circuit  breaker  or  time  delay  fuse  does  not  exceed  the  amp  rating 
listed in Table 1.
DO NOT use an extension cord.
The cord provided will carry the proper amount of electrical power to

Proper grounding must be maintained at all times. Two prong receptacles 
must be replaced with a grounded receptacle by a certied electrician.

the air conditioner. Under no circumstances should you remove the 
ground prong from the plug.
