Note: dimensions and positioning in accordance with
the instructions in the standard UNI EN 13857.
Removable only by means of special tool.
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.
3.4 Residual risks
Mechanical hazards
Part of machine/stage of use: installation of machine
Description: hazard arising from failure to observe
ergonomic principles, caused by excessive strain, i.e.
generic mechanical hazard during the moving and installing
stages of the machine.
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.
Hazards generated by noise
A measurement has been made of the noise produced by
the machine during normal operation in order to calculate
the equivalent level in conditions of normal use.
These values are shown in the following table.

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.
4. OPERATING CONDITIONS
Once unpacked check the opening of the
shutter manually by rotating the central shutter
blade. Verify that during transportation the
plastic shutter bearings did not fall off from their operation
condition. If yes restore them by mean of a screw-driver and
re-check the opening of the shutter.
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
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
manual.
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.
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;
