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 qualifi ed 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 fi re.
To prevent overheating, fi re 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/fi re/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 fi re.
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
The basic installation work procedures are the same as
conventional refrigerant (R410A, R22) models.
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 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.)
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.
