Installation Procedure
Read the Agilent 7697A Headspace Sampler Safety Manual before
upgrading the headspace sampler, and whenever needed. The safety
manual describes precautions to follow when installing 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.
Prepare the GC and 7697A 12-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 all gas flows off at their sources.
4Disconnect the transfer line from the GC inlet. Secure the transfer line
to its support bracket.
5Open the rotating top cover and remove all vials from the carousel.
CAUTION
Wear clean, lint-free gloves to prevent contamination of parts with dirt and skin oils.
CAUTION
Make sure you use an antistatic (ESD) wrist strap and take other antistatic
precautions during the following installation procedures.

Install the 111 vial model oven assembly
1Lower the oven assembly down into the headspace sampler and rest it
on the oven racks so that the carousel motor faces the front as shown
in Figure 17. Lay it closer towards the front than its installation
location to protect your hands from injury while lowering.

the side racks align with the holes in the oven assembly base.
3Install four T- 20 Torx screws at the corners of the oven assembly base
to secure it to the side oven racks and headspace sampler.
WARNING
The oven assembly fits tightly into the headspace oven area. To avoid injury, wear
gloves and be cautious of sharp edges when placing the oven assembly into the
headspace sampler.

6Route the cables from the oven assembly through the opening in the
headspace chassis and to the main board as shown in Figure 20.
Be sure that the cables run cleanly from the oven assembly to the main
board. This will ensure enough cable slack to avoid stress on the main
board connections.
