shaft, motor, or tiers.
Storage
If the fan is stored for any length of time prior to installa-
tion, completely fill the bearings with grease or moisture-
inhibiting oil (refer to Lubricants on page 5). Rotate the
wheel several revolutions every three to five days to keep a
coating of grease on all internal bearing parts.
Store the fan in its original crate and protect it from dust,
debris and the weather.
Installation
Motor Installation
Most motors are shipped on the fans with belts and drives
installed. However, extremely heavy motors and drives are
shipped separately. These motors and drives will require
field installation. Please refer to page 4.
Duct Installation
Efficient fan performance relies on the proper installation
of inlet and discharge ducts. Be sure your fan conforms to
the following guidelines.
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.
