Suspended Fans

This is the most common method of installation. Fans mounted in ductwork are usually are

suspended from the ceiling using threaded rod and either spring or rubber in shear ceiling

isolators.

• Attach threaded rod to the support structure directly over the fan mounting

holes.

• Raise the fan up to the installation location and temporarily support it in place.

• Attach the isolators to the ends of the threaded rod

• Attach the other end of the isolator brackets to the support clips (vertical or

horizontal)

• Using an adjusting nut, on the threaded rod, adjust until all the isolators bear

the weight uniformly.

• Secure firmly using a locking nut

• Remove the temporary fan supports

• Attach the duct to it’s flanges

• Drill holes in the duct flanges to match the fan flanges and bolt together (use

flexible connection to connect fan to ductwork). NOTE: never support the

ductwork from the fan as the isolators have been sized to support the fan

weight only.

OPERATION

Pre Start Inspection

• Lock out all power sources

• Inspect all fasteners and set screws and tighten as required to the proper

torque settings (see chart)

• Inspect belt alignment and tension

• Confirm power source voltage and motor voltage are the same and that the

motor is wired correctly

• Rotate the fan blade to ensure that neither the fan blade nor the belts come

into contact with the housing

• Inspect the fan and the ductwork to ensure they are free of debris

• Check to ensure that all guards and accessories are securely mounted

• Check to be sure the propeller rotation is correct
