Installation
WARNING
• Install the air conditioner securely in a location where the base can sustain the weight adequately. If the strength is not
enough, the unit may fall down resulting in injury.
• Carry out the specified installation work to guard against the possibility of high winds and earthquake. If the air
conditioner is not installed appropriately, a unit may topple over or fall down, causing an accident.
• If the unit is installed in a small room, observe applied floor area for the unit and take appropriate measures to prevent
the refrigerant from exceeding the limit concentration even if it leaks. Consult dealer where you purchased the product
to install the unit in a small room. Accumulation of highly concentrated refrigerant may cause a fire or oxygen deficiency
accident.
• For simultaneous twin, triple, or double twin system, indoor unit must be installed in the same room. If an indoor unit
is installed in the small room, an applied floor area for the unit may not be observed.
CAUTION
Strictly comply with the following rules to prevent damage of the indoor units and human injury.
• Do not put a heavy article on the indoor unit or let a person get on it. (Even units are packaged)
• Carry in the indoor unit as it is packaged if possible. If carrying in the indoor unit unpacked by necessity, use buffering
cloth or other material not to damage the unit.
• Carry the package by four or more persons, and do not bundle it with plastic band at positions other than specified.
• Be sure to take measures to prevent falling at the wall surface and the floor and fix it surely considering prevention
of accident of falling because this unit is formed into a thin type. If it is not fixed, a falling accident may occur.
