3.1 - GENERAL SAFETY WARNINGS
WARNING!
The equipment described in this instruction manual is:
• a device subjected to pressure in pressurised systems;
• normally installed in systems carrying ammable gases (for example: natural gas).
WARNING!
If the gas used is a combustible gas, the installation area of the equipment is dened as a “danger zone”
as there are residual risks that potentially explosive atmospheres may be generated.
In “danger zones” and in close proximity thereto:
• there must not be any effective sources of ignition;
• no smoking.
WARNING!
• It is strictly forbidden to repair or make any modications to the equipment.
• For information and warnings concerning the maintenance of the equipment, please refer to Chapter 9
