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 an item for which caution must be exercised.
The pictogram shows the item to which attention must be paid.
This symbol indicatesaprohibited action.
The prohibited item or action is shown inside or near the symbol.
This symbol indicates an action that must be taken, or an instruction.
The instruction is shown inside 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.

1.2.1 Caution in Repair
Warning
Be sure to disconnect the power cable plug from the plug socket before disassembling the equipment for
a repair.
Working on the equipment that is connected toapower supply can cause an electrical shook.
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 discharges during the repair work, do not touch the discharging refrigerant gas .The
refrigerant gas can cause frostbite.
When disconnecting the suction or discharge pipe of the compressor at the welded section, release the
refrigerant gas completely at a well-ventilated place first.
If there isagas remaining inside the compressor , the refrigerant gas or refrigerating machine oil
discharges when the pipe is disconnected, and it can cause injury.
If the refrigerant gas leaks during the repair work, ventilate the area. The refrigerant gas can 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 can
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 can cause an electrical shock or
fire.

Introduction
Domestic air conditioner
Warning
Do not repair the electrical components with wet hands . Working on the equipment with wet hands can
cause an electrical shock
Do not clean the air conditioner by splashing water. Washing the unit with water can cause an electrical
shock.
Be sure to provide the grounding when repairing the equipment in a humid or wet place, to avoid
electrical
shock.
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.
Do not tilt the unit when removing it. The water inside the unit can spill and wet the furniture and floor.
Be sure to check that the refrigerating cycle section has cooled down sufficiently before conducting
repair
work. Working on the unit when the refrigerating cycle section is hot can cause burns.
Use the welder in a well-ventilated place. Using the welder in an enclosed room can cause oxygen
deficiency.
1.2.2 Cautions Regarding Products after Repair
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 can
cause an electrical shock, excessive heat generation or fire.
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 can fall and cause injury.
Be sure to install the product correctly by using the provided standard installation frame.
Incorrect use of the installation frame and improper installation can cause the equipment to fall, resulting
in injury.
For
integral
units only
Be sure to install the product securely in the installation frame mounted on a window frame.
If the unit is not securely mounted, it can fall and cause injury.
For
integral
units only

Introduction
Domestic air conditioner
Warning
Be sure to use an exclusive power circuit for the equipment, and follow the 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 can cause an electrical shock or fire.
Be sure to use the specified cable to connect 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 can cause excessive heat generation or fire.
When connecting the cable 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 can cause an electrical shock,
excessive heat generation or fire.
Do not damage or modify the power cable.
Damaged or modified power cable can cause an electrical shock or fire. Placing heavy items on the
power cable, and heating or pulling the power cable can damage the cable.
Do not mix air or gas other than the specified refrigerant (R-410A / R22) 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 leak and repair it before charging the refrigerant. After
charging refrigerant, make sure that there is no refrigerant leak.
If the leak 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 can generate toxic gases when it contacts flames, such as fan and other heaters,
stoves and ranges.
.
When replacing the coin battery in the remote controller, be sure to disposed of the old battery to prevent
children from swallowing it.
If a child swallows the coin battery, see a doctor immediately.

Introduction
Domestic air conditioner
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 a combustible gas leaks and remains around the unit, it can cause a fire.
Be sure to install the packing and seal on the installation frame properly. If the packing and seal are not
installed properly, water can enter the room and wet the furniture and floor.
1.2.3 Inspection after Repair
Warning
Check to make sure that the power cable plug is not dirty or loose, then insert the plug into a power outlet
all the way.
If the plug has dust or loose connection, it can cause an electrical shock or fire.
If the power cable and lead wires have scratches or deteriorated, be sure to replace them.
Damaged cable and wires can cause an electrical shock, excessive heat generation or fire.
Warning
Do not use a joined power cable or extension cable, or share the same power outlet with other electrical
appliances since it can cause an electrical shock, excessive heat generation or fire.

Introduction
Domestic air conditioner
Caution
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 can cause excessive
heat generation, fire or an electrical shock.
If the installation platform or frame has corroded, replace it. Corroded installation platform or frame can
cause the unit to fall, resulting in injury.
Check the grounding, and repair it if the equipment is not properly grounded. Improper grounding can
cause an electrical shock.
Be sure to measure the insulation resistance after the repair, and make sure that the resistance is 1 M
ohm or higher.
Faulty insulation can cause an electrical shock.
Be sure to check the drainage of the indoor unit after the repair.
Faulty drainage can cause the water to enter the room and wet the furniture and floor.
