IMPORTANT SAFETY INSTRUCTIONS

All wiring must comply with local and national electrical codes and be installed by a qualified electrician. Never insert your fingers or any foreign objects into the air outlet. Take special care to warn children of these dangers. Be sure the air conditioner is properly grounded. To minimize shock and fire hazards, proper grounding is important. The power cord is equipped with a threeprong grounding plug for protection against shock hazards. Your air conditioner must be used in a properly grounded wall receptacle. If the wall receptacle you intend to use is not adequately 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 with outside protective cover in place. This could result in mechanical damage within the air conditioner.

The capacity of the room air conditioner must fit the room size for efficient and satisfactory operation. Install the room air conditioner on the shady side of your room. Do not block air flow inside with blinds, curtains or furniture; or outside with shrubs, enclosures, or other buildings. Keep blinds and drapes in other windows closed during the sunniest part of the day. Clean the air filter as recommended in the section Care and Cleaning .

Do not use an extension cord or an adapter plug.
