TO CLEAN GRILLE: Use a mild detergent, such as dishwashing liquid, and a soft cloth. DO NOT use abrasive cloths, steel
wool pads or scouring powders.
TO CLEAN FAN ASSEMBLY: Unplug motor cord from receptacle. To remove motor plate, find the single tab on the motor
plate (located next to the receptacle). Push up rear motor plate tab while pushing out on the side of the housing or insert a
screwdriver into the slot in the housing (next to tab) and twist screwdriver. Gently vacuum fan, motor and interior of housing.

The motor is permanently lubricated and never needs oiling. If the motor bearings are making excessive or unusual
noises, replace the motor with the exact service motor. You should replace the impeller at the same time.
