Installation
Read the Agilent 7697A Headspace Sampler Safety Manual before installing
the cooling plate accessory, and whenever needed. The safety manual
describes precautions to follow when performing maintenance and using
the headspace sampler, as well as important regulatory information.
Confirm that all parts have been received. Refer to “Parts Supplied” and
“Parts Identification” for information.
To prepare the GC and 7697A 111-Vial Headspace Sampler
1Set your GC oven, GC inlet, headspace oven, and transfer line to
ambient temperatures and wait for them to cool.
2Once the GC oven, headspace oven, and transfer line have cooled to
ambient temperature, turn off the headspace and unplug the power
cord.
3Turn off all gas flows at their sources.
4Remove all sample vials and vial racks from the headspace tray area.
CAUTION
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.

3Lift the tray assembly off of the headspace and place it aside on a flat
surface.
4Using a T- 20 Torx driver, remove the six screws that secure the top
tray base plate to the headspace (Figure 6), then lift the top tray base
plate from the headspace.

5Disconnect the three cables from the wire harness on the underside of
the top tray base plate (Figure 7).
6Remove the top tray base plate from the headspace.
To install the G4565A Cooling Plate Accessory
1Install the new top base plate.
aConnect the three cables to the wire harness on the underside of the
top cooling accessory base plate.
bInstall six T- 20 screws to secure the top cooling accessory base plate
to the headspace chassis.
Figure 8 shows the new top base plate installed on the headspace.

2Install the secondary drip tray on the right side of the base plate.
Align the hole in the base plate with the knob on the secondary drip
tray (Figure 9).
3On the underside of the cooling plate assembly, check that all plastic
wrapping is intact, especially for the three LED electronics boards on
the underside of the front edge (see Figure 10).

CAUTION
Moisture-sensitive components on the cooling plate assembly are wrapped in
plastic. Do not remove the wrapping. Removing the wrapping will result in
premature failure of the electronic components.

4Lower the back of the cooling plate assembly onto the top instrument
cover while holding the front of the assembly above the headspace.
5Slide the cables into the plate cable clip (Figure 11).
6Connect the cooling plate cables to the cable connections (Figure 12).
7Lower the front of the cooling plate assembly onto the headspace. Be
sure it sits level on the headspace sampler.
8Install the metal vial rack assemblies. Take note of the vial position
numbering on the top of vial racks when placing them into the cooling
plate assembly.

9Install the cooler drip tube to the back of the headspace.
aInstall the clamp onto the tube end.
bInstall the clamp and tube into the fitting shown in Figure 13.
10 Cut the cooler drip tube to length. The tube must allow for
condensate to drain easily with no back pressure. Otherwise, water
will not drain properly. See “Periodic Maintenance” on page 16 for
information about the drip tube.
11 Remove the orange shipping clamp from the cooling plate gantry using
a T- 20 Torx driver. Refer to the instruction sheet provided with the
cooling plate.
12 Plug in the headspace power cord, and restore the headspace and GC to
operating conditions.
