Important Safety Instructions - ITRON RB 4000 Instruction Manual

Keep this manual easily accessible for all users.

IMPORTANT SAFETY INSTRUCTIONS:

» Only use for dry and clean gases. For use with aggressive
gases please contact ITRON for special versions.
For applications with Hydrogen, after maintenance, purge the
device with inert gas like nitrogen.
Never use with oxygen: Danger of explosion!
» Please respect all national standards and codes of practices
for installation, operation, testing and service of gas regulators
and of gas pressure regulating stations.
» Before mounting please check the regulator for possible
damage due to transport. The sealing surfaces must be clean.
» Arrange enough room for the serving of the regulator.
» To protect the regulator from dirt a sieve or a filter is
recommended.
» The regulator must be installed tension free in the piping.
» After installation please check the tightness of the thread
connection.
» The technical data given on the name plate must be respected.
If necessary safety devices must be installed.
» Repairs and maintenance must be done by trained or qualified
personal. Only use original spare parts from Itron. Afterwards
a tightness test with 1.1 x PS must be performed. When
changing pressure containing parts their compliance with the
PED must be assured.
» If used with wet gas, internal and external effect of corrosion
has to be checked regularly and in case of severe corrosion,
the regulator has to be replaced.
» The device must be cleaned with a wet cloth only.
Please don't use solvent or alcohol containing products to
clean the regulator.
» Before removing the regulator please depressurise completely.
Some gas may still be inside the regulator and the pipe,
therefore sufficient ventilation is required.

REMARKS FOR USE IN POTENTIALLY
EXPLOSIVE ATMOSPHERES (ATEX):
» If film of rust is possible (flying rust in the immediate regulator
surroundings), all outer aluminium parts have to be protected
accordingly (e.g. by varnish).
» The product must be electrically connected to adequately
earthed installation.
» For installation, removing or repair of the regulator on site, only
tools allowed for the corresponding explosion area can be
used.
» The regulator shall not be exposed to: flames, ionised radiation
and ultrasound.
» Ambient temp. conditions must be considered, including
possible additional heating effects due to other devices in
immediate vicinity.
The RB 4000 pressure regulator is designed for gas supply
networks, district station regulation, industrial service regulation,
and all applications where accurate pressure control, ease of
adjustment, and fast response are required such as for burners,
industrial ovens, boilers, etc.
It may be fitted with an integrated safety shut-off device type SSV
8500 or SSV 8600.
