Changing the
HEPAtech
®
Main Filter
When the
HEPAtech
®
Main Filter exceeds 2800 hours (approximately 4 to 6 months of use),
the
HEPAtech
®
Main Filter Indicator will turn on as a reminder that you should replace the
filter. Refer to Filter Life Counters for additional information, pg. 9. This is a reminder that
you should check the filter and replace it if necessary. The proper time to change the filter
depends on usage and the environment. Generally, 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 under the Grill Release Handle
and pull up. Refer to Figs. 4 and 5 (pg. 6).
3. Lift the Filter Tab and gently pull the filter out of the unit. Refer to Fig. 6. While
removing the filter, note the filter’s orientation - the new filter will be installed
with the same orientation. Refer to Fig. 10. Once removed, the used filter can be
discarded. While removing the filter, note the directional arrows printed on the top
of the filter. The filter will be reinstalled with the same orientation. Refer to Fig.
12.
