™
5. AirSmart Display – When the air
purifier is first turned on, the
™
AirSmart sensor will analyze the air
to determine the current air quality.
A bar will move back and forth
across the display panel until the air
quality is determined. This will take
about one minute. The sensor will
then continue to monitor and show
the air quality (poor, fair, or good) in
a bar graph in the display. If the fan
is set to Auto, the sensor automati-
cally adjusts the fan speed for the
most effective air purification.

sary, replaced, press the recessed
RESET button with the end of a pen,
toothpick, or small nail. This will
reset the "timer-like" control.
