If building support beam is not level, ensure proper
fan clearance using the mounting information shown
on page 6 or add mounting extensions as required to
ensure clearance. See Fig. 3.
If a mounting extension has been used, it may be necessary
to obtain a longer cable from a local supplier.

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. 8. Avoid any
sharp edges or corners to reduce fatiguing and fraying
of the guy wires.
