®

 Electric 

Corporation may result in a risk of fire, electric shock or injury to 

persons or damage to property.

1.4 

To reduce the risk of damage to the electric plug or cord, pull by the plug rather than the

specified in section 8.

any maintenance or cleaning. Simply turning off the controls will not reduce this risk.

1.7

immediately by a qualified service person. (Call customer service at 1-800-621-5485.)
