    9-2. Selection of Installation Place WARNINGS • Install the air conditioner where there is sufficient strength to withstand the weight of the unit. If the strength is not sufficient, the unit may fall down resulting in injury. • Install the air conditioner at a position keeping the height by 2.5m or more from the floor. If you insert your hands or others directly into the unit during running of the air conditioner, it is dangerous because you may contact with revolving fan or active electricity.
