Insulating measures
When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because the oil that coats the pipes may otherwise burn.
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
No fire | refrigerant gas may catch fire. |
2) Do not use a welder in the closed room. | |
| 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.
| The refrigerant used by this air conditioner is the R410A. | |
|
| |
| 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 | |
| Do not use any refrigerant different from the one specified for complement or replacement. | |
| Otherwise, abnormally high pressure may be generated in the refrigeration cycle, which may | |
| result in a failure or explosion of the product or an injury to your body. | |
|
| |
| 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 | |
Refrigerant | 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 | |
| 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/ | If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or fire is | |
Cabling | caused at user's side. | |
|
| |
| After the work has finished, be sure to use an insulation tester set (500V Megger) to check the | |
| resistance is 1MΩ or more between the charge section and the | |
Insulator | (Earth position). | |
If the resistance value is low, a disaster such as a leak or electric shock is caused at user's side. | ||
check | ||
| ||
| 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 refrigerant and the closed room full with gas is dangerous because a | |
| shortage of oxygen occurs. Be sure to execute ventilation. | |
|
| |
Ventilation | If refrigerant gas has leaked during the installation work, ventilate the room immediately. | |
If the leaked refrigerant gas comes in contact with fire, noxious gas may generate. | ||
|
| |
| 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. |
