The user must also bear in mind the risks inherent in maintenance work, which must
always be carried out in conditions of the utmost safety, with the fan separated from the
motor or isolated using suitable equipment.
Once the installer and/or user has decided which installation type is to be used and all the
above procedures have been applied, the machine can now be considered a “complete
machine” as described by machine use regulations. An overall risk evaluation must be
made. With regard to guards to be fitted to ducts, in compliance with the design project,
they must prevent access to parts of the fan and its accessories that could cause injuries.
They must also be sufficiently robustly constructed to resist the stresses generated by the
machine and environmental conditions.
Nederman invites users and/or system designers to design, construct and install guards in
conformity with the criteria of the UNI EN ISO 12499 standard.
The installer and the user must also take other types of risk into consideration, and in
particular those deriving from the entry of foreign bodies and the intake of explosive,
inflammable or toxic gases or gases at a high temperature.

4.4.1
Transport and lifting
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.
CAUTION!
Risk of equipment damage.
•
The user assumes liability for the choice of the lifting equipment and ropes, straps or
chains considered to be most suitable both for the purpose and for their lifting capacity.
For lifting and movement, do not use zones or points other than those marked by a
symbol. See
Table 2-1: Explanation of sign and sticker symbols used on the product.
.
•
All transport operations must be carried out only by qualified personnel, equipped with
the correct PPE for protection against blows and/or falling object.
•
The movement of separate or disassembled parts of the machine must be carried out
with suitable means of transport.
Lifting and movement operations with the fan may create hazardous situations for exposed
persons. It is therefore advisable to follow the instructions provided by Nederman and to
use suitable equipment.
It is advisable to carry out all lifting and movement operations on the fan and its
components with extreme care, avoiding impacts that may affect its correct operation or
damage covered parts.
Use only the points indicated to lift the fan, distributing the load in a uniform manner.
4.4.2
Lifting NCF fans
CAUTION!
Risk of equipment damage.
The lifting lugs on motors must never be used to lift the fan.
NCF fans are complete with motor. To lift them, only the specific holes provided in the
structure should be used (as shown in Figure 7). These holes are located on opposite sides
above the centre of gravity, and are indicated by specific symbols.
