This contains procedures that might need to be performed on rare occasions when
a major component of the analyzer requires repair or replacement.
The critical flow orifice is housed in the flow control assembly (Teledyne API PN
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 PNs and kits):
1. Turn off power to the analyzer.
2. Locate the assembly attached to the sample pump, see Figure 3-5.
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
below.
5. Replace the o-rings (PN OR000001) and the sintered filter (PN FL000001).
6. If replacing the critical flow orifice itself (PN 000940700), make sure that the
side with the colored window (usually red) is facing upstream to the flow gas
flow.
