Installation
WARNING!
Risk of personal injury.
•
All installation and assembly operations must be carried out only by qualified personnel,
equipped with the correct PPE for protection against blows and/or falling objects.
•
Before installation, the user must provide a well-levelled fixing surface. Incorrect
levelling may cause abnormal fan vibrations that over time could cause deformation
and/or breakage, with the detachment of fan parts, representing a hazard for exposed
persons that may even be fatal.
•
All guards installed must remain correctly connected to the fan with all relative fasteners
(bolts, nuts, etc). The removal of one or more fixing points may impair the functionality
and solid fixing of the guard.
•
Fans supplied as standard versions are not intended for use in potentially explosive
environments.
•
The safety measures adopted for using the fan must also be tailored to suit the specific
applications for which the fan will be used. The safety measures taken differ depending
on the type of fan installation. Therefore, the information in this manual is indispensable
for the appropriate and hazard-free use of the fan.
