Figure 3. Leak Check
NOTE
Do not hold your breath longer than two or three
seconds, and do not pull a very strong vacuum.
The purpose is to see if the facepiece will seal
against a small amount of air pressure.
e. If a good fi t was achieved, proceed to step 4. If you
felt a leak, select a different size facepiece and repeat
steps a. through d. above.
f. If you cannot get a fi t with any size, then install a
Temple Insert Kit, P/N 962150 (small), P/N 962153
(medium), or P/N 962154 (large) into the facepiece
that fi t the best, and repeat steps a. through e. above.
If you still felt a leak when the facepiece was col-
lapsed toward your face, install a different size Tem-
ple Insert Kit, and repeat steps a. through e. above. If
you still cannot get a fi t with any of the temple inserts
installed, you cannot proceed.
