Installation

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 equipment-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. No adaptor 
should be used with this appliance.

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 V circuit,  

and has a grounded plug 

(figure 9). Make sure that 

the appliance is connected to an outlet having the 
same configuration as the plug. No adaptor should 
be used with this appliance.

This appliance is for use on a circuit having a nominal 
rating more than 120  V and is factory-equipped with  
a specific cord and plug to permit connection to a 
proper electric circuit. Make sure that the appliance is 
 connected to an outlet having the same configuration as 
the plug. No adaptor should be used with this  

appliance. 

If the appliance must be reconnected for use on a 
 different type of electric circuit, the reconnections should 
be made by a qualified service personnel.
