Component Installation Requirements
Fan Modules
The fan module can be configured as either draw-thru or blow-thru. Review the submittals and unit
tagging information prior to assembly to determine placement.
Fan Isolation
The fan-and-motor assembly is internally isolated. The fan and motor bases are bolted to a
minimum of four spring isolators. The isolators are secured to the fan module support base.
Shipping tie-down bolts are bolted adjacent to the isolators between the fan isolation base and the
isolator support frame. The shipping tie-downs secure the isolation base to the support assembly
to prevent any damage to the fan module during shipment.
Note:
Remove the tie-downs only if the factory-provided isolation is to be used.
Removing Shipping Tie-Downs
There are three types of shipping tie-downs used to secure the isolation base, depending on unit
size:
•
Sizes 3 to 8 use a 3/8 x 1-inch pipe (see
Figure 32
).
•
Sizes 10 to 57, use a tie-down bolt and shim (see
Figure 32
).
•
Sizes 66 to 120 and plenum fans use a tie-down angle and bolt (see
Figure 33
).
