WARNING

 Use of the fan other than as described in the user manual or outside the 

operational limits laid down by the manufacturer is considered IMPROPER USE. In 
the event of IMPROPER USE the manufacturer declines all liability in relation to any 

damage  that  may  be  caused  to  persons  or  property,  and  any  kind  of  warranty  will  be 
considered invalidated. 
 

 
Use of non-original spare parts 

Original spare parts ensure the reliability and safety of the operation of the fan: in the event of 
maintenance/replacement, consult the spare parts list, the list of parts and components used 
and the relevant technical documentation attached to this manual. 
 

WARNING

 In the event of replacement of safety devices, it is essential to maintain 

the  safety  and  operational  characteristics  of  the  original  device,  preferring 
replacement with an identical component. 

 

Insufficient maintenance 

correct normal maintenance is one that maintains the original integrity or restores the fan’s 

efficiency, while at the same time limiting normal deterioration resulting from use. 
Special maintenance work can also prolong the usable life of the machine and/or, secondarily, 
can improve its efficiency, reliability, productivity and ease of maintenance and inspection. 
 

Unauthorized modifications or tampering 

No operation is permitted which is aimed at making modifications to the fan and the safety 
devices  fitted  to  it;  similarly,  it  is  not  possible  to  alter  its  operational  and  performance 
characteristics. 

 

WARNING

  Interference  with  the  command  and  control  circuits  is  prohibited:  such 

operations  could  cause  damage  to  the  equipment  and  serious  danger  to  the 
operator. 

 

NOTE

 Modifications made to the fan which do not come into the categories of normal 

and  special  maintenance,  or  which  alter  its  operational  and  performance 
characteristics,  invalidate  the  machine’s  compliance  with  the  requirements  of  the 

applicable directives, as attested by the manufacturer with the EC declaration of conformity: 
it  is  up  to  the  person  responsible  for  the  modification  to  resubmit  the  machine  to  the 
assessment conformity procedures specified in the applicable directives.
