REDLINE® C 300 cylinder regulators
4. Installation instructions and handling
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 them out of the reach of children.
• 4.2 Routine checks
• 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 or replaced.
• Only use equipment which is in perfect
conditions, and ensure that it is compatible
with the type of fluid used (gas or liquid), 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.
4.3 Installation of the pressure regulator
• Ensure your hands are clean before installing
or handling the pressure regulator.
• Install the outlet union.
• Connect the pressure regulator to the
utilisation system.
• Unscrew the hand wheel of the pressure
regulator and check that the downstream
system is closed.
• Slowly open the shut-off valve. Check the
pressure on the supply pressure indicator.
• Slowly screw in the hand wheel of the
pressure regulator until a flow is obtained.
• Check the sealing of the complete assembly,
particularly the adapters. CAUTION: Never
attempt to tighten a union which is under fluid
pressure.
• Close the supply valve. Bleed the unit.
Unscrew the hand wheel of the pressure
regulator.
4.4 Use of the pressure regulator
• Check that the hand wheel of the pressure
regulator is unscrewed.
• Slowly open the shut-off valve. Check the
pressure on the supply pressure indicator.
• Screw the hand wheel of the pressure
regulator until the required pressure is
obtained - check that gas issues from the unit.
• After use, close the supply valve, wait until
gas no longer issues from the unit and then
unscrew the hand wheel of the pressure
regulator.
