❹ Pool Preparati On; I Water Balance - Zodiac GenSalt OT Series Instructions For Installation And Use Manual

4.1 I Water balance

The water used must originate from a supply network compliant with Directi ve 98/83/EC on the quality of water intended
for human consumpti on. To achieve opti mum water treatment, be sure to measure and adjust the values in line with the
following recommendati ons:
4.1.1 Seasonal «restart» analysis
- Stabiliser (cyanuric acid) (<30 mg/L, ppm): the stabiliser protects the chlorine against the destructi ve acti on of U.V
light from the sun. Excessive stabiliser levels may block chlorine's disinfecti ng acti on and cause the water to go bad.
- Metals (Cu, Fe, Mn) (
cause indelible stains.
4.1.2 Monthly analysis
- TH (10-30°f) or (100 - 300 mg/L CaCO
value may vary signifi cantly depending on locati on.
- TAC (8-15°f) or (80 -150 mg/L CaCO
stabilize the pH. It is important to adjust TAC before pH.
4.1.3 Weekly analysis
- pH (7.0 - 7.4): the pH level measures the acidity or basicity of the water. A pH level between 7.0 and 7.4 will
preserve the pool equipment and ensure eff ecti ve disinfecti on. Below is the Taylor's watergram method to adjust
the pH value:
Alcalinity of the water
Taylor's watergram
- Free chlorine (0.5 - 2 mg/L or ppm): this amount of free chlorine ensures that the water is disinfected and
disinfecti ng.
Contact your dealer to determine the type of correcti ve product or automati c regulati ng device to
use to adjust the values.
