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.
Single phase motors
