Selection of installation location
• If you install the unit in a small room, take appropriate measures
to prevent the refrigerant from exceeding the limit concentration
even if it leaks. Consult the dealer from whom you purchased the
air conditioner when you implement the measures. Accumulation
of highly concentrated refrigerant may cause an oxygen
defi ciency accident.
• Do not install in a location where fl ammable gas may leaks are
possible. If the gas should leak and accumulate around the unit,
it may ignite and cause a fi re.
• When transporting the air conditioner, wear shoes with protective
toe caps, protective gloves and other protective clothing.
• When transporting the air conditioner, do not take hold of the
bands around the packing carton. You may injure yourself if the
bands break.
• Other than fl oor standing and console types, install the indoor
unit at least 2.5 m above the fl oor level since otherwise the users
may injure themselves or receive electric shocks if they poke
their fi ngers or other objects into the indoor unit while the air
conditioner is running.
• Do not place any combustion appliance in a place where it is
directly exposed to the wind of air conditioner, otherwise it may
cause imperfect combustion.
• Do not install in location where operation sound of the outdoor
unit may cause a disturbance. (Especially at the boundary line
with a neighbor, install the air conditioner while considering the
noise)

Installation
• Follow the instructions in the Installation Manual to install the air
conditioner. Failure to follow these instructions may cause the
product to fall down or topple over or give rise to noise, vibration,
water leakage or other failure.
• The designated bolts (M12) and nuts (M12) for securing the
outdoor unit must be used when installing the unit.
• Install the outdoor unit property in a location that is durable
enough to support the weight of the outdoor unit. Insuffi cient
durability may cause the outdoor unit to fall, which may result in
injury.
• Install the unit in the prescribed manner for protection against
strong wind and earthquake. Incorrect installation may result in
the unit falling down, or other accidents.
• Be sure to fi x the screws back which have been removed for
installation or other purposes.
Refrigerant piping
• Install the refrigerant pipe securely during the installation
work before operating the air conditioner. If the compressor
is operated with the valve open and without refrigerant pipe,
the compressor sucks air and the refrigeration cycles is over
pressurized, which may cause a injury.
• Tighten the fl are nut with a torque wrench in the specifi ed
manner. Excessive tighten of the fl are nut may cause a crack in
the fl are nut after a long period, which may result in refrigerant
leakage.
• Ventilate the air if the refrigerant gas leaks during installation.
If the leaked refrigerant gas comes into contact with fi re, toxic
gas may be produced.
