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 purifier, please
contact Hunter for additional assistance (refer to Technical Assistance, pg. 14).
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 during normal cleaning.
These particles are also more easily captured by the HEPA filter as they pass through the
HEPA Air Purification System. To ensure the best air circulation in the room, we recom-
mend 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 Ion-
izer Indicator will appear on the display. Refer to Fig 10.
2. To turn the ionizer off, press the IONIZER key. The Ion-
izer 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.
