3.1 Control at Delivery
When you receive the G4100 NOX/O2Analyzing System, please inspect and confirm that
the received items are in accordance with the packing list and not damaged. Any discrep-
ancy should be reported to the supplier immediately. If any of the received parts are dam-
aged, the shipping company should be informed, and new parts should be made available
before completing the installation.
3.2 Where to Install the System
Satisfactory operation, faultless functions, and minimal maintenance of the G4100 NOX/O2
Analyzing System are achieved by paying attention to the following points:
•Make sure to install the ejector probe in a suitable location where it will extract the
gas that is going to be tested.
•The ejector probe shall be fitted at least 10 pipe diameters after the outlet of the en-
gine, the turbocharger, or the last after-treatment device –choose whichever is further
downstream. However, the ejector probe shall also be placed at least 0.5 m or 3 pipe di-
ameters upstream from the exit of the exhaust gas system –choose what provides the
greatest length. See 107H25H25HFigure 3-1 for the installation layout of the ejector probe. If you find
it difficult estimating where to install the ejector probe, please contact Green Instruments
A/S for more instructions.
•As a standard scope of supply, the analyzing board can be installed up to 3 m from
the ejector probe. If necessary, the umbilical cord can be extended.
•The analyzing board shall be placed and installed where the ambient temperature is
below 55 C at any time.
•The system shall be installed in a clean place away from dust, oil mist, and mois-
ture. The elements of the system shall be installed at viewing level so that it is easy ac-
cessible in connection with operation and service.
