8.0 DUAL DRIVE COMPRESSORS The -039, -048, & -060 condensing units contain two compressors to deliver maximum efficiency and comfort. The Dual Drive Compressors are sized to increase run times at first stage operation (partial capacity). When additional capacity is needed, a two stage thermostat - Rheem RASL-JEC | Installation Instructions - Page 17
