Do not operate the button with wet hand. It may cause electric shock. When a burning appliance is used together with the unit, ventilate frequently. If ventilation is not sufficient, it may cause oxygen deficiency accident. Do not place a burning appliance where the airflow from the unit is directly blown. It may cause the imperfect combustion of the equipment. Make sure that the unit installation foundation is not damaged due to long-term use. If it is left to stand, the unit may fall down causing injury. Do not wash the unit with water, nor place a vase with water on the unit. It may cause electric shock or ignition. Do not install the unit where the airflow is directly blown to animals and plants. They may suffer from adverse effect. Before cleaning, make sure to stop operation and cut off the power. The fan inside rotates at high speeds. Make sure to use proper size of fuse. Using steel wire or copper wire may lead to failure or fire. Do not store a flammable spray etc. near the unit, nor blow directly to the unit. It may lead to fire. Before maintenance, make sure to stop operation and cut off the power. The fan inside rotates at high speeds. When the unit isn’t used for a long-term, cut off the power. The accumulation of dirt may lead to heat generation or fire. But, before resuming the operation, turn on the unit for six hours beforehand to save harmless. Do not place any other electric appliances or household goods below or around the air conditioner. Dripping from the unit may lead to failure or contamination. DANGER INSTALLATION PRECAUTIONS Make sure to perform grounding work. Do not connect grounding wire to any gas pipe, water pipe, conductor rods or telephones. Incomplete grounding may cause electric shock through leakage of electricity. Make sure to mount a leakage breaker. Otherwise electric shock may occur. Please consult your dealer or a specialist for the mounting. Do not mount where flammable gas leakage can happen. If leaked gas stagnates in the unit, the gas may cause fire. Make sure to layout the drain pipe so that the water is completely drained. Otherwise, water may leak and wet household goods. CAUTION ENGLISH Do not expose yourself directly to cooled air flow for a long time or cool too much. It may be cause of deconditioning or health disorder. Do not insert fingers or sticks into the air inlet or outlet grilles. It may cause injuries because of the fan rotating at high speed. DANGER OPERATION PRECAUTIONS The emission sound pressure level from each Indoor and Outdoor unit is under 70 dB(A). 2 Do not touch the aluminum fin. Otherwise it may lead to injuries. Do not clean the inside of the indoor unit by yourself. Make sure to consult your dealer or user inquiry counter specified by our company. If you select incorrect detergent or improper method, resin parts may be damaged and lead to water leakage. If the detergent is dropped on the electric component or motor, it may lead to failure, smoking or ignition. Do not place objects on the outdoor unit, nor mount on it. It may lead to injuries resulting from dropping or falling. During the operation or maintenance, do not use an unstable footrest. It may lead to injuries resulting from falling. During thunderstorm, stop the operation and turn off the switch. A lightning strike may lead to failure. After several seasons of operating, inspections and maintenances are required except routine care and cleaning. Accumulated dirt or dust inside the indoor unit may cause odor, water leakage through the clogging of water discharging pipe for dehumidification. Specialized information and skills are required for inspections and maintenances. Therefore contact your dealer. Do not place any object around the outdoor unit, nor allow fallen leaves to pile up. Fallen leaves may induce insects and worms in them, and they may lead to failure, ignition or smoking by touching electric components. Do not use with inlet/outlet grilles or other panel removed. Otherwise, it may lead to injuries. Do not operate or stop the unit by using the power supply switch. It may lead to fire or water leakage. If auto restart is set effectively, the fan may rotate suddenly causing injuries. Do not touch blowout port when the swing louver moves. Otherwise, it may lead to injuries. Do not strain the remote control cord. A part of core wire may be cut off causing electric leakage. Do not use water heater etc. near the indoor unit or remote control. If a Vapor-generating appliance is used near them, it may lead to water drop causing electric leakage or short circuit. Do not use the unit where powder or fiber is floating. Fine powder or fiber passing through the air filter may stagnate inside the unit and lead to electric leak or short circuit. Do not place objects under the unit which must avoid being exposed to water. Over 80 percent humidity or the clogging of drain pipe may damage them through dew dropping. Never perform any modification. Contact your dealer for repairing. Improper repairing may lead to water leakage, electric shock or fire. Normally the refrigerant does not leak. But if it leaks and contacts fire such as fan heater, space heater or cooking heater, it may produce toxic chemicals. When repairing refrigerant leakage, determine the service with the service staff that the repair has been finished without fault. If it is required to relocation and reinstall the unit, consult your dealer or a specialist. Improper installation of air conditioning unit may cause water leakage, electric shock and/or fire. Before repairing or checking indoor unit, be sure to turn off “Indoor unit power supply breaker”. It can result in electric shock or injury due to rotation of indoor unit fan if you perform check or repair with the “Indoor unit power supply breaker” turned on. Place the panels removed for repairing or checking on the stable spot. Otherwise, dropping or falling may lead to injury.

CAUTION Do not use for particular purpose such as the storage of food, animals and plants, precision apparatus and arts etc. Storage goods may degrade. Do not operate the button with wet hand. It may cause electric shock. When a burning appliance is used together with the unit, ventilate frequently. If ventilation is not sufficient, it may cause oxygen deficiency accident. Do not place a burning appliance where the airflow from the unit is directly blown. It may cause the imperfect combustion of the equipment. Make sure that the unit installation foundation is not damaged due to long-term use. If it is left to stand, the unit may fall down causing injury. Do not wash the unit with water, nor place a vase with water on the unit. It may cause electric shock or ignition. Do not install the unit where the airflow is directly blown to animals and plants. They may suffer from adverse effect. Before cleaning, make sure to stop operation and cut off the power. Otherwise the fan inside may unexpectedly start operation, leading to injury. Make sure to use proper size of fuse. Using steel wire or copper wire may lead to failure or fire. Do not store a flammable spray etc. near the unit, nor blow directly to the unit. It may lead to fire. Before maintenance, make sure to stop operation and cut off the power. It may cause injuries because of the fan rotating at high speed. Do not place any other electric appliances or household goods below or around the air conditioner. Dripping from the unit may lead to failure or contamination. DANGER INSTALLATION PRECAUTIONS Make sure to perform grounding work. Do not connect grounding wire to any gas pipe, water pipe, conductor rods or telephones. Incomplete grounding may cause electric shock through leakage of electricity. Make sure to mount a leakage breaker. Otherwise electric shock may occur. Please consult your dealer or a specialist for the mounting. Do not mount where flammable gas leakage can happen. If leaked gas stagnates around the unit, the gas may cause fire. Make sure to layout the drain pipe so that the water is completely drained. Otherwise, water may leak and wet household goods. CAUTION ENGLISH Do not expose yourself directly to cooled air for a long time or cool too much. It may be cause of deconditioning or health disorder. DANGER OPERATION PRECAUTIONS 2 Do not touch the aluminum fin. Otherwise it may lead to injuries. Do not clean the inside of the indoor unit by yourself. Make sure to consult your dealer or user inquiry counter specified by our company. If you select incorrect detergent or improper method, resin parts may be damaged and lead to water leakage. If the detergent is dropped on the electric component or motor, it may lead to failure, smoking or ignition. Do not place objects on the outdoor unit, nor mount on it. It may lead to injuries resulting from dropping or falling. During the operation or maintenance, do not use an unstable footrest. It may lead to injuries resulting from falling. During thunderstorm, stop the operation and turn off the switch. A lightning strike may lead to failure. After several seasons of operating, inspections and maintenances are required except routine care and cleaning. Accumulated dirt or dust inside the indoor unit may cause odor, water leakage through the clogging of water discharging pipe for dehumidification. Specialized information and skills are required for inspections and maintenances. Therefore contact your dealer. Do not place any object around the outdoor unit, nor allow fallen leaves to pile up. Fallen leaves may induce insects and worms in them, and they may lead to failure, ignition or smoking by touching electric components. Do not use with inlet/outlet grilles or other panel removed. Otherwise, it may lead to injuries. Do not operate or stop the unit by using the power supply switch. It may lead to fire or water leakage. If auto restart is set effectively, the fan may rotate suddenly causing injuries. Do not touch blowout port when the swing louver moves. Otherwise, it may lead to injuries. Do not strain the remote control cord. A part of core wire may be cut off causing electric leakage. Do not use water heater etc. near the indoor unit or remote control. If a Vapor-generating appliance is used near them, it may lead to water drop causing electric leakage or short circuit. Do not use the unit where powder or fiber is floating. Fine powder or fiber passing through the air filter may stagnate inside the unit and lead to electric leak or short circuit. Do not place objects under the unit and around it which must avoid being exposed to water. Over 80 percent humidity or the clogging of drain pipe may damage them through dew dropping. Never perform any modification. Contact your dealer for repairing. Improper repairing may lead to water leakage, electric shock or fire. Normally the refrigerant does not leak. But if it leaks and contacts fire such as fan heater, space heater or cooking heater, it may produce toxic chemicals. When repairing refrigerant leakage, determine the service with the service staff that the repair has been finished without fault. If it is required to relocation and reinstall the unit, consult your dealer or a specialist. Improper installation of air conditioning unit may cause water leakage, electric shock and/or fire. Before repairing or checking indoor unit, be sure to turn off “Indoor unit power supply breaker”. It can result in electric shock or injury due to rotation of indoor unit fan if you perform check or repair with the “Indoor unit power supply breaker” turned on. Place the panels removed for repairing or checking on the stable spot. Otherwise, dropping or falling may lead to injury.
