Side plate
Side plate
The side plate is a flat stainless steel plate that covers the large opening in the side
of the vacuum manifold. The side plate is attached to the manifold with a hinge.
The analyzer assembly is attached to the side plate inside the vacuum manifold.
The hinge allows the side plate to swing away from the manifold for easy access to
the analyzer.
Several electrical feedthroughs are built into the side plate. Wires connect the
feedthroughs to analyzer components. The electronic side board is mounted on
the atmospheric side of the side plate.
Thumbscrews are located at each end of the side plate.

. For normal operation the
both thumbscrews should be loose. For operation with hydrogen carrier gas, or with
flammable or explosive CI reagent gases, the front thumbscrew should be fastened just
finger tight. Overtightening will warp the side plate and cause air leaks.

to tighten the side plate thumbscrews.
