Never operate unit without a filter or with the blower access
panel removed. Failure to follow this warning could result in
a fire, personal injury, death, or damage to furnace blower
motor. Dust and lint on internal parts in furnace can cause a
loss of efficiency.
NOTE: If the filter has an airflow direction arrow, the arrow must
point toward the blower.
To clean or replace filters, proceed as follows:
If filter is installed in filter cabinet adjacent to furnace:
1. Turn off electrical supply to furnace.
2. Remove filter cabinet door.
3. Slide filter out of cabinet.
4. If equipped with permanent, washable filter, clean filter by
spraying cold tap water through filter in opposite direction of
airflow. Rinse filter and let dry. Oiling or coating of the filter
is not recommended.

5. If equipped with factory specified disposable media filter,
replace only with a factory specified media filter of the same
size.
