10. Due to the weight, care MUST be taken when installing the analyzer in the rack.
2.2 Gas inputs and outputs
The analyzer has provision for gas input and gas output, both of which are located on the
rear panel of the analyzer (
Figure 2-4 ).
WARNING
HAZARDOUS GAS
The product stream that the analyzer is examining may be hazardous even at low
concentrations. Therefore, take special care to ensure that the sample gas return port
either returns the sample gas to the product stream or discharges the sample gas to a
location that will not cause a hazard.
Procedure
1. The sample supply line provided by the Customer must provide gas at a constant
temperature to the sample gas input port on the analyzer to prevent condensation
forming at any point in the sample supply line within the analyzer, which could
reduce the accuracy of the gas analysis.
2. The gas sample enters the analyzer through the sample gas input port
(C) Figure 2-4 .
3. Once the gas sample passes through the measurement cell and it is expelled from
the analyzer through the sample gas return port (B) Figure 2-4 .
4. The Customer is responsible for ensuring that all expelled gases are disposed of in
accordance with all local and national regulations.
5. Connections for the full rack system where a single gas sample inlet requiring dual
cell analysis or two gas samples requiring separate analysis are shown in Figure 2-4 .
