Safety Instructions and EU Declaration of Conformity:
• 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 mount-
ed 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 (property class 5.6) must be respected by tighten of
the flanged connections:
• These torque‘s values are mentioned per screw and are valid for metal soft material gaskets
(specified as k0xKD=45bD und k1=2,2bD). Other gaskets can require another torque‘s values.
• The screws used for the flange connection must be according to the flange size and must be adapted
to the temperature 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 checked with appropriate means.
• The operating conditions indicated on the name plates must be respected; if necessary appropriate
safety devices have to be designated.
• Repairs of the device are allowed to be made only by trained or qualified personal. Afterwards a tight-
ness test with 1.1 X PS must be performed. When changing pressure containing parts their compli-
ance with PED must be assured. After guarantee only with repair by Itron.
• 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.
• The inner chamber volume of the RR 16 regulator amounts to::
• The cleaning of the devices has to be done without using any alcohol containing solvent or cleaning
agents.
• The device is not appropriate for floods and loads by earthquakes.
• The pressure has to be completely discharged before to take the device from the pipe line. The rest
of gas can withdraw; therefore the required ventilation has to be insured.
• The appropriate measures for noise reduction have to be seized depending on the installation place
and work conditions.
