ULTRA ELITE FACEPIECE
CLEANING AND DISINFECTING
Depending on the cleaning policy adopted, either a desig-
nated person or the user should clean each device after
each use. ANSI standards suggest that users should be
trained in the cleaning procedure. Confidence Plus
Cleaning Solution (P/N 10009971) from MSA is recom-
mended. It cleans and disinfects in one operation. It
retains its germicidal efficiency in hard water to inhibit the
growth of bacteria. It will not deteriorate rubber, plastic,
glass, or metal parts. Refer to label for user instructions.
• DO NOT use any cleaning substances that can or
might attack any part of the apparatus.
• Alcohol should not be used as a germicide
because it may deteriorate rubber parts.
• If not rinsed thoroughly, cleaning agent residue
may irritate the wearer’s skin.
1. Preparing Solution
a. Follow the instructions with the Confidence Plus
Cleaning Solution.
b. If the Confidence Plus Cleaning Solution is not
used, wash in a mild cleaning solution, rinse thor-
oughly, and submerge in a germicide solution for
the manufacturer’s recommended time.
2. Clean and Disinfect the Facepiece
a. Remove the mask mounted regulator from the face-
piece.
b. Unthread the thumb screw of NightFighter Heads-
Up Display System receiver Voicemitter Assembly,
slide the receiver from facepiece bracket.
c. Thoroughly wash the facepiece (and nosecup) in the
cleaning solution. A soft brush or sponge can be
used to clean the soiled facepiece.
d. Rinse the facepiece and components in clean,
warm (110°F) water (preferably running and
drained).
e. Clean the pressure-demand exhalation valve by
pressing in on the stem with a blunt object and
flushing with clean water.
f. Allow the facepiece to air dry. Do not dry the parts
by placing them near a heater or in direct sunlight.
The rubber will deteriorate.
g. Operate the exhalation valve by hand to be sure it
works properly.
Note: Do not force-dry the parts by placing them in a
heater or in direct sunlight. The rubber will deteriorate.
When the facepiece is thoroughly dry, store the facepiece
in the plastic bag that it was shipped in.
3. In general, only the facepiece requires cleaning and
disinfecting after each use.
4. Re-attach NightFighter Heads-Up Display System
Receiver and Voicemitter Assembly.
a. Slide receiver onto facepiece bracket.
b. Finger-tighten thumb screw.
5. Thoroughly dry the facepiece and regulator after
cleaning and disinfecting. The facepiece can trap
water, which could enter the regulator.
REMOVING THE SPEED-ON ® HEAD HARNESS

4. Fold the end-tab sides together, then slide each tab
through its buckle.
