Installation
Move the fan to the desired location. Check and
tighten fasteners throughout the unit and then fasten
securely through mounting holes provided in the base
angles. The unit must be set level (shimming may be
necessary). Flexible duct connections and vibration
isolators should be used where noise is a factor.
The motor voltage and ampere rating must be
checked for compatibility with the electrical supply
prior to final electrical connection. Supply wiring to the
fan must be properly fused, and conform to local and
national electrical codes.
The discharge is factory set as specified by customer
order, however, certain sizes can be rotated to
other discharge positions in the field if necessary.
If rotating the fan housing, accommodations may
need to be made for the fan to drain properly. The
USF-200, all sizes and USF-300, sizes 24 and less,
have field rotatable housings. For the USF-400 and
CSW, rotatable housings are standard sizes 30 and
less, arrangements 1, 9 and 10, and Class 0, I and II.
Class III and IV are not field rotatable. Removal of the
housing bolts allows the discharge to be rotated to the
clockwise positions above. For DB discharge position,
a portion of the frame angle must be removed.
Fan rotation is always specified from the drive side of
the housing.

Fans – Rigging and Lifting
Fans are to be rigged and moved by the lifting
brackets 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.
• ALL lifting brackets on each component must be
utilized at the same time.
• Fan to be kept level during lifting and installation.
Shading indicates lifting point locations
CAUTION
Fans should never be lifted by the shaft, motor,
motor cover or accessories.
