1. Engage dealer or specialist for installation. If installation 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. 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, unit will drop and cause injury.
5. For electrical work, please 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 and connect tightly for indoor-outdoor connection. Please clamp the cable firmly 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. The outlet cable shall be
fastened by the two clamps of the indoor unit.
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, please 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 refrigeration 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. (only for models: CS/CU-V7CK, V9CK, V12CK, W7CK, W9CK, W12CK)
