NOTE
Never use abrasive cleaners or chemicals on hood
surfaces. Never use chlorine based cleaners or iron
wool pads to clean the hood. They may scratch or
mar the material, allowing pitting and rust to form.
Always rub with the grain of the stainless when
cleaning.
Replace hood lights, sensors, and other components as
necessary.
On front recirculation models, replace charcoal filter
routinely (as needed) to help catch cooking odor
molecules when recirculating air back into the space.
