performance and energy efficiency, change or clean your filter regularly.

display to remind you to clean or change your
system’s filter. FILTER will continue to flash until
the counter is set back to zero.

blink FILTER ,then show the Filter Monitor counter.
After 15 seconds, the display will return to normal
mode, or you can hit RETURN to exit immediately.
The Filter Monitor will display up to 999 hours and
59 minutes of usage.
In this example, the counter is at 410 Hours,
26 minutes.
■ To reset the Filter Monitor counter, depress FILTER
for 3 seconds. The display will blink, and the counter
will be reset to zero.
