Installation
AAON equipment has been designed for
quick and easy installation.
Locating Unit
CC Series units are designed for outdoor
application and placement at ground level or
on a rooftop. Units must be placed on a level
and solid foundation that can support the
unit’s weight.
When rooftop mounted, a steel frame must
be provided that will support the unit above
the roof itself for load distribution.
When installed at ground level, a one-piece
concrete slab - preferably at least 4 inches
thick - should be used with footings that
extend below the frost line (a substantial
base that will not settle). Slab should be
surrounded by a graveled area for proper
drainage and should not adjoin the building
as sound and vibration may be transmitted to
the structure. Care must also be taken to
protect the coils and fins from damage due
to vandalism or other hazards.

Air flow to and from the unit must not be
restricted. Coils and fans must be free of any
obstructions and debris in order to start and
operate properly with a correct amount of
airflow. Obstruction to airflow will result in
decreased performance and efficiency.
6-63 ton units are vertical air discharge and
should not be installed in an enclosure or pit
that is deeper than the height of the unit. If
recessed installation is necessary, the
clearance to maintain proper air flow is at
least 6 feet. There must be no obstruction
above the equipment. Do not place the unit
under an overhang.
