GENERAL NOTES ABOUT FAN SPEEDS

1. There are 5 fan speed settings that are incremented by momentarily pressing the speed button. Fan speed is displayed temporarily.
2. Adjusting the fan speed, like all air-moving equipment, involves a trade-off between noise and performance.
   a)A speed that is too low will be quieter, but may not deliver adequate airflow.
   b)A speed that is too high will be louder and may ‘over condition the space by drawing too much air from the branch duct.

Dust may be removed from the exterior surfaces using a soft cloth, the round brush attachment of your vacuum cleaner, or a cloth that has been lightly moistened with water and a mild, non-abrasive detergent.
