WARNING!
This mark indicates procedures which, if improperly performed, might lead to
the death or serious injury of the user.
CAUTION!
This mark indicates procedures which, if improperly performed, might possibly
result in personal harm to the user, or damage to property.
WARNING !
Installation should be left to the dealer or another professional. Improper installation may cause water
leakage, electrical shock, or fire.
Install the air conditioner 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
come to lose, water leakage, electrical shock, or fire.
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.
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.
Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.
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.)
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 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.
If any refrigerant has leaked out during the installation work, ventilate the room. (The refrigerant
produces a toxic gas if exposed to flames.)
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.)
