8. Remove the Fibre Optic Cables from both ends of the measurement cell. Carefully
hang the cables in a location where the ends of the cables cannot not contact anything.
Cap the ends of the two fibres with the orange protective caps.
9. Loosen one of the cell tubing fittings to vent positive pressure zero gas that may be
trapped in the sample system.
10. To remove the measurement cell block, tubing connected to the measurement cell
block assembly must first be removed. Disconnect the fittings circled in Figure 78.

11. Using a 7/64” ball driver, remove the 6-32 x 3/8” screw securing the cell RTD to the
cell block Carefully place the cell RTD behind the cell block where it will be out of the
way.
12. Loosen the four ¼-20 x 2” mounting screws from the cell block face using a 3/16” ball
driver. Before removing the last screw entirely, place your fingers under the cell block
to support the cell block as you release the last screw.
13. Carefully remove the measurement cell block from the analyzer. Disconnect any
additional tubing as required to remove the measurement cell block, bearing in mind
the warning displayed in Figure 78.
Process gas is still present at
the probe side of these
valves. To prevent the
release of toxic gases, ONLY
disconnect tubing from the
cell side of these valves, NOT
the probe side.
