5©2010 Hunter Fan Co. 42018-01 20100609
CHANGING THE HEPA FILTER
When the filter exceeds 8000 hours
(approximately 1 year of use), the Filter Life
Counter will display 0% life remaining and the
Filter indicator will flash. This is a reminder
that you should check the filter and replace
if necessary. The proper time to change the
filter depends on usage and the environment.
Use the following list to help determine if the
filter should be changed:
• Compare the color of the filter to the color
coded chart on the inside of the housing. If
the filter color matches the darkest color on
the chart, you should replace the filter.
• If you notice a decrease in air output or
an increase in noise at any time during
normal operation, the filter may be clogged.
Replace the filter to return to normal
operation.
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 in the recesses on either side of the
top of the grill and pull firmly.
3. Gently pull on the filter to remove it from
the unit. While removing the filter, note the
directional arrows printed on the side of the
filter. The new filter will be installed with the
same orientation. Once removed, the used
filter can be discarded.
4. Remove the new filter from its wrapping
and look at the directional arrows printed
on the side of the filter. Install the filter with
arrows pointing towards the unit. 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. Reinstall the grill by first lining up the tabs
on the bottom of the grill with the openings
on the air purifier base and then pushing
the top of the grill forward until it is closed.
CHANGING THE PREFILTER
When the Pre-Filter exceeds 2000 hours
(refer to Filter Life Counters for additional
information), the Pre-Filter Life Counter will
display 0% life remaining and the Pre-Filter
indicator will flash as a reminder that you
should replace the pre-filter. To maintain
proper odor-removing capability and overall
filtration performance, the pre-filter should be
changed every 2000 hours (approximately 3
months of use). If necessary, the pre-filter can
be changed more often. Proper maintenance
of the pre-filter will help extend the life of the
HEPA filter.
1. First, turn off and unplug the air purifier.
2. Next, remove the front grill. Place your
fingers in the recesses on either side of the
top of the grill and pull firmly.
3. The pre-filter is attached to the inside of the
grill with hook tape. Pull gently on the pre-
filter to remove it.
4. If needed, use a soft damp cloth to wipe off
the grill.
5. Install the new pre-filter by placing it in the
grill and pressing gently on the pre-filter so
that it adheres to the hook tape. You may
notice a few black particles coming off the
pre-filter. Those particles are part of the
odor-removing activated carbon and will be
collected on the filter during regular use.
6. Install the grill back onto the unit. First, line
up the tabs on the bottom of the grill with
the openings on the purifier base and then
push the top of the grill forward until it is
closed.
7. Plug in the air purifier.
NOTE: This unit will not operate unless the
grill is in the correct position.
