3.3 Piping
Caution on piping
In piping, the following precautions should be observed.
Wrong piping may cause gas leakage.
If the leaking gas contains a toxic component, there is a risk of
serious accident being induced.
Also, if combustible gas is contained, there is a danger of
explosion, fire or the like occurring.
• Connect pipes correctly referring to the instruction manual.
• Exhaust should be led outdoors so that it will not remain in
the locker and installation room.
• Exhaust from the analyzer should be relieved in the atmo-
spheric air in order that an unnecessary pressure will not be
applied to the analyzer. Otherwise, any pipe in the analyzer
may be disconnected to cause gas leakage.
• For piping, use a pipe and a pressure reducing valve to which
oil and grease are not adhering. If such a material is adhering,
a fire or the like accident may be caused.
