TAL 114 (L) Rev. 4 - 10090982
USING THE RESPIRATOR
Return to a safe atmosphere and
discard the respirator immediately if
the facepiece becomes discolored,
crazed, blistered or cracked, or if
other signs of deterioration of the
facepiece, motor-blower, filter or
battery pack are observed.
You can breathe through the respi-
rator with the motor-blower off,
but breathing resistance may be
noticed, as with a negative-pres-
sure respirator.
DECONTAMINATION
The OptimAir Mask-Mounted PAPR
may be used in some applications
which may require decontamination of
personal and respiratory equipment
before the respirator may be removed.
One such application is asbestos-
exposure decontamination.
Turn the motor-blower off before
entering a decontamination shower.
The OptimAir Mask-Mounted PAPR
still provides respiratory protection
with the motor-blower off, because all
air is still drawn through the filter.
However, breathing resistance will be
greater than when the motor-blower is
supplying air to the facepiece.
REMOVING THE RESPIRATOR
1. Return to fresh air and clean the
outer surfaces of the respirator
before removing the facepiece.
2. Turn the power switch off.
3. Place your fingertips behind the
headstraps. Place your thumbs on
the buckles.
4. Pull the top of the buckles away
from your head. Repeat as needed
to loosen the headstraps.
5. Grip the facepiece by the inhala-
tion housing.
6. Pull the face-
piece out, then
up over your
head.
Do not pull the Ultravue Facepiece
by the exhalation valve assembly.
The facepiece rubber or the valve
assembly can be damaged.
7. Remove the retaining clip from
your shirt or belt.
8. Remove the support belt. Be care-
ful that you do not drop the battery
pack.
