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.
