Problem Solution
Water looks clean but there is no chlorine • Confirm that pool water is balanced, total alkalinity is
residual reading. 80 - 150 ppm and pH within 7.2 - 7.8 range.
• Inspect cell for calcium build-up, manually clean
if necessary.
• Check stabilizer (cyanuric acid) levels, 40-100 ppm.
• Increase chlorine output setting.
• Increase DuoClear run time.
• Verify the pump/filtration system are clean and
operating properly.
• Test for salt concentration and add as needed.
• Manually shock the pool.

ation and add salt if necessary. (Water
temperature below 65
° may cause light to illuminate.)
• Inspect electrode for scale build-up, manually
clean if necessary.
