4.4.3 Storage in a warehouse
CAUTION! Risk of equipment damage.
Close intake and exit openings during storage.
Should it be necessary to store the fan in a warehouse, it must be protected from
atmospheric condions, humidity, dust and any harmful substances present in the air.
It is recommend to periodically check that the fan is in a good condion and turn the
impeller manually approximately once a month to prevent the deformaon of its bearings.
4.5 Mounng
NOTE! The support surface must be suciently rigid to withstand normal fan vibraons,
and must not be subject to phenomena of structural resonance.
NOTE! If the fan is mounted on a structure raised above oor level, the vibraon
characteriscs of this structure must be veried.
Special foundaons are not necessary for posioning the fan. A well-levelled concrete
support surface is sucient, suitable to withstand the weight load of the fan and the
dynamic stresses generated by its normal operaon.
During installaon, the user and/or installer must take the necessary measures to reduce
vibraons from the overall system (fan and ducts).
The support surface must be at 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 xing points provided, ensuring
that the ghtening of nuts and bolts does not deform fan structures.
Ducng connected to the fan must be supported separately, and must be coaxial with
respect to the intake and exit openings, so as to prevent deformaon caused by the
ghtening of nuts and bolts.
4.5.1 Outdoor installaon
CAUTION! Risk of equipment damage.
• An IP55 motor will not be water ght in outdoor operang condions. The applicaon
where the motor is used, mounng posion and actual exposure to external factors
must be taken into account.
• Make sure there are draining holes in the fan casings for fans used in outdoor
installaons.
• Leave a bend on the cable before the motor so that water can run down and o of the
cable. See gure 11.
If the fan is to be used outdoors or under other circumstances where moisture and
condensaon can be present the motor must be protected by a suitable cover.
Make sure to have a draining hole in the lowest level of the fan casing. Drill a hole
(approximately Ø 5 mm). Then treat the hole with an ancorrosive agent.
4.5.2 Minimum distances between components
WARNING!
The access of personnel, even if qualied, to the intake area of fans capable of developing,
with zero ow, a negave pressure greater than 5000 Pa, must be prohibited.
