4.1 Transport, storage and handling
 Transport, storage and handling operations must be carried out by qualified personnel, using
appropriate facilities.
 These pressure regulators must be transported and stored in their original packaging; any
deterioration of the packaging can affect the operation or the safety of the product.
 These pressure regulators must be stored in a room protected from dust and humidity, at a
temperature of between -40 and +70 °C; do not subject the unprotected pressure regulator to harsh
weather conditions.
 Never transport the cylinder carrying it by the valve or by the pressure regulator assembly.
 Always remove the pressure regulator from the cylinder for transport, when not in use.
 Keep out of the reach of children.
4.2 Routine checks
 The pressure regulators are supplied bare, without their inlet and outlet adapters installed.
 When unpacking or installing the pressure regulator, make sure that there are no anomalies (all
items present, correct condition of the indicators, appropriate connectors, etc.).
 The pressure regulators must not be subjected to any violent shocks: a damaged pressure regulator
must not be used. In such cases, have the unit overhauled.
 Only use equipment which is in perfect condition, and ensure that it is compatible with the type of
gas used, and with the required pressures and flow-rates.
 Observe the cleanness of the unit during handling (no dust, water or grease, etc.), and of the
accessories to which it is connected.
 The pressure regulator is designed to be associated with other accessories. The assembly of such
accessories onto the pressure regulator shall be carried out by qualified personnel.
