DANGER
• Do not ground the unit to water pipes, telephone wires or lightning rods as incomplete grounding
could cause a severe shock hazard resulting in severe injury or death, and to gas pipes because a
gas leak could result in an explosion which could lead to severe injury or death.
• Do not install unit in an area where flammable materials are present due to risk of explosion result-
ing in serious injury or death.
• Refrigerant gas is heavier than air and displaces oxygen. A massive leak could lead to oxygen depletion,
especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
• If the refrigerant gas leaks during installation, ventilate the area immediately.
Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan, heater, stove or
cooking device. Exposure to this gas could result in severe injury or death.
• After completing the installation work, check that the refrigerant gas does not leak.
Refrigerant gas may produce toxic gas if it comes in contact with fire such as from a fan, heater, stove or
cooking device. Exposure to this gas could result in severe injury or death.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries. Tear
apart and throw away plastic packaging bags so that children will not play with them. Children playing with
plastic bags face the danger of death by suffocation.
WARNING
• Ask your dealer or an authorized personnel to carry out installation work. Do not try to install the
unit by yourself.
Improper installation may result in water leakage, electric shocks or fire.
• Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electric shocks or fire.
• Be sure to use only the specified accessories and parts for installation work.
Failure to use the specified parts may result in water leakage, electric shocks, fire or the unit falling.
• Install the air conditioner on a foundation strong enough to withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment falling and causing injuries.
• Carry out the specified installation work after taking account of strong winds, typhoons or
earthquakes.
Improper installation work may result in the equipment falling and causing accidents.
• Make sure that a separate power supply circuit is provided for this unit and that all electrical work
is carried out by an authorized personnel according to local laws and regulations and this installa-
tion manual.
An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire.
• Make sure that all wiring is secured, the specified wires are used, and no external forces act on the
terminal connections or wires.
Improper connections or installation may result in fire.
• When wiring the power supply and connecting the remote controller wiring and transmission
wiring, position the wires so that the electric parts box lid can be securely fastened.
Improper positioning of the electric parts box lid may result in electric shocks, fire or the terminals
overheating.
• Before touching electrical parts, turn off the unit.
• Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric shock.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks, or fire.
• Do not install the air conditioner in the following locations:
(a) where a mineral oil mist or an oil spray or vapor is produced, for example in a kitchen. Plastic parts may
deteriorate and fall off or result in water leakage.
