Two or more people are needed to move and install the air conditioner. To prevent injury or strain, use proper lifting and carrying techniques when moving air conditioner. Carefully inspect location where air conditioner will be installed. Be sure it will support the weight of the air conditioner over an extended period of time. Handle air conditioner with care. Wear protective gloves whenever lifting or carrying the air conditioner. AVOID the sharp metal fins on the air conditioner evaporator and condenser coils.

4 Electrical Requirements Grounding Instructions WARNING To avoid risk of personal injury or death due to electrical shock: Electrical grounding is required on all air conditioners. Check with a qualified electrician if you are not sure intended electrical outlet is properly grounded. DO NOT ground to gas line. DO NOT use cold water pipe for ground if pipe is interrupted by plastic, non-metallic gaskets, or other insulating (non-conducting) materials. DO NOT modify plug on power cord. If plug does not fit electrical outlet, have a matching outlet installed by a qualified electrician. DO NOT have a fuse in the neutral or ground circuit. A fuse in the neutral or ground circuit could result in an electrical shock. DO NOT use an extension cord with this device. DO NOT use an adapter plug with this device. Observe all local codes and ordinances. For safety, air conditioner must be grounded. All air conditioners have a power supply cord with a threeprong grounding plug. To minimize possible electrical shock hazard, the power cord must only be plugged into a matching grounding wall receptacle in accordance with the National Electrical Code and any applicable local codes and ordinances. If an appropriate grounding-type wall receptacle is not available, have a properly grounded wall receptacle installed by a qualified electrician. If codes permit, and a separate grounding wire is used, have a qualified electrician determine if grounding path is adequate and uninterrupted by plastic, non-metallic gaskets, or other insulating (non-conductive) materials. Electrical Connection Devices covered in this manual require a 60 Hz supply. Refer to name plate on air conditioner for exact voltage requirements. Voltage requirements can also be determined by the type of plug on air conditioner. See following table (Table ). Table.
