Cleaning the ionization chamber cells is required every 3-6 weeks depending on water quality. Cleaning is very easy. Simply close the bypass, drain the chamber cell, remove the cell, clean & scrub, rinse and reinstall. A chamber cell maintenance activity can normally be done in less than 20 minutes. Chamber cell electrodes are consumables and will deplete over time. These should be replaced every 12-18 months depending on the water load and electrode depletion, to maintain performance.
