Then, you must release the reset key and then press and hold the pre-filter reset key again for three seconds to turn off the filter indicator. Changing the Filter When the filter exceeds 8000 hours (approximately 12 months of use), the Filter indicator will turn on as a reminder that you should replace the filter. (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. 11 41781-01_rev 12.08.05B.pmd 11 Continued 41781-01 12/8/05, 10:46 AM
