Precautions for Safety
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 qualified installer (*1) is able to install an
air conditioner. If a non-qualified person installs an air conditioner, it may result in problems such as fire, electric
shock, injury, water leakage, noise and vibration.
• Do not use any refrigerant different from the one specified 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.)
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.
• When the air conditioner must be transported by hand, carry it by two or more people.
Installation
• Only a qualified installer(*1) or qualified 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 unqualified 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 service
person.
• 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 deficiency accident.
• Do not install the air conditioner in a location that may be subject to a risk of expire to a combustible gas. If a
combustible gas leaks and becomes concentrated around the unit, a fire may occur.
• Use the company-specified products for the separately purchased parts. Use of non-specified products may result in
fire, electric shock, water leakage or other trouble. Have the installation performed by a professional.
• Confirm that earthing is performed correctly.
Operation
• Before opening the intake grille 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 qualified installer(*1) or qualified service person(*1) is allowed to remove the intake grille 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
fingers or physical objects becoming trapped in the rotating parts, do not remove service panel of the outdoor unit.
When work involving the removal of these parts is required, contact a qualified installer or a qualified service person.
• Do not move or repair any unit by yourself. Since there is high voltage inside the unit, you may get electric shock
when removing the cover and main unit.
• Use of a stand more than 50 cm high to clean the filter 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 unqualified individuals. When this kind of work must be carried out, do not do it yourself
but ask a qualified installer or a qualified service person to do it for you.
• Do not touch the aluminum fin of the outdoor unit. You may injure yourself if you do so. If the fin must be touched, do
not touch it yourself but contact a qualified installer or a qualified service person.
• 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.
