Repositioning the Lens Housing

bly from the hood.
2. Loosen the two lens retaining ring
screws on the facepiece.
3. Remove the lens retaining rings
and the lens housing assembly
from the facepiece.
4. Reverse the lens housing assembly
so that the door hinge is at the top.
5. Re-install the lens retaining rings
and screws.

ACCESSORIES
Nosecup
The nosecup is used with the Ultravue
(full) facepiece to reduce lens fogging
caused by high humidity or tempera-
tures below 32°F. Nosecups are avail-
able in small (P/N 471710), medium
(P/N 471711), or large (P/N 471712).
To install the nosecup:
1. Place the nosecup in the face-
piece and position it so its rubber
ring faces toward the plastic
retainer ring.
2. Starting at the top, stretch and
push the rubber ring of the nose-
cup under the plastic retainer ring
of the speaking diaphragm
assembly.
3. Continue stretching the nosecup
ring and work it into place.
Spectacle Kit (P/N 454819)
The spectacle kit is designed to be
used by people who wear glasses.
The temple bars of conventional
glasses stick through the sealing edge
of a full facepiece and prevent a prop-
er seal. The kit includes the support
assembly, a rubber block, and the
spectacle frame. Prescription lenses
can be obtained locally or through
MSA. To install the kit:
1. Hold the support assembly so that
the “coated” arms are up and the
rubber block is toward the face-
piece lens.
2. Squeeze the arms together and
insert the assembly into the face-
piece.
