Getting Started Model GFC7000TA Carbon Dioxide Analyzer

3.6.1. Basic Pneumatic Connections

NOTE

In order to prevent dust from getting into the gas flow channels of your analyzer, it was shipped with small plugs inserted into each of the pneumatic fittings on the back panel. Remove these plugs before operating the analyzer. It is recommended that they be stored for future use (moving, storing or shipping the analyzer).

Figure 3-4 illustrates the basic configuration for gas supply and exhaust lines to the Model GFC 7000TA Analyzer. Figure 3-5 illustrates the internal gas flow of the instrument in its basic configuration.

Please refer to Figure 3-2 for pneumatic connections at the rear panel and Table 3-2 for description.

NOTE

Sample and calibration gases should only come into contact with PTFE (Teflon),

FEP, glass, stainless steel or brass.
