ULTRA ELITE FACEPIECE
REMOVING THE COMPONENT HOUSING ASSEMBLY
Note: Remove the adapter assembly and the component
housing cover.
1. Use a small phillips screwdriver to remove the compo-
nent housing ring screw.
2. Grasp the ring with the
thumb and forefinger of
each hand. Gently
spread the ring halves
apart at the bottom.
3. When the facepiece
rubber is out of the ring
groove, lift the ring up
away from the face-
piece. You may need to
pull the housing down
slightly to allow enough
room to remove the
ring from between the
housing and the lower
lens ring.
4. Remove the facepiece rubber from the component
housing and pull the housing and nosecup (if installed)
out of the facepiece.
INSTALLING THE COMPONENT HOUSING ASSEMBLY
1. Slide the housing into the front of the facepiece.
2. Starting at the top
(narrow end) of the
housing, place the
housing in the face-
piece groove. Work the
rubber all the way
around the housing.
Check that the housing
is completely captured
inside the groove and
the center-lines are
lined up.
3. Moisten the facepiece housing area and the inside of
the housing ring.
4. Insert the narrow end of the ring into the space
between the lower lens ring and the facepiece housing
area.
5. Line up the component
housing ring mark with
the facepiece center-
line.
6. Starting at the top,
work the housing ring
down on the facepiece
to capture the face-
piece rubber in the ring
groove. Work your way
down each side of the
ring until the facepiece
rubber is completely
captured inside the
ring.
7. Gently squeeze the ring halves together at the bottom
of the housing. Watch the facepiece rubber at the top
as you do this. If you see any bulges or wrinkles in the
facepiece rubber, it is not captured in the groove.
Rework the ring around the facepiece rubber until
there are no bulges or wrinkles.
Bulges or wrinkles mean that the facepiece rubber is
not seated correctly in the ring. Re-install the ring to
seat it correctly. Failure to follow this warning can
cause the facepiece to leak and result in serious per-
sonal injury or death.
8. When the housing ring appears to be seated, grasp
the outside of the ring and the inside of the housing at
the top between your thumb and forefinger and
squeeze them together. Then do the same with the
ring halves at the bottom.
