Handling
Lift the fan by the lifting
lugs provided under top cap.
NOTICE! Never lift by the
shaft, motor or housing.
Storage
If the fan is stored for
any length of time prior to

original shipping crate and
protect it from dust, debris and
the weather.
Code Requirements & Environmental Effects:
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.
Installation
If the fan was delivered with the motor unmounted, see
the maintenance sections for belt and pulley installation.
Wall Exhausters
If the fan is a wall mount unit and a grease terminator
or grease trough was not purchased, a 1-1/16 inch
diameter drain hole should be inserted on the bottom side
of the unit for drainage.
