4. Operating conditions

4.1 INTENDED CONDITIONS OF uSE

Fans, fanjets and circulators are machines designed
for moving air to control temperature and humidity in
greenhouses or rearing sheds, by extraction or internal
recirculation, not under pressure, and can even be
installed horizontally, without altering or modifying their
characteristics. The fan has been designed and built to
operate in safety for the user, if used according to the
conditions intended by the manufacturer and stated in
this user and maintenance manual.
For further information, please refer to the
!
technical documentation attached to this
manual.
4.2 NON-PERMITTED CONDITIONS OF uSE
Total or partial failure to observe the instructions given
in this manual could cause damage to the fan and/or
people.
The following uses are to be considered not permitted
and improper:
• use in the event of faults and/or tampering with the
installed safety devices;
• use by personnel not specifically trained;
• installation of the fan for extraction or circulation
under pressure;
• use contrary to existing regulations;
• incorrect installation differing from instructions given
in this manual;
• supply from an electrical network with characteristics
different from that specified in the wiring diagram;
• total or partial failure to observe instructions;
• insufficient maintenance;
• use of non-original spare parts;
• use of lubricants with characteristics different from
those specified in the technical documentation
attached to the manual;
• use by minors;
• use under the influence of drugs, alcohol, etc.
Use of the fan other than as described in the
!
user manual or outside the operational limits
laid down by the manufacturer is considered
IMPROPER USE. In the event of IMPROPER USE the
manufacturer declines all liability in relation to any
damage that may be caused to persons or property,
6
and any kind of warranty will be considered invalidated.
use of non-original spare parts
Original spare parts ensure the reliability and safety of
the operation of the fan: in the event of maintenance/
replacement, consult the spare parts list, the list of
parts and components used and the relevant technical
documentation attached to this manual.
In the event of replacement of safety devices,
!
it is essential to maintain the safety and
operational characteristics of the original
device, preferring replacement with an identical
component.
Insufficient maintenance
A correct normal maintenance is one that maintains the
original integrity or restores the fan's efficiency, while
at the same time limiting normal deterioration resulting
from use. Special maintenance work can also prolong
the usable life of the machine and/or, secondarily, can
improve its efficiency, reliability, productivity and ease of
maintenance and inspection.
unauthorized modifications or tampering
No operation is permitted which is aimed at making
modifications to the fan and the safety devices fitted to
it; similarly, it is not possible to alter its operational and
performance characteristics.
Interference with the command and control
!
circuits is prohibited: such operations could
cause damage to the equipment and serious
danger to the operator. Modifications made to the fan
which do not come into the categories of normal and
special maintenance, or which alter its operational and
performance characteristics, invalidate the machine's
compliance with the requirements of the applicable
directives, as attested by the manufacturer with the
EC declaration of conformity: it is up to the person
responsible for the modification to resubmit the machine
to the assessment conformity procedures specified in the
applicable directives.
use in a potentially explosive atmosphere
The fan has been designed and built to operate in
environments where the presence of a potentially
explosive atmosphere is not expected, in other words it is
