c. Turn the hydrogen flow Off.
d. Turn the Air supply On.
i. Measure the gas flow and verify that the actual flow rate corresponds to the
setpoint value.
e. Turn the Air flow Off.
f. Turn the Makeup gas flow On.
i. Measure the gas flow and verify that the actual flow rate corresponds to the
setpoint value.
g. Turn the Makeup Off.
14. Power off the GC.
a. Push down the power switch (breaker), located at the back of the instrument, to the
position O.
b. Unplug the power cable from the AC Input connector into the back of the GC, and
from the wall outlet.
15. Unscrew the detector cap, then remove the measuring tool from the detector body.
16. Reinstall the electrodes.
a. Reinsert the polarizing electrode into its seat pushing while screwing it, then screw
the fixing screw.
b. Remount the collector insulator, the collecting electrode, and its insulator ring.
17. Remount the top parts of the detector.
a. Remount the cell top cover.
b. Screw the detector cap paying attention to not rotate the cell top cover.
c. Reconnect the signal, glow-plug, and polarizing cables.
18. Close the module flap cover.
19. If external modules are present, plug the power cable to the AC Input connector of each
external module, and to the wall outlet.
20. Power on the GC.
a. Plug the power cable to the AC Input connector into the back of the GC and to the
wall outlet.
b. Flip up the power switch (breaker) to the position I.
21. Turn the make-up gas on.
22. Set the normal oven and detector working conditions.
23. Ignite the flame. The fuel gases, hydrogen and air, are automatically opened.
