Munters EM52 Manual De Uso Y Mantenimiento página 8

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
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 not intended
to handle materials which release explosive dust. Emission
into the atmosphere of harmful particles or gases must be
contained within the
regulations.
The fan has been designed and built in such a
way that it CANNOT operate in a classified
area, according to directive 1999/92/EC.
fan: in the event
limits established by current
The metal sheets used for constructing the fan
housing and shutter blades have a surface
coating made of an alloy of Zinc, Aluminum and
Magnesium classified as ZM120 (equivalent to 9 μm of
coating thickness on each side of the panels) which
corresponds to a corrosion resistance in salty mist of 1800
hours. Whenever it is intended to use the fans in ambients
characterized by the presence of particularly aggressive
agents (ammonia, clavulanic acid, etc.) the user, before
installing the fan at the installation site must verify that the
of
environmental conditions are compatible with the intended
use of the materials that compose the fan.
5. 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 hazards to
people as a result of faulty fitting.
Fitting the fan must be carried out according to the following
stages:
• positioning and anchoring the fan;
• connection to the mains electricity supply;
• operational testing and putting into operation.
5.1 Choice of site and checking installation
requirements
The user is responsible for preparing an area suitable for
installation of the equipment and complying with the
requirements laid down by European directives and national
law governing safety at places of work. Environmental
conditions for operating the equipment are as follows:
Ambient temperature during operation -15 °C / +40 °C
Ambient humidity during operation
Maximum operating pressure

Value refer to all the extraction fan models with the exception
of EM52, which works at 100Pa.
For operation of fan installation, a manoeuvring area must
be made available that is suitable for the fan dimensions
and the chosen lifting equipment: electrical points must be
provided in the installation area for fan connection to the
mains electricity supply.
