Changing the Interval Setting
Resetting the Timer Program
During the normal operation, the system will flush
according to the set interval. It is possible the system
will flush at a time of high water use. If this poses a
problem, the controller can be reset. Unplug the power
supply, wait for 5 seconds, and then plug the power
supply in. When power is restored to the controller, it
will automatically enter Flush Mode. The controller will
then begin timing from the point when power is restored
based on the interval setting selected.

CAUTION
Changing the flush interval can cause the Ultra

of the filter. Consult the factory for more informa-
tion.

changed, use the chart below. Press and hold the cor-
responding button. After 5 seconds, the Button LED will
