Safety precautions
Prevent electric shock by switching off

- 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

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
