· Installation should be performed by a

electrical shock or fire.)

·Install the unit according to the instructions given in this manual. (Incomplete installation may cause water

leakage, electrical shock or fire).

·Be sure to use the supplied or specified installation parts. (Use of other parts may cause the unit to get

loosened, water leakage, electrical shock or fire).

·Install the air conditioner on a solid base that can support the unit weight. (An inadequate base or incomplete

installation may cause injury if the unit falls off the base).

·Electrical work should be carried out in accordance with the installation manual and the local national electrical

wiring rules or code of practice.

(Insufficient capacity or incomplete electrical work may cause electrical shock or fire).

· Be sure to use a dedicated power circuit. (Never use a power supply shared by another appliance).

· For wiring, use a cable long enough to cover the entire distance. Do not use an extension cord.

·Do not put other loads on the power supply, use a dedicated power circuit.

·Use the specified types of wires for electrical connections between the indoor and outdoor units. (Firmly clamp

the interconnecting wires so their terminals receive no external stresses).

·Incomplete connections or clamping may cause terminal overheating or fire.

·After connecting

covers or panels. (Install covers over the wires, incomplete cover installation may cause terminal overheating,

electrical shock or fire).

·When installing or relocating the system, be sure to keep the refrigerant circuit free from air (Air in the

refrigerant circuit may causes an abnormal pressure rise or rupture, resulting in injury).

·If any refrigerant has leaked out during the installation work, ventilate the room.

·After all installation is completed, check to make sure that no refrigerant is leaking out. (The refrigerant

produces a toxic gas if exposed to flames).

·When carrying out piping connection, take care not to let air substances other than the specified refrigerant

·Do not install the air conditioner in a place where there is danger of exposure to inflammable gas leakage. (If

the gas leaks and builds up around the unit, it may catch fire).

· Establish drain piping according to the instructions in this manual. (Inadequate piping may cause flooding).
