NCF fan
6 Maintenance
Read this section carefully before carrying out maintenance operations on the NCF fan. This will ensure greater
conditions of safety for maintenance personnel and greater reliability of the work done.
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 NCF 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 and fixed parts of the NCF fan
housing.
• Avoid rotating parts. Even when the NCF 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 NCF fan housing.
• Do not carry out any type of maintenance operation without having first checked the NCF 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 NCF fan (including lubrication) without
having first disconnected it from the mains powers supply.
• Do not clean the NCF fan while it is operating.
• Do not open NCF fan guards or inspection hatches while the fan is operating.
CAUTION! Risk of equipment damage
• Periodic cleaning and maintenance are essential to ensure the correct NCF fan operation and a longer
operative life span of the fan.
• A fan maintenance program must be drawn up and followed to prevent mechanical failure or breakage
due to wear or insufficient maintenance.
• The NCF 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 NCF 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 sur-
faces 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.
• Complete systematic maintenance of the NCF 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 the normal and correct operation of the NCF fan,
and also ensures greater safety for the operator.
• Regular cleaning and maintenance are vital for ensuring correct operation and greater durability of the
NCF fan.
Read
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 tech-
nical management of the factory, in conformity with applicable safety directives and standards, using tools,
equipment and products suitable for the purpose.
• During maintenance operations, suitable clothing must be worn, such as closely-fitting overalls and safety
footwear, absolutely avoiding bulky garments or loose parts.
• During maintenance operations on the NCF fan, it is advisable to fence it off and to identify it with signs with
the wording: “FAN UNDERGOING MAINTENANCE”.
