Installation
Before beginning installation, make sure that:
• the platform where the appliance is to be positioned
is both flat and smooth and capable of safely
bearing its weight.
• the power supply matches the characteristics
shown on the ID plate.
• the area where the appliance is to be positioned
offers enough room for installation and later
maintenance work. There must be enough room on
the inspection panel side of the appliance for the
panels to be fully opened and for components to be
removed should the need arise.
The appliance must be installed in such a way that
the shaft of the motor runs parallel to the ground. In
the case of a fan with twin intakes, the ducts have to
be fitted to the specific delivery outlet and to one of
the
intake
panels to be selected at the time of
installation after cutting an opening that is at least as
large as the delivery outlet.
It is not recommended that you use ducting with
bends in the immediate vicinity of the appliance, as
the flow of air generated requires a straight section at
least 3 or 4 times the equivalent diameter of the duct
to reduce the vertical air flow to normal.
The appliance is statically and dynamically balanced
to level 6.3 according to ISO 1940 standards,
however the use of vibration dampers on the base is
recommended.
