Mounting the Motor Unit
1.
Use a Phillips screwdriver to loosen the (3) #8-32
screws about the center of the cover. Do not remove
the screws completely as they are captured on the
cover with plastic lock washers.
2.
Remove the bottom cover from the fan, ensure the
screws are still captured on the cover with the (3)
lock washers. Set the bottom cover to one side.
3.
Raise the fan and carefully guide
the motor shaft into the
extension tube. Feed the safety
cable and motor cable through
the motor.
4.
Bolt the fan motor shaft to the
extension tube. If Guy Wires are
to be used (on UMH and steel
extension), then fasten the Guy
Wire mounting brackets at this
location.
5.
Be careful of the wires in the
motor shaft and extension tube.
6.
Tighten the bolts to 30 ft-lbs [41 N-m] using torque and combination wrenches.
