IMPORTANT SAFETY INSTRUCTIONS:
» Only use for dry and clean gases. For use with aggressive
gases please contact ITRON for special versions.
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. 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.
