NOTE: Airflow ratings estimates are based on factory and independent testing @ 120 VAC with an air
straightener and a traverse of readings taken with a computing vane-anemometer. Actual results may vary
for various reasons, including motor, blower and HEPA filter tolerances. Factors such as filter loading,
reduced voltage to the motor, and inlet and outlet ducting will reduce airflow. Use these ratings as a
general guideline only as results can vary with each installation.

Unit won’t start when it is 
turned “ON.”

Filter loading indicators flashing.
