GROUNDING INSTRUCTIONS

This appliance must be grounded. If it should malfunction
or breakdown, 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
grounding conductor and grounding plug. The plug must be
inserted into an appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordinances.

Improper connection of the equpment-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.

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 grounding attachment plug that looks like

the plug in the sketch.

Make sure that the appliance is connected to an outlet having the same configuration as the plug.

No adapter should

be

used with this appliance.
