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 f ilt ers before occupants t ake ownership of a

new home!

UPRIGHT INSTALLATIONS

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.
