  • Page 7: Important Information

    When mounting a fan in an area where objects may be lifted or moved into the path of the fan, Skyblade Fans recommends marking or painting hash lines on the floor to alert personnel of the above movement of the fan.
  • Page 8: Mounting Considerations

    The maximum torque that must be handed by the mounting system and the building structure will occur at the fans startup. For a 16 foot fan, maximum potential startup torque is 300 ft-lbs. Skyblade Fans use a soft-start technology which allows the rpm to ramp up as desired over 60 seconds. The event of this max torque being applied is unlikely and will only apply due to a failure of the variable frequency drive and its soft start technology.
  • Page 9: Preparing The Work Site

    Skyblade Fans can only be hung from an I-beam or angle irons. See installation instructions on the following page. Do not mount the fan to single purlins, trusses, or bar joists. Consult a structural engineer for installation methods not covered in the manual.
