WARNING
| Before troubleshooting or repair work, check the earth wire is connected to the earth | |
| terminals of the main unit, otherwise an electric shock is caused when a leak occurs. | |
Check earth wires. | If the earth wire is not correctly connected, contact an electric engineer for rework. | |

| Do not modify the products. | |
| Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury. | |
Prohibition of modification. |

| For spare parts, use those specified (∗ ). | |
| If unspecified parts are used, a fire or electric shock may be caused. | |
Use specified parts. | ∗ : For details, refer to the parts list. | |

Insulating measures |
|
When repairing the refrigerating cycle, take the following measures.
1)Be attentive to fire around the cycle. When using a gas stove, etc, be sure to put out fire before work; otherwise the oil mixed with refrigerant gas may catch fire.
| 2) Do not use a welder in the closed room. |
No fire | When using it without ventilation, carbon monoxide poisoning may be caused. |
3)Do not bring inflammables close to the refrigerant cycle, otherwise fire of the welder may catch the inflammables.
| Check the used refrigerant name and use tools and materials of the parts which | |
| match with it. | |
| For the products which use R410A refrigerant, the refrigerant name is indicated at a | |
| position on the outdoor unit where is easy to see. To prevent | |
| service port is changed from one of the former R22. | |
| For an air conditioner which uses R410A, never use other refrigerant than R410A. | |
| For an air conditioner which uses other refrigerant (R22, etc.), never use R410A. | |
| If different types of refrigerant are mixed, abnormal high pressure generates in the | |
| refrigerating cycle and an injury due to breakage may be caused. | |
| Do not charge refrigerant additionally. | |
| If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in | |
| the refrigerating cycle changes resulted in change of air conditioner characteristics or | |
| refrigerant over the specified standard amount is charged and an abnormal high pressure is | |
| applied to the inside of the refrigerating cycle resulted in cause of breakage or injury. | |
| Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute | |
Refrigerant | vacuuming, and then newly recharge the specified amount of liquid refrigerant. | |
In this time, never charge the refrigerant over the specified amount. | ||
| ||
| When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant | |
| or air other than R410A into the specified refrigerant. | |
| If air or others is mixed with the refrigerant, abnormal high pressure generates in the | |
| refrigerating cycle resulted in cause of injury due to breakage. | |
| After installation work, check the refrigerant gas does not leak. | |
| If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire | |
| such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous. | |
| Never recover the refrigerant into the outdoor unit. | |
| When the equipment is moved or repaired, be sure to recover the refrigerant with | |
| recovering device. The refrigerant cannot be recovered in the outdoor unit; otherwise a | |
| serious accident such as breakage or injury is caused. | |
|
| |
| After repair work, surely assemble the disassembled parts, and connect and lead the | |
| removed wires as before. Perform the work so that the cabinet or panel does not | |
| catch the inner wires. | |
Assembly/Cabling | If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or | |
fire is caused at user’s side. | ||
