Figure 22 – Fitting Seal Check Cap
Check that no air is flowing from the exhalation valve. Breathe normally. Using your fingers, feel around the perimeter
of the mask for leaks. You will feel any leak as a cool flow of air over your finger. For greater sensitivity breathe out
firmly to raise the mask pressure. Wetting your fingers will make it easier to feel tiny leaks. If necessary tighten the
mask. To tighten the mask, place one hand against the back of the blower and the other over the front of the mask.
Push the blower forwards and the mask back, tightening the fit. You will hear a series of clicks as the mask is
tightened. Be careful to tighten each side by the same amount. After each tightening, feel for leaks again. Tilt your
head down (look at the ground) and up (look at the sky). Check that there are still no leaks. Look right and left,
checking for leaks. Adjust if necessary. Once you can feel no leaks from the mask, the seal check is complete.
WARNING
IF A SATISFACTORY SEAL CHECK CANNOT BE ACHIEVED, DO NOT ENTER THE CONTAMINATED
ZONE.
Remove the Seal Check Cap by gently twisting the handle so that one side of the cap comes loose from the
exhalation valve. Be careful not to dislodge the Exhalation Valve Cover. See Figure 23
.
Figure 23 – Removing Seal Check Cap
WARNING
Be sure to remove the Seal Check Cap (Half Mask variants) before entering the contaminated area.
The Cap blocks the exhalation valve, making it more difficult for your exhaled air to be expelled
from the mask. Failure to remove the cap will lead to build-up of Carbon Dioxide in the mask and
may result in headache or dizziness.
Never leave the Cap in place for more than 2 minutes!
STEP 6 – INSTALL STERI-PLUS EXHALATION FILTER (OPTIONAL)
Remove the respirator and align the assembled case and filter to the PAF-1111 Standard Exhalation Valve Cover so
that the vents on the outer case are at the bottom of the mask. Push the assembled case onto the exhalation valve
until it clicks into place as shown in Figure 24.
