Zodiac : D Series

<< Previous | Next >>

Common salt (sodium chloride) is made up of two elements, sodium and chlorine. When your Zodiac D Series is installed,
a measured quantity of salt is dissolved in the pool water to make it slightly salty. As part of the daily filtration cycle, the pool water is passed through the Zodiac electrolysis cell to produce chlorine which is dissolved instantly into the water.
Your D Series also produces ozone in the cell as a by-product.

In simple, non-technical terms, the chlorine instantly starts to destroy bacteria, viruses and

algae, and in doing this reverts to dissolved salt. This cycle continues with more new

chlorine being produced from the salt water in the electrolysis cell, sanitising the pool,

and changing once more back to dissolved salt.

Everyday, when the Zodiac D Series and the filtration system are switched on, dust and

debris are trapped by the filter and the D Series sanitises the water to make if safe and

sparkling clean.

IMPORTANT.

To ensure your D Series works at maximum efficiency, regularly check and maintain the

chemistry of your pool.
