When the system begins to backwash, the display will change to indicate the cycle of the backwash pro-
cess (see Table 3) 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 backwash is completed.
Manual Backwash
Sometimes there is a need to backwash the system sooner than when the system calls for it, usually
referred to as a manual backwash. There may be a period of heavy water usage because of guests or a
heavy laundry day.
To initiate a manual backwash at the preset delayed backwash time, simultaneously press UP + DOWN
buttons together and release. The arrow will point to the word Regen if a regeneration is expected
“tonight.” To cancel the backwash simultaneously press UP + DOWN buttons and release.
To initiate a manual backwash immediately, simultaneously press UP + DOWN buttons together for three
seconds. The system will begin to backwash immediately. The request cannot be cancelled.
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
backwashing, the cycle picks up where it was interrupted when the power returns.
An arrow will point
to the word Regen
if a regeneration is
expected “tonight.”
