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
Free chlorine
pH
Cyanuric acid
(Stabilizer)
Total alkalinity
Water hardness
Metals
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. This device must be installed in an
adequately ventilated place.

Use: Measure the pH of the pool water, the temperature, water hardness 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.
