Munters EM52 Manual De Uso Y Mantenimiento página 5

Type of guard: guard of fixed type made of metal
mesh
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.

EM52 - 2.0hp
EM/EMS50 - 1.5hp

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.
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 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
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;
• use by minors;
