Page 37: 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 38 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.
