1 Safety Precautions
This mark indicates procedures which, if improperly performed, might lead to
the death or serious injury of the user.
This mark indicates procedures which, if improperly performed, might
possibly result in personal harm to the user, or damage to property.
(1). Installation should be left to the dealer or another professional. Improper installation may
cause water leakage, electrical shock, or fire.
(2). Install the air conditioner according to the instructions given in this manual. Incomplete
installation may cause water leakage, electrical shock, or fire.
(3). Be sure to use the supplied or specified installation parts. Use of other parts may cause the
unit to come to lose, water leakage, electrical shock, or fire.
(4). Install the air conditioner on a solid base that can support the weight of the unit. An inadequate
base or incomplete installation may cause injury in the event the unit falls off the base.
(5). Electrical work should be carried out in accordance with the installation manual and the
national electrical wiring rules or code of practice. Insufficient capacity or incomplete
electrical work may cause electrical shock or fire.
(6). Be sure to use a dedicated power circuit. Never use a power supply shared by another
appliance.
(7). For wiring, use a cable length enough to cover the entire distance with no connection. Do not
use an extension cord. Do not put other loads on the power supply, use a dedicated power
circuit. (Failure to do so may cause abnormal heat, electric shock or fire.)
(8). 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.
(9). After connecting interconnecting and supply wiring be sure to shape the cables so that they do
not put undue force on the electrical covers or panels. Install covers over the wires.
Incomplete cover installation may cause terminal overheating, electrical shock, or fire.
(10). If any refrigerant has leaked out during the installation work, ventilate the room. (The
refrigerant produces a toxic gas if exposed to flames.)
(11). After all installation is complete, check to make sure that no refrigerant is leaking out. (The
refrigerant produces a toxic gas if exposed to flames.)
