4.4 Water Preparation - IMPORTANT
4.4.1 Calcium
-
A calcium hardness of at least
250ppm in your pool water is essential when operating the e-clear
system. This is necessary to maintain the
conductivity of the water, thereby ensuring operational
efficiency.
-
The procedure of raising the calcium hardness in the pool water should be carried out by the
installer or by a qualified pool technician making use of the prescribed test equipment.
CAUTION-the e-clear system will not operate properly without this pre-requisite calcium hardness.
4.4.2 pH
-
The correct operating pH in the pool water, for the e-clear system to operate efficiently, is in the
range of
6.8- 7.2. If the pool water's pH is allowed to rise above 7.3 for longer than 48 hours, the
water may turn green.
-
A pH range of 6.8- 7.2 must be maintained if the pool water is to clean and clear. pH may need to
be adjusted as often as, every second day, or as little as once a week. This is dependent on
individual swimming pool conditions (e.g. Amount of sun, leaves or people entering the pool)
-
E-clear accepts no responsibility for staining due to irregular maintenance of pool PH levels.
4.4.3 Copper Residual and Silver Residual
-
A copper residual of 0.5ppm in the pool water is necessary to maintain Bacteria/algae free
conditions and maximum performance of the oxidation process. For systems with silver electrodes, a
silver residual of 50ppb is necessary. The copper and silver electrodes are linked, thus if the copper
residual reaches 0.5ppm then the silver residual will be 50ppb.
