3.3 Piping
Observe the following when connecting the gas pipes.
• The pipes should be connected to the gas inlet and outlet at the rear panel of the analyzer,
respectively.
• Connect the sampling system to the instrument by using corrosion-resistant tube such as teflon,
stainless steel, or polyethylene. In case where there is no danger of corrosion, don't use rubber
or soft vinyl tube. Analyzer indication may become inaccurate due to the adsorption of gases.
• Piping connections are female-threaded. Cut the pipe as short as possible for quick response.
Pipe of ø 4mm (inside dianeter) is recommendable .
• If dust or gas with high water content enter into the instrument, malfunction may result.
To prevent this, be sure to use clean pipes and joints.
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 atmospheric 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.
