Provide maximum comfort,
clean air and optimise energy saving
ECONAVI + INVERTER The Perfect Energy Saving Technology
ECONAVI detects where energy is normally wasted and adjusts cooling/heating power depending on
room conditions and activity levels. Then, INVERTER leverages ECONAVI sensor data and varies
compressor rotation speed. This helps to optimize cooling/heating operation and reduces wasteful
cooling/heating.
See “To learn more...” for details.
nanoe For a freshness and cleaner environment
nanoe generates negative ions using the air in the room to give a healthy air.
It also provides moisturizing effect on the skin or hair and reduces the smell in the room and constrains
propagations of mold and bacteria.

the seriousness of which is classified as below:
This appliance is filled with R32 (mild
flammable refrigerant). If the refrigerant
is leaked and exposed to an external
ignition source, there is a risk of fire.
WARNING This sign warns of
death or serious injury.
CAUTION This sign warns of
injury or damage to
property.
The instructions to be followed are classified by

than Amin (m²) and keep away from
ignition sources, such as heat/sparks/
open flame or hazardous areas such as
gas appliances, gas cooking, reticulated
gas supply systems or electric cooking
appliances, etc. (Refer to Table A of
Installation instructions table for Amin (m²))
Be aware that refrigerant may not contain
an odour, highly recommended to ensure
suitable flammable refrigerant gas
detectors are present, operating and able
to warn of a leak.

material may cause product damage,
burst and serious injury.
Do not pierce or burn as the appliance is
pressurized. Do not expose the appliance
to heat, flame, sparks, or other sources
of ignition. Else it may explode and cause
injury or death.
Do not install the unit in a potentially
explosive or flammable atmosphere.
Failure to do so could result in fire.
Do not insert your fingers or other
objects into the air conditioner
indoor or outdoor unit, rotating
parts may cause injury.
Do not touch the outdoor unit during
lightning, it may cause electric shock.
Do not expose yourself directly to cold air
for a long period to avoid excess cooling.
Do not sit or step on the unit, you
may fall down accidentally.
Remote control
Do not allow infants and small children
to play with the remote control to prevent
them from accidentally swallowing the
batteries.
Power supply
Do not use a modified
cord, joint cord, extension
cord or unspecified cord
to prevent overheating
and fire.
To prevent overheating, fire or electric
shock:
• Do not share the same power outlet with
other equipment.
• Do not operate with wet hands.
• Do not over bend the power supply
cord.
• Do not operate or stop the unit by
inserting or pulling out the power plug.
If the supply cord is damaged, it must be
replaced by the manufacturer, service
agent or similarly qualified persons in
order to avoid a hazard.
It is strongly recommended to be installed
with Earth Leakage Circuit Breaker
(ELCB) or Residual Current Device
(RCD) to prevent electric shock or fire.
To prevent overheating, fire or electric
shock:
• Insert the power plug properly.
• Dust on the power plug should be
periodically wiped with a dry cloth.
Stop using the product if any abnormality/
failure occurs and disconnect the power
plug or turn off the power switch and
breaker.
(Risk of smoke/fire/electric shock)
Examples of abnormality/failure
• The ELCB trips frequently.
• Burning smell is observed.
• Abnormal noise or vibration of the unit
is observed.
• Water leaks from the indoor unit.
• Power cord or plug becomes abnormally
hot.
• Fan speed cannot be controlled.
• The unit stops running immediately
even if it is switched on for operation.
• The fan does not stop even if the
operation is stopped.
Contact your local dealer immediately for
maintenance/repair.
This equipment must be earthed to
prevent electrical shock or fire.

Safety precautions
Prevent electric shock by switching off
the power supply and unplug:
- Before cleaning or servicing,
- When extended non-use, or
- During abnormally strong lightning
activity.
Precaution for using R32 refrigerant
Pay careful attention to the following points when
operating the appliances and dealing with different
refrigerants.
Since the working pressure is higher than
that of refrigerant R22 models, some of
the piping and installation and service
tools are special.
Especially, when replacing a refrigerant
R22 model with a new refrigerant R32
model, always replace the conventional
piping and flare nuts with the R32 and
R410A piping and flare nuts on the
outdoor unit side.
For R32 and R410A, the same flare nut
on the outdoor unit side and pipe can be
used.
Models that use refrigerant R32 and
R410A have a different charging port
thread diameter to prevent erroneous
charging with refrigerant R22 and for
safety.
Therefore, check beforehand. [The
charging port thread diameter for R32
and R410A is 12.7 mm (1/2 inch).]
Be more careful than R22 so that foreign
matter (oil, water, etc.) does not enter the
piping.
Also, when storing the piping, securely
seal the opening by pinching, taping, etc.
(Handling of R32 is similar to R410A.)
This appliance shall be stored in a well
ventilated area.
This appliance shall be stored in a room
without continuously operating open
flames and ignition sources.
This appliance shall be stored so as
to prevent mechanical damage from
occurring.
CAUTION
Indoor unit and outdoor unit
Do not wash the indoor unit with water,
benzine, thinner or scouring powder to
avoid damage or corrosion at the unit.
Do not use for preservation of precise
equipment, food, animals, plants, artwork
or other objects. This may cause quality
deterioration, etc.
Do not use any combustible equipment
in front of the airflow outlet to avoid fire
propagation.
Do not expose plants or pet directly to
airflow to avoid injury, etc.
Do not touch the sharp
aluminium fin, sharp parts may
cause injury.
Do not switch ON the indoor unit when
waxing the floor. After waxing, aerate the
room properly before operating the unit.
Do not install the unit in oily and smoky
areas to prevent damage to the unit.
Do not dismantle the unit for cleaning
purpose to avoid injury.
Do not step onto an unstable bench
when cleaning the unit to avoid injury.
Do not place a vase or water container
on the unit. Water may enter the unit and
degrade the insulation. This may cause
an electric shock.
Do not open window or door for long time
during operation, it may lead to inefficient
power usage and uncomfortable
temperature changes.

EnglishSafety precautions
Prevent water leakage by ensuring
drainage pipe is:
- Connected properly,
-Kept clear of gutters and containers,
or
- Not immersed in water
After a long period of use or use with any
combustible equipment, aerate the
room regularly.
After a long period of use, make sure the
installation rack does not deteriorate to
prevent the unit from falling down.
