CAUTION concerning the Power Cord
Most appliances recommend they be placed upon
a dedicated circuit;
That is, a single outlet circuit which powers only

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 re. 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.
