Salt & Pool Water Volumes
Use only Sodium Chloride Salts
Use only sodium chloride (NaCl) salt that is at least 99.8% pure. It is also acceptable to use water
conditioning salt pellets (the compressed forms of evaporated salt), but it will take longer time for them
to dissolve. Do not use iodized or yellow (yellow prussiate of soda) colored salt. Salt is added to
the pool water and the electrolytic cell uses this salt to create chlorine, the purer the salt the better the
performance of the electrolytic cell.
Optimum Salt Levels
The ideal salt level in the pool water is between 2500-3500 ppm (parts per million) with 3000 ppm
being optimal.
A too low salt level will reduce the efficiency of the Saltwater System and result in low chlorine
production. A high salt level may begin to generate a salty taste to your pool water (this may occur at a
salt level above 3500-4000ppm). Too high of a salt level may damage the power supply and cause
corrosion to pool metal fixtures and accessories. The following “salt table” shows the quantity of salt to
use. The salt in the pool is constantly recycled. Salt loss is due only to pool water physically removed
from the pool. Salt is not lost due to evaporation.
How to Add or Remove Salt
Adding Salt
1. Depress the ON button on the filter pump switch to circulate pool water.
2. Keep the Saltwater System “OFF”.
3. Determine the amount of salt to be added (see “Salt Table”).
4. Evenly spread the proper amount of salt around the inside perimeter of the pool.
5. To avoid clogging the filter, do not add salt through the skimmer.
6. Brush the pool bottom to speed up the dissolving process. Do not allow salt to pile up on the
bottom of the pool. Run the filter pump 24 consecutive hours to thoroughly dissolve the salt.
7. After 24 hours and if all the salt is dissolved, turn on the Saltwater System and set the saltwater
pool system to desired operating time (see “Operating Time Table”).
Removing Salt
If too much salt has been added, the unit will beep and display “code 92” (see “Alarm Codes”). You
need to lower the salt concentration. The only way to lower the salt concentration is to partially drain the
pool and refill with fresh water. Drain and refill approximately 20% of the pool’s water until the “Code 92”
disappears.
