4. Cleaning the Air Quality Sensor
a. As you are facing the unit, locate the Air Quality Sensor
on the left side. Open the cover by pulling down on the
indentation at the top and lowering it to a 90° angle.
The cover is not removable, and will stay in place while
opened.
b. Clean the Air Quality Sensor Cover with a soft brush or
cloth. You can also use a vacuum cleaner if desired.
c. Using the diagram to the right as a guide, lightly
moisten a cotton swab and clean the Lens (a), Air Inlet
(b), and Air Outlet (c). Wipe off all moisture with a dry
cotton swab.
NOTE: Without regular cleaning, the Air Quality
Sensor’s performance will deteriorate.
In areas with a higher concentration of pollutants, clean
the Air Quality Sensor more often.
