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 1400 hours HEPAtech® Filter 2800 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 Pre- Filter 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. 41599-01 8 41599-01_05.03.06.pmd 8 5/3/06, 10:42 AM Programming Locking/Unlocking the Keypad Once you enter the desired speed, you may want to lock the keypad to prevent accidental changing of the speed.

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 Changing the Filter (pgs. 10 and 11) to determine when and how to replace 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. 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 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 HEPAtech® filter. Refer to Obtaining Replacement Filters (pg. 12) 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 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 prefilter 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. 41599-01 10 41599-01_05.03.06.pmd 10 5/3/06, 10:42 AM Air Purifier Maintenance 6.
