ing indications.
This symbol indicates the possibility of death or serious injury.
This symbol indicates the possibility of injury or damage to property only.
■ Meanings 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 high
voltage is extremely dangerous and may cause death or severe injury if come in
contact with it.
Do not touch the discharging refrigerant gas during the repair work.
The discharging refrigerant gas can cause frostbite.
Release the refrigerant gas completely in 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, ventilate the area. If the refrigerant
gas comes in contact with fire, a poisonous gas poisonous gas generates.
Leakage of the refrigerant closed room full of gas is dangerous because a short-
age of oxygen occurs. Be sure to ventilate the area.
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 resulting 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.
