Due to the technical constructive complexity of the machine, assembly must be performed by
qualified staff that have completed specific training courses.
During assembly, installation and maintenance, the screws must be tightened according to the values provided
in the table. The tightening torques must be applied slowly and constantly using a torque wrench. Said values
must be decreased by 10% when using impact drivers.
The table refers to class 4.8 screws.

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 first, 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
