1. SAFETY CONSIDERATIONS
Please read these “SAFETY CONSIDERATIONS” carefully
before installing air conditioning equipment and be sure to
install it correctly. After completing the installation, make sure
that the unit operates properly during the start-up operation.
Please instruct the customer on how to operate the unit and
keep it maintained.
Also, inform customers that they should store this installation
manual along with the operation manual for future reference.

Safety Precaution
This unit is a class A product. In a domestic environment this
product may cause radio interference in which case the user
may be required to take adequate measures.
Meaning of warning and caution symbols.
WARNING ............. Failure to observe a warning may
result in death.
CAUTION .............. Failure to observe a caution may
result in injury or damage to the equip-
ment.
WARNING
• Ask your dealer or qualified personnel to carry out installation
work. Do not try to install the machine 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.
• When installing the unit in a small room, take measures
against to keep refrigerant concentration from exceeding
allowable safety limits in the event of refrigerant leakage. Con-
tact the place of purchase for more information. Excessive
refrigerant in a closed ambient can lead to oxygen deficiency.
• 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 taking into
account 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 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 and
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.
• If the refrigerant gas leaks during installation, ventilate the
area immediately.
Toxic gas may be produced if the refrigerant gas comes into
contact with fire.
• After completing the installation work, check that the refriger-
ant gas does not leak.
Toxic gas may be produced if the refrigerant gas leaks into
the room and comes into contact with a source of fire, such
as a fan heater, stove or cooker.
• Before touching electrical parts, turn off the unit.
CAUTION
• Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, light-
ning rod or a telephone ground wire.
Incomplete grounding may result in electric shocks.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in elec-
tric shocks.
• While following the instructions in this installation manual,
install drain piping in order to ensure proper drainage and
insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and prop-
erty damage.
• Install the indoor and outdoor units, power supply wiring and
connecting wires at least 1 meter away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient enough to eliminate the noise.)
• Remote controller (wireless kit) transmitting distance can
result shorter than expected in rooms with electronic fluores-
cent lamps. (inverter or rapid start types)
Install the indoor unit as far away from fluorescent lamps as
possible.
• Do not install the air conditioner in the following locations:
(a) where a mineral oil mist or an oil spray or vapor is pro-
duced, for example in a kitchen
Plastic parts may deteriorate and fall off or result in
water leakage.
(b) where corrosive gas, such as sulfurous acid gas, is pro-
duced
Corroding copper pipes or soldered parts may result in
refrigerant leakage.
(c) near machinery emitting electromagnetic waves
Electromagnetic waves may disturb the operation of the
control system and result in a malfunction of the equip-
ment.
(d) where flammable gases may leak, where there are car-
bon fiber or ignitable dust suspensions in the air, or
where volatile flammables such as thinner or gasoline
are handled.
Operating the unit in such conditions may result in fire.
