The DSG1023DH00001S uses a 208/230-volt, three-phase, 60 Hz electrical supply and measures 93 3/4 inches wide by 60 3/8 inches deep by 54 5/8 inches high, with an overall height of 82.6 inches. The unit has an operating weight of 1,118 pounds and a shipping weight of 1,190 pounds.
Controls & Comfort
The DSG1023DH00001S uses a 24-volt electromechanical controls package and two individually circuited scroll compressors to provide staged cooling operation. The direct-drive indoor fan operates across a 300–1,600 RPM range and provides a nominal 3,230 CFM of airflow. Convertible airflow orientation provides flexibility for downflow or horizontal applications.
Commercial Applications
The Daikin DSG1023DH00001S is designed for larger light commercial rooftop applications where dependable gas heating and electric cooling are required from a single packaged system.
