fig.1
For operation of fan installation, a manoeuvring area must
be made available that is suitable for the fan dimensions
and the chosen lifting equipment: electrical points must be
provided in the installation area for fan connection to the
mains electricity supply.

The fans must be installed at a height of not 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
manufacturer, to protect the internal rotor. Failure to install
the safety mesh releases manufacturer from all liability and
shall be considered an improper use of the machine.
There must be no obstacle neither in front or
behind the fans. The outgoing airflow must be
kept free at least of a length of 3-times fan
diameter and the ingoing airflow must be kept free at least
in a radius of 1.5 m distance in front of the fan.
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 allow the air to exit freely. It
is also prohibited for anyone to remain in this area, because

mesh supplied by
of the presence of organic gases and dust which may be
present in the airflow.
The fans must be installed to carry out
extraction or an internal circulation of the air
present in the area, and must not operate under
pressure. It is also permissible to install the fan
in a horizontal position.
Installation of the fan. Fans have to be installed
taking care to have central support placed in
correspondence of a concrete wall or a
dedicated metal frame, which has to be strong enough to
support the weight of the fan. This is mandatory for
guaranteeing the correct functioning of the fans eliminating
vibrations and avoiding possible malfunctioning.
5.2 Installing Series EM fans
If the fan is fixed directly to a metal structure, M8 bolts type
8.8 must be used, screwing them into the threaded inserts
provided for the purpose on the bodywork (two per side). If
the fan is installed in a masonry structure, an iron outer
the
frame must be constructed (not supplied with the fan), with
a 60 mm L-shaped profile at least 5 mm thick, with suitably-
sized clamps. When the outer frame is properly built-in, i.e.
perfectly level and upright, insert the fan, screwing four M8
bolts type 8.8 (not supplied with the fan) into the threaded
inserts provided on the sides of the bodywork, two per side.
5.3 Installing Series EMS fans
For installing type EMS fans in metal or masonry structures,
the procedures described on the previous page for model
EM fans also apply. If installed for recirculating air, it is
sufficient to attach chains or cables to the M8 threaded
holes at the ends of the top cover.
5.4 Connection to the electrical system
The fan is supplied without a command and control circuit,
but with all the internal electrical connections already made.
At the fitting stage, the installer must set up a control panel
in compliance with the requirements of standard IEC EN
60439-1, and arrange the wiring of the fan in accordance
with the instructions in standards IEC EN 60204-1 and IEC
60364 (see fig.2).
