external Filter'Media cabinet (if provided) or the furnace blower
compartment. Factory supplied washable filters are shipped in the
blower compartment.

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 lbr location and size of
