The QMARK CDF548 is a ceiling-mounted electric heater rated at 4 kilowatts and designed to operate on a 208-volt supply. It delivers forced-air heat from an overhead position, distributing warmth across the floor-level occupied zone below. Ceiling mounting keeps the unit out of the way of walls, doors, and equipment, making it a practical choice for spaces where wall or baseboard installation is not feasible. A licensed electrician or qualified HVAC technician handles the installation. At 27 pounds, the unit requires secure structural support at the ceiling mount point.
The CDF548 is suited for commercial and light industrial applications where overhead electric heat is the preferred solution. Typical install locations include garages, workshops, warehouses, utility rooms, entryways, and similar spaces that require reliable supplemental or primary electric heat without occupying wall or floor space. The 208-volt single-phase supply matches common commercial panel configurations.
Designed as an OEM-style ceiling heater for commercial and light industrial electric heating applications requiring a 208-volt, 4 kW overhead unit.
Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out power at the panel before any wiring or mounting work. Confirm that the ceiling structure can support the unit weight before fastening the mounting hardware. Do not energize the unit until all wiring connections are complete and the enclosure is fully secured.
