WARNING!
Risk of personal injury.
•
All installation and assembly operations may only be carried out by qualified personnel,
equipped with the correct PPE for protection against blows and/or falling objects.
•
Do not start any maintenance work on the fan (including lubrication) without first
disconnecting the fan from the main power supply.
•
Be careful of the impeller during maintenance and cleaning of the impeller. This can lead
to parts of the body becoming trapped and seriously injured between the impeller itself
and fixed parts of the fan housing.
•
Avoid rotating parts. 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 impeller itself and fixed parts of the fan
housing.
•
Do not carry out any type of maintenance operation without having first checked that
the fan impeller is effectively at a standstill. The impeller takes several minutes to stop
after the drive system has been switched off.
•
Do not proceed with any type of maintenance operation on the fan (including
lubrication) without having first disconnected it from the mains powers supply.
•
Do not clean the fan while it is operating.
•
Do not open fan guards or inspection hatches while the fan is operating.
CAUTION!
Risk of equipment damage.
•
Periodic cleaning and maintenance are essential to ensure correct fan operation and a
longer operative life span of the fan.
•
A fan maintenance program must be drawn up and followed to prevent the mechanical
failure or breakage due to wear or insufficient maintenance.
•
The fan must be disconnected and isolated from the electrical power supply during
maintenance operations. Always check that the impeller and motor are at a standstill
before accessing the fan and its components or opening the inspection hatch. In the
case of fans that move hot fluids, wait for the fan to cool down before carrying out
maintenance operations, so as to prevent contact with surfaces at high temperatures.
•
Any necessary movement of parts to be removed or disassembled from the machine
must be made with suitable transport and lifting equipment.
•
Full systematic maintenance of the fan is necessary for its normal correct operation, and
is also a factor of safety for operatives.
NOTE!
An integrated maintenance program is necessary for normal and correct operation
of the fan, and also ensures greater safety for the operator.
NOTE!
Regular cleaning and maintenance are vital for ensuring correct operation and
greater durability of the fan.
Read Chapter 2 Safety before carrying out maintenance.
The safety rules to be respected during maintenance operations on the fan are as follows:
•
Maintenance operations must be carried out only by qualified and expert personnel,
authorized by the technical management of the factory, in conformity with applicable
safety directives and standards, using tools, equipment and products suitable for the
purpose.
