Introduction
Thank you for purchasing the QuietFlo
Ultra Ionizing HEPA Air Purifier from Hunter Fan
Company. You have purchased our latest development in portable air purification which has been designed to improve the quality of the air that you breathe. The following innovative features are included in your Hunter Air Purifier.

High Particulate Efficiency: The HEPA filter will remove 99.97% of 0.7 micron particles from the air that passes through the filter.
Odor Removal: The activated carbon pre-filter helps remove odors such as cooking, smoke, and pet smells from the air. It also traps lint, hair, and other large particles to help extend the life and performance of the HEPA filter.
Ionizer: The ionizer improves the quality of air in the room by releasing negative ions into the air that attract positively charged dust, smoke, and pollen particles.
Quiet: The air purifier has been designed to operate quietly and efficiently. You can choose among three speeds to best meet your needs at different times.
Filter Counters: Filter maintenance is critical to the performance of the air purifier. To help you determine when to change the filters, the pre-filter and HEPA filter, the unit has built in life counters that keep track of the life remaining of each filter.
NiteGlo™ Light: Your air purifier display has a backlight that is continuously lit as long as there is power to the unit. You can choose to turn the backlight off or on.

How the QuietFlo ®Ultra Ionizing HEPA Air Purifier System Works
As the air is pulled into the purifier, the activated carbon pre-filter absorbs odors and catches large particles. Then, the air travels through the HEPA filter where the smaller particles are collected. Then, the ionizer releases negative ions into the air that attract positively charged dust, smoke, and pollen particles. Finally, the clean, purified air is released back into the room.

Operation

Initial Operation
This section provides basic instructions on the use of your air purifier. After following these initial directions, please continue reading this booklet to learn how to operate the more advanced features of your air purifier.
Basic Operation of the Air Purifier:

Take the air purifier out of the box and remove the clear plastic protective bag. Place the unit on a firm level floor.
Before turning on the air purifier, you need to confirm that the filters are firmly in place and have not become loose during shipping. To check the filters, first open the front grill. Release the front grill by placing your fingers under the handle on the grill and pull forward, then up. Refer to Figs. 4 and 5.
Next, check the HEPA filter by pressing firmly on all four corners of the filter to ensure that it is fully inserted into the filter opening.
The carbon pre-filter is mounted inside the front grill with hook tape. Confirm that it properly covers the grill vents. 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 use.
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. NOTE: This unit will not operate unless the grill is in the correct position.
Plug the unit into a 120V electrical outlet and press the OFF/SPEED key. The air purifier will start with a low blower speed.
Use the OFF/SPEED and TURBO keys to adjust the blower speed to the desired level (Off, Sleep, Active, Turbo Clean). Refer to Fig. 8.
Use the TURBO key to adjust the blower speed to high. After 1 ⁄2 hours, the fan will return to the previous speed setting.

Filter Life Counters
The pre-filter and filter are critical to the proper operation of the air purifier. To help you know when to change the filters, your Hunter Air Purifier has Filter Life Counters that will monitor the percentage of life your filter has left. Although the exact life of the filters depends on the environment, the table below gives typical usage times of the filters.
Table 2: Typical Usage Times of the Filters

Filter Type	Typical Usage
Activated Carbon Pre-Filter	2000 hours
HEPA Filter	8000 hours

The display shows the percentage of life left since the counter was reset.
NOTE: The percentage level drops in 5% increments.
The values of the Pre-Filter and Filter Life Counters are stored in the air purifier’s memory. The unit may be unplugged and moved or stored without losing the PreFilter and Filter Counter values.
To properly track filter usage, the Pre-Filter and Filter Life Counters should be reset each time the filters are changed. Refer to Changing the Pre-Filter (pg. 10) or Changing the Filter (pg. 11) for instructions on how to reset the counters.
Locking/Unlocking the Keypad
Once you enter the desired speed, you may want to lock the keypad to prevent accidental changing of the speed. When the keypad is locked, all keys will be disabled. If you press a key, the Keypad Locked Indicator will be displayed on the screen for 1-2 seconds.
To Lock or Unlock the Keypad:
To Lock or Unlock the Keypad:

To lock the keypad, press and hold the OFF/SPEED and TURBO keys simultaneously for 2-3 seconds. The Keypad Locked Indicator will appear on the display. Refer to Fig. 9. After releasing the keys, the Keypad Locked Indicator will disappear.
To unlock the key pad, press and hold the OFF/SPPED and TURBO keys simultaneously for 2-3 seconds. The Keypad Indicator will disappear and the keypad will be functional.

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:

Unplug the unit for at least 30 seconds.
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 recommend that you place your air purifier six (6) inches away from any walls.
To turn the ionizer on or off:

To turn the ionizer on, press the IONIZER key. The Ion- izer Indicator will appear on the display. Refer to Fig 10.
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:0
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.

Air Purifier Maintenance

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:

Approximately every 90 days, the outside of the unit should be cleaned with a soft, damp cloth.
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.
Follow the instructions in Changing the Pre-Filter and Changing the Filter (pgs. 10 and 11) to determine when and how to replace the filters.

Changing the Pre-Filter
When the Pre-Filter exceeds 2000 hours (refer to Filter Life Counters for additional information, pg. 8), 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.
Refer to Obtaining Replacement Filters (pg. 13) if you need help finding replacement filters.
To change the pre-filter and reset the Pre-Filter Life Counter:

First, turn off and unplug the air purifier.
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).
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.
If needed, use a soft damp cloth to wipe off the grill.
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.
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.

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 (refer to Filter Life Counters for additional information, pg. 8). 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.
