Changing the Filter

When the filter exceeds 2800 hours (approximately 4 to 6 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.
