Air Purifier Maintenance
To change the filter and reset the Filter Life Counter:
1. First, turn off and unplug the air purifier.
2. Next, remove the front grill. Place your fingers under the handle on the grill
and pull forward, then up. Refer to Figs. 4 and 5 (pg. 6).
3. Gently pull on the filter to remove it from the unit. While removing the filter,
note the directional arrows printed on the top of the filter. The new filter will
be installed with the same orientation. Refer to Fig. 10. Once removed, the
used filter can be discarded.
4. Look at the directional arrows printed on the side of the filter. Install the filter
with arrows pointing towards the unit. Refer to Fig. 10. Press the filter firmly
into the air purifier. To avoid damaging the filter media, you should press on
the frame of the filter only.
5. Place the front grill back onto the unit. First, line up the tab on the bottom
of the grill with the recess on the purifier base and then push the top of the
grill forward until it is closed. Refer to Figs. 6 and 7, pg. 7. NOTE: This unit will
not operate unless the grill is in the correct position.
6. Plug in the unit.
7. To reset the counter to zero hours and turn off the indicator, simply press
and hold the FILTER RESET key for three seconds. Then, you must release the
reset key and then press and hold the filter reset key again for three seconds
to turn off the filter indicator.
