General Points; Water Chemistry - Hayward AquaRite AQR-PRO-75LSE Manual Del Usuario

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.
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.
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.
