•Be sure to read “THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY” before installing the air conditioner.

•Be sure to observe the warnings and cautions specified here as they include important items related to safety.

•After reading this manual, be sure to keep it together with the OPERATING INSTRUCTIONS for future reference.

•Equipment complying with IEC/EN 61000-3-12.

WARNING (Could lead to death, serious injury, etc.)

nDo not install the unit by yourself (user).

Incompleteinstallationcouldcausefire orelectricshock,injuryduetotheunit falling, or leakage of water. Consult the dealer from whom you purchased the unit or a qualified installer.

nPerform the installation securely referring to the installation manual.

Incomplete installation could cause fire, electric shock, injury due to the unit falling, or leakage of water.

nWhen installing the unit, use appropriate protective equipment and tools for safety.

Failure to do so could cause injury.

nInstall the unit securely in a place which can bear the weight of the unit.

If the installation location cannot bear the weight of the unit, the unit could fall causing injury.

nElectricalworkshouldbeperformedbyaqualified,experiencedelectrician, according to the installation manual. Be sure to use an exclusive circuit. Do not connect other electrical appliances to the circuit.

If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock.

nDo not damage the wires by applying excessive pressure with parts or screws.

Damaged wires could cause fire or electric shock.

nBe sure to cut off the main power in case of setting up the indoor P.C. board or wiring works.

Failure to do so could cause electric shock.

nUse the specified wires to connect the indoor and outdoor units securely and attach the wires firmly to the terminal block connecting sections so the stress of the wires is not applied to the sections. Do not extend the wires, or use intermediate connection.

Incomplete connecting and securing could cause fire.

nDo not install the unit in a place where inflammable gas may leak.

If gas leaks and accumulates in the area around the unit, it could cause an explosion.

nDonotuse intermediate connectionofthe powercordor theextension cord and do not connect many devices to one AC outlet.

It could cause a fire or an electric shock due to defective contact, defective insulation, exceeding the permissible current, etc.

nBe sure to use the parts provided or specified parts for the installation work.

The use of defective parts could cause an injury or leakage of water due to a fire, an electric shock, the unit falling, etc.

nWhen plugging the power supply plug into the outlet, make sure that there is no dust, clogging, or loose parts in both the outlet and the plug. Make sure that the power supply plug is pushed completely into the outlet.

If there is dust, clogging, or loose parts on the power supply plug or the outlet, it could cause electric shock or fire. If loose parts are found on the power supply plug, replace it.

nAttach the electrical cover to the indoor unit and the service panel

to the outdoor unit securely.

If the electrical cover of the indoor unit and/or the service panel of the outdoor unit are not attached securely, it could result in a fire or an electric shock due to dust, water, etc.

nWhen installing, relocating, or servicing the unit, make sure that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit.

Any presence of foreign substance such as air can cause abnormal pressure rise and may result in explosion or injury. The use of any refrigerant other than that specified for the system will cause mechanical failure, system malfunction, or unit breakdown. In the worst case, this could lead to a serious impediment to securing product safety.

nDo not discharge the refrigerant into the atmosphere. If refrigerant leaks during installation, ventilate the room.

If refrigerant comes in contact with a fire, harmful gas could be generated. Refrigerant leakage may cause suffocation. Provide ventilation in accordance with EN378-1.

nCheck that the refrigerant gas does not leak after installation has been completed.

If refrigerant gas leaks indoors, and comes into contact with the flame of a fan heater, space heater, stove, etc., harmful substances will be generated.

nUse appropriate tools and piping materials for installation.

The pressure of R410A is 1.6 times more than R22. Not using appropriate tools or materials and incomplete installation could cause the pipes to burst or injury.

nWhen pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.

If the refrigerant pipes are disconnected while the compressor is running and the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle could become abnormally high. This could cause the pipes to burst or injury.

nWhen installing the unit, securely connect the refrigerant pipes before starting the compressor.

If the compressor is started before the refrigerant pipes are connected and when the stop valve is open, air could be drawn in and the pressure in the refrigeration cycle could become abnormally high. This could cause the pipes to burst or injury.

nFasten a flare nut with a torque wrench as specified in this manual.

If fastened too tight, a flare nut may break after a long period and cause refrigerant leakage.

nThe unit shall be installed in accordance with national wiring regulations.

nEarth the unit correctly.

Do not connect the earth to a gas pipe, water pipe, lightning rod or telephone earth. Defective earthing could cause electric shock.

nBe sure to install an earth leakage breaker.

Failure to install an earth leakage breaker may result in electric shock or fire.

CAUTION (Could lead to serious injury in particular environments when operated incorrectly.)

nPerform the drainage/piping work securely according to the installation manual.

If there is defect in the drainage/piping work, water could drop from the unit, soaking and damaging household goods.

nDo not touch the air inlet or the aluminum fins of the outdoor unit.

This could cause injury.

nDo not install the outdoor unit where small animals may live.

If small animals enter and touch the electric parts inside the unit, it could cause a malfunction, smoke emission, or fire. Also, advise user to keep the area around the unit clean.
