The non observance of the instructions shown
i
n this booklet or in the Operator’s Manual of the
pump exempts POMPETRAVAINI from any responsibility in case of damage to objects or injuries
to persons and makes any safety compliance for the pump invalid.
This booklet deals with the hazards when using this pump in
environment
of potentially
explosive atmospheres. The use of the centrifugal pump however cannot be considered
without any risk
coming from its use as the machine is provided with moving
components, electrical
connections, liquids under pressure etc. Independent from the safety
guarantees
which come by
observing the aforesaid indications, there might be some
amount
of risk which cannot be reasonably foreseen. Only the end-user in the context of his analysis
and classification of the
zones according to the provisions of the ATEX 1999/92/EC Directive
may be aware of them. The
safety during the use of the centrifugal pumps cannot be
separated completely from any
responsible use of the machine, of its accessories and of
the plant to which these items are
connected.
For maintaining the validity of the safety guarantees of the pump, only original spare parts from
POMPETRAVAINI must be used. POMPETRAVAINI does not take any responsibility when non-
original spare parts, components, accessories or those not authorized by POMPETRAVAINI are
used on the pump. POMPETRAVAINI does not take any responsibility if any kind of modification
is carried out on the pump, its components and accessories which has not purposely
authorized.
3 – EVENTS OF EMERGENCY
If there is any malfunction on the pump or leakage of liquid conveyed, switch the electric voltage immediately off and
follow the correct procedure for cut-out (see Chapter 11 of the Operator’s Manual). Then inform the personnel
responsible for the plant. At least two persons must act with the necessary attention according to the case, as the pump
may convey dangerous liquids and/or liquids which may be hazardous to persons and to the
environment
.
After having solved all troubles which have generated the emergency, all necessary tests for restarting the electric pump
unit must be carried out (see Chapter 10 of the Operator’s Manual).
