Grounding Instructions – This appliance must be grounded. If it
should malfunction or break down, grounding provides a path of least
resistance for electric current, to reduce the risk of electric shock. This
appliance is equipped with a cord having an equipment-grounding
conductor and grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
Danger –
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. Check with a qualified
electrician or service person if you are in doubt as to whether the outlet
is properly grounded. Do not modify the plug provided with the
appliance – if it will not fit the outlet, have a proper outlet installed by a
qualified electrician.
This appliance is for use on a nominal 120 volt circuit and has a
