Important safety instructions:
• Only use for dry and clean gases. For use with aggressive ga-
ses please contact Dresser Actaris Gas for special versions.
Never use with oxygen: Danger of explosion!
• Please respect all national standards and codes of prac-
tices for installation, operation, testing and service of
gas regulators and of gas pressure regulating stations.
• Before mounting please check the regulator for possib-
le 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 pi-
ping.
• 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 con-
taining parts their compliance with the PED must be
assured.
• If used with wet gas, internal and external effect of cor-
rosion 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 adequa-
tely earthed installation.
• For installation, removing or repair of the product on
site, only tools allowed for the corresponding explosion
area can be used.
• The product shall not be exposed to: flames, ionised ra-
diation and ultrasound.
• Ambient temp. conditions must be considered, inclu-
ding possible additional heating effects due to other
devices in immediate vicinity.
• Gas pressure regulator according to DIN EN 334 - if not
equipped, with any electronic device - do not have a po-
tential ignition sourse and therefore are not in the scope
of European directive 2014/34/EU.
