Sizes 7 thru 30
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
XUEF(D)-100, XUEF-200, and XUEF-300, all sizes,
have field rotatable housings. For the XUEF-400,
rotatable housings are standard on sizes 30 and less,
arrangement 10, and Class 0, I and II. Removal of the
housing bolts allows the discharge to be rotated to the
clockwise positions shown above. For downblast (DB)
discharge position, a portion of the frame angle must
be removed.
Fan rotation is always specified from the drive side of
the housing.
Installations with inlet or discharge configurations
that deviate from this manual may result in reduced
fan performance. Restricted or unstable flow at the
fan inlet can cause pre-rotation of incoming air or
uneven loading of the fan wheel yielding large system
losses and increased sound levels. Free discharge
or turbulent flow in the discharge ductwork will also
result in system effect losses. Refer to the following
diagrams for the most efficient installation conditions.
