FILTER CLEANING AND REPLACING
Use a vacuum cleaner to clean out the blower area and the
adjacent area of the return air duct.
Wash, rinse, and dry a permanent filter. Both sides of a
metal filter should be sprayed with a dust adhesive as
recommended on the adhesive container. Spray adhesives
for use with permanent metal filters can be found at some
hardware stores.
If permanent filters are badly torn or uncleanable, they must
be replaced with permanent filters of the same type and
size.
When replacing permanent filter used in side air return
applications, the filter must have dimensions of 16" x 25" x
1".
When replacing permanent filter used in bottom air return
applications replace with same size and type permanent
filter.
Reinstall filter by placing it into the furnace along the side of
the blower. Engage filter in top rail, move toward side of
furnace and drop it into the bottom rail. BE SURE AIRFLOW
DIRECTION ARROW POINTS TOWARDS THE BLOWER.
COUNTERFLOW FILTERS (GDC AND GCD)
This manual discusses the furnace mounted filter rack
which is shipped with the furnace. Other filter arrangements
could have been used.
Counterflow Furnace Mounted Filter Rack
Remember dirty filters are the most common cause of
inadequate heating or cooling performance.
The furnace-mounted filter rack includes a rack mounted
on the top of the furnace. Two filters fit into the rack and rest
against the sides of the return air plenum, forming a "V"
above the furnace. (Figure 14)
