4. Grasp the entire valve assembly firmly and pull it away from the
Analyzer with a slight rocking motion until it is free of the
mounting guide.
NOTE: If the O-ring, and/or plastic bushing are accidentally
removed with the shear valve, replace them at this time. Place
the bushing on the mounting guide with the curved inner surface
facing the rear of the instrument and slide it back as far as it will
go. Slide the O-ring back on the mounting guide until it is
against the flat inner surface of the bushing.
5. Rotate the center and front sections in the opposite direction from
the rear section to release any suction and free the rear section.
CAUTION: Be careful to keep a firm grip on the center section,
as it is not attached to the front or back sections and it may break
or crack if dropped.
6. Place the rear section with its attached tubes on a clean wipe in the
shear valve compartment.
7. Rotate the center and front sections in opposite directions to
separate them.
8. Place the center section in a container of warm water and allow it to
soak for the remainder of the cleaning procedure.
CAUTION: Do not soak the center section in bleach as it may
damage the ceramic.
9. Place the front section with its attached tubes on a clean wipe in the
shear valve compartment.
10. Clean the mounting guide with lint-free wipes dampened with
warm water to remove any blood or residue. Dry the guide.
11. Wipe the inner surfaces of the front and rear sections with a clean
nonabrasive wipe dampened with warm water. Use care to avoid
scratching any of the inner surfaces. Wipe the surfaces dry with a
lint-free wipe.
NOTE: Hold the sections by the edges to avoid getting
fingerprints on the inner surfaces.
12. Remove the center section from the warm water, wipe the surfaces
with a nonabrasive wipe dampened in warm water and dry it with a
lint-free wipe.
