7. “Inspect Cell” LED illuminated
Remove and inspect the cell for scaling. If the cell is scaled, follow the directions on page 8
for cell cleaning. If the pool has the proper amount of salt and the “Inspect Cell” LED is still
illuminated, the cell may be depleted and needs to be replaced.
8. Possible causes of low chlorine or no chlorine
• The BLH main switch is in the OFF position.
• Desired output % level setting is too low.
• Low stabilizer (Cyanuric Acid). Chlorine spacing is being produced but the pool
water is unable to hold on to the chlorine, due to low stabilizer.
• The filter pump is switched off or the running time may be to short (8 hours is
recommended for an average sized pool, increases for larger size pools)
• The salt level is too low (below 2500 ppm, Low Salt LED on).
• The salt level is too high (high Salt LED on).
• Low ph. – A lowered (power of hydrogen) or (measurement of alkalinity/acidity)
oxidizes chlorine quickly, making it difficult to maintain desired chlorine levels.
Adjust pH levels to re-balance water.
• Warm pool water increases the demand for chlorine - increase the desired level or
filter run time to meet this higher demand.
• Cold-water (below 50F) can cause the BLH to stop generating (Generating LED
flashing).
• Excessive scaling on cell.
• High level of phosphates in pool water.
• Some yellow algae treatments will use chlorine at a very high rate and deplete the
residual free chlorine. Manually shock the pool if indicated in the directions on the
algae treatment. It still may be a matter of days before the pool returns to “normal”
and chlorine tests will show the desired 1-3ppm free chlorine reading.
9. “PCB” is displayed, and all 4 LED lights are illuminated.
A possible printed circuit board fault has been detected. Call for service.
