This symbol applies to the R32 refrigerant, the type of which is on the label of the outdoor unit. In the case of this refrigerant, the R32 unit uses Warning a flammable refrigerant. (Risk of fire) Yes, if this refrigerant leaks and is exposed to an open flame or a heated part.
- Page 4 • Do not turn on the lights until the entire operation is completed, if the lights are turned on before the entire operation is completed, it may cause serious accidents such as electric shock or fire. • If the leaking air conditioner comes into direct contact with the flame, toxic gases may be produced.
- Page 5 • This unit is part of the package that makes up this air conditioner and cannot be installed in complete sets or with equipment not authorized by the manufacturer. • When a pipe less than 3 meters in length is installed, the sound of the outdoor unit will be transmitted to the indoor unit, which may produce working noise or abnormal noise.
- Page 6 Caution If the unventilated area is smaller than the minimum installation area, the air conditioner should not be installed in this area. The installation height is the minimum installation height, that is, the minimum installation height of the cold air pipe or indoor unit, whichever is the lowest. The following table is determined according to the minimum installation height of 1.8 meters and 2.2 meters If the required minimum installation height is less than 1.8 meters, the minimum installation space must be recalculated.
