Seal all seams and joints to prevent moisture from entering or air from leaking.
It is very important that your fan is adequately supported!
If a concrete pad is not used, an angle iron frame may be constructed for the fan to rest
on, providing it is strong enough to support the fan’s weight. Two support cables should
also be used in conjunction with the angle iron frame, running from the top portion of
the fan to the adjacent bin wall stiffeners. See fan manual for further details.
