1. Engage dealer or specialist for installation and servicing. If installation or servicing done by the user is defective, it will cause water
leakage, electrical shock or fire.
2. Install according to this installation instruction strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
3. Use the attached accessories parts and specified parts for installation and servicing. Otherwise, it will cause the set to fall, water
leakage, fire or electrical shock.
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 the installation instruction. 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 or
fire.
6. Use the specified cable and connect tightly for indoor/outdoor connection. 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. Wire 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 or fire at the connection point of terminal, fire or electrical shock.
8. When connecting the piping, do not allow air or any substances other than the specified refrigerant to enter the refrigeration cycle.
Otherwise, this may lower the capacity, cause abnormally high pressure in the refrigeration cycle, and possibly result in explosion and
injury.
