Removing Supply and Exhaust Fan Shipping Channels (Motors >5Hp)

Each supply fan assembly and exhaust fan assembly for S_HF units shipped with a motor larger than 5 HP is equipped with rubber isolators, (as standard), or optional spring isolators. Each supply fan assembly and exhaust fan assembly for S_HG units is equipped with spring isolators. Shipping channels are installed beneath each fan assembly and must be removed. To locate and remove these chan- nels, refer to Figure 3-8 and use the following procedures.

Rubber Isolators:

1.Remove and discard the shipping bolts from the fan as- sembly rails.

2.Elevate the fan-and-motor assembly and slide the shipping channels out from between the fan assembly rails and the unit's base rail.

3.Lower the fan-and-motor assembly onto the isolators. Make sure that the pins at the top of the isolators are en- gaged in the corresponding holes on the fan assembly.

4.Verify that the fan assembly is being supported by the iso- lators.

Spring Isolators:

Spring isolators for the supply and/or exhaust fan are shipped with the isolator adjusting bolt backed out. Field adjustment is required for proper operation. Figure 3-8 shows isolator locations. To adjust the spring isolators use the following procedure.

1.Remove and discard the shipping tie down bolts but leave the shipping channels in place during the adjust- ment procedure. See Figure 3-8.

2.Tighten the leveling bolt on each isolator until the fan assembly is approximately 1/4" above each shipping channel.

3.Secure the lock nut on each isolator.

4.Remove the shipping channels and discard.
