When the furnace is used in connection with a cooling unit, the
furnace should be installed in parallel with or on the upstream side
of the cooling unit to avoid condensation in the heating element.
With a parallel flow arrangement, the dampers or other means
used to control the flow of air must be adequate to prevent chilled
air from entering the furnace and, if manually operated, must be
equipped with means to prevent operation of either unit unless the
damper is in the full heat or cool position.
When the furnace is installed without a cooling coil, it is recom-
mended that a removable access panel be provided in the outlet
air duct.  This opening shall be accessible when the furnace is
installed and shall be of such a size that the heat exchanger can be
viewed for visual light inspection or such that a sampling probe can
be inserted into the airstream.  The access panel must be made to
prevent air leaks when the furnace is in operation.
When the furnace is heating, the temperature of the return air enter-
ing the furnace must be between 55°F and 100°F.

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 by the installer. Filters must comply with UL900
or CAN/ULCS111 standards. If the furnace is installed without fil-
ters, the warranty will be voided.
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
undersized opening will cause reduced airflow.
Refer to Minimum Filter Area tables to determine filter area require-
ments.

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.
