Pro LS Rev. D GENERAL POINTS The AquaRite Pro LS is an automatic chlorine generation system for pool or spa sanitization. The operation requires a low concentration of salt (sodium chloride) in the pool water. These levels are low enough that it normally will not be tasted. The AquaRite Pro LS automatically sanitizes your pool by converting the salt into free chlorine which kills bacteria and algae in the pool. Chlorine will revert back to sodium chloride after killing bacteria. These reactions will continuously recycle virtually eliminating the need to add sanitizing chemicals to your pool. The only time you may need to add more salt to the pool is when water is replenished due to backwashing, draining, or splashing (not evaporation). The AquaRite Pro LS is designed to handle the purification needs of most residential swimming pools up to 90 m³ (AQR- PRO-75LSE). Check local codes for other restrictions. The actual amount of chlorination required to properly sanitize a pool varies due to bather load, rainfall, temperature, and the pool's cleanliness. The AquaRite Pro LS is used with the AQL-CHEM to provide a fully integrated chemistry solution for your pool. With the AQL-CHEM installed, the AquaRite Pro LS senses the pool's ORP and pH levels and automatically generates the correct amount of chlorine to keep your pool properly sanitized. The AquaRite Pro LS can also control pH by introducing acid into the pool when needed. A dedicated on/off control output is available for pH dispensing devices using 230 V. The AquaRite Pro LS and AQL-CHEM products offer the user a complete automated system controlling both sanitization and pH balance. NOTE: It is not recommended to use the AquaRite Pro LS to generate bromine. NOTE: Before installing this product as part of a saline water purification system in a pool or spa using natural stone for coping or for immediately adjacent patios/decking, a qualified stone installation specialist should be consulted regarding the appropriate type, installation, sealant (if any) and maintenance of stone used around a saline pool with electronic chlorine generator in your particular location and circumstances. WATER CHEMISTRY The table below summarizes the levels that are recommended by Hayward. The only special requirements for the AquaRite Pro LS are the salt level and stabilizer. It is important to maintain these levels in order to prevent corrosion or scaling and to ensure maximum enjoyment of the pool. Test your water periodically. Your authorized AquaRite Pro LS dealer or most pool stores can provide you with the chemicals and procedures to adjust the water chemistry. Be sure to tell the pool store that you are using an AquaRite Pro LS chlorine generator.

CHEMICAL IDEAL LEVELS

Salt 1.2 to 2.5 g/l (ideal 1.5 g/l) Free Chlorine 1.0 to 3.0 ppm pH 7.2 to 7.6 Cyanuric Acid (Stabilizer) 20 to 30 ppm (25 ppm best) Add stabilizer only if necessary Total Alkalinity 80 to 120 ppm Calcium Hardness 200 to 300 ppm Metals 0 ppm Saturation Index -.2 to .2 (0 best) Saturation index The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the pool water "balance". Your water is properly balanced if the Si is 0 ±.2. If the Si is below -0.2, the water is corrosive and plaster pool walls will be dissolved into the water. If the Si is above +0.2, scaling and staining will occur. Use the chart below to determine the saturation index.USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Page 5 of 16 AquaRite

How to use: Measure pool pH, temperature, calcium hardness, and total alkalinity. Use the chart above to determine Ti, Ci and Ai into the above equation. If Si equals 0.2 or more, scaling and staining may occur. If Si equals -0.2 or less corrosion or irritation may occur. - 0.2

CORROSIVESCALING Salt Level Use the chart on page 6 to determine how much salt in kgs need to be added to reach the recommended levels. Use the equations below if pool size is unknown.

(pool size in meters) 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 ideal salt level is between 1.2 - 2.5 g/L with 1.5 g/L being optimal. If the level is low, determine the number of M³ in the pool and add salt according to the chart on page 6. A low salt level will reduce the efficiency of the AquaRite Pro LS and result in low chlorine production. A high salt level can cause the AquaRite Pro LS to shutdown and may begin to give a salty taste to your pool. The salt in your pool/spa is constantly recycled and the loss of salt throughout the swimming season should be small. This loss is due primarily to the addition of water because of splashing, backwashing, or draining (because of rain). Salt is not lost due to evaporation. Type of Salt to Use It is important to use only sodium chloride (NaCl) salt that is greater than 99% pure (EN 16401). Use only salt for electronic chlorine generator usually available in 25 kg bags. Do not use rock salt, salt with yellow prussiate of soda, salt with anti-caking additives, or iodized salt. How to Add or Remove Salt For new plaster pools, wait 10-14 days before adding salt to allow the plaster to cure. Turn the circulating pump on and add salt directly into the pool. Brush the salt around to speed up the dissolving process. Do not allow salt to pile up on the bottom of the pool. Run the filter pump for 24 hours with the suction coming from the main drain (use pool vac if there is no main drain) to allow the salt to evenly disperse throughout the pool. The salt display may take 24 hours to respond to the change in salt concentration. The only way to lower the salt concentration is to partially drain the pool and refill with fresh water. Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together. Use the chart on page 6 to determine how much stabilizer must be added to raise the level to 25 ppm. Use stabilizer only if necessary.USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Page 6 of 16 AquaRite

RUN: When in RUN mode, the AquaRite Pro LS will produce chlorine according to the desired output % or ORP setting (when AQL-CHEM is used) for the entire filtering/pumping cycle. The AquaRite Pro LS can only produce chlorine when RUN is selected and the filter pump is running. STOP: When in STOP mode, the AquaRite Pro LS is prevented from energizing the electrolytic cell. In this position there is no chlorine generation. NOTE: To service any of the pool equipment or the AquaRite Pro LS, the power must be turned off at the circuit breaker. SUPER CHLORINATE: (if AQL-CHEM sensing is NOT used) When you have an abnormally high bather load, a large amount of rain, a cloudy water condition, or any other condition which needs a large amount of purification to be introduced, SUPER CHLORINATE should be selected. This electronically “super chlorinates” (shocks) the water for a user selectable period of 1-96 hours (filter pump must be on during this time) or until the power has been turned off, whichever comes first. The AquaRite Pro LS will automatically revert back to the previous desired output % setting at the end of the super chlorinate period.

This function is NOT reversible, be careful OPERATION Assuming that the water chemical levels are in the recommended range, there are three factors that you can control which directly contribute to the amount of chlorine the AquaRite Pro LS will generate:

1. filter run time each day (hours)

2. the desired output % setting or ORP setting (when using AQL-CHEM)

3. the amount of salt in the pool

The filter pump timer should be set so that entire volume of pool water passes through the filter each day. For pools with high chlorine demand, the timer may have to be set longer to generate enough chlorine.USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Page 11 of 16 AquaRite

Pro LS Rev. D If AQL-CHEM sensing is NOT used. To find the optimum desired output % setting, start at approximately 50%. Test the chlorine level every few days and adjust the setting up or down accordingly. It usually takes 2-3 adjustments to find the ideal setting for your pool/spa and after that, it should only take minor, infrequent adjustments. Because the chlorine demand of the pool increases with temperature, most people find they have to adjust the desired output up at the peak of the summer and down during the colder periods. The AquaRite Pro LS automatically stops generating when the pool water temperatures drops below 12°C. This is usually not a problem because bacteria and algae stop growing at this temperature. You can override this low temperature cutoff by using the Super Chlorinate function for a day. Prevent overchlorination during cold weather: Check chlorine levels periodically. Most pools require less chlorine during cold weather and the desired output % setting should be lowered accordingly.

MAINTAINING THE AQUARITE PRO LS SYSTEM

To maintain maximum performance, it is recommended that you open and visually inspect the cell every 3 months or after cleaning your filter. The AquaRite Pro LS will remind you to do this by displaying the message “Inspect/Clean Cell” after approximately 500 hours of operation. The AquaRite Pro LS electrolytic cell has a self cleaning feature incorporated into the electronic control’s logic. In most cases this self cleaning action will keep the cell working at optimum efficiency. In areas where water is hard (high mineral content) and in pools where the water chemistry has been allowed to get "out of balance", the cell may require periodic cleaning. Servicing and Cleaning the AquaRite Pro LS Cell Turn off power to the AquaRite Pro LS before removing the electrolytic cell. Once removed, look inside the cell and inspect for scale formation (light colored crusty or flaky deposits) on the plates and for any debris which has passed through the filter and caught on the plates. If no deposits are visible, reinstall. If deposits are seen, use a high pressure garden hose and try to flush the scale off. If this is not successful, use a plastic or wood tool (do not use metal as this will scratch the coating off the plates) and scrape deposits off of plates. Note that a buildup on the cell indicates that there is an unusually high calcium level in the pool (old pool water is usually the cause). If this is not corrected, you may to have to periodically clean the cell. The simplest way to avoid this is to bring the pool chemistry to the recommended levels as specified. Mild Acid Washing: Use only in severe cases where flushing and scraping will not remove the majority of deposits. To acid wash, turn off power to AquaRite Pro LS. Remove cell from piping. In a clean plastic container, mix a solution of water to acetic or phosphoric acid (Like descaler for coffee machine). ALWAYS ADD ACID TO WATER - NEVER ADD WATER TO ACID. Be sure to wear rubber gloves and appropriate eye protection. The level of the solution in the container should just reach the top of the cell so that the wire harness compartment is NOT submerged. It may be helpful to coil the wiring before immersing the cell. The cell should soak for a few minutes and then rinse with a high pressure garden hose. If any deposits are still visible, repeat soaking and rinsing. Replace cell and inspect again periodically. WINTERIZING The AquaRite Pro LS electrolytic cell and flow detection switch will be damaged by freezing water just as your pool plumbing would. In areas of the country which experience severe or extended periods of freezing temperatures, be sure to drain all water from the pump, filter, and supply and return lines before any freezing conditions occur. The electronic control is capable of withstanding any winter weather and should not be removed. Spring Start-up DO NOT turn the AquaRite Pro LS on, until the pool water chemistry has been brought to the proper levels.

SPA ELECTROLYTIC CELL FLOW SWITCH IN-FLOOR CLEANER Preparing Pool Water Refer to page 4 for recommended chemical levels. The pool's chemistry must be balanced BEFORE activating the AquaRite Pro LS. NOTE: If the pool does not have new water, add 1 liter of metal remover and 1 liter of non-copper based algaecide to the pool, per manufacturer's instructions. This ensures a quick, troublefree transfer to the AquaRite Pro LS system. Mounting the AquaRite Pro LS Control The AquaRite Pro LS is contained in a raintight enclosure that is suitable for outdoor mounting. The control must be mounted a minimum 3.5 meters horizontal distance (or more, if local codes require) from the pool/spa. The control is designed to mount horizontally on a flat surface with the knockouts facing downward. Because the enclosure also acts as a heat sink (disperses heat from inside the box), it is important not to block the four sides of the control. Do not mount AquaRite Pro LS inside a panel or tight enclosed area. If an AQL-CHEM kit will be used, take into consideration the space necessary for mounting the unit as well as running the plumbing lines from the AQL-CHEM's probe cell to the pool plumbing. Refer to the AQL-CHEM manual for specific mounting instructions. Plumbing Ensure that the AquaRite Pro LS installation does not constitute a cross connection with the local potable water supply. Consult local plumbing codes. The AquaRite Pro LS is packaged with a flow switch that installs into the supplied 50 mm saddle clamp. The chlorinator cell, sold separately, installs into the supplied 50 mm cell unions. The flow switch and cell should be plumbed in the return line to the pool/spa. The preferred installation is after (downstream) all the pool equipment (filter, heater, solar, etc.). For proper plumbing, refer to the overview diagram above.USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Page 13 of 16 AquaRite
