After completingthe installation, make sure that the unit operates properly duringthe startup operation.Instruct the user on how to operate and maintain the unit.Inform users that they should store this installation manual withthe operation manual for future reference.Always use a licensed installer or contractor to install this product.Improper installation can result in water or refrigerant leakage,electric shock, fire, 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 resultin equipment or property-damageaccidents only.DANGER• Refrigerant 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, telephonewires, or lightning rods as incomplete grounding can causea severe shock hazard resulting in severe injury or death.Additionally, grounding to gas pipes could cause a gas leakand potential explosion causing severe injury or death.• If refrigerant gas leaks during installation, ventilate thearea immediately. Refrigerant gas may produce toxic gasif it comes into contact with fire. Exposure to this gas couldcause severe injury or death.• After completing the installation work, check that therefrigerant gas does not leak throughout the system.• Do not install unit in an area where flammable materialsare present due to risk of explosions that can causeserious injury or death.• Safely dispose all packing and transportation materialsin accordance with federal/state/local laws or ordinances.Packing materials such as nails and other metal orwood parts, including plastic packing materials used fortransportation may cause injuries or death by suffocation.WARNING• Only qualified personnel must carry out the installationwork. 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 measuresto keep the refrigerant concentration from exceedingallowable safety limits. Excessive refrigerant leaks, in theevent of an accident in a closed ambient space, can leadto oxygen deficiency.• Use only specified accessories and parts for installationwork. Failure to use specified parts may result in waterleakage, electric shock, fire, or the unit falling.• Install the air conditioner or heat pump on a foundationstrong enough that it can withstand the weight of the unit.A foundation of insufficient strength may result in the unitfalling and causing injuries.• Take into account strong winds, typhoons, or earthquakeswhen installing. Improper installation may result in the unitfalling and causing accidents.
