more fixing may compromise the functionality and tightness of the safety
shield.
• In its standard form, the fan is not intended for use in a potentially
explosive environment.
•
The installation location of the fan must be kept clean at all times. Any
eventual oil or water spillages not caused by the fan must be removed
immediately.
•
The minimum installation distances specified in the manual must
always be respected to ensure correct functionality without any further
hazards. The incorrect positioning of a component can compromise the
functionality of the fan.
2.5 Specific risks involved in fan maintenance
•
During maintenance and cleaning of the fan rotor, be particular careful
of the rotor. This can lead to parts of the body becoming trapped and
seriously injured between the rotor itself and fixed parts of the fan
housing.
• Even when the fan is disconnected from the power supply, the rotating
parts can still turn due to any air movement through the fan. This air flow
may be natural or may be caused by the current induced by another fan
installed elsewhere in the connected tubing system. This can also lead to
parts of the body becoming trapped and seriously injured between the
rotor itself and fixed parts of the fan housing.
•
A fan maintenance program must be drawn up and followed to
prevent the mechanical failure or breakage due to wear or insufficient
maintenance.
