DANGER
Refrigerant gas is heavier air and replaces 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.
Do not ground units to water pipes, telephone wires,
•
or lightning rods because lightning strikes can cause
a severe shock hazard resulting in severe injury or
death.
Do not ground units to gas pipes because a gas leak
•
could result in an explosion which could lead to se-
vere injury or death.
If the refrigerant gas leaks during installation, venti-
•
late the area immediately.
Refrigerant gas may produce toxic gas if it comes in con-
tact with fire such as from a fan, heater, stove or cooking
device. Exposure to this gas could cause severe injury or
death.
Do not install the unit in an area where flammable ma-
•
terials are present due to the risk of explosion result-
ing in serious injury or death.
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 can cause se-
vere injury or death.
Installation of Outdoor Units
After completing the installation work, check that the
refrigerant gas does not leak.
•
Children playing with plastic bags face the danger of
•
death by suffocation.
Tear apart and throw away plastic packaging bags so that
children cannot play with them.
Safely dispose of the packing materials.
•
Packing materials, such as nails and other metal or
wooden parts, may cause stabs or other injuries.
WARNING
Ask your dealer or qualified personnel to carry out in-
•
stallation 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 in-
•
stallation 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 leak-
age, electric shocks, fire or the unit falling.
Install the unit on a foundation strong enough to with-
•
stand 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 pro-
•
vided for this unit and that all electrical work is car-
ried out by qualified personnel according to local
laws and regulations and this installation manual.
An insufficient power supply capacity or improper electri-
cal 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 ter-
minal 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.
•
Securely install the outdoor unit terminal panel.
•
If the terminal panel is not installed properly, dust or water
may enter the outdoor unit and fire or electric shock may
result.
When installing or relocating the system, be sure to
•
keep the refrigerant circuit free from substances oth-
er than the specified refrigerant (R-410A), such as air.
