composed of an electrolyc 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 electrolyc reacon 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 acon of UV radiaon and also because of the need for disinfectant resulng from use of the pool (organic maer). The chlorinator therefore generates a cyclic reacon designed to produce chlorine. EN7 2❷ Installing the salt water chlorinator 2.1 I Installing the electrolyc 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 regulaon 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 conguraon and poor circulaon inside the cell.

2.1.1. Installing the cell and the sensor holder (depending on model)

• The cell must be installed on the piping aer the ltraon system, aer any measurement sensors, and aer any heang system.

• The cell's installaon must allow easy access to the installed electrodes.

• Two valves must be installed for isolang the cell from the rest of the installaon, so that maintenance tasks can be performed without emptying the pool.

(*depending on model)

• Respect the water ow direcon indicated on the cell.

• The circulaon system must guarantee the minimum required ow (see§ “1.2 I Technical specicaons”).

• 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 ret the protecve cap (see § “2.1.3. Connecng the cell to the control box”).8

2.1.2. Connecng 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 connecng 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. PVC union coupler PVC sleeve PVC pipe (ed into the cell) Connecng the cell and the sensor holder

In order for the water to be treated opmally, carry out measurements and adjust the values in accordance with the following recommendaons: Seasonal analyses in "preparaon for re-use" - Stabiliser (cyanuric acid) (<30 mg/L, ppm): the stabiliser protects chlorine from the destrucve power of the sun's U.V. rays. Excessive stabiliser can block the disinfecng 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 CaCO

, ppm): the TH measures the water hardness (quanty of calcium carbonate), and this value can vary signicantly depending on the geographical region concerned. - TA (80 -150 mg/L CaCO

, 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 eecve disinfecon. Taylor's balance method, as shown below, is used to adjust the pH value:

: Mark the value of the TH aer adjustment. : Mark the value of the TA aer 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 quanty of free chlorine makes the water both disinfected and disinfecng. Contact your retailer to determine the type of corrector product or automac control appliance to be used to adjust the values.20 3.2 I Add salt Every appliance must be operated with a minimum recommended salt level, see § “1.2 I Technical specicaons”. In order for the chlorinator appliance to operate properly, and to protect the equipment, we recommend using salt (sodium chloride) as per standard EN 16401.

3.2.1. Determining the quanty of salt to be used when installing the appliance

Example: A. Appliance operang with 4 kg of salt per m³ of water (=4g/L or 4000 ppm). B. Appliance operang with 5 kg of salt per m³ of water (=5g/L or 5000 ppm).

• 50m³ pool. The formula: A. 50m

x 4 kg of salt/m³ = 200 kg of salt to be added to the water B. 50m

x 5 kg of salt/m³ = 250 kg of salt to be added to the water

3.2.2. Roune analyses

Check the salt level quarterly and readjust the quanty of salt present where necessary. ==> Method for adding salt to the water

• Start the lter pump to cause the water in the pool to circulate.

• If the appliance has already been installed, switch it o.

• Move around the perimeter of the pool while pouring the required quanty of salt into the water to help disso- luon. Add the salt in stages. It is easier to add salt to make up for an insucient quanty that to dilute the salt present to make up for an excessive quanty.

• Operate the lter pump for 24 hours.

• Aer 24 hours have passed, check that the salinity level in the pool is correct, i.e. 4g/litre or 5g/litre (in the exam- ples cited).

• If the salt level is correct and the appliance has already been installed, switch it on then adjust the desired level of chlorine producon, see § “4.2.1. Adjusng chlorine producon”. Do not add salt directly in the skimmer(s). The appliance must only be switched on when the salt has completely dissolved in the pool. EN21 4❹ Use 4.1 I User interface

Connect & Go automaon unit Chlorinator Connecons:

• It’s strongly advised to use a specic RS485 cable to wire the chlorinator to the Connect & Go power center. If not available, an Ethernet cable can be used (RJ45 connectors cannot be used).

• The Fluidra Connect NN app also provides the possibility to locate professionals who can remotely check the swimming pool, access the measurement history, and display errors through a Fluidra Connect service plaorm. EN35 5.2 I Managing the chlorinator remotely with NN app Before you install the app, you must:

• Use a Wi-Fi-enabled smartphone or tablet,

• Use a Wi-Fi network with a reasonably strong signal when connecng to the chlorinator.

• Have your home Wi-Fi network password at the ready.

• Download the Fluidra Connect NN app from the App Store or Google Play Store.

• Connect to your account or register to create an account (rst-me use).

• Access your pool sengs or adjust setpoints remotely. Access the pool sengs from the "Dashboard" tab Adjust the setpoints from the "Devices" tab36 6❻ Maintenance 6.1 I Sensor maintenance The sensors must be cleaned every 2 months.

• Remove the sensor and the sensor holder.

• Rinse the sensor in tap water for 1 minute.

• Shake it to remove any residual water. To prevent damage to the acve part, do not rub and do not dry with a cloth.

• Brush the juncons and the metal part (Gold) for the ORP sensor using a toothbrush for 1 minute.

• Prepare a soluon of diluted hydrochloric acid by pouring 1 mL (10 drops) of commercially-available hydrochloric acid (HCl 37 %) into 50 mL of tap water (1/2 glass of water).

• Hydrochloric acid is a hazardous chemical that may cause burns, lesions and irritaons. Handle with care and use protecve equipment (gloves, safety glasses, overalls). Refer to the product's MSDS for more informaon.

• Always pour the acid into the water.

• Once cleaning is complete, dispose of the soluon according to the standard in force in the country of use.

• Wash the sensor in the diluted hydrochloric acid soluon for 2 minutes.

• Rinse the sensor in clean water under the tap for 1 minute.

• Shake it to remove any residual water.

• Then calibrate the sensor, see § “4.4 I Calibrang the sensors (pH or pH/ORP models)”.

• Replace the sensor holder and the sensor. EN37 6.2 I Inspecng and cleaning the electrodes The appliance is equipped with a smart polarity inversion system designed to prevent the electrode plates from scaling. The polarity reversal me can be modied, see § “4.3.4. “Reverse direct”: Reversal adjustment for cell cleaning”. However cleaning may be required in regions where the water is very hard.

• Turn o the appliance and the ltraon system, close the isolaon valves, remove the protecon cover and discon- nect 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 (see gure

• Submerge the part containing the electrode plates in a suitable recipient containing a cleaning soluon (see gure

• Leave the cleaning soluon to dissolve the scale deposit for about 10 minutes. Dispose of the cleaning soluon 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 an alignment foolproofer).

• Ret the ghtening ring, reconnect the cell cable and ret the protecve cover.

• Re-open the isolaon valves and restart the ltering system and appliance. If you are not using a commercially-available cleaning soluon, you can make your own by carefully mixing 1 part hydrochloric acid with 10 parts water. (Cauon: always pour the acid into the water and not the opposite and wear suitable protecve equipment).38 6.3 I Peristalc pump maintenance

• To prevent the pump from operang when empty, check the level of the pH-Minus (acid) container every 2 to 12 months, depending on your installaon (see table below). HYDROCHLORIC ACID HYDROCHLORIC ACID SULFURIC ACID Very corrosive atmosphere (installaon not recommended) - Check every 2 to 3 months Corrosive atmosphere (acceptable installaon) - Check every 3 to 6 months Non-corrosive atmosphere (recommended installaon) - Check every 6 to 12 months

• To check the correct operaon of the pH pump: - Ensure the tube is in good condion ( ) and the connecons are correctly sealed, - Check that the tablet holder rotates correctly ( ). EN39 6.4 I Winterising The appliance is ed with a protecon system liming chlorine producon in poor operang condions such as cold water (winter) or low salt.

• Acve winterising = ltering operaonal in winter: below 10°C it is preferable to switch o the appliance. Above this temperature you can leave it running.

• Passive winterising = lower water level and drained piping: switch o the appliance and leave the cell dry in place with any isolaon valves open.

• Winterising the sensors = Keep the plasc sensor tube (which contains a storage soluon) for re-use when win- terising. The sensors must always be stored wet (never dry). They must be stored in the tube lled with a storage soluon of 3 mol/L KCl or at least in tap water. 6.5 I Preparing the pool for new season Required acons:

• Adjust the water level (too much or too lile).

• Check the water parameters: TA/TH/pH/Salinity/Chlorine/Stabiliser/Copper/Metals, and adjust the parameters to obtain a balanced, healthy pool, see § “3.1 I Balance the water”.

• Check the condion of the equipment (pump, lter, chlorinator, electrolyc cell).

• Inspect the sensors, then clean and recalibrate.

• As soon as the salt level reaches the required level (4,000 ppm or 5,000 ppm) and has completely dissolved in the water, restart the salt water chlorinator.40 7❼ Troubleshoong

• The appliance is in standby.

• Unlock the screen (see § “4.1.2. Unlocking the screen”.

• Deacvate the energy saving mode so that the values can be read when the device is in standby, see § “4.3.15. User interface energy saving mode”. Tip: if you require assistance, inform your retailer about the appliance's condion to save me 7.2 I Eects of the stabilising agent on chlorine and ORP A pool ideally has a stabiliser level of 30 ppm and a pH of 7.4. 1 ppm of free chlorine = 700 mV

• The user can therefore adjust the chlorinaon requirements to 700 mV to maintain a level of 1 ppm in the pool.

• If the level of stabiliser rises to 90 ppm, the ORP value will be incorrect and 1 ppm of free chlorine will correspond to 500 mV.

• If the user keeps the setpoint at 700 mV, a chlorine concentraon of 5 ppm will eventually be obtained. CHLORINE LEVEL (PPM) ORP MEASUREMENT (MV) Variaons in the ORP measurement depending on the stabiliser concentraon (pH 7.4, 25°C)*. Setpoint Stabiliser level of 90 ppm Stabiliser level of 30 ppm
