Page 77: Selection Of Installation Place
SELECTION OF INSTALLATION PLACE • Install the air conditioner at enough strong place to withstand the weight of the unit. If the strength is not enough, the unit may fall down resulting in injury. • Install the air conditioner at a height 2.5m or more from the floor. If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous because you may contact with revolving fan or active electricity. - Page 78 SELECTION OF INSTALLATION PLACE Selection of installation place In case of continued operation of the indoor unit under high-humidity conditions as described below, dew may condense and water may drop. Especially, high-humidity atmosphere (dew point temperature : 23°C or more) may generate dew inside the ceiling.

Page 79: External View
External view 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. (Even units are packaged) • Carry in the indoor unit as it is packaged if possible. If carrying in the indoor unit unpacked by necessity, be sure to use buffering cloth, etc. - Page 80 SELECTION OF INSTALLATION PLACE Opening a ceiling and installation of hanging bolts <Treatment of ceiling> The ceiling differs according to structure of building. For details, consult your constructor or interior finish contractor. In the process after the ceiling board has been removed, it is important to reinforce ceiling foundation (frame) and to keep horizontal level of installed ceiling correctly in order to prevent vibration of ceiling board.

Page 95: Selection Of Installation Place
SELECTION OF INSTALLATION PLACE • Install the air conditioner at enough strong place to withstand the weight of the unit. If the strength is not enough, the unit may fall down resulting in injury. • Install the air conditioner at a height 2.5m or more from the floor. If you insert your hands or others directly into the unit while the air conditioner operates, it is dangerous because you may contact with revolving fan or active electricity. -
