mend inspection of the product at least once every 12 months to 
ensure that the motor, impellor, and supporting guards are clean. All 
fastenings should be checked for tightness and security. In addition, 
all rotating items should be checked. To inspect the unit, disconnect it 
from the power supply and any duct work. If debris is evident on the 
impeller, clean it with a damp (not wet) cloth. DO NOT use any deter-
gents or abrasive materials for cleaning.
