The instruction is shown in the illustration or near the symbol.

1.1 Warnings and Cautions Regarding Safety of Workers

Warning

Do not store the equipment in a room with successive fire sources (e.g., naked flame, gas appliance, electric heater).

Be sure to disconnect the power cable plug from the plug socket before disassembling the equipment for repair.

Working on the equipment that is connected to the power supply may cause an electrical shock. If it is necessary to supply power to the equipment to conduct the repair or inspecting the circuits, do not touch any electrically charged sections of the equipment.

If the refrigerant gas is discharged during the repair work, do not touch the discharged refrigerant gas.

The refrigerant gas may cause frostbite.

When disconnecting the suction or discharge pipe of the compressor at the welded section, evacuate the refrigerant gas completely at a wellventilated place first.

If there is gas remaining inside the compressor, the refrigerant gas or refrigerating machine oil discharges when the pipe is disconnected, and it may cause injury.

If the refrigerant gas leaks during the repair work, ventilate the area.

The refrigerant gas may generate toxic gases when it contacts flames.

Be sure to discharge the capacitor completely before conducting repair work.

The step-up capacitor supplies high-voltage electricity to the electrical components of the outdoor unit. A charged capacitor may cause an electrical shock.

SiBE041011EC Safety Cautions

Do not start or stop the air conditioner operation by plugging or unplugging the power cable plug.

Plugging or unplugging the power cable plug to operate the equipment may cause an electrical shock or fire.

Be sure to wear a safety helmet, gloves, and a safety belt when working at a high place (more than 2 m).

Insufficient safety measures may cause a fall accident.

In case of R-32 / R-410A refrigerant models, be sure to use pipes, flare nuts and tools for the exclusive use of the R-32 / R-410A refrigerant.

The use of materials for R-22 refrigerant models may cause a serious accident such as a damage of refrigerant cycle as well as an equipment failure.

Do not mix air or gas other than the specified refrigerant (R-32 / R-410A / R-22) in the refrigerant system.

If air enters the refrigerating system, an excessively high pressure results, causing equipment damage and injury.

Warning

Caution

Do not repair the electrical components with wet hands.

Working on the equipment with wet hands may cause an electrical shock.

Do not clean the air conditioner by splashing water.

Washing the unit with water may cause an electrical shock.

Be sure to provide the grounding when repairing the equipment in a humid or wet place, to avoid electrical shocks.

Be sure to turn off the power switch and unplug the power cable when cleaning the equipment.

The internal fan rotates at a high speed, and may cause injury.

Be sure to conduct repair work with appropriate tools.

The use of inappropriate tools may cause injury.

Be sure to check that the refrigerating cycle section has cooled down enough before conducting repair work.

Working on the unit when the refrigerating cycle section is hot may cause burns.

1.2 Warnings and Cautions Regarding Safety of Users

Use the welder in a well-ventilated place.

Using the welder in an enclosed room may cause oxygen deficiency.

Caution

Warning

Do not store the equipment in a room with successive fire sources (e.g., naked flame, gas appliance, electric heater).

Be sure to use parts listed in the service parts list of the applicable model and appropriate tools to conduct repair work. Never attempt to modify the equipment.

The use of inappropriate parts or tools may cause an electrical shock, excessive heat generation or fire.

If the power cable and lead wires have scratches or deteriorated, be sure to replace them.

Damaged cable and wires may cause an electrical shock, excessive heat generation or fire.

Do not use a joined power cable or extension cable, or share the same power outlet with other electrical appliances, since it may cause an electrical shock, excessive heat generation or fire.

Be sure to use an exclusive power circuit for the equipment, and follow the local technical standards related to the electrical equipment, the internal wiring regulations, and the instruction manual for installation when conducting electrical work.

Insufficient power circuit capacity and improper electrical work may cause an electrical shock or fire.

Be sure to use the specified cable for wiring between the indoor and outdoor units.

Make the connections securely and route the cable properly so that there is no force pulling the cable at the connection terminals. Improper connections may cause excessive heat generation or fire.

When wiring between the indoor and outdoor units, make sure that the terminal cover does not lift off or dismount because of the cable.

If the cover is not mounted properly, the terminal connection section may cause an electrical shock, excessive heat generation or fire.

Do not damage or modify the power cable.

Damaged or modified power cable may cause an electrical shock or fire. Placing heavy items on the power cable, and heating or pulling the power cable may damage the cable.

SiBE041011EC Safety Cautions

viii

Do not mix air or gas other than the specified refrigerant (R-32 / R-410A / R-22) in the refrigerant system.

If air enters the refrigerating system, an excessively high pressure results, causing equipment damage and injury.

If the refrigerant gas leaks, be sure to locate the leaking point and repair it before charging the refrigerant. After charging refrigerant, make sure that there is no refrigerant leak.

If the leaking point cannot be located and the repair work must be stopped, be sure to perform pump-down and close the service valve, to prevent the refrigerant gas from leaking into the room. The refrigerant gas itself is harmless, but it may generate toxic gases when it contacts flames, such as fan and other heaters, stoves and ranges.

When relocating the equipment, make sure that the new installation site has sufficient strength to withstand the weight of the equipment.

If the installation site does not have sufficient strength and if the installation work is not conducted securely, the equipment may fall and cause injury.

Check to make sure that the power cable plug is not dirty or loose, then insert the plug into a power outlet securely.

If the plug has dust or loose connection, it may cause an electrical shock or fire.

Be sure to install the product correctly by using the provided standard installation frame.

Incorrect use of the installation frame and improper installation may cause the equipment to fall, resulting in injury.

For unitary type only

Be sure to install the product securely in the installation frame mounted on the window frame.

If the unit is not securely mounted, it may fall and cause injury.

For unitary type only

When replacing the coin battery in the remote controller, be sure to dispose of the old battery to prevent children from swallowing it.

If a child swallows the coin battery, see a doctor immediately.

Warning

Caution

Installation of a leakage breaker is necessary in some cases depending on the conditions of the installation site, to prevent electrical shocks.

Do not install the equipment in a place where there is a possibility of combustible gas leaks.

If the combustible gas leaks and remains around the unit, it may cause a fire.

Safety Cautions SiBE041011EC

Check to see if the parts and wires are mounted and connected properly, and if the connections at the soldered or crimped terminals are secure.

Improper installation and connections may cause excessive heat generation, fire or an electrical shock.

If the installation platform or frame has corroded, replace it.

Corroded installation platform or frame may cause the unit to fall, resulting in injury.

Check the grounding, and repair it if the equipment is not properly grounded.

Improper grounding may cause an electrical shock.

Be sure to measure the insulation resistance after the repair, and make sure that the resistance is 1 MΩ or higher.

Faulty insulation may cause an electrical shock.

Be sure to check the drainage of the indoor unit after the repair.

Faulty drainage may cause the water to enter the room and wet the furniture and floor.

Do not tilt the unit when removing it.

The water inside the unit may spill and wet the furniture and floor.
