• Which kind of salt to use:
For use within the European Union, salt must be from an authorized salt supplier registered with
the European Chemicals Agency (ECHA) - visit echa.europa.eu.
*
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). However, it will take
a 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 the salt to create the
sanitizer. So, 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). The optimal
level is 3000 ppm.
A too low salt level will reduce the efficiency of the saltwater system and result in low sanitizer
production. A high salt level may generate a salty taste to the pool water (this may occur at a salt
level above 3500-4000 ppm). Too high of a salt level may damage the power supply and cause
corrosion to pool metal fixtures and accessories. The Salt Table page of this manual, shows the
correct dosage of salt needed. The salt in the pool is constantly recycled. Salt loss occurs only
when pool water is physically removed from the pool. Salt is not lost due to evaporation.
• Adding Salt
1
. Switch on the unit, then press and hold both and button for 5 seconds, the LED
flashes “FP”. The unit is now in a Filter pump working mode and switch the filter pump on to
start the water circulation.
2
. Keep the Saltwater System turned 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
. Avoid clogging the filter by not adding 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, press button
until you hear a “beep”, code “00” flashing (see “System Operation” section steps 2 to 4) 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 will need to lower the salt concentration. The only way to do so, is to partially drain the pool
and refill it with fresh water. Drain and refill approximately 20% of the pool’s water until the “Code
92” disappears.
• Pool Volume Calculation
* The European Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) requires that
salt (sodium chloride) used as a precursor for on-site generation of active chlorine by electrolysis
must be registered by the salt supplier with the European Chemicals Agency (ECHA), and such
supplier must be included on ECHA's list of authorized suppliers (Article 95 list).
