IMPORTANT SAFETY INSTRUCTIONS:
• This "Instruction manual" has to be kept on the place, which can be easy reached.
• The regulator has to be used only for dry and clean gases. Never use with oxygen: risk of explosion.
• The national norms and standards about installation, start-up and maintenance of the devices and gas installations
have to be strictly respected.
• The handling with the device has to be done carefully, specially by the installation works. The pick up has to be
made by using the stretcher eyes or belts. The device should be examined before the installation for possible
transport damages and be mounted only if it is in perfect state. Possible lacquer damage should be improved. The
sealing surfaces of the threaded connections or flanges must be damage-free and clean.
• For reading off the device and its serving are sufficiently space to designate.
• For the protection of the device is recommendable to install a filter.
• The device is to be installed in such a way that it is not impaired in its function by other installation components.
• The regulator has to be mounted in the pipe line without any tension.
• The mentioned below torque's values for screws must be respected by tighten of the flanged connections:
PN16
ANSI 150
PN25
ANSI 300
• These torque's values are mentioned per screw and are valid for metal soft material gaskets (specified as

• The screws used for the flange connection must be according to the flange size and must be adapted to the tem-
perature range of the regulator. Please tighten the screws crosswise.
• After the installation works are completed, the tightness of the connections (threaded or flanged) must be che-
cked with appropriate means.
• The operating conditions indicated on the name plates must be respected; if necessary appropriate safety de-
vices have to be designated.
• Repairs of the device are allowed to be made only by trained or qualified personal. Afterwards a tightness test
with 11. X PS must be performed. When changing pressure containing parts their compliance with PED must be
assured. After Guarantee only with repair by Actaris.
• The device has to be regularly examined for corrosion danger in the interior and external area and be taken from
use if noticeable corrosion is discovered.
• Gas pressure regulator according to DIN EN 334 - if not equipped, with any electronic device - do not have a potential
ignition source and therefore are not in the scope of European directive 2014/34/EU.
