Display Modes
Your air purifier has 3 display modes – Clock Display, Pre-Filter Display, and Filter Dis-
play. When the unit is running, the display also provides additional information about the
settings of the air purifier. The features for each mode and how to change modes is de-
scribed below.
Clock Display: The default mode of the unit is the Clock Display.
In this mode, the day indicator, time, and AM/PM indicator will be
lit. If military time has been chosen (See Setting Day and Time, pg.
13), the AM/PM indicator will not be visible.
Pre-Filter Display: This display shows the number of hours that
the pre-filter has been in use. In addition to the run hours, you will
see the Pre-Filter indicator. If the run hours have reached 2000 hours
(approximately 3 months of use), the Pre-Filter indicator will flash
to show that the pre-filter should be changed. Refer to Filter Run-
Time Counters for additional information (pg. 12).
Filter Display: The Filter Display mode tells you how many hours
the filter has been in use. In addition to the run hours, you will see
the Filter indicator. If the run-hours have reached 8000 hours (ap-
proximately 1 year of use), the Filter indicator will flash to remind
you to check the filter. Refer to Filter Run-Time Counters for more
details (pg. 12).
