Jandy AquaLink RS / iAquaLink WiFi-Enabled Pool & Spa Automation Controller with Mobile App Control LOW SALT Error Fix: Salt Level Below Minimum

Error code LOW SALT on the Jandy AquaLink RS / iAquaLink WiFi-Enabled Pool & Spa Automation Controller with Mobile App Control means: Salt Level Below Minimum. The connected salt chlorine generator reports the salt concentration in the pool water is below the minimum required for chlorine production (typically below 2,700 ppm) — add pool-grade salt per the chlorinator manual and pool volume calculation; re-test the salt level after 24 hours of continuous circulation to allow full dissolution and mixing; do not add all salt in one location — spread it around the pool perimeter; the chlorinator will not produce chlorine effectively at low salt levels
