Power Loss
If the power goes out, current time of day will need to be reset. If the power goes out while the
system is regenerating, the cycle picks up where it was when the power went out.
Error Message
If “E1” “E2” or “E3” appears on the display, contact CUNO Water Treatment Technical Support
Services @1-866-692-2543. These are error codes and will need to be resolved before the control
valve will function. These codes indicate that the control valve did not function properly.

General Operation
When the system is operating, one of two displays will be shown. Pressing
or button will
alternate between the displays. One of the displays is always the current time of day (to the nearest
hour). The second display is the days remaining until the next regeneration. If the days remaining
is equal to one, a regeneration will occur at the next preset regeneration time. The user can scroll
between displays as desired.
If the system has called for a regeneration that will occur at the preset time of regeneration, the
arrow will point to Regen.
Regeneration Mode
Typically system is set to regenerate at a time of low water usage. Your Chem-Free Iron Reduction
System is factory preset to regenerate at 1:00 AM. If there is a demand for water during the regenera-
tion period, untreated water will be used.
When the system begins to regenerate, the display will change to indicate the cycle of the regeneration
process that is occurring and an arrow will also point to REGEN. The system will run through the
steps automatically and will reset itself to provide treated water when the regeneration is completed.
