5 Operating Your Air Purifier Ionizer: Press this button to turn 'on' the ionizer. When the ionizer is 'on', the green light near the button will be illuminated. On/Speed Control: Rotate the Speed Control knob to set the desired speed. A setting of zero (0) indicates that the unit is off, one (1) is low speed, two (2) is medium speed, and three (3) is high speed. The fan speed can be adjusted at any time. Filter Change Calendar: The filter counter is designed to optimize the performance of the air purifer by reminding you when to change the HEPAtech Filter and pre-filter. HEPAtech Filter Calendar: The HEPAtech Filter indicator is located at the top of the calendar ring. To set the HEPAtech Filter counter, rotate the calendar ring to align the month that you installed the filter with the top indicator. Since the filter is designed for 6 months use, the two indicators will serve as reminders to change the filter every 6 months. Pre-filter Calendar: The inner knob of the filter counter is the pre-filter counter. To use, align the knob with the month that you installed the pre-filter. Figure 3 - Calendar Knob The replace symbol on the inner knob points to the month in which you should install a new pre-filter. The pre-filter is designed for three months of usage. Cleaning And Filter Replacement 1. Clean the outside of the unit with a soft, damp cloth. The front grill can be removed and cleaned in soapy water. 2. At least every 90 days, open the front grill, remove the carbon pre-filter, and replace it. This is necessary to maintain proper odor-removing and overall filtration performance. If necessary, it can be changed more often. Mark the new filter installation sticker included with the new carbon pre-filter. Be sure to remove any plastic wrapping that may be on the new filter before you place it into the Air Purifier. 3. While replacing the pre-filter, you should view the condition of the HEPAtech Filter. Compare the filter to the color coded chart that is on the inside of the housing. If the filter matches the dark color on the chart, you should remove the filter and replace it with a new filter. Be sure to remove any plastic wrapping that may be on the new filter before you place it into the Air Purifier. © 2007 Hunter Fan Company 41663-01 10/24/2007
