Carrier doesn’t ensure the same performances when the unit operates at 60Hz; the RPM and power input of the fan-motor are usually higher. Dimensional drawings NOTE: All drawings shown have the coil connections on the right-hand side. Units with left-hand connections are symmetrical. AIR TREATMENT Standard unit with free air inl
