and component parts. Units specified on a single order are
shipped with most components assembled in the specified airflow
direction. When an upper component exceeds the 108-in. maxi-
mum height limit, it is shipped out of its operating position. Some
component parts also require assembly or adjustment; see the sec-
tion on each component type for specific instructions.
CAUTION
Failure to assemble the units according to the procedures
set forth below is considered improper installation and
abuse and may not only negatively impact the weathertight
performance of the unit, but may also negatively affect the
Carrier warranty.
