Positive Pressure Seal Check: Cover the exhalation valve vents, and exhale gently to create a slight positive pressure. If air leakage is detected, re-adjust the position of the facepiece and the tension of both headstraps, and repeat the seal check until leakage is eliminated. |
Negative Pressure Seal Check: Cover both cartridges, and gently inhale and hold your breath. The facepiece should slightly collapse. If air leakage is detected, re-adjust the position of the facepiece, and the tension of both headstraps, and repeat the seal check until leakage is eliminated. |
