Installation and start up
Don’t install this machine before having read these instructions. Keep them for further technical operations
and/or maintenance operations.
Preliminary checks
Installation area:
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.
Supports:
All the supports have to be: enough strength to hold the weight of the fan and with the right stiffness for vibrations
(expecially when starting up).
Ordinary vibrations caused while functioning depend mainly on the rigidness degree of the structural element
where the fan is placed.
In this sense, it is highly recommended that in those models that there is this possibility, elastic shock absorbers
should be installed (either made with rubber or springs) to avoid transmission of vibrations and noises, keeping
the fan in a floating position.
To complete correctly this insulation with the rest of the conducting installation, elastic joints should be placed
in the suctioning inlet and outlet of the fan.
Also, installing the product on a rigid plan is possibile, as well on concrete bases or walls, but the rigid plan have
to be perfectly planar and correctly aligned.
Anyway: never force the fan structure by tightening the screws.
Base:
The platform (floor or roof) where the appliance is to be positioned is both flat and smooth and capable of safely
bearing its weight. The bottom horizontal base have to be perfectly planar and aligned. Beforehand small strips
of aluminium sheets, washers, or fast cement should be placed in the gaps to fill the space ensuring the correct
support of the fan.
Point of the power supply:
A special attention should be placed on reinforcing the charging point of the fan and make sure that the
waterproof property is not affected by the vibrations.
Correct mounting
Fans installed on the roof or wall, or those which use a supporting system or any additional structure, should be
levelled correctly horizontally and vertically.
In horizontal bases such base should be flat and levelled, and in cases where there is a concrete base it should
be perfectly flat.
Note: The appliance must be installed in such a way that the shaft of the motor runs parallel to the ground.
Electrical connections
Each model fan has a connection drawing inside the terminal box. IMPORTANT: The feeding cable connection
should be done inside such terminal box of the motor or fan. Pass the power supply cable into the casing through
an appropriately sized grommet.
It is important that the feeding lines and other components used in the installation meet the requirements of the
valid regulations of industrial installations and that the protection system are in accordance to the power of the
fan (Motor protection system, differential protection, wiring limit and ground system).
For motors over 7.5 HP (5.5Kw) is also suggested to perform a timed limit relay start up or control it electronically
so nor excess consumption peaks occur and ensure a smooth start up.
NOTE: Avoid connecting single phase appliances to 3-phase line shunt connections.
