For personal safety, this appliance must be properly grounded.
This appliance is equipped with a three-prong groundling plug for your protection against shock hazard and should be plugged directly into a properly grounded receptacle.
Do not cut or remove the groundling prong from this plug.
The customer should have the wall receptacle and circuit checked by a qualified electrician to make sure the receptacle is properly grounded.
The power cord of this appliance is equipped with a 3-prong (grounding) plug which mates with a standard 3-prong grounding wall receptacle to minimize the possibility of electric shock hazard from this appliance.
Where a standard two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to have it replaced with a properly grounded three-prong wall receptacle.
Ensure proper ground a exists before use.

Do not use an adapter plug. Disconnecting of the power cord places undue strain on the adapter and leads to eventual failure of the adapter ground terminal.
