•
Ensure that the data found on the regulator plate are
compatible with usage requirements.
•
Ensure that the regulator is mounted in accordance with
the direction of flow indicated by the arrow.

WarNING
Installation shall be in accordance with
national standard for material use limita-
tions in gas pressure reducing stations. Only
qualified personnel should install or service
a regulator. regulators should be installed,
operated, and maintained in accordance
with international and applicable codes and
regulations. If the regulator vents fluid or a
leak develops in the system, it indicates that
service is required. Failure to take the regula
-
tor out of service immediately may create a
hazardous condition.
Personal injury, equipment damage, or
leakage due to escaping fluid or bursting of
pressure-containing parts may result if this
regulator is over pressured or is installed
where service conditions could exceed the
limits given in the Characteristics section,
or where conditions exceed any ratings of
the adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting de
-
vices (as required by the appropriate code,
regulation, or standard) to prevent service
conditions from exceeding limits.
additionally, physical damage to the regula-
tor could result in personal injury and prop-
erty damage due to escaping fluid. To avoid
such injury and damage, install the regulator
in a safe location. Before installation, check
shall be done if service conditions are con
-
sistent with use limitations and if pilot set-up
of possible built-in safety shut-off device
are in accordance with service conditions of
protected equipment.
All means for venting have to be provided in
the assemblies where the pressure equip-
ment are installed (ENs 12186 & 12279).
All means for draining have to be provided in
the equipment installed before regulators &
shut-off devices (ENs 12186 & 12279).
Further the ENs 12186 & 12279, where this
product is used :
• provide the cathodic protection and electri
-
cal isolation to avoid any corrosion and
• in accordance with clause 7.3/7.2 of
aforesaid standards, the gas shall be
cleaned by proper filters/separators/
scrubbers to avoid any technical &
reasonable hazard of erosion or abrasion
for pressure containing parts.
Pressure equipment in subject shall be
installed in non-seismic area and hasn’t to
undergo fire and thunderbolt action.
Clean out all pipelines before installation of
the regulator and check to be sure the regu-
lator has not been damaged or has collected
foreign material during shipping.
For threaded bodies, apply pipe compound
to the male pipe threads.
For flanged bodies, use suitable line gaskets
and approved piping and bolting practices.
Install the regulator in any position desired,
unless otherwise specified, but be sure flow
through the body is in the direction indicated
by the arrow on the body.
Installation must be done avoiding anoma
-
lous stresses on the body and using suitable
joint means according equipment dimen-
sions and service conditions.
For a correct and safe use of the connec-
tions check also Instruction manual and Bul-
letin before installation.
user has to check and carry out any protection
suitable for assembly’s specific environment.
Note: It is important that the regulator be
installed so that the vent hole in the spring
case is unobstructed at all times.
For outdoor installations, the regulator
should be located away from vehicular traffic
and positioned so that water, ice, and other
foreign materials cannot enter the spring
case through the vent.
Avoid placing the regulator beneath eaves
or downspouts, and be sure it is above the
probable snow level.
STarTuP
The regulator and/or slam-shut controller is factory set at ap-
proximately the midpoint of the spring range or the pressure
requested, so an initial adjustment may be required to give
the desired results.
With proper installation completed and relief valves properly
adjusted, slowly open the upstream and downstream line
valves.
a. Slightly and very slowly open the outlet cut-off valve.
b. In case of models fitted with slam-shut valve, relatch the
valve by first loosening cap (C) and then screwing it onto
the stem, after which pull cap outwards until a click is
heard, indicating that balls are duly engaged.
c. Slightly and very slowly open the inlet cut-off valve.
d. Wait for outlet pressure to stabilize.
e. Finally, slowly open inlet and outlet cut-off valves fully.
