DANGER
• Do not ground units to water pipes, telephone wires or
lightning rods because 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 resulting in serious
injury or death.
• Refrigerant gas is heavier than air and displaces oxygen.
A massive leak could lead to oxygen depletion, espe-
cially 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 qualified personnel to carry out
installation work. Do not try to install the air conditioner
by yourself.
Improper installation may result in water leakage, electric
shocks or fire.
• Perform installation work in accordance with this instal-
lation 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 equip-
ment falling and causing injuries.
• Carry out the specified installation work after consider-
ing 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 pro-
vided for this unit and that all electrical work is carried
out by qualified personnel according to local laws and
regulations and this installation 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 con-
nections or wires.
Improper connections or installation may result in fire.
• When wiring the power supply and connecting the remote
controller wire and transmission wire, position the wires
so that the control box lid can be securely fastened.
Improper positioning of the control box lid may result in elec-
tric shocks, fire or the terminals overheating.
