b. Place the jet in the ultrasonic cleaner, filled with liquid detergent.
c.
Sonicate the jet for about five minutes.
d. Handling the jet with forceps or tweezers. Rinse the jet using distilled water, then
methanol.
e.
Place the jet on a paper towel, and let the jet air dry.
f.
Using the proper tool, reinsert and screw the cleaned (or a new) jet into its seat in the
detector body.
11. 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.
12. 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 signal, glow-plug, and polarizing cables.
13. Close the module flap cover.
14. If external modules are present, plug the power cable to the AC Input connector of each
external module, and to the wall outlet.
15. 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.
16. Turn the make-up gas on.
17. Set the normal detector working conditions.
18. Ignite the flame. The fuel gases, hydrogen. and air, are automatically opened.
Note
If after the cleaning physical condition of the jet does not permit its reuse,
replace the jet with a new one.
