7.2.2 FILTER LIMIT
This general rule will provide you with a good
estimate of your filter’s life in hours. Assume
that the fan will run at 1/3 duty cycle or 8 hours
per day. Common 90-day filters are then good
for 90*24/3=720 hours of use. This is the
default limit value. Setting the filter counter limit
to 0000 will disable the change filter indicator.
Valid entries are from 0 to 2000 hours.
To set the number of hours of filter use before
replacement is indicated:
• Rotate the dial to the
AIR FILTER
position. The
current filter usage will be shown with
HRS
FILTER
.
• Hold
NEXT
for 2 seconds. The Filter limit will
be displayed.
• Refer to your Air Filter package to determine
your filter’s recommended life. If given in days,
multiply by 8 to find the recommended setting in
hours of filter usage.
