Check salt level in pool/spa. If salt level is too high, lower salt level by draining some of
the pool water out of the pool and replace with fresh water. Continue until the salt
concentration is at recommended levels.
6. “Check Cell” LED flashing
Inspect and clean cell according to directions. When done, press the “diagnostic” button
for 3 seconds to stop the “Inspect Cell” LED flashing.
7. “Check Cell” LED illuminated
Remove and inspect the cell for scale. 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

BLSC switch in OFF position.

Desired Level% adjustment setting is too low.

Low stabilizer (Cyanuric Acid).Chlorine is being produced but the pool water is
unable to hold on to the chlorine, due to low stabilizer.

Filter pump switched off or filter pump time too short (8 hours for average size
pools, more for large pools).

Salt level too low (below 2500 ppm, Low Salt LED on).

Salt level too high (high Salt LED on).

Low pH. Low pH oxidizes chlorine quickly, making it difficult to maintain desired
chlorine levels. Adjust pH levels to re-balance water.

Warm pool water increases chlorine demand
—increase Desired Level% or
filter run time.

Cold water (below 50F) can cause BLSC 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
