04031.1 SAFETY PRECAUTIONSWARNINGThis symbol indicates the possibility of personnel injury or loss of life.CAUTIONThis symbol indicates the possibility of property damage or serious consequences.Installing, starting up, and servicing air-conditioning equipment can be hazardous due to system ressures,electrical components, and equipment location (roofs, elevated structures, etc.).Only trained, qualified installers and service mechanics should install, start-up, and serve this equipment.When working on the equipment, observe precautions in the literature and on tags, stickers, and labels attachedto the equipment.Follow all safety codes. Wear safety glasses and work gloves. Keep quenching cloth and fire extinguishernearby when brazing. Use care in handing, rigging, and setting bulky equipment.Read these instructions thoroughly and follow all warnings or cautions included in literature and attached to theunit. Consult local building codes and National Electrical Code for special requirement.To avoid personal injury, be careful when handling parts with sharp edges.Do not install the indoor or outdoor units in a location with special environmental conditions.Do not install in a place that can amplify the noise level of the unit or where noise and discharged airmight disturb neighbors.Perform the drainage/piping work securely according to the installation manual.Improper drain piping may result in water leakage and property damage.Do not instal the air conditioner in the following places.-The place where there is mineral oil or arsenic acid.-The place where corrosive gas (such as sulfurous acid gas) or combustible gas (such as thinner) canaccumulate or collect, or where volatile combustible substances are handled.-The place there is equipment that generates electromagnetic fields or high frequencey harmonics.The appliance shall be stored so as to prevent mechanical damage from occuring.Any person who is involve with working on or breaking into a refrigerant circuit should hold a currentvalid certificate from an industry-accredited assessment authority, which authorizes their competence tohandle refrigerants safely in accordance with an industry recognized assessment specification.Refrigerant gas is heavier than air and replaces oxygen. A massive leak could lead to oxygen depletion,especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.When the air conditioner is installed in a small room, provide appropriate measures to ensure thatthe concentration of refrigerant leakage occur in the room does not exceed the critical level.If the refrigerant gas leaks during installation, ventilate the area immediately.Refrigerant gas may produce a toxic gas if it comes in contact with fire such as from a fan heater, stove orcooking device. Exposure to this gas could cause severe injury or death.Disconnect from power source before attempting any electrical work. Connect the connective cablecorrectly.Wrongly connecting may result in electric parts damaged.Use the specified cables for electrical connections and attach the wires firmly to the terminal blockconnecting sections so that the external force is not exerted to the terminal.Be sure to provide grounding.Do not ground units to gas pipes, water pipes, lightning rods or telephone wires. Incomplete grounding couldcause a severe shock hazard resulting in injury or death.Safely dispose of the packing materials.Packing materials, such as nails and other matal or wooden parts, may cause stabs or other injuries. Tear apartand throw away plastic pacaging bags so that children will not play with them. Children playing with plastic bagsface the danger of suffocation.Do not install unit near concentrations of combustible gas or gas vapors.Be sure to use the supplied or exact specified installation parts.Use of other parts may cause the unit to come to lose, water leakage, electrical shock, fire or equipmentdamage.When installing or relocating the system, do not allow air or any substances other than thespecified refrigerant (R32) to enter the refrigeration cycle.Never modify this unit by removing any of the safety guards or bypassing any of the safetyinterlock switches.Electrical work should be carried out in accordance with the installation manual and the national,state and local electrical wiring codes.1. PREPARING FOR INSTALLATION 1. PREPARING FOR INSTALLATIONWARNINGBe sure to use a delicated power circuit. Never share the same power outlet with other appliance.In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this appliance must notbe supplied through an external switching device, such as a timer, or connected to a circuit that isregularly switched on and off by the utility.Use the prescribed cables for electrical connection with insulation protected by insulation sleevinghaving an appropriate temperature rating.Unconformable cables can cause electric leak, anomalous heat prodcution or fire.Do not use means to accelerate the defrosting process or to clean, other than those recommended bythe manufacturer.Below clause are required for the units adopt R32/R290 Refrigerant.The appliance shall be stored in a room without continuously operating ignition sources (for example:open flames, and operating gas appliance or an operating electric heater)Do not pierce or burn.Be aware that refrigerants may not contain an odour.Appliance shall be stored in a well-ventilated area where the room size corresponds to the room area asspecified for operation.For R32 refrigerant models:Appliance shall be installed, operated and stored in a room with a floor area larger than 4m2 .Appliance shall not be installed in an unvertilated space, if that space is smaller than 4m 2.For R290 refrigerant models, the minimum room size needed:<=9000Btu/h units: 13m2>9000Bth/h and <=12000Btu/h units: 17m2>12000Btu/h and <=18000Btu/h units: 26m 2>18000Btu/h and <=24000Btu/h units: 35m 2GB
