®
Installation
Inspect the unit for any damage and report it to
the shipper immediately. Also, check to see that all
accessory items are accounted for.
Move the fan to the desired location and 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, it can be rotated to other discharge
positions in the field if necessary. Removal of the
housing bolts allows the discharge to be rotated to
the clockwise positions below. For TAD, BD and BAD
discharge positions, a portion of the frame angle must
be removed.
Clockwise rotation shown. Counterclockwise
discharge positions are a mirror image of those
shown. Fan rotation is always specified from the drive
side of the housing.
