INSTALLATION
5.1
General information
CAUTION:
All assembly operations must be carried out only by qualified personnel, equipped with the
correct PPE for protection against blows and/or falling objects.
Generally, special or specific equipment is not necessary for the assembly of fan parts.
In the case of assembly of parts requiring a specific procedure, FVI
will provide the additional
information necessary for carrying out the operations correctly.
Special foundations are not necessary for positioning the fan. A well-levelled concrete support surface is
sufficient, suitable to withstand the weight load of the fan and the dynamic stresses generated by its normal
operation.
FVI
designs and constructs its fans dedicating the greatest possible attention to the elimination of vibrations
at their source. During installation, the user and/or installer must take the necessary measures to reduce
vibrations from the overall system (fan and ducts).
It is advisable to use anti-vibration supports and joints to reduce to a minimum the
transmission of vibrations during fan operation.
The support surface must be flat and horizontal, to prevent the bending and misalignment of supports. If
necessary, suitable metal spacers must be placed between the fan base and the support surface to ensure
perfect adherence. Use the fixing points provided, ensuring that the tightening of nuts and bolts does not
deform fan structures.
The support surface must be sufficiently rigid to withstand normal fan vibrations, and must not be subject to
phenomena of structural resonance.
If the fan is mounted on a structure raised above floor level, the vibration characteristics of this structure
must be verified.
The necessary and sufficient parameters for the definition of the technical characteristics of the support
structure to be used for fan installation are as follows:
static load of the fan
dynamic load of the fan
position of the centre of gravity of the fan
These data are given in the SCHT01 technical information sheet supplied together with the fan described in
this manual, or in the overall dimensions drawing.
The same information sheet also gives technical data for the type of vibration dampers and anti-vibration
joints to be used.
FVI does not consider fixing by means of welding the fan structure to foundation plates to be
an acceptable fixing method.
