branch circuits.
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 servicer. 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.
The MAINS plug is used as the disconnect device, and the disconnect device shall
remain readily operable.
