• Clean and rinse filters regularly to maintain steady flow through the Smart Cell and prevent false readings or low output.
• Keep salt levels within the recommended range and allow full circulation time after any adjustment for accurate system calibration.
• Inspect the Smart Cell for scale buildup; clean or replace as needed to maintain efficient chlorine generation.
• Run a weekly oxidizer shock to improve water clarity and reduce combined chlorine buildup.
• Avoid adding chemicals not approved for salt systems to prevent damage or sensor interference.
