Receiving and Inspection
Carefully inspect the fan and accessories for any
damage and shortage immediately upon receipt of the fan.
• Turn the propeller by hand to ensure it turns freely and
does not bind.
• Check dampers (if included) for free operation of all
moving parts.
• Record on the Delivery Receipt any visible sign of
damage.
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.

Handling
Lift the fan by the base or by the shipping carton.
NOTICE! Never lift by the shaft, motor or housing.
NOTICE! If your fan has a special protective finish,
handle with extreme care. Even a small chip will break the
coating’s continuity and destroy its ability to protect the
metal.
Propellers are carefully balanced to give smooth,
vibration-free operation. If the propeller is damaged during
handling, it will require rebalancing.
Storage
If the fan is stored for any length of time prior to
installation, store it in its original shipping crate and protect
it from dust, debris and the weather.
Outdoor Storage
To maintain good working condition of the fan when it is
stored outdoors or at a construction site, follow the
instructions below.
• Coat the shaft and bearings with grease or rust
preventative compound to help seal out moisture.
• Periodically rotate the propeller and operate the
dampers (if supplied) to keep a coating of grease on all
internal bearing parts.
• Periodically inspect the fan to prevent damaging
conditions.
• Block propeller to prevent natural rotation.
• Cover the unit with some type of weather cover to
prevent moisture, corrosion, dirt or dust accumulation.
