Safety: Programming changes can be made with the unit powered and in service.

Review clean settings: Enter the programming menu and check the 'clean' or 'iron' cycle frequency. Adjust according to your actual iron level and manufacturer recommendations.
Check usage-based triggers: Ensure the unit is set for demand regeneration if desired, and that the flow meter is functioning correctly.
Monitor salt usage: After adjusting, observe salt consumption and water quality over several weeks to confirm proper operation.
