UV LS is a pool treatment system. It is an effective water treatment method for your pool that uses electrolysis and hydrolysis of salt water. To operate, the salt chlorinator requires a low salt concentration (sodium chloride) in the pool water. The AquaRite

UV LS automatically disinfects your pool by converting salt into free chlorine, which destroys bacteria and algae present in the water. The UV module is composed of two 55 W lamps. The UV rays counteract the development of algae, deactivate bacteria, viruses and micro- organisms, and eliminate chloramines. The chlorine recombines into sodium chloride. This permanent cycle means you do not need to treat your pool manually. The AquaRite

UV LS is the healthiest and best-performing water treatment option for all residential pools. The quantity of chlorine required to treat a pool correctly varies depending on the number of swimmers, precipitation levels, the number of hours of filtration, the temperature and cleanliness of the water, etc. NOTE: Before installing this product on the filtration system of a pool or spa with an adjacent natural stone terrace or deck, consult a qualified installer who will advise you on the type, installation, sealant (if any) and maintenance of stone that can be laid around a saline pool.

Preparing the pool water To prepare the pool water to enable the AquaRite

UV LS to function, its chemical composition must be balanced and salt added. This must be done BEFORE turning on the AquaRite

UV LS. Certain adjustments to the chemical balance of the pool can take several hours. The procedure must therefore be started well before the AquaRite

UV LS is turned on. Adding salt: Add the salt several hours or, if possible, a day before turning on the Compass Salt Water salt chlorinator. Ensure that the recommended amount of salt is used. Measure the salt content 6 to 8 hours after adding the salt to the swimming pool. NOTE: If the water in the pool is not fresh and/or if it is liable to contain dissolved metals, use a metal remover, according to the manufacturer’s instructions. If your water has previously been treated with a product other than chlorine (bromine, hydrogen peroxide, PHMB, etc.), neutralize this product or replace all the water in the pool. Salt concentration Use the following table to determine the quantity of salt (in kg) needed to reach the recommended concentrations. Use the formulae below if you do not know the volume of your swimming pool.

(pool dimensions, in m) Rectangular Length x width x average depth Round Diameter x diameter x average depth x 0.785 Oval Length x width x average depth x 0.893 The salt concentration depends on the unit model. Reference: 3 g/l for standard salinity units, and 1.5 g/l for low salinity units (displayed in % on the screen). A low salt level reduces the efficiency of the AquaRite

UV LS and causes a reduction in disinfectant production. The unit will display the message “Low” on the screen. There is no risk of premature deterioration of the box and cell. There is no risk of damage to the box or the cell due to a high salt concentration. The effect of this is simply that it gives your pool water a salty taste. As the salt in your pool is constantly being recycled, the loss of salt during the season is minimal. The salt concentration is primarily reduced when the water level must be topped up due to splashing or backwashing, or when rain adds fresh water to the pool. Salt is not lost through evaporation. Type of salt to use Use only salt that complies with standard EN 16401 and is intended for salt chlorinators. Use only sodium chloride (NaCl) that is more than 99% pure. Do not use food-grade salt, iodized salt, salt containing yellow prussiate of soda or salt containing anti-caking additives. How to add or remove salt For new pools, let the plaster dry for ten to fourteen days before adding salt. Start up the filtration pump, then add salt directly into the intake side of the pool. Make the water circulate to speed up the dissolution process. Do not allow salt to accumulate at the bottom of the pool. Run the filtration pump for 24 hours, opening the main drain valve fully to allow the salt to dissolve evenly throughout the pool. The only way to lower the salt concentration is to partially empty the pool and refill it with fresh water. Always check the stabilizer (cyanuric acid) when checking the salt concentration. The corresponding concentrations tend to decrease together. Refer to the following table to determine the quantity of stabilizer required in order to achieve a concentration of 25 ppm. Add stabilizer only if necessary. Do not add stabilizer to indoor pools.EN English Only use spare parts supplied by Hayward brands

UV LS Chemical water balance The water must be balanced manually BEFORE the device is started up. The following table summarizes the concentrations recommended by Hayward. Your water should be checked regularly to maintain these concentrations and minimize surface corrosion or deterioration.

CHEMISTRY RECOMMENDED CONCENTRATIONS

Salt 1.5 g/l Free chlorine 0.5 to 2.5 ppm pH 7.2 to 7.6 Cyanuric acid (Stabilizer) 20 to 30 ppm max. (Add stabilizer only if necessary) 0 ppm in indoor pool Total alkalinity 80 to 120 ppm Water hardness 200 to 300 ppm Metals 0 ppm Langelier index -0.2 to 0.2 (preferably 0) Quantity of stabilizer (CYANURIC ACID in kg) required for 25 ppm Current salt concentra- tion (ppm) Volume of water in the pool in m³

The device is designed to be connected to a protected outlet at all times. The AquaRite

UV LS must not be disconnected unless the pool equipment is undergoing maintenance or the pool is to be closed (wintering). If the water parameters are within the recommended ranges, the device can be started up. 5b. Commissioning of the device 5a.

UV LS 5f. Filtration control 1 Filtration modes. 2 Manual: Allows the ltration process to be turned on and off manually. 3 Filter cleaning: This mode is used to backwash the lter. 4 Automatic: In this mode, ltration is turned on and off according to the start and end times. These time slots must be programmed within a single day (midnight to midnight). 4 Smart: mode may be activated if and only if the temperature probe has been activated. This mode is based on the automatic mode, with its three ltration intervals, but the ltration times are adjusted according to the temperature. This is done by setting two temperature parameters: the maximum temperature, above which the ltration times will be determined by the time slots, and the minimum temperature, below which ltration will be reduced to ve minutes, the minimum operation period. Between these two temperatures, the ltration times will be staggered linearly. The antifreeze mode can be activated to turn the ltration on if the water temperature falls below 2°C. 5 Heating: mode may be activated if and only if the temperature probe and heat pump are both activated and congured. This mode acts in the same way as the automatic mode, but it can also operate via a relay that controls the temperature. The set point temperature is determined in this menu and the system operates with a hysteresis of one degree (for example: if the set point temperature is 23°C, the system will start up when the temperature falls below 22°C and shut down only when it rises above 23°C). Heating control OFF: The heating operates only during the congured ltration periods. Heating control ON: Keeps the ltration on after the ltration period has expired if the temperature is below the set point temperature. When the setpoint temperature is reached, the ltration and heating stop and only resume when the next programming period begins. 6 Intelligent: mode may be activated if and only if the temperature probe and heat pump are both activated and congured. In this mode, the user has two operating parameters: select the required water temperature and the minimum ltration time (minimum two hours and maximum 24 hours). The ltration will operate for at least ten minutes every two hours to check the temperature. The minimum ltration time selected is divided into twelve sections that are added to these ten minutes. Example 1: Over twelve hours, the time is divided between the twelve times a day when the ltration starts up to check the temperature. Example 2: (12 hours x 60 minutes) / 12 = 60 minutes every two hours. This is the ltration and heating period every two hours. If the programmed ltration period ends and the required temperature has not been reached, the ltration and heating remain on until the required temperature is reached. To minimize the number of hours during which ltration operates each day, this additional time will be deducted from the next ltration periods occurring during the rest of the day. (See the chart below).

The electrolysis and measurements will not activate unless the ltration is running.Thermal circuit breaker / SwitchContactor Pump

UV LS 6a. Installing and starting up the pH option

1 pH probe calibration: Recommended once a month during the pool season. 2 Calibration using buffer solutions (buffer solutions pH7 / pH10 / neutral). Follow the instructions that appear on screen 3.3 Calibration procedure involving 7 steps.4 Manual calibration: Allows you to calibrate the probes using 1 point (without buffer solution) – recommended only for adjusting small deviations in readings.5 Without taking the probe out of the water, use the Up/Down arrows to adjust the measurement displayed so that it coincides with the reference value (photometer or other measuring instrument).1 Open the cover and connect the pH CHIP card to the PH slot (see section 3C). The pH reading and the Measures menu will be displayed automatically, to congure the setpoint and carry out the calibration.2 Connect the dosing pump to the pH terminal using a cable gland (see section 3C and 3D) and close the cover.3 Install the probe with its mount in the pipe and connect the probe to the unit (see section 3D). Follow the instructions for the pH pump to inject the liquid.• The probe has a lifetime of 1 year. We recommend calibrating it every month during the season the pool is in use.Connecting the pH dosing pump1 Connect the suction strainer: insert the (transparent) PVC suction tube all the way into the conical connector of the suction strainer, tighten the clamping nut and position the suction strainer in the bottom of the container holding the chemical to be dosed.2 Connect the suction and delivery tubes: loosen the pump clamping nuts, insert the (transparent) PVC suction tube on the left and the (opaque) PE delivery tube on the right all the way into the conical connector, and tighten the clamping nut.3 Connect the injection valve: loosen the nut, insert the (opaque) PE delivery tube all the way into the conical connector, and tighten the clamping nut. Screw the valve on to the mount provided on the cell using Teon tape.Operation of pH corrector dosing pump:The pump starts up depending on the setpoint entered in the menu Measures - Setpoints - acid pH (setpoint < water pH). By default, the maximum dosing time is 120 minutes to avoid acidication of the water (AL3). The proportional method is used for injection: 10 minutes ON (variable depending on the difference between the measured value and the setpoint) + 5 minutes OFF (xed). Both acid and alkali can be dosed (contact your installer). The pump is equipped with an on/off switch. The Santoprene tube of the peristaltic pump has a lifetime of 2 years. We recommend changing it once a year.Installing and preserving the pH probe:1 The pH probe is “wet” packed and protected by a plastic cap. The probes must always remain wet. If the probes are allowed to dry, they will be permanently unusable (not covered by the warranty) and the pH test kit will be ineffective.2 Remove the pH probe from its protective plastic cap and set the cap aside for later use (wintering or maintenance).3 Put the probe into the probe holder or double probe holder (depending on the options ordered) and tighten the probe mounts to ensure watertightness.4 Check that the probes are watertight at startup. Seal with Teon, if required.5 After installation, check that the probes are constantly in contact with the pool water. When the ltration pump is not running (even for long periods), the water remaining in the pipes is sufcient to protect the probes. The sanitization products (acid, etc.) must be injected last on the water return line, after any equipment (heater, cell, etc.). Seal with Teon. All types of acid (sulphuric, hydrochloric or a blend) are compatible. We recommend using sulphuric acid. Always begin the calibration procedure with a calibration reset. The default value is 7.2.

6. CONNECTING AND CONFIGURING PERIPHERALS

The use of dry acid such as sodium bisulfate to adjust the pH of the swimming pool is not recommended, especially in arid regions where pool water is subject to signicant evaporation and is not commonly diluted with mains water. Dry acid can cause a build-up of by-products that can damage your chlorinator.EN EnglishOnly use spare parts supplied by Hayward brands

The ORP reading and the Measures menu will be displayed automatically, to congure the setpoint and calibrate the probe.2 Install the probe with its mount in the pipe, connect the probe to the unit (see section 3D), and close the cover. The probe has a lifetime of 1 year. We recommend calibrating it every month during the season the pool is in use.Operation of the ORP module:By default, when the ORP option is connected, the electrolysis cell starts up as soon as the measured ORP value falls below the setpoint.Installing and preserving the ORP probe:1 The ORP probe is «wet» packed and protected by a plastic cap. The probes must always remain wet. If the probes are allowed to dry, they will be permanently unusable (not covered by the warranty) and the ORP test kit will be ineffective.2 Remove the ORP probe from its plastic protective cap and set the cap aside for later use (wintering or maintenance).3 Put the probe into the probe holder or double probe holder (depending on the options ordered) and tighten the probe mounts to ensure watertightness.4 Check that the probes are watertight at startup. Seal with Teon, if required.5 After installation, check that the probes are constantly in contact with the water in the pool. When the ltration pump is not running (even for long periods), the water remaining in the circuit may be sufcient to protect the probes. The product (liquid chlorine, etc.) injection device must be installed last on the water return line, after any equipment (heater, cell, etc.). Seal with Teon. The default value is 700 mV.Setting the ORP levelThe ORP level tells you the oxidation potential, i.e. the disinfectant capacity of the water. Setting the ORP set point is the last step in setting the AquaRite UV LS.To nd the optimum ORP level for your pool, follow the steps below:1 Start up the pool ltration system (the salt in the pool must be evenly dissolved).2 Add chlorine to the swimming pool until it reaches 1 to 1.5 ppm. This level is achieved with approximately 1 to 1.5 g/m of water.The pH level must vary between 7.2 and 7.5.3 After 30 min. check that the level of free chlorine in the pool (manual DPD1 test kit) is between 0.8 and 1.0 ppm.4 Look at the ORP value on the screen and enter it as the ORP set point.5 The next day, check the free chlorine level (manual DPD1 test kit) and the ORP level. Increase / reduce the setting, if required.Remember to check all your water parameters at regular intervals (2-3 months) (see table Chemical water balance) and adjust the ORP set point according to the steps listed above.EN EnglishOnly use spare parts supplied by Hayward brands

You can scan the QR code directly in the app to register your pool. Once you have registered, you can monitor all your AquaRite UV LS parameters remotely with Hayward PoolWatch.Only WiFi networks with a frequency of 2.4 GHz are accepted by the module. 98 10 11EN English Only use spare parts supplied by Hayward brands

During the rst 10-15 days, your system will require more attention: - Check that the pH remains at the ideal level (7.2 to 7.4). - If the pH is exceptionally unstable and uses a lot of acid, check the alkalinity (see table Chemical water balance). If the balance is highly unstable, contact your pool installer/builder. REMEMBER that the system needs a certain amount of time to adapt to your pool and will require additional chemicals during the rst 3-5 days. The pool must be regularly maintained and the skimmer baskets emptied whenever necessary. Also check that your lter is not clogged. ADD WATER: It is preferable to add water via the skimmers so that it passes through the cell before entering the pool. Remember to check the salt percentage after adding water. DOSING PUMPS: Regularly check the acid level to ensure that the pump does not run dry. The dosing pump must be checked and serviced at regular intervals. The Santoprene tube of the peristaltic pump has a lifetime of 2 years. We recommend that you change it once a year. Servicing the pH probe The probe must be clean and free from oil, chemical deposits and contamination to function properly. As it is in continuous contact with the water in the pool, the probe may need to be cleaned weekly or monthly, depending on the number of bathers and other specic characteristics of your pool. A slow response, more frequent pH calibration and inconsistent readings indicate that the probe needs to be cleaned. To clean the probe, turn off the power to the AquaRite

UV LS. Unplug the probe connector from the unit, unscrew the probe and carefully remove it from the chamber. Clean the probe bulb with a soft toothbrush and regular toothpaste. A household washing-up liquid detergent may also be used to remove any oil. Rinse with fresh water, replace the Teon tape on the threads, and reinstall the probe. If the probe continues to give inconsistent readings or requires excessive calibration after it has been cleaned, it should be replaced. The lifetime of the probes is 1 year. We recommend that you calibrate them every month during the season the pool is in use. Servicing and cleaning the cell Turn off the main power supply to the AquaRite

UV LS before removing the cell. Once it has been removed, examine the in- side of the cell for any traces of scale (whitish brittle or aky deposits) and debris stuck to the plates. If no deposits are visible, put the cell back in place. If deposits are visible, try to remove them with a garden hose. If this method is unsuccessful, use a plastic or wooden tool to remove deposits stuck to plates (do not use a metal tool as this will damage their coating). A build-up of deposits on the cell indicates an exceptionally high concentration of calcium in the pool water. If you cannot nd a solution to this situation, you will have to clean the cell at regular intervals. The best way to avoid this problem is to maintain the chemical composition of the water at the recommended concentrations. Acid washing: This should only be done in severe cases where ushing will not remove most of the deposits. To acid wash, turn off the main power supply to the AquaRite

UV LS. Remove the cell from the piping. In a clean plastic container, make up a solution of water and acetic or phosphoric acid (such as that used to remove scale from a coffee machine). ALWAYS ADD ACID TO WATER – NEVER ADD WATER TO ACID. Be sure to wear rubber gloves and protective goggles for this operation. The level of the solution in the container should just reach the top of the cell, so that the wire harness compartment IS NOT under water. It may be helpful to coil up the wire before submerging the cell. Allow the cell to soak for a few minutes, then rinse it with a garden hose. If the deposits are still visible, soak and rinse again. Put the cell back and examine it from time to time. Probe storage The end of the probe must always be in contact with water or a solution of KCl. If it is removed from the measuring chamber, it should be stored in the plastic cap provided (lled with water). If the storage cap has been mislaid, the probe should be stored separately in a small glass or plastic container with its end immersed in water. The probe must always be in a frost-free environment.EN English Only use spare parts supplied by Hayward brands

No display Check the connection cable between the display and the control box. Check that the 4A fuse is not defective (located inside the control box). Check the power supply: 210-230 V 50 Hz. If the problem persists, contact your pool installer/builder. Excessive chlorine Check and/or adjust the chlorine production setting. If your pool has an automatic ORP control system, check the ORP setting. Check the ORP probe and calibrate, if necessary. The hydrolysis has not reached the required production rate Check the concentration of salt in the water (depending on the model). Check the condition of the cell (it may be dirty or covered in scale). Clean the cell according to instructions. Check the ow switch and clean if necessary. Check that the cell is not worn (contact your pool installer/builder). Cell scaled up in under a month Very hard water with high pH and total alkalinity (balance and adjust the pH and total alkalinity of the water). Check that the system automatically changes polarity (see display). Impossible to attain a free chlorine level of 1 ppm Increase the ltration time. Increase the chlorine production rate. Check the concentration of salt in the water (see table Chemical water balance). Check the level of isocyanuric acid in the pool (see table Chemical water balance). Check that the reactive agents in your test kit are not out of date. Adjust the chlorine production according to the temperature and the number of pool users. Adjust the pH to ensure that it is always below 7.8. Alarm AL3: pH dosing pump stopped The maximum time allowed to attain the pH set point has been reached. The pH acid dosing pump is stopped to avoid overdosing and acidifying the water. Please carry out the following checks: Check that the can of liquid pH is not empty. Check whether the pH read on the machine corresponds to the pH in the pool (use a pH analysis kit). Otherwise, please calibrate the pH probe or replace it, if necessary. Check that the pH pump is running normally. Check the correction time setting. To make this message disappear and reset the dosing, press on the pH reading circle for 3 seconds. The screen indicates LOW Check the water balance and salinity. Check that the cell is free of scale and clean it if necessary. See “The hydrolysis has not reached the required production rate”. Water temperature too low. White akes in the pool This occurs when the water is unbalanced and very hard. Balance the water, check the cell and clean it, if necessary. The screen indicates FLOW Check the ow switch and the gas detector. Check that the lter pump is working. Check that the pipes are not obstructed (valve closed, basket or strainer full, etc.). Check that the 4A fuse is not defective. Changing the battery Unplug the cables that are screwed to the “extension” circuit board. Unscrew the “extension” circuit board. Unscrew the black cover of the “main” circuit board. Change the battery (CR2032 type). Screw the black cover, the “extension” circuit board, and the cables back in place.EN English Only use spare parts supplied by Hayward brands
