CAUTION FOR REFRIGERANT LEAKS ........................ 17SAFETY CONSIDERATIONS1.Read these “SAFETY CONSIDERATIONS for Installation”carefully before installing air conditioning equipment. Aftercompleting the installation, make sure that the unit operatesproperly during the startup operation.Instruct the customer on how to operate and maintain the unit.Inform customers that they should store this Installation Manu-al with the Operation Manual for future reference.Always use a licensed installer or contractor to install thisproduct. Improper installation can result in water or refrigerantleakage, electrical shock, fi re, or explosion.Meanings of DANGER, WARNING, CAUTION, and NOTESymbols:DANGER ................ Indicates an imminently hazardoussituation which, if not avoided, willresult in death or serious injury.WARNING .............. Indicates a potentially hazardoussituation which, if not avoided, couldresult in death or serious injury.CAUTION ............... Indicates a potentially hazardoussituation which, if not avoided, mayresult in minor or moderate injury.It may also be used to alert againstunsafe practices.NOTE ..................... Indicates situations that may result inequipment or property-damageaccidents only.DANGERRefrigerant gas is heavier than air and replaces oxygen.•A massive leak can lead to oxygen depletion, especiallyin basements, and an asphyxiation hazard could occurleading to serious injury or death.Do not ground units to water pipes, gas pipes, tele-•phone wires, or lightning rods as incomplete groundingcan cause a severe shock hazard resulting in severeinjury or death. Additionally, grounding to gas pipescould cause a gas leak and potential explosion causingsevere injury or death.If refrigerant gas leaks during installation, ventilate the•area immediately. Refrigerant gas may produce toxicgas if it comes in contact with fire. Exposure to this gascould cause severe injury or death.After completing the installation work, check that the•refrigerant gas does not leak throughout the system.Do not install unit in an area where flammable materials•are present due to risk of explosions that can causeserious injury or death.Safely dispose all packing and transportation materials•in accordance with federal/state/local laws or ordinanc-es. Packing materials such as nails and other metal orwood parts, including plastic packing materials used fortransportation may cause injuries or death by suffoca-tion.WARNINGOnly qualified personnel must carry out the installation•work. Installation must be done in accordance with thisinstallation manual. Improper installation may result inwater leakage, electric shock, or fire.When installing the unit in a small room, take measures•to keep the refrigerant concentration from exceedingallowable safety limits. Excessive refrigerant leaks, inthe event of an accident in a closed ambient space, canlead to oxygen deficiency.Use only specified accessories and parts for installation•work. Failure to use specified parts may result in waterleakage, electric shocks, fire, or the unit falling.Install the air conditioner on a foundation strong•enough that it can withstand the weight of the unit. Afoundation of insufficient strength may result in the unitfalling and causing injuries.Take into account strong winds, typhoons, or earth-•quakes when installing. Improper installation may resultin the unit falling and causing accidents.Make sure that a separate power supply circuit is pro-•vided for this unit and that all electrical work is carriedout by qualified personnel according to local state, andnational regulations. An insufficient power supplycapacity or improper electrical construction may lead toelectric shocks or fire.Make sure that all wiring is secured, that specified wires•are used, and that no external forces act on the terminalconnections or wires. Improper connections or installa-tion may result in fire.
