filters can be inspected and cleaned or changed after dis-
connecting the electrical power and removing the optional
access door in the return air plenum. If the installation does
not have an access door proceed as follows:
1. Disconnect the electrical power.
2. Remove the upper door from the furnace.
3. Remove the left filter first by reaching to the left side of
the blower, pushing the filter up slightly to remove it from
the filter rack. Then carefully pull the filter down past the
left side of the blower housing. Be careful not to dis-
lodge any trapped dirt or debris from the filter (Figure 7).
4. Remove the right filter by reaching to the left side of the
blower. Lift filter up slightly to remove it from the filter
rack. Move the filter to the left side of the return air ple-
num, and down past the left side of the blower housing.
Be careful not to dislodge any trapped dirt or debris from
the filter (Figure 7).
a. Some installations will have two throwaway filters. If
dirty, these filters must be thrown away and replaced
with two new similar size throwaway filters.
b. Other installations will have two permanent filters.
Wash, rinse and dry dirty permanent filters. After
cleaning, both sides should be sprayed with a filter
adhesive (available in hardware stores) as instructed
on the adhesive container.
When badly torn or uncleanable, permanent filters
must be replaced with permanent filters of the same
type and size.
5. To reinstall the filters, first MAKE CERTAIN THE AIR-
FLOW DIRECTION ARROW POINTS TOWARDS THE
FURNACE. Then insert the filters from the left side of
the blower. Starting with the right filter, push the filter
into the plenum so that the bottom of the filter rests in
the filter rack and the upper edge rests against the side
of the plenum. Repeat with the left filter (Figure 7).
6. Replace the air circulation blower door, then reconnect
the electrical power.
Horizontal Filters (Not Included With Furnace)
For furnaces installed horizontally, filters must be installed
external to the furnace casing. A central return with filters
installed in the duct behind the return grille may be used.
This would simplify filter replacement by merely requiring
the removal of the grille. Clean or replace filters every two
months or sooner as required. Dirty filters are the most com-
mon cause of inadequate heating or cooling performance.
NOTE: If using Media Air Cleaner MAC1 or Electronic Air
Cleaner EAC5, follow the directions that came with the air
cleaner for proper filter removal, cleaning, and replacement
procedures.
