Cleaning the Air Quality Sensor
On models equipped with the Air
Quality Sensor, it is recommended to
clean the sensor monthly.
1.
Remove the air sensor cleaner from
the storage compartment behind the
sensor door.
2.
The sensor is located on the side of
the unit. Open
the sensor
compartment
(as illustrated),
then place
the air sensor
cleaner into
the sensor
opening.
3.
Push the air sensor cleaner in and
out of the sensor opening several
times to clean the sensor lens.
4.
Close the sensor compartment and
put the air sensor cleaner back in the
storage compartment. Make sure the
sensor door is fully closed. If it is not,
the sensor may not operate properly.

* Each air purifier is designed to filter
the room five times per hour at high
speed. Factors such as room shape
and ceiling height can affect this
rate. It is normal that the air flow will
be reduced as the filter becomes
clogged. Replace the HEPA filter as
needed.
