SAFETY PRECAUTIONS
Please read these "SAFETY PRECAUTIONS" carefully before
installing air conditioning equipment and be sure to install it
correctly.
Meaning of WARNING and CAUTION notices.
Both are important notices for safety. Be sure to follow them.
WARNING ............. Failure to follow these instructions
properly may result in personal injury
or loss of life.
CAUTION................Failure to observe these instructions
properly may result in property dam-
age or personal injury, which may be
serious depending on the circum-
stances.
After completing installation, conduct a test operation to con-
firm that the equipment operates without any problems. Then,
explain to the customer how to operate the equipment and take
care of it following the operation manual. Ask the customer to
store the installation manual along with the operation manual
for future reference.
This air conditioner comes under the term "appliances not
accessible to the general public".
WARNING
• Ask your dealer or qualified personnel to carry out installa-
tion work.
Do not attempt to install the air conditioner yourself. Improper
installation may result in water leakage, electric shocks or fire.
• Install the air conditioner in accordance with the instructions
in this installation manual.
Improper installation may result in water leakage, electric
shocks or fire.
• When installing the unit in a small room, take measures so
that the refrigerant may not exceed the limiting concentra-
tion in the event of refrigerant leakage.
Contact your dealer for further information. If the refrigerant
leaks and exceeds the limiting concentration, it may 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 the unit fall-
ing, water leakage, electric shocks or fire.
• Install the air conditioner on a foundation strong enough to
withstand the weight of the unit.
If a foundation does not have sufficient strength, the equip-
ment may fall and cause injury.

• Carry out the required installation work in consideration of
strong winds, typhoons or earthquakes.
If the installation work is not properly carried out, the unit
may fall down and cause accidents.
• The electrical work must be carried out by the qualified elec-
trician in accordance with the local laws and regulations and
this installation manual. Make sure to provide a dedicated
power supply circuit and never connect additional wiring to
the existing circuit.
An insufficient power supply capacity or improper electrical
work may lead to electric shocks or fire.
• Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or
telephone earth lead.
Imperfect earthing may result in electric shocks or fire.
A high surge current from lightning or other sources may
cause damage to the air conditioner.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in elec-
tric shocks or fire.
• Be sure to switch off the unit before touching any electrical
parts.
Touching a live part may result in electric shock.
• For wiring, use the specified wires and connect and fasten
them firmly so that no external force from the wires may be
applied to the terminal connections.
If the wires are not firmly connected and fastened, it may
cause heating, fire or the like.
• Wiring for power supply and between the indoor and outdoor
units must be properly laid and formed, and the control box
lid must be firmly fastened so that the wiring may not push
up the structural parts such as the lid.
If the lid is improperly fastened, it may cause electric shock
or fire.
• If refrigerant gas leaks during installation, ventilate the area
immediately.
Toxic gas may be produced if the refrigerant comes into con-
tact with fire.
• After completing installation, check for refrigerant gas leak-
age.
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.
• Do not directly touch refrigerant that has leaked from refrig-
erant pipes or other areas, as there is a danger of frostbite.
• Carry out drain piping properly following this installation
manual and insulate the pipe to prevent condensation.
Improper drain piping may result in indoor water leakage and
property damage.
• Install the indoor and outdoor units, power supply and
transmission wirings at least 1 meter away from televisions or
radios to prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1
meter may not be sufficient to eliminate noise.)
• Install the indoor unit as far as possible from fluorescent
lamps.
If a wireless kit is installed in a room where the electronic
lighting type (inverter or rapid start types) fluorescent lamps
exist, the transmitting distance of a remote controller may be
shorter.
• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or
2. Where corrosive gas, such as sulphurous acid gas, is

Corrosion of copper pipes or brazed parts may occur and
cause refrigerant leakage.
