• rising pillars;
• burners.
The equipment in question is intended for:
Operation Permitted Unpermitted Work environment
Adjustment of the
downstream pressure
for:
Gaseous, and non-aggres-
sive or corrosive uids l-
tered beforehand.
• Liquids.
• Any product other than
those permitted.
Installations for the distribution
of natural gas to supply net-

• compliance with the operating and warning instructions as well as commissioning procedures (refer to chapter 8);
• do not tamper with and/or bypass the safety devices.
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 uids;
• uids 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”.
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 UNI EN 12186:2014 and UNI EN 12279:2007 standards, or in installations
carrying LPG;
• in commercial premises and industrial plants (after checking by contacting PIETRO FIORENTINI S.p.A.).
NOTE!
The equipment may be also used with inert gases, subject to verication by contacting the manufacturer.
