Features of the enhanced S-Classâ„¢ rooftop unit include 35-, 45-, and 50-ton capacities; gas/electric or cooling-only models; and efficiency levels up to 10.5 SEER and 12.6 IPLV. The company says the optional spring isolation reduces noise by isolating components, using 2-inch vibration isolation springs; this option is available on supply fans, high static power exhaust fans, and compressors. The optional powered ground fault circuit interrupter (115-volt factory wired service outlet) supplies power directly from the unit to hand tools. Other options include horizontal discharge, a phase monitor, and export packaging. These options help improve unit performance, installation, and serviceability, while better controlling the indoor environment, the company says.
