•
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
