ELECTRICAL REQUIREMENTS & SAFETY PRECAUTIONS
Power Cord with
Arc Detection Device
The power cord supplied with this air conditioner is equipped with an Arc Detection Device designed to shut off power to the unit when it senses an arc fault condition. An arc fault is an unintentional electrical discharge that occurs when electrical products or wires are damaged, aged, or improperly used. An arc fault can be potentially hazardous if left undetected.
WARNING
•Do not remove or modify this plug
•Do not use as an on/off switch
•Do not use outdoors
•Do not push furniture against or place furniture on the electrical cord. This can trip the test switch and/or damage the cord and become a potential condition for arcing
•Do not attempt to repair the cord. If the cord requires replacement, call an authorized servicer.
•The Arc Detection Device is not a Ground Fault Interrupter and should not be used as such
•The Arc Detection Device contains an electronic circuit board and should not be submerged or exposed to water spray

Warning 
Electrical Shock Hazard
• Plug unit only into a grounded electrical outlet.
•Do not use an extension cord or plug adapter with this unit.
•Do not operate unit with decorative front or filter removed.
•Failure to follow these precautions could result in electrical shock, fire or personal injury.
•If the air conditioner has a serial plate rating of 115 volts and greater than 7.5 amps, it must have its own fuse or circuit breaker, and no other device or unit should be operated on that fuse or circuit breaker.
•If the air conditioner has a serial plate rating of 230 volts, it must have its own fuse or circuit breaker, and no other device or unit should be operated on that fuse or circuit breaker.
•We recommend that a qualified electrician install unit in accordance with the National Electrical Code and local codes and ordinances.
•Use copper conductors of correct wire gauge and protector size only.
•Do not alter cord or plug end. Do not remove warning label on cord.
Important Grounding Requirements
•Air conditioner has a three-prong grounding plug on the power supply cord, which must be plugged into a properly grounded three-prong wall receptacle for your protection against possible shock hazard. For models up to and including 7.5 amperes, use a grounding type wall receptacle to match the cord plug.
•For models above 7.5 amperes use a single outlet grounding type wall receptacle to match the cord plug.
Warning
Do not operate this air conditioner without proper time delay circuit protection (circuit breaker or fuse). Refer to serial plate for proper power supply requirements.

Additional Safety Precautions
•Do not cut, alter or remove any of the expanded polystyrene (styrofoam) inside this air conditioner.
•Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. The fumes can create a fire hazard or explosion.
•Do not introduce objects in the air discharge area. This could cause permanent damage.
•Do not pour liquids on the air conditioner as this could cause a malfunction. With the unit unplugged, use a damp cloth for cleaning the unit.
•Do not use strong solvents to clean the air conditioner.
•Clean the air conditioner filter every two weeks to avoid overheating caused by air obstruction. Do not operate without filter.
•Do not obstruct the air intake area of your air conditioner, as this could cause overheating, thus activating the unit’s security switch and shutting off the unit.
•Do not block air circulation to outside louvers of cabinet.
•Do not block air flow inside with blinds, curtains, or furniture, or outside with shrubs, enclosures, or other buildings.
•Do not run the air conditioner with an outside protective cover in place. This could result in fire or mechanical damage within the air conditioner.
•Depending on the model, your air conditioner may weigh as much as 95 pounds. To insure safe handling, obtain the necessary help to lift and position the unit during installation and removal.
•Handle air conditioner with care. Wear protective gloves whenever lifting or carrying the unit.
•Carefully inspect the location where the air conditioner will be installed. Be sure it will support the weight of the unit over an extended period of time.
