Frigidaire's FFTA1233Q2 12,000 BTU 230V Through-the-Wall Air Conditioner is perfect for cooling a room up to 550 square feet. This unit is designed for through-the-wall installation and is not designed for standard window installation. It will fit most existing wall sleeves and includes a standard universal interior trim kit. New wall sleeves are sold separately. This unit also requires a special 230V electrical outlet and will not operate with a standard 115V household electrical outlet. The ready-select electronic controls allow you to set the comfort level to your preference, while a convenient temperature-readout displays the set temperature. Effortless temperature sensing remote control allows you to see, set and maintain room temperature from across the room. The multi-speed fan features three different speeds for more cooling flexibility and the 4-way comfort control design allows you to easily control the direction of the cool air, wherever the unit is mounted.
