be kept in perfect condition at all times and must never be removed or
moved from their original position.
•
When troubleshooting for the cause of any malfunction of the fan,
ensure that all precautions described in this manual have been taken to
prevent personal injury and/or damage to property.
•
Remember to tighten every screw, bolt and lock ring of every component
subject to adjustment or maintenance.
•
Before starting the fan, ensure that all safety devices have been correctly
installed and are in perfect working order; if the above is not the case, do
not start the fan and inform the head of safety or department manager
immediately.
•
The operator must be equipped with Personal protection Equipments
in accordance with current legislation; the use of bulky clothing and
accessories (ties, loose sleeves, etc.) is prohibited.
2.3
Other risks related to fans
The following is a list of specific hazards related to the fan’s mechanical
characteristics.
WARNING!
Risk of personal injury.
A person may receive injuries as a result of:
•
Becoming caught up between a moving part and a stationary part, for example, between a
fan rotor and the fan housing or any other stationary fan component.
•
Becoming caught up between two moving parts, for example, between a belt and a pulley.
•
Suction of a part of the body into the fan and subsequent contact with the shaft or rotor.
•
Contact with a moving part, such as the rotor.
•
An object becoming sucked into the intake of the fan and expelled at high speed from the
outlet of the fan.
•
Contact with surfaces of the fan at dangerous temperatures, for example, temperatures
below -20°C or above +50 °C.
•
Hazards caused by the overspeed of a fan component, which can lead to the breakage of
parts of the machine.
•
The aspiration of air at temperatures above the specified operating range, which can lead to
the deformation and breakage of the housing.
2.4
Specific risks involved in transport and installation
•
Before installation, the user must prepare a perfectly level surface onto
which the fan will be mounted. If this surface is not perfectly level, this
can cause abnormal vibrations in the fan. This can, over time, lead to the
deformation and/or breakage of fan components with the subsequent
expulsion at speed of broken parts: these expelled parts can cause even
fatal injuries to any persons exposed.
•
Before installation, the user must also prepare adequate connections to
earth for the fan case or for the fan structure to prevent the build-up of
electrostatic charges.
•
All installed protective devices must remain fixed to the fan together
with their respective fixings (screws, bolts, etc.). The removal of one or
