grounded or protected by a time delay fuse or circuit breaker,
have a qualified electrician install the proper receptacle.
Ensure the receptacle is accessible after the unit installation.
Do not run air conditioner without side protective cover in place.
This could result in mechanical damage within the air conditioner.
Do not use an extension cord or an adapter plug.
