The caution items are classified into “ Warning” and “ Caution”. The “ Warning”

items are especially important since they can lead to death or serious injury if they are not

followed closely. The “ Caution” items can also lead to serious accidents under some

conditions if they are not followed. Therefore, be sure to observe all the safety caution items

described below.

About the pictograms

This symbol indicates the item for which caution must be exercised.

The pictogram shows the item to which attention must be paid.

This symbol indicates the prohibited action.

The prohibited item or action is shown in the illustration or near the symbol.

This symbol indicates the action that must be taken, or the instruction.

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

After the repair work is complete, be sure to conduct a test operation to ensure that the

equipment operates normally, and explain the cautions for operating the product to the

customer.

1.1.1 Cautions Regarding Safety of Workers

Warning

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 well-ventilated

place first.

If there is a 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.

The step-up capacitor supplies high-voltage electricity to the electrical

components of the outdoor unit.

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

A charged capacitor may cause an electrical shock.

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.

Introduction SiBE281013

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-410A refrigerant models, be sure to use pipes, flare nuts and tools

for the exclusive use of the 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.

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 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.

Use the welder in a well-ventilated place.

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

SiBE281013 Introduction

1.1.2 Cautions Regarding Safety of Users

Warning

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.

Do not mix air or gas other than the specified refrigerant (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.

Introduction SiBE281013

vii

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

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.

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.
