INST 473 ZODIAC EL24 Salt Chlorinator V10.18
7
STABILISER
As previously mentioned, sunlight rapidly dissipates the amount of free chlorine in your pool.
Chlorine stabiliser greatly reduces this effect. Without stabiliser, you may need to run your
Chlorinator and filtration system up to 16 hours per day or longer.
Keep the Stabiliser reading between 30 and 60ppm.
pH Level
You should keep you pH level between 7.0 and 7.4 for fibreglass pools and 7.2 to 7.6 for other
pools.
Total Alkalinity
The ideal range is between 80 and 120 ppm.
Salt Level
Although salt is not consumed by the chlorinator, salt is lost during backwashing, and when your
pool overflows due to rain or splashing. The correct salt level is important to cell life and the
effective operation of your chlorinator. Salt level should be maintained around 6,000ppm but should
never be allowed to fall below 4,000ppm.
A typical pool of around 50,000 litres requires 300kg of salt to initially set-up the pool to 6,000ppm.
A low salt level warning is indicated on your EL-24 Chlorinator if the salt level drops. If Low Salt is
indicated, check again in 24 hours and then if it is still indicated, add two 25kg bags of salt to the
shallow end of your pool. Run the filtration system for approx. 6 hours to help mix the salt in the
pool. It can take up to a day for the salt to fully dissolve.
If the low salt light is still on, then you should get your pool water tested. If the Salinity is above
6000ppm then you may need to have your Chlorinator checked.
Warning:
Never add salt directly to the skimmer box. This practice should be avoided as it
allows very high concentrations of salt to be passed through your filtration and other pool
equipment
.
CHLORINATOR MAINTENANCE AND TROUBLESHOOTING
If the supply cord is damaged, it must be replaced by Zodiac or its service agent or a similarly
qualified person in order to avoid a hazard.
Warning:
Operating the chlorinator with less than 3000 ppm of dissolved salt in the water
may cause damage to the cell and will void the warranty. Never start the chlorinator, until
the correct quantity of salt has been added and dissolved in your pool water.
CELL MAINTENANCE
Your EL-24 Chlorinator has an automatic cleaning feature that under normal conditions, will keep
the cell plates clear of deposits of salt and calcium.
The cell has a negative charge sensor that monitors the flow and salt levels of the water. This
sensor is designed to be fail safe. As it is negative charge deposits of calcium or other debris may
be deposited on it and cause it to indicate a low salt or no flow condition. Should a low salt
condition be indicated, have your salt level checked at your local pool shop. If the low salt condition
persists, or a no flow condition is indicated when the supply pump is operating, you may need to
manually clean your chlorinator Cell.
