The maximum area that can be cooled by this air conditioner depends on several factors. High outdoor temperatures, many and/or large windows, flat roofs, a high number of people in the room, and numerous electrical devices in the space all affect the cooling performance. If these factors are present to a lesser extent (low heat loads), the air conditioner can cool a larger area; if they are present to a greater extent (high heat loads), only a smaller area can be cooled. The unit is filled with propane R 290. Be sure to follow the manufacturer's usage and repair guidelines. Carefully read the manual before use and pay attention to all safety warnings and instructions. Failure to heed safety notices and instructions may result in injury or property damage.
