RESPIRATOR ASSEMBLY
ASSEMBLING THE MASK-
MOUNTED RESPIRATOR
1. If necessary,
remove the cou-
pling nut from the
facepiece inhala-
tion housing. The
coupling nut may
be used if the
facepiece is used on MSA respira-
tors. Check that the inhalation
check valve and spider gasket are
in the facepiece inhalation housing.
The gasket is needed so that the
facepiece and motor-blower will
seal. The Ultravue Facepiece is
shown above.
2. Thread the
motor-blower
coupling nut into
the facepiece
until resistance is
encountered.
Continue tighten-
ing the coupling nut an additional
60 degrees (the distance of two
notches on the coupling nut) into
the facepiece.
3. If attached, unthread the filter from
the motor-blower assembly.
4. Check that there
is a gasket in the
motor-blower
housing. The
gasket is neces-
sary so that the
filter and motor-
blower will seal.
Do not use the respirator if the spi-
der gasket in the facepiece inhala-
tion housing or the gasket in the
motor-blower housing is missing or
appears damaged. Failure to follow
this warning will permit the contam-
inant to be drawn into the respirator
and inhaled, resulting in serious res-
piratory injury or death.
5. Thread the filter
into the motor
blower and
hand-tighten.
6. Line up the key
on the battery
cable plug with
the slot in the
female connector
on motor-blower.
7. Push the plug into female connec-
tor and turn to secure.
