ENGLISH
Corrective Action
Verify chlorine was not manually added.
Verify the saltwater chlorinator powerpack
and cell work properly.
Check for proper valve positions and leaks
in chlorine lines.
Check circuit breaker.
Check flow through flow cell and controller.

disabled if the green flow LED is not
illuminated.
Refill the feeder
Increase pH dose time (seconds)
Calibrate, clean or replace pH sensor
Check and adjust alkalinity
Repair the feed pump
Check the saltwater chlorinator and its cell
Increase overfeed alert time
Calibrate, clean or replace the ORP sensor
Lower cyanuric acid concentration in the pool
Increase daily filtration time
