laws and in force in the place of use of the machine. Lacking these requirements may cause damage to people's
health and safety. Use the personal protective equipment indicated in the manual.
In the EXTRACTION FAN version
The machine contains potentially explosive dust deposits and/or gases, therefore it is forbidden to
approach or introduce in the machine any possible ignition source:
• Naked flames
• Hot surfaces
• Sparks
• Gas
• Live electrical parts
• Electrostatic charges
2.3. SAFETY WARNINGS FOR HANDLING, ASSEMBLY AND INSTALLATION
Use adequate lifting equipment for handling and adopt all the safety precautions designed for activities carried
out in the work site.
In the EXTRACTION FAN version
The electrostatic charge accumulated by the exible pipes might ignite a re. Therefore, they must
have electrical conductivity and be earthed.
In the EXTRACTION FAN version
The machine must be installed in an area where there is no explosive atmosphere.

EXTRACTION FAN See the packing list accompanying the
shipment
See section "3.2. Directions for
machine assembly"
Provide a delimited and adequate area, with level floor or surface, for unloading and depositing packs.
It is always advisable to keep the packs horizontal during handling in order to avoid losing stability and/or them
overturning.
For lifting, please refer to the paragraph "3.3. MOVING THE MACHINE".
3.2. DIRECTIONS FOR MACHINE ASSEMBLY
Before assembly, visually inspect the material to make sure it was not damaged during
transportation. If there are signs of damage, inform the seller within 10 days from delivery.
Before proceeding with assembly, read paragraph "3.4. MACHINE INSTALLATION MODE".
For transport reasons and/or due to particular agreements stipulated between the customer
and the supplier, the parts required to assemble the machine may be different than those
described in the assembly phases.
Prior to opening the packaging, tilt the cage to prevent the material from overturning. Do not
exceed the maximum angle indicated in the gure.

Prior to assembly, it is necessary to determine the weight of the preassembled components
in Para "4.4. TECHNICAL DATA" .
For the lifting of the individual sub-assemblies, see section "3.3. MOVING THE MACHINE".
To handle components, proceed as follows:
•Locate the lifting pick-up points, as shown in the assembly steps, and use slings and
hooks.
•Prepare for lifting with cranes (gantry crane or forklift truck).
•Make a rst, very slow lifting manoeuvre, keeping the component as close as possible to
the ground to ensure that the load is balanced.
The Extraction Fan arms can be installed on wall shelf, stand and on trolley machines.
There are two different supports: rounded (zinc-coated and painted) and squared (stainless steel) For further
