1 PRECAUTIONS FOR SAFETY
DANGER
• Do not attempt to install this unit by yourself.
This unit requires quali¿ed installer.
• Do not attempt to repair the unit by yourself.
This unit has no components which you can repair.
• Opening or removing the cover will expose you to
dangerous voltage.
• Turning off the power supply will not prevent potential
electric shock.
The manufacturer shall not assume any liability for the damage caused by not
observing the description of this manual.
WARNING
General
• Carefully read Owner’s Manual before starting the air conditioner. There are
many important things to keep in mind for daily operation.
• Ask for installation to be performed by the dealer or a professional. Only a
quali¿ed installer (*1) is able to install an air conditioner. If a non-quali¿ed
person installs an air conditioner, it may result in problems such as ¿re,
electric shock, injury, water leakage, noise and vibration.
• Do not use any refrigerant different from the one speci¿ed for complement or
replacement. Otherwise, abnormally high pressure may be generated in the
refrigeration cycle, which may result in a failure or explosion of the product or
an injury to your body.
• Places where the operation sound of the outdoor unit may cause a
disturbance. (Especially at the boundary line with a neighbour, install the air
conditioner while considering the noise.)
• This appliance is intended to be used by expert or trained users in shops, in
light industry, or for commercial use by lay persons.
Transportation and storage
• To transport the air conditioner, wear shoes with protective toe caps,
protective gloves, and other protective clothing.
• To transport the air conditioner, do not take hold of the bands around the
packing carton. You may injure yourself if the bands should break.
• Before stacking the packing cartons for storage or transportation, heed the
precautions written on the packing cartons. Failure to heed the precautions
may cause the stack to collapse.
• The air conditioner must be transported in stable condition. If any part of the
product broken, contact your dealer.

OM_1121250207_EN.indd 5 6/8/2562 BE 14:52
• When the air conditioner must be transported by hand, carry it by two or
more people.
Installation
• Only a quali¿ed installer (*1) or quali¿ed service person (*1) is allowed to
carry out the electrical work of the air conditioner. Under no circumstances
must this work be done by an unquali¿ed individual since failure to carry out
the work properly may result in electric shocks and/or electrical leaks.
• After the installation work has been completed, have the installer explain
about the circuit breaker positions. In the event that trouble has occurred in
the air conditioner, set the circuit breaker to the OFF position, and contact a
quali¿ed service person (*1).
• If the unit is installed 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 de¿ciency accident.
• Do not install the air conditioner in a location that may be subject to a risk
of exposure to a combustible gas. If a combustible gas leaks and becomes
concentrated around the unit, a ¿re may occur.
• Use the company-speci¿ed products for the separately purchased parts. Use
of non-speci¿ed products may result in ¿re, electric shock, water leakage or
other trouble. Have the installation performed by a professional.
• Con¿rm that earthing is performed correctly.
Operation
• Before opening the front panel of the indoor unit or service panel of the
outdoor unit, set the circuit breaker to the OFF position. Failure to set the
circuit breaker to the OFF position may result in electric shocks through
contact with the interior parts. Only a quali¿ed installer (*1) or quali¿ed
service person (*1) is allowed to remove the front panel of the indoor unit or
service panel of the outdoor unit and do the work required.
• Inside the air conditioner are high-voltage areas and rotating parts. Due to
the danger of electric shocks or of your ¿ngers or physical objects becoming
trapped in the rotating parts, do not remove the front panel of the indoor unit
or service panel of the outdoor unit. When work involving the removal of
these parts is required, contact a quali¿ed installer (*1) or quali¿ed service
person (*1).
• Do not move or repair any unit by yourself. Since there is high voltage
inside the unit, you may get electric shock when the cover and main unit is
removed.
• Use of a stand more than 50 cm high to clean the ¿lter of the indoor unit or to
carry out other such jobs constitutes working at heights. Due to the danger of
falling off the stand and injuring yourself while working at heights, this kind of
work should not be done by unquali¿ed individuals. When this kind of work
must be carried out, do not do it yourself but ask a quali¿ed installer (*1) or
quali¿ed service person (*1) to do it for you.

you do so. If the ¿n must be touched, do not touch it yourself but contact a
quali¿ed installer (*1) or quali¿ed service person (*1).
• Do not climb onto or place objects on top of the outdoor unit. You may fall or
the objects may fall off of the outdoor unit and result in injury.
• 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.
• When the air conditioner is operated with a combustion appliance in the
same place, ventilate the room suf¿ciently. Poor ventilation causes oxygen
shortage.
• When the air conditioner is used in a closed room, suf¿ciently ventilate the
room. Poor ventilation causes oxygen shortage.
• Do not expose your body to cool air directly for a long time and do not cool
yourself excessively. Doing so may result in deteriorated physical condition
and ill health.
• Do not insert your ¿nger or a stick into the air intake or discharge. Doing so
may result injury as the fan is rotating at high speed inside the unit.
• Consult the shop where you purchased the air conditioner if air conditioning
(cooling and heating) is not performed properly as a refrigerant leakage may
be the cause. Con¿rm the repair details with a quali¿ed service person (*1)
when the repair includes additional charging of the refrigerant.
• Stop running the air conditioner and turn off the breaker before cleaning.
Otherwise, injury may result as the fan is rotating at high speed inside the
unit.
Repairs
• If there is any kind of trouble (such as when an error display has appeared,
there is a smell of burning, abnormal sounds are heard, the air conditioner
fails to cool or heat or water is leaking) has occurred in the air conditioner,
do not touch the air conditioner yourself but set the circuit breaker to the
OFF position, and contact a quali¿ed service person (*1). Take steps to
ensure that the power will not be turned on (by marking “out of service”
near the circuit breaker, for instance) until quali¿ed service person (*1)
arrives. Continuing to use the air conditioner in the trouble status may cause
mechanical problems to escalate or result in electric shocks or other trouble.
• If the fan grille is damaged, do not approach the outdoor unit but set the
circuit breaker to the OFF position, and contact a quali¿ed service person
(*1) to have the repairs done. Do not set the circuit breaker to the ON
position until the repairs are completed.
• If there is a danger of the indoor unit’s falling, do not approach the indoor
unit but set the circuit breaker to the OFF position, and contact a quali¿ed
installer (*1) or a quali¿ed service person (*1) to re¿t the unit. Do not set the
circuit breaker to the ON position until the unit has been re¿tted.
