Installation, Operating and Maintenance Manual
Upon receiving the unit, check for any damage and report it immediately to the shipper. Also assure all accessory
items are accounted for.
To minimize installation time, most fans are shipped completely assembled. Due to shipping size limitations, hoods for larger
fans will be shipped in sections. For these fans the hood and fan components can be transported to the roof location
separately. Hood assembly should begin after the fan is attached to the roof curb. Hood assembly instructions are included
with the hood components.
Care must be taken not to bend or distort the fan panel or drive components during installation.

Access to the motor compartment
On fan sizes 18 to 48:
- Remove two fasteners shown in fig. 1.
Carefully swing the hood 180 degrees and let it rest on
the roof. If desired, the entire hood may be removed
by removing the two additional fasteners on the
opposite side of the fan.
Use caution when handling the hood in strong winds.
On fan sizes 36 to 60 access to the motor compartment can
also be made by either:
- Removing birdscreen or filters and standing
under the hood of large fans.
- Removing one interlocking hood end section of
smaller units

ELECTRICAL CONNECTIONS Before electrical connections are made, the supply voltage, phase and ampere capacity must be checked for compatibility with the fan motor. In addition, the supply wiring must be properly fused and conform to local and national electrical codes. If the electrical supply is to be routed to the fan from the interior of the building, it should pass through the conduit hole in the fan panel. - Page 3 BEARINGS (For belt drive fans only) Bearings are the most critical moving part of the fan and should be inspected at periodic intervals. Locking collars and set screws, in addition to fasteners attaching the bearings to the bearing plate, must be checked for tightness. In a clean environment and temperatures above 32°F./below 200°...
