Model GFC7000TA Carbon Dioxide Analyzer

10.6. Repair Procedures

This contains procedures that might need to be performed on rare occasions when a major component of the analyzer requires repair or replacement.

10.6.1. Repairing Sample Flow Control Assembly

The critical flow orifice is housed in the flow control assembly (Teledyne Instruments part number: 001760400) located on the top of the optical bench. A sintered filter protects the jewel orifice so it is unusual for the orifice to need replacing, but if it does, or the filter needs replacement please use the following procedure (see the Spare Parts list in Appendix B for part numbers and kits):

1.Turn off power to the analyzer.

2.Locate the assembly attached to the sample pump, see Figure 3–3.

3.Disconnect the pneumatic connection from the flow assembly and the assembly from the pump.

4.Remove the fitting and the components as shown in the exploded view in Figure 11.6.

5.Replace the o-rings (p/n OR000001) and the sintered filter (p/n FL000001).

6.If replacing the critical flow orifice itself (P/N 00094100), make sure that the side with the colored window (usually red) is facing upstream to the flow gas flow.

7.Apply new Teflon® tape to the male connector threads

8.Re-assemble in reverse order.

9.After reconnecting the power and pneumatic lines, flow check the instrument as described in Section 9.3.4.
