Consistently Low Chlorine; Consistently High Chlorine - ControlOMatic MegaChlor Installation & Operation Manual

Consistently Low Chlorine

� Power level too low: Increase the power level.
� Low salt level: Adjust the salt level as necessary. The ChlorMaker will make less chlorine with a lower

Make sure you are measuring the chlorine at the end of a chlorine production cycle.
� Plates need cleaning: See above.
� High bather load: Additional chlorine or shock may be needed.

happens the ChlorMaker shuts down and will stop making chlorine to protect the power supply. Drain
out some of the water and refill with fresh water to lower the salt level. Cycle power or press the boost
button to start a production cycle to test again.
� Just doesn't keep up:
� Remove organic material such as leaves and clean the filter.
Make sure the cell is at the deepest point in the spa and in a VERTICAL ORIENTATION!

makes chlorine slowly and removing the phosphates will help lower the spas chlorine consumption
demand.
� Shock the water: You can use either a chlorine based shock or chlorine free.
