for:
Gaseous, and non-corro-
sive, fluids that have been
filtered beforehand.
• Liquids.

The equipment in question is used as a main regulator and in-line monitor regulator.
It was designed to be used exclusively within the limits specified on the nameplate and according to the instructions and
limits of use referred to in this manual.

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;
• using the equipment in a manner other than that referred to under “Intended use”.
Any use of the equipment other than the intended use must be previously approved in writing by PIETRO FIORENTINI S.P.A.
If no written approval is provided, use shall be considered improper.
In the event of “improper use”, PIETRO FIORENTINI S.P.A. shall not be held liable for any damage caused to people or
property, and any type of warranty on the equipment shall be deemed void.
4.3.3 - TYPES OF FLUIDS
The equipment works with combustible gases used:
• in pressure control stations according to EN 12186 or EN 12279;
• in transmission and distribution networks.
• in commercial and industrial plants (after checking by contacting the Manufacturer).
NOTICE!
The equipment may be also used with inert gases, subject to verification by contacting the manufacturer.
