Fan Modules; Fan Isolation; Removing Shipping Tie-Downs - Trane Climate Changer M Series Installation Operation & Maintenance

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:
