COMPONENT ASSEMBLY
Follow the steps below to assemble
your respirator. Do not don the respi-
rator until you have completed all
steps in this section.
1. Install the breathing tube:
Note: The breathing tube may be
worn either outside or under the
hood. Follow the instructions that
apply to assemble the breathing tube.
a. If the breathing tube is worn
outside the hood, locate the
3/4” hole in the front of the
hood. Push the male threaded
end of the breathing tube
through the hole until the hood
seals around the tube at the
first to sixth corrugation in the
breathing tube.
b. If the breathing tube is worn
under the hood, locate the 3/4”
metal plug in the collar inside
the hood and remove it by
stretching the rubber grommet.
c. Install the plug in the 3/4” hole
in the front of the hood by
stretching the rubber material.
d. Push the threaded end of the
breathing tube through the hole
in the collar until the rubber
grommet seals around the
breathing tube at the third cor-
rugation.
e. When using the parka hood,
P/N 807592, push the threaded
end of the breathing tube
through the elastic collar locat-
ed on the waist area of the
hood.
2. Assemble the facepiece to the
hood and breathing tube:
a. Unfasten the Velcro closure on
the collar and insert the face-
piece into the hood. (Parka
hood, P/N 807592, does not
have a collar).
b. Align the lens housing assem-
bly with the large opening in
the hood.
c. Stretch the rubber front of the
hood over the lens housing so
that the rubber forms a seal in
the channel between the door
frame and the lens housing
assembly.
d. Refasten the Velcro closure.
