f. Place the collecting electrode on a paper towel and let it air dry.
Note If after the cleaning the physical condition of the collecting electrode does
not permit its reuse, replace the electrode with a new one.
g. Place the cleaned (or a new) collecting electrode and the insulator ring in its housing.
11. Reinstall the top parts of the detector.
a. Remount the cell top cover, then screw the detector cap, paying attention to not
rotate the cell top cover.
b. Reconnect the signal, glow-plug, and polarizing cables.
12. Close the module flap cover.
13. If external modules are present, plug the power cable to the AC Input connector of each
external module, and to the wall outlet.
14. 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.
15. Set the make-up gas on.
16. Set the normal detector working conditions.
17. Ignite the flame.
 To replace the ignition glow-plug
1. Put the GC in standby condition.
2. Turn the flame off. The fuel gases, hydrogen and air, are automatically closed.
3. Cool the detector to room temperature.
4. Turn the make-up gas off.
Note By pressing the Maintenance button, the GC cool down is automatically
carried out.
5. 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.
