INSTALLATION
a. Check that data on the pilot’s plate are compatible with
actual working conditions.
b. Install in accordance with regulator instruction manual.
STARTUP
See the set-up and pilot adjustment instructions applying to
the equipment where the pilot is tted.
PERIODIC CHECKS
Slowly close the outlet slam-shut and check line pressure
between it and regulator.
A slight increase in pressure should be detected: this results
from overload due to closing, and is followed by pressure stabi-
lization. If outlet pressure continues to rise, then seal is defec-
tive. Check if leak is coming from regulator or pilot, and service.
SEP STATEMENT
Emerson Process declares this product conforms to
Pressure Equipment Directive (PED) 97/23/EC.
Article 3 section 3 and was designed and manufactured in
accordance with sound engineering practice (SEP).
Per Article 3 section 3, this “SEP” product must not bear the
CE marking.
ATEX REQUIREMENTS
!
WARNING
If the provisions of EN 12186 & EN 12279,
nationalregulations,ifany,andspecic
manufacturer recommendations are not
put into practice before installation and
if purge by inert gas is not carried out
before equipment’s start-up and shut-down
operations, a potential external and internal
explosive atmosphere can be present in
equipment & gas pressure regulating/
measuring stations/installations.
If a presence of foreign material in the pipelines is foreseen
and purge by inert gas is not carried out, the following
procedure is recommended to avoid any possible external
ignition source inside the equipment due to mechanical
generated sparks:
drainage to safe area via drain lines of foreign materials, if •
any, by inow of fuel gas with low velocity in the pipe-work
(5m/sec)
In any case,
provisions of Directive 1999/92/EC and 89/655/EC shall •
be enforced by gas pressure regulating/measuring station/
installation’s end user
with a view to preventing and providing protection against •
explosions, technical and/or organizational measures
appropriate to the nature of the operation shall be taken
(e.g. : lling/exhausting of fuel gas of internal volume
of the isolated part/entire installation with vent lines
to safe area - 7.5.2 of EN 12186 & 7.4 of EN 12279 ;
monitoring of settings with further exhaust of fuel gas to
safe area ; connection of isolated part/entire installation to
downstream pipeline; ….)
provision in 9.3 of EN 12186 & 12279 shall be enforced •
by pressure regulating/measuring station/installation’s end
user
external tightness test shall be carried out after each •
reassembly at installation site using testing pressure in
accordance with national rules
periodical check/maintenance for surveillance shall be •
carried out complying with national regulations, if any, and
specic manufacturer recommendations.
