It is important to try to avoid close clearance. Where clearance turns out to be a real
problem, bear in mind that both longer down extension rods and shorter blades are
available for purchase. In any case, since the standard mounting is free swiveling, we
strongly recommend that all fans be guy wired as shown in fig.3.2. if close clearance is
involved, the fan must be guy wired. Where the fan frame is bolted directly to a rigid
beam, it may not require guy wiring.
3.3. Positioning
It is important that an HVLS fan not be positioned where a person could actually come in
contact with it. This means that a fan should never be mounted lower than 10' above the
floor. Similarly, if there is a mezzanine section in the facility, it is important that a fan not be
placed so close to the mezzanine, that a person on an upper tier could reach out and
contact the fan.
Wherever there is a potential for a forklift to elevate something into the fan, or people
working with long material inadvertently making contact with the fan, the floor directly
below the fan should be painted in such a way (i.e. a large crosshatched circle) so as
to alert workers to the fan above. In such cases, the fan may have to be guarded.
