less than 2.7 m from the ground. If they are
installed at a lower height, the fans must be
fitted with the optional safety mesh supplied by the

install the safety mesh releases manufacturer from
all liability and shall be considered an improper use
of the machine.
Irrespective of the place of installation, suitable indelible
warning signs are attached to the fan, warning of danger
and giving instructions to remain at a safe distance not to
place hands inside the shutter and not to run in proximity
of the fan. The warning signs are yellow, self-adhesive
and indelible. They are fitted to the front and rear of the
fan, and marked with the numbers A-1997 and B-1997
(see fig.1). The area adjacent to the fan in the premises
from which air is being extracted must be kept clear to

present in the area, and must not operate
under pressure. It is also permissible to install the fan in
a horizontal position.
