DANGER
Refrigerant gas in heavier air and replaces oxygen. A •
massive leak could lead to oxygen depletion, especially
in basements, and an asphyxiation hazard could occur
leading to serious injury or death.
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 fl ammable materials
•
are present due to risk of explosion resulting in 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 fi re such as from a fan, heater, stove or cooking device.
Exposure to this gas could cause 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 fi re such as from a fan, heater, stove or cooking device.
Exposure to this gas could cause 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 qualifi ed personnel to carry out •
installation work. Do not try to install the machine by
yourself.
Improper installation may result in water leakage, electric
shocks or fi re.
Perform installation work in accordance with this instal- •
lation manual.
Improper installation may result in water leakage, electric
shocks or fi re.
When installing the unit in a small room, take measures •
against to keep refrigerant concentration from exceed-
ing allowable safety limits in the event of refrigerant
leakage.
Contact the place of purchase for more information. Exces-
sive refrigerant in a closed ambient can lead to oxygen
defi ciency.
Be sure to use only the specifi ed accessories and parts •
for installation work.
Failure to use the specifi ed parts may result in water leak-
age, electric shocks, fi re or the unit falling.
Install the air conditioner on a foundation strong •
enough to withstand the weight of the unit.
A foundation of insuffi cient strength may result in the equip-
ment falling and causing injuries.
Carry out the specifi ed 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 pro- •
vided for this unit and that all electrical work is carried
out by qualifi ed personnel according to local laws,
regulations and this installation manual.
An insuffi cient power supply capacity or improper electrical
construction may lead to electric shocks or fi re.
Make sure that all wiring is secured, the specifi ed wires •
are used, and no external forces act on the terminal
connections or wires.
Improper connections or installation may result in fi re.
