8.8.c Adding Salt
Type of Salt to Add
It is important to use Sodium Chloride (NaCl) salt that is greater than 99% pure. Acceptable
types of salt include granular food grade, pool salt, water softener pellets, or solar salt flakes;
these are usually available in 25 to 60 lb bags (11 to 27 kg) at local pool or building supply
outlets. Pool salt or food grade granular salt will dissolve faster than pellets or flakes. Rock salt
and Granular Salt with Iodine or Rust Preventatives should not be used, as these mixtures
contain high levels of impurities and will cause staining. Granular salts containing anti-caking
additives such as YPS (Yellow Prussiate of Soda) or sodium ferrocyanide are not recommended
as they can cause a localized tint to the water or yellow staining of the pool / spa finish.
Amount of Salt Required
Test the water for current salt content first!
The ideal salt range is 3,000 – 35,000 ppm (mg/L). The minimum salt level is 2,500 ppm (mg/L).
However, if so desired, the Pool Pilot
®
can operate with salt levels in excess of 35,000 ppm
(mg/L). Salt levels above 6,000 ppm (mg/L) are not normally recommended, as corrosion issues
may result. Salt levels below 2,000 ppm (mg/L) will reduce the efficiency of the Pool Pilot
®
, and
will result in low chlorine production. Extremely low salt levels below 1,900 ppm (mg/L) will
activate the low salt safety cut off, and will halt chlorine production until salt is replenished to
proper levels. Once the Pool Pilot
®
is programmed to the pool water volume, the controller will
automatically indicate how much salt is required to attain ideal salt levels.
For information on amount of salt to be added relative to the volume of water to be treated vs.
existing salt level, refer to the "Reference" section in this manual. See "Salt Addition Chart" on
page 47.
How to Add Salt to Pool
CAUTION - Failure to heed the following may result in equipment damage.
l
For newly plastered pools, do not use a pool cleaner or vacuum head with wheels, as wheels can leave
track marks.
l
Do not allow granular salt to pile up in one location without brushing, as staining may occur.
The circulation pump should be run continuously until the salt has been fully dissolved –
typically 24 hours. Add salt directly to pool (or spa, if a spa-only installation), and over the main
drain (if main drain is present). If there is no main drain, a vacuum head may be used to
encourage salt circulation. Distributing the salt by brushing is also helpful; brush the salt toward
the main drain (if one is present). Set pump operation to normal run time after salt has fully
dissolved into water.
If the salt level becomes undesirably high, the only way to remove excess salt is to partially drain
the pool / spa and refill with fresh water.
