To select one of the airflow settings by pressing the “+” button to
adjust to a higher speed or press the “-“ button to adjust to a lower
speed. The LED display will indicate the selected speed. Low, Me-

are active in the room. For best results, set the unit on a higher speed
setting during these times for high demand cleaning and circulation.
Set the unit to a lower setting for quieter operation when activity is
reduced.
Quick Clean Speed (PCO500 Only)

when airborne particle levels are high. Press the (+) on the fan speed
control until the Quick Clean icon (highlighted above) is displayed.
You will immediately notice a dramatic increase in airflow that will al-
