A return air filter is not supplied with this furnace; however, there
must be a means of filtering all of the return air. The installer will
supply filter(s) at the time of installation.

Improper filter maintenance is the most common cause of inad-
equate heating or cooling performance. Filters should be cleaned
(permanent) or replaced (disposable) every two months or as re-
quired. When replacing a filter, it must be replaced with a filter of
the same type and size.
T
O PREVENT PROPERTY DAMAGE, PERSONAL INJURY OR DEATH DUE TO
ELECTRICAL SHOCK, DISCONNECT ELECTRICAL POWER TO THE FURNACE
BEFORE REMOVING THE FILTER OR PERFORMING ANY OTHER MAINTENANCE.
Become familiar with filter location and procedures for removal,
cleaning and replacing them. If help is needed, contact the in-
staller of the furnace or a qualified servicer.

Depending on the installation, differing filter arrangements can
be applied. Filters can be installed in either the central return
register or a side panel external filter rack (upflow only). A media
air filter or electronic air cleaner can be used as an alternate filter.
Follow the filter sizes given in the Recommended Minimum Filter
size table to ensure proper unit performance.
To remove filters from an external filter rack in an upright upflow
installation, follow the directions provided with external filter rack
kit. To remove internal filters see Internal Filter Removal section.
Internal filters are an accessory item and are not included with
your furnace. For further details, see your distributor.

A furnace mounted filter rack ordered from distributor.
NOTE: If using Media Air Cleaner or Electronic Air Cleaner, fol-
low the instructions that came with the air cleaner for proper filter
removal, cleaning, and replacement procedures.
The furnace-mounted filter rack is mounted on the top of the fur-
nace. Two filters fit into the rack and rest against the sides of the
return air plenum, forming a "V" above the furnace.
Inspect the filters frequently and clean or replace when neces-
sary. In some installations, the filters can be inspected only after
the electrical power is disconnected and the optional access door
in the return air plenum removed. If the access door is not present,
proceed as follows:
1. Disconnect the electrical power.
2. Remove the non-louvered door from the furnace.
3. Remove the left filter by reaching to the left side of the
blower, pushing the filter up slightly to remove it from the
filter rack, and pulling it down to the left of the blower and
out the blower door. Repeat with the right filter.
4. Inspect filter. If your dirty filter is the disposable type,
replace dirty with the same type and size filter. If your dirty
filter is a permanent metal filter, clean as follows:
• Wash, rinse, and dry the permanent filters. Both sides
should then be sprayed with a filter adhesive as is
recommended on the adhesive container. Many
hardware stores stock spray adhesives for use with
permanent filters.
• If badly torn or uncleanable, these filters must be
replaced by equal size permanent, high velocity filters.
Throwaway filters must not be used as replacement for
permanent filters. Under normal use, permanent filters
should last for several years.
5. To reinstall the filters, first MAKE CERTAIN THE AIRFLOW
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 33).
6. Replace the blower door, then reconnect the electrical
power.
