The switchable wattage setting allows a single unit to serve different room-load requirements without stocking multiple heaters. Designed for commercial and light industrial applications, this unit delivers consistent convective or forced-air heat in environments where 277-volt single-phase power is available. Licensed electricians are the primary installers for this class of equipment. At 27 pounds, the CDF547 is a substantial unit suited for permanent wall-mount installation.\u003c\/p\u003e\n\u003cp\u003eThe CDF547 is well suited for commercial spaces, warehouses, utility rooms, and similar areas supplied by 277-volt branch circuits, which are common in commercial electrical distribution systems. The multi-wattage design gives the installing electrician flexibility during commissioning to match heater output to the actual heat-loss calculation for the space. It is not intended for standard 120-volt or 240-volt residential branch circuits without confirmed voltage compatibility.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSelectable output: 4 kW, 3 kW, or 2 kW from a single unit\u003c\/li\u003e\n  \u003cli\u003eRated for 277-volt single-phase commercial power\u003c\/li\u003e\n  \u003cli\u003ePermanent wall-mount construction at 27 pounds\u003c\/li\u003e\n  \u003cli\u003eReduces stocking complexity with multi-wattage switching\u003c\/li\u003e\n  \u003cli\u003eSuited for commercial and light industrial heating applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct installation unit for commercial wall heater applications requiring 277-volt electric resistance heating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Shut off and lock out the branch circuit breaker before any wiring or mounting work. Verify the supply voltage matches the 277-volt rating before energizing the unit.
