GENERAL
The AquaRite + is a system that controls the equipment and it is used in conjunction with a salt chlorinator for treating swimming pools.
The AquaRite + allows you to control the filtration system (pump) as well as the peripheral equipment (heat pump, lighting, etc.).
It can also be used to treat your pool effectively by salt water electrolysis. For the chlorinator to function, it requires a low concentration of salt (sodium chloride) in the pool water. The AquaRite + automatically disinfects your pool by converting the salt into free chlorine which kills the bacteria and algae in the pool. The chlorine reverts back to sodium chloride. This continuous cycle means that there is no need to treat your pool manually. The AquaRite + is suitable for treating most residential swimming pools. The quantity of chlorine required to treat a swimming pool correctly varies according to the number of bathers, the rainfall, water temperature and the cleanliness of the pool…
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.
NOTE: 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 significant evaporation and is not commonly diluted with mains water. Dry acid can cause a build-up of by-products that can damage your chlorinator.

Wall-mounted installation
Fix the box and the measuring chamber on the wall (optional). The box must be installed in the equipment room (dry, temperate, ventilated). Caution, acid vapours can cause irreversible damage to your device. Position the treatment product tanks accordingly.
The AquaRite + must be fitted a minimum horizontal distance of 3.5 m (or more, if required by local regulations) from the pool, within 1 m of a protected outlet and within 4.5 m of the planned cell location. The box must be placed vertically on a flat surface, with the cables downwards. As this box is also used to evacuate heat (heat dissipation from internal components), it is important that the four sides of the box remain unobstructed. Do not to install the AquaRite + behind a panel or in an enclosed space.
Before installing the control unit in the intended location, check that the power cord can reach the protected outlet and that the cell cable can reach the intended cell location.

Disconnect the pool filtration pump before starting the installation. The system must be installed in accordance with the standards currently in force in the country of installation. The control box must be fitted a minimum horizontal distance of 3.5 m (or more, if required by local regulations) from the pool, within 1 m of a protected outlet and 4.5 m of the planned cell location. Install and use the product at an altitude below 2000 m.
The flow switch must be installed on the return pipe directly in line with and upstream of the cell and the treatment product injection point. Allow a 25 cm straight section before the flow switch. A hole should previously have been drilled in the pipe to allow the flow switch to pass through. Screw the flow switch into the saddle clamp, taking care to seal with Teflon. Then install the clamp on the pipe. The flow switch must be installed in the direction of operation to ensure that it is tripped by the flow from the filtration pump.
The device used to inject the treatment products (acid, etc.) must be installed last on the water return line, after any equipment (heater, cell, etc.). A hole should previously have been drilled in the pipe to allow the treatment product to pass through. Install the saddle clamp and screw the injection valve into the saddle clamp using the adapter provided. Seal with Teflon. Use the transparent PVC hose for suction (between the acid tank and the peristaltic pump) and the semi-rigid white polyethylene tube for injection (between the peristaltic pump and the injection valve).
All the metal components of the swimming pool can be connected to the same earth as per local regulations

Assigning speeds Whatever the filtration mode (Manual, Automatic, Smart, Heating or Intelligent), one of the three operating speeds (V1, V2 or V3) can be selected, thus providing a high degree of flexibility for setting and adjusting the water flow according to the equipment. The device will first have to be configured to take the variable-speed pump into account (see the section entitled “Setting the pump type”). The speed assigned to the “antifreeze” mode is V2. Note: We should point out that the speed of all pool devices requiring a minimum water flow that is appropriate to their correct operation must be set manually before being stored in the memory and used by the AquaRite + (heat pump, chlorinator, etc.). See the variable-speed pump instructions for setting all the parameters related to its operation and safety. Connecting the Wifi option (Optional) The Wifi module must be installed in the equipment room (dry, temperate, ventilated) and located within reach of the wireless network cover to which it will be connected. Switch off the device before connecting the module. Plug the Wifi module connector into the RF / WIFI connector on the AquaRite + card.
Installing the screen wall-mounting kit (not supplied) Remove the screen from the box and unplug it. Plug the extension connector into the DISPLAY connector on the AquaRite + card. Plug the other end of the extension into the screen after first passing the cable through the wall bracket. Fit the cover (supplied) over the front of the AquaRite + to replace the screen.

Preparing the pool water To prepare the pool water to enable the AquaRite + to function, its chemical composition must be balanced and salt added. This must be done BEFORE turning on the AquaRite +. Certain adjustments to the chemical balance of the pool can take several hours. The procedure must therefore be started well before the AquaRite + is turned on.
Adding salt: Add the salt several hours or, if possible, a day before turning on the AquaRite +. 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.

Rectangular Round Oval

m3
(pool dimensions, in m)
Length x width x Average depth
Diameter x Diameter x Average depth x 0.785
Length x width x Average depth x 0.893

The ideal salt concentration is between 2.7 and 3.4 g/l, with 3.2 g/l being the optimum value. If the level is low, determine the volume (m3) of the pool and add salt in accordance with the following table. A low salt level reduces the efficiency of the AquaRite + and reduces chlorine production. A high salt concentration can cause the AquaRite + to fail and make your pool water taste salty. As the salt in your pool is constantly being recycled, the loss of salt during the season is minimal. Salt is mainly lost when water has to be added due to splashing, backwashing or draining (because of rain). Salt is not lost through evaporation.
Type of salt to use Use only salt intended for chlorinators in conformance with EN 16401. 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 to be added to bring the concentration to 25 ppm. Add stabilizer only if necessary. Do not add stabilizer to indoor pools.

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 Salt Salt (Low salt) Free chlorine pH
Cyanuric acid (Stabilizer)
Total alkalinity Water hardness Metals Saturation index

Recommended CONCENTRATIONS 3.2 g/l 1.5 g/l 1.0 to 3.0 ppm 7.2 to 7.6 20 to 30 ppm max. (Add stabilizer only if necessary) 0 ppm in indoor pool 80 to 120 ppm 200 to 300 ppm 0 ppm -0.2 to 0.2 (preferably 0)

Saturation index The saturation index (Si) gives us information about the calcium content and alkalinity of the water; it is a water balance indicator. Your water is correctly balanced if the Si is 0 ± 0.2. If the Si is below -0.2, the water is corrosive and the coating on the pool walls may be damaged. If the Si is above +0.2, stains may appear. Use the table below to determine the saturation index.

1 Filtration modes.

2 Manual: Allows the filtration process to be turned on

and off manually.

3 Filter cleaning: This mode is used to backwash the

filter.

4 Automatic: In this mode, filtration is turned on

according to the start and end times set in the time

slots. The time slots always operate on a daily basis.

5 Smart*: This mode is based on the automatic mode,

with its three filtration intervals, but the filtration times

are adjusted according to the temperature. This is

done by setting two temperature parameters: the

maximum temperature, above which the filtration

times will be determined by the time slots, and the

minimum temperature, below which filtration will be

reduced to five minutes, the minimum operation period.

Between these two temperatures, the filtration times

will be staggered linearly. The antifreeze mode can be

activated to turn the filtration on if the water temperature

falls below 2°C.

6 Heating : 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 filtration periods configured.
Heating control ON: Keeps the filtration on after

the filtration period has expired if the temperature is below the set point temperature. When the setpoint temperature is reached, the filtration and heating stop and only resume when the next programming period begins.

7 Intelligent*: In this mode, the user has two operating parameters: Select the required water temperature and the minimum filtration time (minimum two hours and maximum 24 hours). The filtration will operate for at least ten minutes every two hours to check the temperature. The minimum filtration time selected is divided into twelve sections that are added to its ten minutes. Example 1: Over twelve hours, the time

Intelligent mode

10 min

is divided between the twelve times a day when the filtration starts up to check the temperature. Example 2: (12 hours x 60 minutes) / 12 = 60 minutes every two hours. This is the filtration and heating period every two hours. If the programmed filtration period ends and the required temperature has not been reached, the filtration and heating remain on until the required temperature is reached. To minimize the

number of hours during which filtration operates each day, this additional time will be deducted from the next filtration periods occurring during the rest of the day. (See the chart below).

Setting the redox level (redox kit option)
The redox level tells you the oxidation potential, i.e. the disinfectant capacity of the water. Setting the redox set point is the last step in setting the AquaRite +. To find the optimum redox level for your pool, follow the steps below: 1) Start up the pool filtration 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/m3 of water). The pH level must vary between 7.2 and 7.5. 3) After 30 min. Check whether the level of free chlorine in the pool (manual DPD1 test kit) is between 0.8 and 1.0 ppm. 4) Look at the redox value on the screen and enter it as the redox set point. 5) The next day, check the free chlorine levels (manual DPD1 test kit) and the redox level. Increase / reduce the setting, if required. Remember to check all your water parameters at regular intervals (2-3 months) (see table) and adjust the redox set point according to the steps listed above.

SERVICING
During the first 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). 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 first 3-5 days.
The pool must be regularly maintained and the skimmer baskets emptied whenever necessary. Also check that your filter 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 percentage of salt 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.
Servicing the probes The probes must be clean and free from oil, chemical deposits and contamination to function properly. As they are in continuous contact with the water in the pool, the probes may need to be cleaned weekly or monthly, depending on the number of bathers and other specific pool characteristics. A slow response, more frequent pH calibration and inconsistent readings indicate that the probes need to be cleaned. To clean the probes, turn off the power to the AquaRite +. Unplug the probe connectors from the control box, unscrew the probes and carefully remove them from the chamber. Clean the probe bulb (white ring at the bottom of the body of the probe) 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 Teflon tape on the threads, and reinstall the probes. If the probes continue to give inconsistent readings or require excessive calibration after they have been cleaned, they should be replaced.
Servicing and cleaning the AquaRite + cell Turn off the main power supply to the AquaRite + before removing the cell. Once it has been removed, examine the inside of the cell for any traces of scale (whitish brittle or flaky deposits) and debris stuck to the plates. If no deposits are visible, reinstall the cell. 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 find 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 flushing will not remove most of the deposits. To acid wash, turn off the main power supply to the AquaRite +. 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.
Wintering The AquaRite + cell, the flow switch, probes and pool piping run the risk of being damaged if the water freezes. In regions that experience long periods of cold weather, be sure to drain all the water from the pump and filter and from the supply and return pipes before winter. Do not remove the control unit.
Probe storage The end of the probes must always be in contact with water or a solution of KCl. If they are removed from the measuring chamber, they should be stored in the plastic caps provided (filled with water). If the storage caps have been mislaid, the probes should be stored separately in small glass or plastic containers with their ends immersed in water. The probes must always be in a frost-free environment.

TROUBLESHOOTING GUIDE
No display Check that the On / Off switch is on. Check the connection cable between the display and the control box. Check that the external 250 mA fuse is not defective. Check the power supply: 210-230 V 50 Hz. If the problem persists, contact your pool installer/builder.
Excessive chlorine Low electrolytic cell current. If your pool has an automatic redox control system, check the redox setting. Check the redox probe and calibrate, if necessary.
Electrolysis does not reach maximum intensity Check the concentration of salt in the water. Check the condition of the cell (it may be dirty or covered in scale). Clean the cell according to instructions. Check the flow 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 0.8 ppm Increase the filtration time. Increase the chlorination production rate. Check the concentration of salt in the water. Check the level of isocyanuric acid in the pool (see table). Check that the reactive agents in your test kit are not out of date. If the temperature or the number of users increases. If the pH is above 7.8, it must be adjusted.
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 to avoid equipment failure: 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. To delete this message and reset the dosing, press the “Return” key.
Chlorinator display indicates LOW Water lacks conductivity. Check the water balance and salinity. Check for scale on the cell. See “Electrolysis does not reach maximum intensity”.
White flakes in the pool This occurs when the water is unbalanced and very hard. Balance the water, check the cell and clean it, if necessary.
