Air Purifier Maintenance
Resetting the Air Purifier
In the unusual situation that the unit or the display is exhibiting erratic behavior, you
may want to reset the air purifier. If you still have problems after resetting the air puri
-
fier, please contact Hunter for additional assistance (refer to Technical Assistance,
pg. 15).
To Reset the Air Purifier:
1. Unplug the unit for at least 30 seconds.
2. Plug the unit back in.
Using the Ionizer
Using the ionizer improves the quality of air in the room. Negative ions are released
into the air and positively charged dust, smoke, and pollen particles are attracted to
the negative ions. These particles settle out of the air and can be vacuumed up dur
-
ing normal cleaning. These particles are also more easily captured by the cleanable
filter as they pass through the PermaLife™ Cleanable Filtration System. To ensure
the best air circulation in the room, we recommend that you place your air purifier
six (6) inches away from any walls.
To turn the ionizer on or off:
1. To turn the ionizer on, press the IONIzER
key. The
Ionizer Indicator will appear on the display. Refer to
Fig 10.
2. To turn the ionizer off, press the IONIzER
key. The
Ionizer Indicator will disappear.
Controlling the Backlight
Your air purifier display has a backlight that is continuously lit as long as there is
power to the unit. The backlight may be turned off.
To turn the backlight off or on:
Press the PRE-FILTER RESET and FILTER RESET keys at the same
time.
NOTE: Do not hold down the keys for longer than 2 seconds. This may
reset a filter counter.

Cleaning Your Air Purifier
Proper maintenance of your Hunter Air Purifier will help ensure years of trouble free
service.
Follow these steps to properly maintain your air purifier:
1. Approximately every 90 days, the outside of the unit should be cleaned with a
soft, damp cloth.
2. If needed, the front grill can be removed from the unit and cleaned with soapy
water. Simply remove the pre-filter before exposing the grill to water.
3. Follow the instructions in Changing the Pre-Filter and Cleaning the Filter (pgs.
11 and 12) to determine when and how to replace or clean the filters.
NOTES:
• The air purifier must be unplugged during the cleaning process.
• Be sure the unit is completely dry before plugging in and using.
• Never immerse unit in water.
Changing the Pre-Filter
When the Pre-Filter exceeds 1400 hours (refer to Filter Life Counters for additional
information, pg. 9), 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 1400 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 cleanable filter. Refer to Obtaining Replacement
Filters (pg. 14) if you need help finding replacement filters.
To change the pre-filter and reset the Pre-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. The pre-filter is attached to the inside of the grill with hook tape. Pull gently
on the pre-filter to remove it. Refer to Fig. 11 (pg 12).
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.
