Part 1 General Information
1. Safety Precautions
1.1 Cautions in Repair
To prevent injury to the user or other people and property damage, the following instructions must be followed.
nIncorrect operation due to ignoring instruction will cause harm or damage. The seriousness is classified by the follow-
ing indications.
This symbol indicates the possibility of death or serious injury.
This symbol indicates the possibility of injury or damage to properties only.
nMeanings of symbols used in this manual are as shown below.
Be sure not to do.
Be sure to follow the instruction.
Dangerous Voltage
Be sure to disconnect the power cable plug from the plug socket before disas-
sembling the equipment for a repair.Internal components and circuit boards are at
main potential when the equipment is connected to the power cables. This volt-
age is extremely dangerous and may cause death or severe injury if come in con-
tact with it.
Do not touch the discharging refrigerant gas during the repair work.
The discharging refrigerant gas.The refrigerant gas can cause frostbite.
Release the refrigerant gas completely at a well-ventilated place first.
Otherwise, when the pipe is disconnected, refrigerant gas or refrigerating
machine oil discharges and it Can cause injury.
When the refrigerant gas leaks during work, execute ventilation. If the refrigerant
gas touches to a fire, poisonous gas generates. A case of leakage of the refriger-
ant and the closed room full with gas is dangerous because a shortage of oxygen
occurs. Be sure to execute ventilation.
When removing the front panel or cabinet, execute short-circuit and discharge
between high voltage capacitor terminals. If discharge is not executed, an electric
shock is caused by high voltage resulted in a death or injury.
Do not turn the air-conditioner ON or OFF by plugging or unplugging the power
plug. There is risk of fire or electrical shock.

Part 1 General Information
Do not turn on the breaker under condition that front panel and cabinet are
removed.
Be sure to earth the air conditioner with an earthing conductor connected to the
earthing terminal.
Conduct repair works after checking that the refrigerating cycle section has
cooled down sufficiently. Otherwise, working on the unit, the hot refrigerating
cycle section can cause burns.
Do not tilt the unit when removing panels. Otherwise, the water inside the unit
can spill and wet floor.
Do not use the welder in a well-ventilated place. Using the welder in an enclosed
room can cause oxygen deficiency.
Be sure to turn off power switch before connect or disconnect connector, or parts
damage may be occurred.
Do not use a defective or underrated circuit breaker. Use the correctly rated
breaker and fuse. Otherwise there is a risk of fire or electric shock.
Install the panel and the cover of control box securely. Otherwise there is risk of
fire or electric shock due to dust, water etc.
Indoor/outdoor wiring connections must be secured tightly and the cable should
be routed properly so that there is no force pulling the cable from the connection
terminals. Improper or loose connections can cause heat generation or fire.
Do not touch, operate, or repaire the product with wet hands. Hoding the plug by
hand when taking out. Otherwise there is risk of electric shock or fire.
Use a vacuum pump or Inert (nitrogen) gas when doing leakage test or air
purge. Do not compress air or Oxygen and Do not use Flammable gases.
Otherwise, it may cause fire or explosion.
- There is the risk of death, injury, fire or explosion.

Part 1 General Information
1.2 Inspections after Repair
Check to see if the parts are mounted correctly and wires are connected.
Improper installation and connections can cause an electric shock or an injury.
Check the installation platform or frame has corroded. Corroded installation plat-
form or frame can cause the unit to fall, resulting in injury.
Be sure to check the earth wire is correctly connected.
After the work has finished, be sure to do an insulation tset to check the resis-
tance is 2[Mohm] or more between the charge section and the non-charge metal
section (Earth position). If the resistance value is low, a disaster such as a leak or
electric shock is caused at userʼs side.
Check the drainage of the indoor unit after the repair. If drainage is faulty the
water to enter the room and wet floor.
Check to see if the power cable plug is not dirty or loose. If the plug is dust or
loose it can cause an electrical shock or fire.
Do not use a joined power cable or extension cable, or share the same power
outlet with other electrical appliances. otherwise, it can cause an electrical shock,
excessive heat generation or fire.
Do not insert hands or other objects through the air inlet or outlet while the prod-
uct is operating. There are sharp and moving parts that could cause personal
injury.
Do not block the inlet or outlet of air flow. It may cause product failure
