lift the motor/hub assembly by resting the motor
struts on the lift structure or cribbing.
2. Feed the safety retention cable that is attached to
the motor/hub assembly up through the bottom
of the downtube until the loose end of the safety
cable is accessible at the top of the downtube. Pull
the loose end of the safety retention cable from the
top of the downtube until all of the slack is pulled
through.
3. Using a Phillips screwdriver, remove the front and
back VFD covers and set aside.

IMPORTANT: Do not allow safety cable or wiring to
be crushed while lifting the motor/hub assembly into
the downtube. Safety cable must be kept taut inside
the downtube in order to prevent damage. If either
the safety cable or the wiring are damaged during
installation, contact your local rep or the manufacturer.
NOTE: When leveling the fan, the level should be moved
around the circumference of the downtube periodically
to ensure that the fan is level.
