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 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 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.

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.

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.
