Honeywell F58F Owner's Manual - Page 10

If your air cleaner has a W8600F Air Cleaner Monitor, the SERVICE indicator will activate when it is time to wash the cells and prefilters. Wash them following the instructions starting on page 9. To turn the SERVICE indicator off, press the reset button on the lower right of the W8600F (see picture below). You may consider washing your cells and prefilters before the SERVICE indicator activates if some activity in your home has changed. This can include, but is not limited to the following: • Have the windows been open more often? • Has someone been smoking more often? • Has someone taken up a dust producing hobby? If this activity change is permanent, you may want your installer to change the WASH schedule that was entered into the W8600F when it was installed.
