electrician or service person if you aren’t sure if the outlet is
properly grounded. DO NOT MODIFY THE PLUG. If it will not fit the
outlet, have a proper outlet installed by a qualified electrician.
This appliance is designed for use on a nominal 120-volt circuit,

to an outlet having the same configuration as the plug. No plug
adapter should be used with this appliance.

a grounding plug. It must only be plugged into an outlet that is
properly installed and grounded in accordance with all local codes
and ordinances.
