Frequently Asked Questions - AquaRite UV LS HAYWARD

What does the 'LOW' display on the screen mean?

This indicates a salt deficiency, a scaled cell, or water temperature too low. Check salinity, clean the cell, and check the temperature.

Why does the screen show 'FLOW'?

Water flow is insufficient. Check that the filtration pump is running, valves are open, and the flow detector is not obstructed.

How to clean the electrolysis cell?

Turn off power, remove the cell. Rinse with clean water. For stubborn deposits, use a diluted acetic or phosphoric acid solution, following safety instructions.

How to calibrate the pH probe?

Use pH 7 and pH 10 buffer solutions. In the Measurements menu, select pH Calibration, then Buffer (2pt) and follow the on-screen instructions.

What is the recommended salt concentration?

1.5 g/l for low salinity models, 3 g/l for standard models. A low level reduces efficiency, a high level gives a salty taste without damaging the unit.

How to connect the WiFi module?

Open the cover, plug the module into the WiFi slot. In the Settings > Network menu, select your 2.4 GHz network and enter the password. The LEDs should stay steady.

What to do in case of no display?

Check the connection cable, the 4A fuse inside the box, and the power supply (210-230 V~ 50 Hz). If the problem persists, contact your installer.

How to change the internal battery?

Disconnect the wires from the extension board, unscrew it, then remove the black cover on the main board to access the CR2032 battery. Replace it and reassemble.

The AL3 alarm is displayed, what to do?

This means the maximum pH dosing time has been reached. Check the acid level, pH probe, and dosing pump. Press and hold the pH reading circle for 3 seconds to reset.

What are the wear parts and their lifespan?

Titanium cell: 8,000 h, UV lamp: 8,000 h, seals: 2 years, Santoprene tube: 2 years, probes: 1 year (6-month warranty).

1. GENERAL

The AquaRite ^® 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 microorganisms, 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.

3b. Wall-mounted installation

Mount the unit on the wall. The unit must be installed in the equipment room (dry, mild conditions, ventilated). Caution, acid vapours can cause irreversible damage to your device. Position the treatment product tanks accordingly.

Unplug the pool filter pump before you begin the installation. The installation must be performed in compliance with the regulations in effect in the country of installation.

The AquaRite® UV LS 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 unit 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 install the AquaRite® UV LS behind a panel or in an enclosed space.

Before installing the 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.

All the metal components of the swimming pool can be connected to the same earth as per local regulations.

3c. Installation and connection of the electronic circuit boards

Connect the AquaRite ^® UV LS to a permanent power outlet.

⚠️: This circuit must be protected by a residual current device (RCD) (residual current: 30 mA max.) and a 16A time-delay circuit-breaker.

4. PREREQUISITES FOR STARTING UP THE HYDROLYSIS

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.

	m3(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.

Quantity of stabilizer (CYANURIC ACID in kg) required for 25 ppm

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 12	0 ppm
Water hardness 200 to	300 ppm
Metals 0 ppm
Langelier index -0.2 to	0.2 (preferably 0)

5. OPERATION

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.

5f. Filtration control

The electrolysis and measurements will not activate unless the filtration is running.

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 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 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.

5 Heating: mode may be activated if and only if the temperature probe and heat pump are both activated and configured. 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 configured filtration periods.

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.

6 Intelligent:mode may be activated if and only if the temperature probe and heat pump are both activated and configured. 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 these ten minutes.

Example 1: Over twelve hours, the time 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).

6. CONNECTING AND CONFIGURING PERIPHERALS

6a. Installing and starting up the pH option

Always begin the calibration procedure with a calibration reset.

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 configure 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 pump

1 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 Teflon 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 acidification 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 (fixed). 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 Teflon, if required.
5 After installation, check that the probes are constantly in contact with the pool water. When the filtration pump is not running (even for long periods), the water remaining in the pipes is sufficient 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 Teflon.
All types of acid (sulphuric, hydrochloric or a blend) are compatible. We recommend using sulphuric acid.

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.

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 Teflon, if required.
5 After installation, check that the probes are constantly in contact with the water in the pool. When the filtration pump is not running (even for long periods), the water remaining in the circuit may be sufficient 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 Teflon.

Setting the ORP level

The 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 find the optimum ORP 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 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.

After connecting a variable speed pump, you can assign a different speed individually to each filtration period, as required. V1: S, V2: M, V3: F Filter cleaning: To clean the filter with a variable speed pump, it is best to use the highest speed (V3).

7. 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 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 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 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 specific 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 Teflon 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 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, 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 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® 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 (filled 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.
