the speech diaphragm housing and insert the speech
diaphragm assembly into the larger port of the lens so the
keys in the port line up with the notches in the housing,
and the O-ring is between the inside of the lens and the
speech diaphragm housing. When inserted properly the
threads of the housing will be completely through the lens
and the housing will be flush up against the inside of the
lens.
g. Insert the outer nut (P/N 80862-H5) onto the housing
threads and hand-tighten by turning clockwise.
h. Put the remaining inhalation valves (P/N 770017) on the
valve seats (P/N 80814A) for the oral/nasal cup (P/N
80815-H5 for medium/large or 80800-H5 for small)
making sure they lie flat against the seats. Insert the
seat and inhalation valve assembly into the oral/nasal
cup.
i. Position the oral/nasal cup by first pulling the lower flange
on the cup through the small port on the lens so it lies
flush with the lens. Straighten the cup by turning it so the
peak of the nasal area is on top. Work larger opening of
the cup into groove of the speech diaphragm housing that
is furthest from the lens.
j. Insert the exhalation valve (P/N 770018) into the
exhalation valve seat (P/N 80862-H5) and pull in the tab
until you hear a “click”. When inserted correctly the flat
end of the exhalation valve will be on the thread side of
the seat and sit flush with the seat.
k. Push the exhalation valve assembly through the lower
opening of the oral/nasal cup that is now assembled onto
the facepiece. You may need to use a slight pressure
to push the assembly completely through. Insert the
exhalation housing guard (P/N 80867-H5) onto the
housing threads and hand-tighten by turning clockwise.
