Installation
111
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.
(7) The appliance shall not be installed in the laundry.
(8) Before obtaining access to terminals, all supply circuits must be disconnected.
(9) The appliance must be positioned so that the plug is accessible.
(10) The enclosure of the appliance shall be marked by word, or by symbols, with the direction of the
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
electrical shock.
(14) If the supply cord is damaged, it must be replaced by the manufacture or its service agent or
similarly qualified person in order to avoid a hazard.
(15) An all-pole disconnection switch having a contract separation of at least 3mm in poles should be
connected in fixed wiring.
(16) When carrying out piping connection, take care not to let air substances go into refrigeration cycle.
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
earthquakes.
Improper installation work may result in the equipment falling and causing accidents.
Remark: Failure to observe a warning may result in death.
1.3.8 Caution
(1) Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, lightning rod or a telephone ground wire.
Incomplete grounding may result in electric shocks.
(2) Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks.
(3) Connect the outdoor unit wires, and then connect the indoor unit wires.
You are not allowed to connect the air conditioner with the power source until wiring and piping the air
