WARNING!
Risk of personal injury.
The user is responsible for the selection of equipment, ropes, belts and chains
best suited for both load and functionality.
4.3.2
Storage in a warehouse
Should it be necessary to store the fan in a warehouse, it must be protected
from atmospheric conditions, humidity, dust and any harmful substances
present in the air.
WARNING!
Risk of personal injury.
It is absolutely forbidden to:
•
Carry out any maintenance work without first ensuring that the fan rotor is
effectively stationary.
•
Start any maintenance work on the fan (including lubrication) without first
disconnecting the fan from the main power supply.
•
Clean the fan while it is running.
•
Open any shield or inspection hatch while the fan is running.
We recommend that you periodically check that the fan is in a good condition
and turn the fan rotor manually approximately once a month to prevent the
deformation of its bearings.
WARNING!
The examples given are generic examples as it is impossible to know in
advance every possible configuration for lifting a NCF fan.
4.3.3
Lifting NCF fans
NCF fans are equipped with a motor. When lifting these fans, as well as using
the specific holes in fan structure, the eyebolt for lifting the motor must also
be used (as shown in Figure 6).
4.4
Installation
The fan does not require the preparation of a special machine bed for its
installation. A well-leveled concrete surface that can support the weight of the
fan is sufficient.
NOTE!
Always use anti-vibration supports and couplings to prevent the
transmission of vibrations while the fan is running.
The support base must be perfectly level and flat to prevent torsion effects or
misalignment of the supports: if necessary, install metal shims between the
machine base and the concrete surface to ensure a perfect fit. Use the factory-
fitted anchoring points and take care not to deform the fan structure while
tightening bolts.
All connecting tubing must be supported separately and must be axially
aligned with the fan’s intake and outlet nozzles, to prevent any deformation
occurring while tightening the bolts.
WARNING!
All installation work must only be carried out by qualified and authorised
personnel using suitable equipment.
