Receiving and Inspection
Immediately upon receipt of an AC fan,
carefully inspect the fan and accessories for
damage and shortage.
• Turn the wheel by hand to ensure it
turns freely and does not bind.
• Record on the Delivery Receipt any visi-
ble sign of damage.
Handling
Lift the fan by the shipping carton or lifting lugs provided
under top cap. NOTICE! Never lift by the shaft, motor or
housing.
Rotating Parts & Electrical Shock Hazard:
Disconnect electric power before working on unit.
Follow proper lockout / tagout procedures to ensure
the unit cannot be energized while being installed or
serviced.
A disconnect switch should be placed near the fan in
order that the power can be swiftly cut off, in case of
an emergency and in order that maintenance
personnel are provided complete control of the power
source.
Grounding is required. All field-installed wiring must
be completed by qualified personnel. All field-
installed wiring must comply with National Electric
Code (NFPA 70) and all applicable local codes.
Failure to follow these instructions could result in
death or serious injury.

Storage
If the fan is stored for any length of time prior to instal-
lation, store it in its original shipping crate and protect it
from dust, debris and the weather.
Damper
Use of any backdraft dampers is NOT permitted. Fire
dampers and/or smoke dampers may be required in a
smoke control system. These dampers must meet the
requirements determined by the local code authority.
Installation
If the fan was delivered with the motor unmounted, see
the maintenance section for belt and pulley installation.
Wiring
NOTICE! All wiring should be in accordance
with local ordinances and the National
Electrical Code, NFPA 70. Ensure the power
supply (voltage, frequency, and current
carrying capacity of wires) is in accordance
with the motor nameplate.
(See nextpage for diagram)
The attachment of roof mounted fans to the roof
curb as well as the attachment of roof curbs to the
building structure must exceed the structural
requirements based on the environmental loading
derived from the applicable building code for the
site. The local code official may require variations
from the recognized code based on local data. The
licensed engineer of record will be responsible for
prescribing the correct attachment based on
construction materials, code requirements and
environmental effects specific to the installation.
Failure to follow these instructions could result in
death or serious injury.
