CAUTION concerning the Power Cord

Most appliances recommend they be placed upon 
a dedicated circuit; 
That is, a single outlet circuit which powers only 
that appliance and has no additional outlets or 
branch circuits. Check the specification page of this 
owner’s manual to be certain. Do not overload wall 
outlets. Overloaded wall outlets, loose or damaged 
wall outlets, extension cords, frayed power cords, or 
damaged or cracked wire insulation are dangerous. 
Any of these conditions could result in electric 
shock or fire. Periodically examine the cord of your 
appliance, and if its appearance indicates damage 
or deterioration, unplug it, discontinue use of the 
appliance, and have the cord replaced with an 
exact replacement part by an authorized service 
center. Protect the power cord from physical or 
mechanical abuse, such as being twisted, kinked, 
pinched, closed in a door, or walked upon. Pay 
particular attention to plugs, wall outlets, and 
the point where the cord exits the appliance. To 
disconnect power from the mains, pull out the 
mains cord plug. When installing the product, 
ensure that the plug is easily accessible.
