General information
The Manufacturer refuses any liability for any damage originating from incorrect
or unwise operations.
It is strictly forbidden and dangerous to use the product
for different uses from those provided within the field of
application.
Normally intended use
This fan was designed to:
Product a flow of air, gas or steam by increasing their pressure,
with a variable flow rate and head according to the model.
The steam or gas must comply with the features of the model.
The fans suitable for explosion-proof environments (ATEX)
differ from standard fans as they are built with special
precautions in order to make them suitable to be used in
poptentially explosive environments.
In addition to the particular construction of the fan, particular monitoring and
maintenance are critical so as to maintain the fan safety requirements over time
and for its suitability for use in the potentially explosive environment it is placed in.
Strictly comply with the instructions in this manual in ad-
dition to that already required in the user and standard
maintenance manual and Attachment Ex.
In the case of different instructions in the two manuals, that
indicated in this manual is to be given priority.
Non authorised use
Personnel operating in potentially explosive environments
for installation, commissioning, maintenance and decom-
missioning purposes must be aware of the risks and pre-
cautions to be taken.
Such personnel must operate in accordance with current
regulations concerning potentially explosive atmospheres
ATEX 94/9/EC.
Non-conforming installation, commissioning, maintenance and decommissioning
of the fan is forbidden, as well as in environments with stricter characteristics
than those stipulated in the manual and on the plates on the machine.
Furthermore do not use the fan:
- with abrasive fluids
- in high oxygen content environments (> 21%)
- in low pressure environments (< 0.8 bar) or high pressure (> 1.1 bar)
- at forbidden speeds
- in combination with other machines or accessories that do not conform to the
ATEX directive
- without the correct wiring and configuration of the temperature control devices,
rotation or vibrations, when required
- without the air gap between the impeller and nozzle, when required
- in risk environments other than those intended
