HAZARD
Failure to follow this warning could result in fire, personal
injury, or death.
Never operate furnace without a filter or with filter access
door removed.
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).
