for:
The equipment referred to was designed to be used exclusively within the limits specified on the nameplate and according
to the instructions and limits of use specified in this manual.
Safe work conditions are as follows:

4.3.2 - REASONABLY FORESEEABLE MISUSE

Incorrect and reasonably foreseeable use means the use of the equipment in a way not foreseen in the phase
but which can derive from easily predictable human behaviour:
• corrosive fluids;
• fluids not properly treated upstream;
• liquids;
• instinctive reaction of an operator in the event of a malfunction, accident or breakdown while using the equipment;
• behaviour resulting from pressure to keep the equipment running under all circumstances;
• behaviour resulting from carelessness;
• behaviour resulting from the use of the equipment by unauthorised and unsuitable people (children, disabled);
• using the equipment in a manner other than that referred to under "Intended use".
