Installation
AAON equipment has been designed for
quick and easy installation.
Lifting the Unit
CB Series condensing units have channels
underneath the base which provide lifting
access to the underside of the equipment and
allow moving and placement without
physical damage.
Figure 1 – Forklift Channels & Access Panel
Dollies and/or carts are recommended to lift
and place the unit to prevent damage to the
equipment and injury to the installer.
Care should be taken if using spreader bars,
blocking, or other lifting devices to prevent
any damage to the cabinet, coil or
condensing fans.
Before lifting unit, be sure that all shipping
material has been removed from unit.
Hoist unit to a point directly above the
condenser pad, and lower unit into the
proper place. Unit may also be positioned
with a dolly. When the unit is in place,
remove the dolly or lifting device. Make
sure the unit is properly seated and level.
Locating Unit
CB Series condensing 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 or composite condenser pad
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.
Airflow to and from the condensing 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 air
flow will result in decreased performance
and efficiency.
The installation position must provide at
least one foot of clearance from the wall for
proper air flow to the coils. When multiple
units are mounted adjacent to each other, the
clearance required between them is three
feet.
Service compartment must be accessible for
periodic servicing of controls, safety
devices, and refrigerant service/shutoff
valves. At least two feet of clearance on this
Incorrect lifting can cause damage to
the unit.
