non-abrasive dish soap. If you use a cleaning product, always wipe
the product off properly to avoid the discoloration of the unit. Do not
use abrasive or chemical cleaners because they may damage the
nishing. If the unit is used in a very dusty location, use a vacuum
brush to remove dust and other foreign objects from the grilles. Note
that cigarette smoke could yellow the unit and especially the discharge
