OPERATING LIMITS
As with any pool, it’s important that the ltration time is long enough to maintain a good chemical
balance in the pool water, including pH, alkalinity and calcium levels.
The only special requirement to use a salt chlorinator is maintaining proper levels of salt and
stabiliser.
To get the most out of your pool, it is important to maintain these levels in order to avoid corrosion
and scale deposits. We therefore recommended that you test all of the basic parameters of the
water at least once per week.
In addition, we recommended getting your pool water tested by a professional at least twice per
season.
Your local pool store can provide you with the chemicals and steps to take to adjust the chemical
properties of the water.
Don’t forget to let the store know that you use a salt chlorinator.
Check your values and correct them at least once a week:
Parameter Target values Comments
Salinity 3 to 4 g/l Once the salt is dissolved in the water (+/- 24 to
48h), salt concentration will only vary slightly over
the course of the season.
pH level 7.2 to 7.4 Please note, a pH above 7.8 suppresses the
disinfecting properties of hypochlorite.
Free chlorine concentration From 0.5 to 3.0 ppm Measurements must be taken from around the
return inlets when the chlorinator is switched on,
preferably in the morning and out of direct sunlight.
! important !
Stabilizer rate
(Cyanuric Acid)
From 20 to 50ppm Hypochlorite is a relatively unstable disinfectant.
With too low a level of stabilizer, the hypochlorite
will turn back into salt too quickly without having
had enough time to disinfect.
Conversely, with too high a level of stabilizer, the
hypochlorite will be blocked.
Be careful, if the level of stabilizer is much too high,
the pool will have to be partially drained to add
water without stabilizer.
Additional tests
Total alkalinity (TA) From 80 to 150 ppm This level measures the concentration of mineral
salts (carbonates, bicarbonates, hydroxides) in the
water. It stabilizes / buers the water balance. High
TA levels interfere with the eects of pH regulation
and scale deposits may begin to appear.
Water hardness From 150 to 300 ppm Water hardness represents the amount of calcium
carbonate present in your water.
In addition, temperature plays a major role in the correct usage of your chlorinator:
Water temperatures lower than 10°C will render the system inoperative (E2 warning will be
displayed)
Water temperatures higher than 32°C will reduce the eectiveness of hypochlorite. The addition
of chlorine tablets is therefore recommended for consistently high temperatures; do not place
chlorine tablets directly into the skimmer, use a oating dispenser.
WARNING - the presence of iron in your water (ferruginous water) may lead to
rust deposits in your pool and require the use of a metal sequestrant - please
consult a professional.
