1.1 Safety
First of all, it is ESSENTIAL to read and respect the
safety instructions described in the document
“General Safety Instructions” delivered with the
product.
For safety reasons the inlet fitting and the seal of
the flexible hose are specific to a gas or a mixture
family, they are so designed to avoid any connec-
tion mistake.
NEVER use the flexible hose for an application or
a gas different than the one for which it is intend-
ed.
• During operation, ensure the anti-whip safety
cable has been securely fixed at its two extrem-
ities.
• During operation, ensure the anti-whip safety
cable has been securely fixed at its two extrem-
ities.
• Before connecting the flexible hose to avoid any
risk of falling cylinders etc., ensure that:
- Cylinders are well attached,
- Bundles are well settled on a plane and hori-
zontal surface,
- The location of the cylinders is sufficiently
well ventilated.
NEVER dismantle a flexible hose if:
• The cylinder or bundle valve is not closed,
• The flexible hose is under pressure.
NEVER tighten or loosen a connection under
pressure.
NEVER connect two flexible hoses together.
In each case slowly open and close cylinder valve.
Never attempt to repair a flexible hose. In case of
problem, close the cylinder valve fully, purge the
flexible hose and proceed to replace with a new
flexible hose.
1.2 Air Liquide commitments
Air Liquide certifies that the equipment is manu-
factured, tested and controlled, in accordance

1.4 REACH regulation (EC)
n°1907/2006
Equipment from Air Liquide can be made of brass
components, which is a copper alloy with a lead
content between 1 % and 4 % w/w. As requested
by art. 33 of REACH Regulation (Registration,
Evaluation and Authorisation of Chemicals) and
with reference to current list of SVHC (substances
of very high concern) available on ECHA website,
we inform that lead may be present in a concentra-
tion above 0,1% w/w in our products made of
brass.
Lead inclusion in the SVHC list in June 2018 does
not modify the use conditions described in operat-
ing instructions.
Lead will not be released to the surrounding envi-
ronment or the gas used during normal use.
After product end of life, the pressure reducers
must be scrapped by an authorized metal recycler.
