Figure 29: Replacing the Channel-End Seals
The manifold end plate sits in front of the manifold and holds the
screws, washers, and springs that hold the manifold in place. The
channel-end seals sit in bored holes in the backside of the plate, facing
the manifold’s channels. The manifold end plate has markings to
indicate its position relative to the manifold, e.g., Top or Bottom.
2. Using an appropriate tool, such as a very small, flat screwdriver or a
paper clip, remove the seals from the manifold end plate.
Caution: Do not grease any parts of this mechanism.
Lubricate the seals and the bored holes with alcohol to
assist with reinsertion.
3. Clean the seals if you are not replacing them with new ones.
4.
Lubricate both the seals and the bored holes with 70% isopropyl alcohol
to facilitate insertion of the seals. Make sure the seals sit firmly in the
bored holes in the manifold end plate.
The 9/64
”
(3.57 mm) hex wrench shipped with the washer is
useful for reinserting the seals into the bored holes.
5. When all of the seals are in place, reinstall the manifold end plates and
the manifold.
Do not overtighten the manifold screws .
Caution: When reinstalling the manifold, only tighten the
screw-washer-spring assembly that holds it in place until
you feel the mechanical stop. You will damage the
instrument if you continue tightening past this point.
