On upflow units, guide dimples locate the side return cutout
locations. Use a straight edge to scribe lines connecting the
dimples. Cut out the opening on these lines.
NOTE:
An under-
sized opening will cause reduced airflow.
Refer to the Filter Sizing Chart to determine filter area re-
quirements.
Change filters before occupants take ownership of a
new home!

NSTALLATIONS
Depending on the installation and/or customer preference,
differing filter arrangements can be applied. Filters can be
installed in the central return register or a side panel exter-
nal filter rack kit (upflows). As an alternative a media air
filter or electronic air cleaner can be used as the requested
filter.
