 To add the hydrogen sensor
WARNING This operation must be carried out by authorized and trained Thermo Fisher
Scientific Service Field Engineers.
1. Put the GC in standby condition.
2. Cool the oven, injectors and detectors to room temperature.
3. Close the gas supplies.
4. 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.
5. If external modules are present, unplug the power cable from the AC Input connector of
each external module, and from the wall outlet.
6. Remove the left side panel.
a. Open the front door of the GC.
b. Using a T20 Torxhead screwdriver, unscrew the left side panel screw from the interior
front panel. Save the screw because it will be reused later.
c. Slide the panel towards the back of the instrument up to the stop.
d. Remove the panel by pulling it outward. Be aware that the ground wire is attached to
the panel.
e. Unplug the ground wire from the panel.
7. Remove the back cover.
a. Use a T20 Torxhead screwdriver to remove the four screws that secure the back cover
to the GC.
b. Lift the cover off using the cover handle. Be aware that the ground wire is attached to
the back panel.
Note Pay attention to the positioning of the ground wire plug, so it can be reconnected in
the same way it was removed.
8. Perforate the duct for the installation of the sensor into the oven.
a. Looking the interior of the GC from the back side, locate the duct provided on the
back wall of the oven. See Figure 601.
