This product should be operated only with the type of
power source indicated on the label.  If you are not sure
of the type of power supply to your home, consult your
product dealer or local power company.

This product is equipped with a three-wire plug.  This
plug will fit only into a grounded power outlet.  If you are
unable to insert the plug into the outlet, contact your
electrician to install the proper outlet.  Do not defeat the
safety purpose of the grounded plug.

Power-supply cords should be routed so that they are
not likely to be walked on or pinched by items placed
upon or against them.  Pay particular attention to cords
at doors, plugs, receptacles, and the point where they
