1 PRECAUTIONS FOR SAFETY
WARNING
General
• Carefully read Owner’s Manual before starting the air conditioner.
There are many important things to keep in mind for daily operation.
Transportation and storage
• When transporting the air conditioner, wear shoes with additional protective toe caps.
• When transporting the air conditioner, do not take hold of the bands around the packing carton.
You may injure yourself if the bands should break.
• When 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.
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 you install the unit 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.
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
the intake grille of the indoor unit or 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.
• 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, be careful of ventilation to let fresh air enter
the room. Poor ventilation causes oxygen shortage.
• When the air conditioner is used in a closed room, be careful of sufficient ventilation of the room.
Poor ventilation causes oxygen shortage.
Repairs
• When you have noticed that some 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 qualified service person.
Take steps to ensure that the power will not be turned on (by marking “out of service” near the circuit breaker, for instance) until
qualified service person arrives. Continuing to use the air conditioner in the trouble status may cause mechanical problems to
escalate or result in electric shocks, etc.
• If you have discovered that the fan grille is damaged, do not approach the outdoor unit but set the circuit breaker to the OFF
position, and contact a qualified service person to have the repairs done.
Do not set the circuit breaker to the ON position until the repairs are completed.
• If you have discovered that 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 qualified installer or a qualified service person to refit the unit.
Do not set the circuit breaker to the ON position until the unit has been refitted.
• If you have discovered that there is a danger of the outdoor unit’s toppling over, do not approach the outdoor unit but set the
circuit breaker to the OFF position, and contact a qualified installer or a qualified service person to have the improvements or
refitting done. Do not set the circuit breaker to the ON position until the improvements or refitting is completed.
