|
|
CAUTION |
This symbol indicates the possibility of injury or damage to property. |
|
|
The items to be followed are classified by the symbols:
Symbol with background white denotes item that is PROHIBITED from doing.
WARNING
1)Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock fire.
2)Install according to this installation instructions strictly. If installation is defective, it will cause water leakage, electrical shock fire.
3)Use the attached accessories parts and specified parts for installation. otherwise, it will cause the set to fall, water leakage, electrical shock fire.
4)Install at a strong and firm location which is able to withstand the set,s weight. If the strength is not enough or installation is not properly done, the set will drop and cause injury.
5)For electrical work, follow the local national wiring standard, regulation and this installation instructions. An independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defect found in electrical work, it will cause electrical shock fire.
6)Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.
7)Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock.
8)When carrying out piping connection, take care not to let air substances other than the specified
refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and injury.
9)Do not modify the length of the power supply cord or use of extension cord, and do not share the single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.
CAUTION
1)This equipment must be earthed and installed with earth leakage current breaker. It may cause electrical shock if grounding is not perfect.
2)Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding of the unit, it may cause fire.
