Filter Replacement Filter Replacement Indicator: Your Defender® is equipped with a Filter Replacement Indicator located on the front panel. Anytime this red indicator flashes, it is recommended that you call your authorized FILTERQUEEN® Distributor to order a replacement filter. Anytime this red indicator stops flashing and remains solidly illuminated, it is recommended that you change your filter. To receive full benefit from your Defender® and to extend your warranty, it is strongly recommended that you follow the filter replacement schedule suggested above. Under higher pollution levels, your filters will need to be replaced more frequently. The Filter Replacement Indicator is operated by filter time in use and is controlled by an onboard timer. After 11 months of time in use of your Medi-Filter® Cartridge, the Filter Replacement Indicator will begin to flash. It will continue to flash until the you reach 12 months of time in use, at which time the Filter Replacement Indicator will stop flashing and remain solidly illuminated. After replacement of your Medi-Filter® Cartridge, you must reset the Filter Replacement Indicator's timer. When the timer has been properly reset, the Filter Replacement Indicator will turn off. Resetting the Filter Replacement Indicator Timer: After replacement of your Medi-Filter® Cartridge per the instructions found on page 7, the Filter Replacement Indicator's timer can be reset by performing the following sequence of steps: 1Plug unit into outlet. 2Press power On/Off switch to the On ("I") position. 3Allow unit to start running at low speed. 4PRESS and HOLD both the Up and Down arrow buttons until the Filter Replacement Indicator starts to blink. 5 Release both the Up and Down arrow buttons. 6 While the Filter Replacement Indicator is still flashing*, again PRESS and HOLD both the Up and Down arrow buttons until the Filter Replacement Indicator turns off. If the steps above have been performed properly, the Filter Replacement Indicator will turn off and not flash again for 11 months. If the Filter Replacement Indicator remains on, repeat the steps again. *Note that in step 6 above, the Filter Replacement Indicator MUST still be flashing when the buttons are pressed the second time. The Filter Replacement Indicator will continue to flash for approximately 3 seconds after the buttons are released as required in step 5 above. Note: Under higher pollution levels, your filters will need to be replaced more frequently. Note: To order replacement filters, call your authorized FILTERQUEEN® Distributor, or call 1-440-846-7800 for the Distributor nearest you.
