IR UCT WORK
Filters must be used with this furnace. Discuss filter maintenance
with the building owner. Filters do not ship with this furnace, but
must be provided, sized and installed externally by the installer.
Filters must comply with UL900 or CAN/ULCS111 standards. If
the furnace is installed without filters, the warranty will be voided.
On upflow units, guide dimples locate the side return cutout loca-
tions. Use a straight edge to scribe lines connecting the dimples.
Cut out the opening on these lines. NOTE: An undersized open-
ing will cause reduced airflow.
Refer to Minimum Filter Area tables to determine filter area re-
quirements.

PRIGHT NSTALLATIONS
Depending on the installation and/or customer preference, differ-
ing filter arrangements can be applied. Filters can be installed in
the central return register or a side panel external filter rack kit
(upflows). As an alternative a media air filter or electronic air
cleaner can be used as the requested filter.
The following figure shows possible filter locations.
