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 and 4-5 hours in
the evening. In
extremely hot weather it may be necessary to extend the running time if you find that the free chlorine level is too low.
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 your Chlorine level after the morning operating period. The free chlorine residual level should be somewhere
between 1ppm and 3 ppm . 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.
3.5 STABILIZER
As previously mentioned, sunlight rapidly dissipates the amount of free chlorine in your pool. Chlorine stabilizer greatly
reduces this effect.
Without stabilizer, you may need to run your Chlorinator and filtration system up to 16 hours per day longer!
Keep the Stabilizer reading between 30 ppm and 100 ppm.
pH Level
You should keep your pH level between 7.2 and 7.8 for fibreglass pools and for other pools.
Total Alkalinity
The ideal range is between 100 ppm 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 4000 ppm but should never be allowed to fall below 3000 ppm.
A typical pool of around 50 000 L (13,210 gals) requires 200 kg (441 lbs) of salt to initially set-up the pool to 4000 ppm.
A low salt level warning is indicated on your VX7T Salt Chlorine Generator if the salt level drops. If Low Salt is indicated, check
again in 24 hours and then if it is still indicated, add two 25 kg (55 lb) bags of salt to the shallow end of your pool. Run the
filtration system for approximately 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 4000 ppm then you may need
to have your Chlorinator checked.
Warning: Some people recommend that you put salt directly in the skimmer box. This is a very bad practice as it allows very
high concentrations of salt to be passed through your filtration and other pool equipment.
