9. FAN INSTALLATION AND OPERATION
9.1 VERIFY
For fans due to be installed directly onto a roof, correct horizontal and vertical levelling of the apparatus must be
carried out, even if a support system or an additional structure is being used, Horizontal bases must be perfectly
levelandsetinaconcretebase.Adequatesupportswithsufficientresistanceandrigiditytosupportthefanweight
should also be installed. For roof fan products, special attention should be paid to reinforce the loading point of
thefanandensurethattheroofwatertightnessisnotaffectedbypossiblevibrationsoftheapparatus.Normal
vibrations of the apparatus during its operation depend mainly on the rigidity of the structure where the fan is to
be installed.
If dampers are necessary to avoid vibrations and noise, only metal springs should be used. F400 - approved elastic

It is important that these isolation elements do not alter the security compliance of the installation.
In rigid installations on cement bases or walls which are not correctly aligned, never force the fan structure by
tighteningthescrews.Beforeinstallation,anygapsshouldbefilledwithsmallstripsofmetalorwithwashers,

9.2 ELECTRICAL CONNECTION AND INSTALLATION
Each fan's wiring diagrams are available inside the connection box of the motor. PLEASE READ THE INSTRUCTION
MANUAL FOR F400 CAREFULLY. IT IS IMPORTANT THAT POWER SUPPLY LINES AND OTHER COMPONENTS USED IN
THE INSTALLATION COMPLY WITH THE
REGULATIONS ON INDUSTRIAL INSTALLATIONS ("Low voltage electrical regulation") and therefore protection
systemssuitableforthevoltageoftheapparatusshouldbeused(motorprotectionsystem,differentialprotection,
line limiter and grounding). For motors superior to 7,5 CV (5,5 Kw), timed or electrically controlled start-ups are
recommended in order to avoid excessive consumption points and to achieve more gentle start-ups. In some
models in the middle and high voltage centrifugal fans, a regulation shutter or valve completely closed during the
fan's start-up to reduce consumption will be enough.
The cable or cables used should be properly protected to avoid any damage to the fan's structural components or
their backups, and must comply with the pertinent F400 technical requirements.
