Installation Steps
3.8 Final Analyzer Connections
Note
In some situations when using Hydrogen carrier, the carrier connection will not be made directly
to the ports on the side of the analyzer. Depending on customer options, the connection may
be to an external pressure switch. This switch, if used, will be mounted externally on the Maxum
analyzer and will be labeled "HYDROGEN".
Explosion risk
To prevent dangerous conditions to life always shut off the flow of gas utilities when the air
supply is not present to reduce consumption and the possibility of flammable gas collecting in
the oven and or sample system.
● The analyzer oven exhaust vent(s) should be routed outside the building or shelter. See the
above warning concerning vent lines.
● Remove the plugs from the sample supply lines. If Siemens is supplying the sampling
system, the sample conditioning portion will probably be mounted in a cabinet or on a panel
beneath the analyzer oven. Connect the sample supply lines to the port labeled by their
stream numbers on the side of the cabinet or on the panel; see the Application Drawing
Package, Sampling System Connections sheet.
● Remove the plug from the calibration-standard supply line. Connect the line to the correct
calibration standard port; see the Application Drawing Package, Sampling System
Connections sheet.
● Connect drain, or return lines, as required to the appropriate sampling system vent. See the
Application Drawing Package, Sampling System Connections sheet.
