SETTING THE RIGHT CHLORINE OUTPUT AND FILTRATION TIME
Your E-SERIES Chlorinator must be run every day to ensure that your pool is correctly sanitised. As the sun dissipates
chlorine, running times are higher in the summer compared to the winter. AstralPool recommend that you initially run you
chlorinator at maximum output.
Summer
You should set your Chlorinator to operate for 8 to 10 hours per day. Ideally, run it for 4-5 hours in the morning (say 8-
12pm) and 4-5 hours in the evening (say 6.00-11pm).
In extremely hot weather it may be necessary to extend the running time if you find that the free chlorine level is too low.
To prevent consumption of chlorine by sunlight, try adding Cyanuric Acid as recommended by your local pool professional.
Additional benefit will be gained by operating your chlorinator and pump into the evening when the strong sunlight has
abated.
Chlorine is most effective when the pH of your pool water is 7.4. The electro-chemical process of the chlorinator, (change
salt into chlorine) will automatically raise the pH of your pool water, so it is very important to check your pH weekly and
adjust as necessary.
Winter
You should set your Chlorinator to operate for 6 to 8 hours per day. Again, running it in the morning and evening is
preferable.
Checking Chlorine Level
Ideally, check you Chlorine level after the morning operating period. The free chlorine residual level should be somewhere
between 1 and 3 parts per million. Increase or decrease the output of the Chlorinator to get the right residual chlorine level.
It may also be necessary to adjust the operating period if you are running at minimum or maximum output.
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 E-SERIES 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 AstralPool 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 chlorinator, until the correct quantity of salt has been added and dissolved
in your pool water.
