SAFETY INSTRUCTIONS
In this Manual, certain particularly important pieces of
information may be preceded by one of the following
symbols:
WARNING!
This symbol indicates risks that can
cause personal injury!
This symbol indicates possible risks of
personal injury due to Electrified
components.
This symbol indicates particularly
important information of general
interest.
Installation
There are four possible installation types, in
compliance with UNI 10615 specifications:
•
Type A: open intake and outlet.
•
Type B: open intake and outlet connected to a pipe.
•
Type C: intake connected to a pipe and open outlet.
•
Type D: intake and outlet connected to a pipe.
Clearly AB Ph. Nederman & Co cannot be aware of
which of these four installation types will be used by the
user. Therefore, the installer or end client themselves
must analyze the risks involved for the chosen installa-
tion type used in the specific application.
Depending on the applications that the client intends to
use the fan for in the factory and on the type of installa-
tion chosen, the following safety shields must be fitted:
•
Type A installation: fixed shields at the intake and
outlet.
•
Type B installation: shield fitted only at the outlet.
•
Type C installation: shield fitted only at the intake.
•
Type D installation: no shield at either the intake or
outlet.
The shielding must be constructed to impede access to
the parts of the fan that could cause injury. It must be
robustly built enough to stand the vibrations and stress
caused by the machine and by environmental condi-
tions. It must be securely fixed in position by devices
that will not become loosened by vibrations and that
cannot be removed without the use of tools.
It is, in any case, the person installing the fan who is
responsible for ensuring that adequate measures have
been taken to prevent accidental contact with the fan’s
moving parts.
The installer and the user must also take into account
other types of risks present, in particular those caused
by foreign matter entering the fan and the aspiration of
explosive, inflammable or toxic gases at high tempera-
tures.
The user must also bear in mind the risks inherent in
maintenance work, which must always be carried out
in conditions of the utmost safety, with the fan sepa-
rated from the motor or isolated using suitable equip-
ment.
Once the installer and/or user has decided which
installation type is to be used and all the above pro-
cedures have been applied, the machine can now be
considered a “complete machine” as described by
machine use regulations. An overall risk evaluation
must be made.
Risks involved in incorrect handling or use
•
Never, for any reason whatsoever, disable,
remove, modify or render inoperative in any other
way any of the safety, protective or control devices
of any single component or of the fan itself.
•
Never place hands, arms or any other part of the
body near any moving part.
•
Never extend any part of the body past the limits
of the safety barriers. Do not use any means that
will increase normal accessibility to the fan compo-
nents.
•
Never use the fan in atmospheres where there is a
risk of explosion.
•
Unauthorized operators must not attempt to rectify
any malfunction of the fan and/or modify the func-
tional characteristics or and installation type.
•
After any un programmed maintenance operation
that required the removal of shields, barriers or any
other protective device, before restarting the fan
ensure that all these components have been refit-
ted and are fully functional.
•
All protective and safety devices must be kept in
perfect working order at all times. All indicative and
warning plates fixed to the fan must also be kept
in perfect condition at all times and must never be
removed or moved from their original position.
•
When troubleshooting for the cause of any mal-
function of the fan, ensure that all precautions
described in this manual have been taken to pre-
vent personal injury and/or damage to property.
•
Remember to tighten every screw, bolt and lock
ring of every component subject to adjustment or
maintenance.
•
Before starting the fan, ensure that all safety
devices have been correctly installed and are in
perfect working order; if the above is not the case,
do not start the fan and inform the head of safety
or department manager immediately.
•
The operator must be equipped with Personal pro-
tection Equipments in accordance with current leg-
islation; the use of bulky clothing and accessories
(ties, loose sleeves, etc.) is prohibited.
