Operation and
maintenance note
5.1
Always protect the pressure regulator
from damage (visual inspection at regular
intervals).
The factory settings of the connection
seals must not be changed.
5.2
Ensure that the connector seals, sealing
surfaces and gauges are in perfect con-
dition.
If a fault occurs, for example if the
outlet pressure rises when output = 0,
if there are leaks into the atmosphere,
the guages are defective, or when the
safety valve is activated, shut off the
pressure regulator , close the cylinder
valve immediately.
Air Liquide recommends annual periodic in-
spections of the pressure regulator by compe-
tent, authorized personnel.
Faults that occur can have many causes.
For your own safety, avoid tampering or
making repairs on your own.
6 Repairs
Repairs to the pressure regulators must
only be done by competent and trained
personnel in authorized specialist work-
shops. Only original spare parts must be
used for repairs.
6.1
If unauthorized repairs or changes are
made by the user or a third party without
permission from the manufacturer, then li-
ability for the consequences is rescinded.

Cylinder pressure regula-
tors with flow meter gauge
For these pressure regulators, points 1 to 7
in this operating manual also apply. The flow
quantity set by the pressure adjustment screw
(5) is indicated on the flow meter gauge (4). In
pressure regulators with a flow meter gauge, a
regulating office/ throttle (for pressure control)
(9) is built in. Check if a regulating office/ throt-
tle (for pressure control) is already installed in
your equipment. If yes this must be removed
because the mounting holes are not adapted to
the pressure regulator.
8 Indications to Cylinder
