Fan is wobbling

Your HVLS fan is wobbling at any speed? Follow these troubleshooting steps.

1. Lockout and tag out the fan until troubleshooting is complete.
2. Verify the fan is installed using a standard mounting method. If not, ensure there is approval from a structural engineer for the mounting method.
3. Check that the fan is hanging plumb and horizontally level.
4. Check that all mounting bolts and blade bolts are properly installed and torqued.
5. Verify the airfoils are all at the same level — ensure one blade or more is not higher or lower at the tip than the others.
6. If all of the above is correct, install guy wires.
