dling, it will require rebalancing.
Storage
If the fan is stored for any length of time prior to installa-
tion, 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 addi-
tional instructions below.
• Coat the shaft and bearings with grease or rust preven-
tative compound to help seal out moisture.
• Periodically rotate the propeller and operate the damp-
ers (if supplied) to keep a coating of grease on all inter-
nal bearing parts.
• Periodically inspect the fan to prevent damaging condi-
tions.
• Block propeller to prevent natural rotation.
• Cover the unit with some type of weather cover to pre-
vent moisture, corrosion, dirt or dust accumulation.

Disconnect switches are recommended. Place
the disconnect switch near the fan in order that
the power can be swiftly cut off in case of an
