machinery, fans also create a dangerous suction at the
inlet. Special caution needs to be used when moving
around a fan, whether it is in operation or not. Before

and/or lifting points provided or by the skid when a
forklift is used. Location of brackets varies by model
and size. Handle in such a manner as to keep from
scratching or chipping the coating. Damaged finish may
reduce ability of fan to resist corrosion. See coating
repair section of this manual for details involving touch-
up of damaged surfaces.
• Use standard lifting and rigging practices.

utilized at the same time.

• Fan to be kept level during lifting and installation.
