The return-air duct must be connected to return-air opening

furnace.
V. FILTER ARRANGEMENT
→
WARNING: Never operate unit without a filter or with
filter access door removed. Failure to follow this caution
will result in intermittent unit operation or performance
satisfaction.
The air filter arrangement will vary due to application, furnace
orientation, and filter type. The filter may be installed in an
external Filter/Media cabinet (if provided) or the furnace blower
compartment. Factory supplied washable filters are shipped in the
blower compartment.
If a factory-supplied external Filter/Media cabinet is provided,
instructions for its application, assembly, and installation are
packaged with the cabinet. The Filter/Media cabinet can be used
with the factory-supplied washable filter or a factory-specified
high-efficiency disposable filter (see cabinet instructions).
If installing the filter in the furnace blower compartment, deter-
mine location for filter and relocate filter retaining wire if
necessary. See Table 2 to determine correct filter size for desired
filter location. Table 2 indicates filter size, location, and quantity
shipped with this furnace. See Fig. 2 for location and size of
bottom and side return-air openings.

* Filters may be field modified by cutting filter material and support rods (3) in
filters. Alternate sizes and additional filters may be ordered from your dealer.
† Factory-provided with furnace.
CAUTION: Use care when cutting support rods in filters
to protect against flying pieces and sharp rod ends. Wear
safety glasses, gloves, and appropriate protective cloth-
ing. Failure to follow this caution could result in minor
personal injury.
CAUTION: For airflow requirements above 1800 CFM,
see Air Delivery table in Product Data literature for
specific use of single side inlets. The use of both side
inlets, a combination of 1 side and the bottom, or the
bottom only will ensure adequate return air openings for
airflow requirements above 1800 CFM. Failure to follow
this caution will result in intermittent unit operation or
performance satisfaction.
