1. Safety aspects

Failure to respect safety or behavioural rules
can produce hazardous situations for users as
well as damage to the machine and the place

where it is installed. The fan must only be used
if it is in perfect operating condition, by personnel who
are perfectly aware of the safety measures and possible
hazards, and in strict compliance with the instructions
given in this manual.

1.1 PERSONNEL REQUIREMENTS

Equipment may only be used by personnel who know
and apply the specific requirements given in the user
and maintenance manual and the more general
instructions contained in various regulations for accident
prevention and applicable legislation regarding safety
in the workplace. Knowledge and understanding of the
manual and of the attached documents constitute an
indispensable tool for reducing hazards and promoting
the safety and health of workers.

Personnel training

All operators engaged in the use of the fan must have
received adequate information from the employer
relating to:

• risks to health and safety at work connected with the

• use of the machine;

• first aid procedures, fire precautions and evacuation

of workplaces;

• devices provided for the safety of operators, and
residual risks generated by the machine.

In particular, the employer has the following duties:

• when assigning tasks to operators, to take into
account their capabilities in the interests of
safeguarding their health and safety;

• to provide adequate means of protection;

• to require compliance by individual operators with

the company rules and provisions regarding safety
and the use of the collective and individual protective
measures at their disposal;

• to ensure that normal and special maintenance
operations, or in any event operations necessary for
machine safety, are regularly carried out.

All operators must take care of their own safety and
health as well as that of other people in the workplace
who may be affected by their actions or omissions, in
accordance with their personal skills, and the instructions
and means provided to them by the employer.

Unauthorized tampering/replacement of one
or more parts of the machine, or the use of

accessories, tools or materials other than those
recommended by the manufacturer, are prohibited and
release the manufacturer from all liability.

Operators must be trained to deal with the

occurrence of possible faults, malfunctions or

dangerous conditions to themselves or others,
and in such an event must:

• stop the fan immediately by operating the emergency
stop device (mushroom-shaped push-button/main
switch mounted on the electrical panel);

• not carry out operations which are beyond their
duties and/or technical knowledge.

1.2 GENERAL SAFETY INSTRUCTIONS

•Safety devices must not be removed or
rendered ineffective;

•the fan must not be started with guards

removed;

• any adjustment or maintenance operation must
be performed with the electrical isolating device
activated and locked in position with a padlock;

• any operation is prohibited which may cause arcing
or sparks or other situations which could start a fire;

• in the event of alarm signals resulting in the
intervention of safety devices, the operator must
ask for immediate action by qualified technicians
responsible for maintenance;

• user must ensure that the environmental and
electricity supply conditions in which the fan
operates are always within the limits specified in this
user manual;

• do not for any reason modify parts of the fan in
order to fit additional devices.

1.3 SAFETY DEVICES

In the process of designing and building the fan,
the manufacturer adopted the necessary technical
solutions to ensure compliance with fundamental safety
requirements: the object of the risk reduction process
was to ensure that the operator can use the fan in safety.

Fixed guards

The fixed guards are solidly fixed to the structure of
the machine and cannot easily be eluded: the guards
are fixed with systems which require the use of tools for
dismantling.

Do not start the fan with fixed guards removed:
the guards can only be removed with special

tools, by specialized and trained personnel
and with the system stationary (emergency system
activated and electricity and hydraulic fluid isolated).
At the end of maintenance operations, the guards which
were removed must be replaced correctly.

1. Position of guard: intake side of fan
Type of guard: guard of fixed type made of metal
mesh

2. Position of guard: outlet side of fan
Type of guard: guard of fixed type made of metal
mesh

Emergency stop function

The machine must be equipped at the installation stage
with an electrical panel, on which must be installed
an actuator for the emergency stop function, which
when operated brings dangerous movements to a halt
by isolation of the power supply: the button must be
mushroom-shaped and coloured red, provided with
mechanical restraint and released by turning.

1.4 RESIDUAL RISKS

Electrical hazards

System area: panels, covers and electrical apparatus.
Description: the safety signs must be fixed in an extremely
visible position on the door of the electrical panel and on
covers containing electrical apparatus, to highlight the
risks to which an operator could be exposed in the event
of opening the electrical panel (danger resulting from
the presence of live parts), the level of voltage present,
the prohibition of tampering by unauthorized personnel
and the prohibition on the use of liquids on electrical
apparatus in the event of fire.

The user and the employer must comply with
current national law in terms of protection

against daily personal exposure of operators
to noise, by providing the use of personal protective
equipment (earmuffs, earplugs, etc.) if necessary,
depending on the overall level of sound pressure in
the installation area, and the daily personal exposure
of the employees. In areas where the overall sound
level reaches excessive values, personal protective
equipment must be used.

2. Operating conditions

2.1 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.

2.2 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,
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.

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
not intended to handle materials which release explosive
dust. Emission into the atmosphere of harmful particles or
gases must be contained within the limits established by
current regulations.

3. Installation

After fan has been delivered but before fitting and
installation, check condition of the consignment: in the
event of discrepancy or damage to the machine, the
manufacturer or carrier must be informed immediately.

Fitting and installation of the fan must be
performed by specialized personnel, in order
to prevent damage to the equipment or
