into an outlet that is properly installed and grounded.
DANGER - Improper use of the grounding plug can result in a risk of electric shock.
If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to
either flat blade terminal. The wire insulation having an outer surface that is green with or without
yellow stripes is the grounding wire.
Check with a qualified electrician or serviceman if the grounding wire instructions are not
completely understood, or if in doubt as to whether the product is properly grounded.
This product is factory equipped with a specific electric cord and plug to permit connection to a
proper electric circuit. Make sure that the product is connected to an outlet having the same
configuration as the plug. No adapter should be used with this product. Do not modify the plug
provided - if it will not fit in the outlet, have the proper outlet installed by a qualified electrician. If
the product must be reconnected for use on a different type of electric circuit, the reconnection
should be made by qualified service personnel.
If it is necessary to use an extension cord, use only a three wire extension cord that has a three
blade grounding plug, and a three-slot receptacle that will accept the plug on the product.
