If installation is defective, it will cause water leakage, electrical shock fire.
(3) When installing the unit in a small room, take measures against to keep refrigerant concentration
from exceeding allowable safety limits in the event of refrigerant leakage.
Contact the place of purchase for more information. Excessive refrigerant in a closed ambient can lead
to oxygen deficiency.
(4) Use the attached accessories parts and specified parts for installation. otherwise, it will cause the set
to fall, water leakage, electrical shock fire.
(5) 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 to cause injury.
(6) The appliance must be installed 8.2ft(2.5m) above floor.

fluid flow.
(11) For electrical work, follow the local national wiring standard, regulation and installation instruction.
An independent circuit and single outlet must be used.
If electrical circuit capacity is not enough or defect in electrical work, it will cause electrical shock fire.
(12) 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.
(13) 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

Otherwise, it will cause lower capacity, abnormal high pressure in the refrigeration cycle, explosion and
injury.
(17) 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.
(18) Carry out the specified installation work after taking into account strong winds, typhoons or
