If An Airflow Alert Activates
The most common causes of an Airflow Alert are:
Blockage of the inlet grilles or exhaust outlet.
Removal of the work surface or grille during operation.
Resetting the Airflow Alert System
The Airflow Alert automatically resets to normal operation once the motor
speed has stabilized.

Planning
Thoroughly understand procedures and equipment required before
beginning work.
Arrange for minimal disruptions, such as room traffic or entry into the
room while the cabinet is in use.
Start-up
Turn off UV light if included.
Slowly raise the sash until the bottom of the sash aligns with the sash
indicator decal located on the left side of the work area.
Turn on the fluorescent light and cabinet blower if the Smart-Start
features have not been activated.
Check the air grilles for obstructions.
