3. Use the attached accessories parts and specified parts for installation. 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 this 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 (1.5 mm

) 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 at connection point of terminal, fire or electrical shock.
8. When carrying out piping connection, take care not to let air or other substances other than the specified refrigerant go
into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure in the refrigerant cycle,
explosion and injury.
9. When connecting the piping, do not allow air or any substances other than the specified refrigerant (R410A) 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.
