SALT:WHEN & HOW TO ADD IT
Salt:When And How To Add It
When to add salt.
Add salt when indicated on the control panel.The light marked ‘Add Salt’ functions
automatically when extra salt is needed. Note that the ‘Add Salt’ light may switch on at any salt
level between 3000 and 4000ppm, depending upon the water temperature and mains voltage
(see note).This is not a fault but a precaution to ensure that the salt level is never too low.
The salt concentration should normally be around 4000 ppm, but should never be allowed to
fall below 3000 ppm, as this can reduce the life of the cell electrodes.
Salt is not lost through evaporation. Salt is lost with the water splashed out of the pool or
during backwash. Adding fresh water or rainfall to the pool dilutes the salt concentration.
Adding salt may be needed from time to time to maintain an optimum salt level.
NOTE: Even if the salt concentration is around 4000 ppm, the ‘Add Salt’ light may switch ON
if the water temperature drops below 65˚ or mains supply voltage is too low. In this situation,
it may not be possible to set the Chlorine Output to maximum. Addition of more salt to the
pool will allow the Chlorine Output to reach maximum settings.
How much to add.
Use a salt test strip to determine salt level in pool water prior to adding any salt. Capture
water from elbows depth in a container, then use a test strip in this water sample. Previous
regular usage of sodium hypochlorite (liquid chlorine) creates residual salt within the pool and
may bring your salt level close to the required 4000 ppm concentration. Only 99.5% pure
refined salt (sodium chloride) should be used with the Clearwater chlorinator. Add enough
salt to obtain a 4000 ppm concentration.
- In a pool of approximately 13,200 gallons, one (1) 50 lb. bag of salt will increase the salt
concentration by 500 ppm.
- In a NEW pool (where there is no salt residual) of approximately 13,200 gallons, eight
(8) 50 lb bags of salt are required to reach a 4000 ppm concentration.
- Refer to ‘Salt Chart’ on page 18.
IMPORTANT:To avoid damage to your Clearwater chlorinator, never allow
salt level to exceed 13,000 ppm
How to add salt.
Evenly disperse the proper amount of salt around the perimeter of the pool. Run filter for 4-6
hours. Allow 24 hours for salt to fully dissolve. If the ADD SALT light is on after 24 hours, test salt
level and add necessary salt to obtain a 4000 ppm concentration. Even if the salt level is maintained
a 4000 ppm, but water temperature drops below 65˚, the ADD SALT may come on.This is not
cause for concern. For further assistance, consult your pool professional or call 1-888-537-6657.
Note: Do not add salt to the skimmer box.
