Safety Instructions And Eu Declaration Of Conformity - Dresser Rr 16 Bedienungsanleitung

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

PN 16
ANSI 150
• These torque's values are mentioned per screw and are valid for metal soft material gaskets (speci-
fied 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
