DONNING
FINAL HOOK-UP
1. Turn the power switch
on. Let air flow through
the motor-blower for a
f
ew seconds.
2. Check for an o-ring on
the end of the breath-
ing tube coupling nut.
The o-ring must be present to ensure a proper air-tight
seal. Failure to follow this warning can cause inhala-
tion of the contaminant resulting in serious respiratory
i
njury or death.
3. Thread the breathing tube onto the motor-blower and
hand-tighten the coupling nut.
Note: If you are wearing a half-mask facepiece and feel
air blowing out of the facepiece and into your eyes, the
facepiece is not fitted properly. All air should escape
through the exhalation valve. Don the facepiece again.
