Guy wires are designed to constrain lateral movement of the
fan in operation. This movement may be due to impacts on
the fan or winds impinging on the blades that would cause
the fan to sway.
Failure to attach guy wires may result in loss of warranty.
If a mounting extension has been used, ensure that the
longer guy wires accompanying the extension are used.
Ensure that the angle formed by the guy wire with the
roof structure is less than 45º. See Fig. 10. Avoid any
sharp edges or corners to reduce fatiguing and fraying
of the guy wires. Failure to attach guy wires may result
in severe injury or death.
1. Adjust turnbuckles to their longest position.
2. Attach the quick link with attached turnbuckle to the fan
as shown. Repeat for all four quick links.
3. Attach one end of the guy wire to the building structure.
Ensure the structure has sufficient strength to withstand
the wire tension. Repeat for all four guy wires.
a. Slide two of the supplied 1/8" dia cable clamps over
one end of the wire.
b. Feed that end of the wire though the building structure
and back through the clamp fasteners.
c. Securely tighten the clamp fasteners so that it cannot
slip. Make sure the u-bolts are over the free end of
the cable.
4. Individually tighten the turn buckle on each cable until
each cable is taut and the powerhead unit hangs plumb.
Use a spirit level to verify powerhead unit hangs plumb.
5. Tighten pivot and angle adjustment bolts on fan mount.
Torque to 44-48 ft-lbs. See Fig. 3.
