Please read the se safety pre cauti ons caref ully befo re instal latio n.
Be sure to follow all the preca ution s below, they are all impor tant for ensu ring safe ty.

This symb ol indica tes the possi bilit y of death or serious inj ury.

This symb ol indica tes the possi bilit y of injury or damage to prop erty.

1) This equipment must be grounded (earthed) and installed with ground leakage current breaker. It
may cause electrical shock if grounding isn ot perfect.

2) Do not install the unit in a place near where leakage of flammable gas may occur. If gas leaks and

accumulates near the unit, it may cause fire. Please follow local council’s guidelines and regulations.

3) Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water

may enter the room and damage wall, furniture, floor and carpet.

1) Installation must be strictly in accordance to this installation instructions. If installation is defective, it

will cause water leakage, refrigerant leakage, damage, electrical shock, or fire.

2) Use the included accessories parts and specified parts for installation. Otherwise, it may cause the unit
to fall, water leakage, refrigerant leakage, damage, electrical shock or fire.

3) Install at a strong and firm location which is able to withstand the unit’s weight. If the installation position

is not strong enough orif the installation is not properly done, the set willd rop and cause injury.

4) For electrical work, follow the local national wiring standard, regulation and this installation instructions.
An independent circuit must be used. If electrical circuit capacity is insufficient or if there are defects in

electrical work, it will causeda mage to the unit, electrical shock or fire.

5) Use the specified cable and connect tightly. Clamp the cable so that no external force will be placed

upon the terminal. If connection or fixingi s not perfect, itw illcaus e heat-up or fire at the connection.

6) Wiring routing must be properly arranged so that control board cover is fixed properly. If the control board
cover is not fixed perfectly, it will overheat atthe termina l connection point, causing fire or electrical shock.

7) When carrying out piping connection, ensure that a proper vacuum is achieved and only specified

refrigerant enters the refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high

pressure in the refrigeration cycle, possible explosion and injury.

8) Ensure that the unit is on a dedicated circuit wired to the switchboard with its own isolator and that it is

not on a shared circuit with other electrical appliances. Otherwise, it will cause fire orelect ricalsh ock.
