7. Install the white clamp over both the hood and breathing tube.  Squeeze the clamp until 
    the clamp teeth engage.  Be sure that the clamp is

snug so the breathing tube does not

Do not kink or crush the breathing tube.  This could restrict airflow and allow the user to be 
exposed to contaminants.
