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.
Salt
Salt (Low salt)
Free chlorine
pH
Cyanuric acid

Total alkalinity
Water hardness

Saturation index
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.
• WARNING – Chemicals can cause internal and external burns. To avoid death, serious injury and/or damage to equipment,
wear personal protective equipment (gloves, goggles, mask, etc.) when servicing or maintaining this device. The treatment products
must be installed and/or stored in an adequately ventilated place.

Use: Measure the pH of the pool water, the temperature, water hard-
ness and total alkalinity. Use the table above to determine Ti, Ci and
Ai in the formula shown above. If the Si is equal to 0.2 or more, stains
may appear. If the Si is equal to -0.2 or less, corrosion or deterioration
may occur.
