GROUNDING INSTRUCTIONS

This appliance is equipped with a cord having a grounding wire with a grounding plug which must be plugged
into an outlet that is properly installed and grounded. In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an escape wire for the electric current.

WARNING—Improper use of the grounding can result in a risk of electric shock. Consult a qualified elec­trician or service agent if the grounding instructions are not completely understood, or if doubt exists as to
whether the appliance is properly grounded.
