CAUTION FOR REFRIGERANT LEAKS ............................... 151. SAFETY CONSIDERATIONSRead these “SAFETY CONSIDERATIONS for Installation” carefullybefore installing air conditioning equipment. After completing the instal-lation, make sure that the unit operates properly during the startup oper-ation.Instruct the customer on how to operate and maintain the unit. Informcustomers that they should store this Installation Manual with the Oper-ation Manual for future reference.Always use a licensed installer or contractor to install this product.Improper installation can result in water or refrigerant leakage, electricalshock, fire, or explosion.Meanings of DANGER, WARNING, CAUTION, and NOTE Symbols:DANGER .................. Indicates an imminently hazardous situa-tion which, if not avoided, will result indeath or serious injury.WARNING................. Indicates a potentially hazardous situationwhich, if not avoided, could result in deathor serious injury.CAUTION.................. Indicates a potentially hazardous situationwhich, if not avoided, may result in minor ormoderate injury.It may also be used to alert against unsafepractices.NOTE ........................ Indicates situations that may result inequipment or property-damage accidentsonly.DANGER• Refrigerant gas is heavier than air and replaces oxygen. A mas-sive leak can lead to oxygen depletion, especially in base-ments, and an asphyxiation hazard could occur leading toserious injury or death.• Do not ground units to water pipes, gas pipes, telephone wires,or lightning rods as incomplete grounding can cause a severeshock hazard resulting in severe injury or death. Additionally,grounding to gas pipes could cause a gas leak and potentialexplosion causing severe injury or death.• If refrigerant gas leaks during installation, ventilate the areaimmediately. Refrigerant gas may produce toxic gas if it comesin contact with fire. Exposure to this gas could cause severeinjury or death.• After completing the installation work, check that the refriger-ant gas does not leak throughout the system.• Do not install unit in an area where flammable materials arepresent due to risk of explosions that can cause serious injuryor death.• Safely dispose all packing and transportation materials inaccordance with federal/state/local laws or ordinances. Packingmaterials such as nails and other metal or wood parts, includ-ing plastic packing materials used for transportation may causeinjuries or death by suffocation.WARNING• Only qualified personnel must carry out the installation work.Installation must be done in accordance with this installationmanual. Improper installation may result in water leakage, elec-tric shock, or fire.• When installing the unit in a small room, take measures to keepthe refrigerant concentration from exceeding allowable safetylimits. Excessive refrigerant leaks, in the event of an accident ina closed ambient space, can lead to oxygen deficiency.• Use only specified accessories and parts for installation work.Failure to use specified parts may result in water leakage, elec-tric shocks, fire, or the unit falling.• Install the air conditioner on a foundation strong enough that itcan withstand the weight of the unit. A foundation of insuffi-cient strength may result in the unit falling and causing injuries.• Take into account strong winds, typhoons, or earthquakeswhen installing. Improper installation may result in the unit fall-ing and causing accidents.• Make sure that a separate power supply circuit is provided forthis unit and that all electrical work is carried out by qualifiedpersonnel according to local, state, and national regulations.An insufficient power supply capacity or improper electricalconstruction may lead to electric shocks or fire.• Make sure that all wiring is secured, that specified wires areused, and that no external forces act on the terminal connec-tions or wires. Improper connections or installation may resultin fire.• When wiring, position the wires so that the control box covercan be securely fastened. Improper positioning of the controlbox cover may result in electric shocks, fire, or the terminalsoverheating.• Before touching electrical parts, turn off the unit.• Be sure to install a ground fault circuit interrupter if one is notalready available. This helps prevent electrical shocks or fire.• Securely fasten the outdoor unit terminal cover (panel). If theterminal cover/panel is not installed properly, dust or water mayenter the outdoor unit causing fire or electric shock.• When installing or relocating the system, keep the refrigerantcircuit free from substances other than the specified refrigerant(R410A) such as air. Any presence of air or other foreign sub-stance in the refrigerant circuit can cause an abnormal pres-sure rise or rupture, resulting in injury.• Do not change the setting of the protection devices. If the pres-sure switch, thermal switch, or other protection device isshorted and operated forcibly, or parts other than those speci-fied by Daikin are used, fire or explosion may occur.CAUTION• Do not touch the switch with wet fingers. Touching a switchwith wet fingers can cause electric shock.• Do not allow children to play on or around the unit to preventinjury.• Do not touch the refrigerant pipes during and immediately afteroperation as the refrigerant pipes may be hot or cold, depend-ing on the condition of the refrigerant flowing through therefrigerant piping, compressor, and other refrigerant cycleparts. Your hands may suffer burns or frostbite if you touch therefrigerant pipes. To avoid injury, give the pipes time to returnto normal temperature or, if you must touch them, be sure towear proper gloves.
