The FIRST COMPANY 9-310-3722 is a 5 kW electric heater module designed for use in air handler and fan coil systems. It provides supplemental or primary electric heat within the air stream, converting electrical energy into usable heat output distributed through the duct system. At 26 inches wide, it is sized for compatibility with matching air handler cabinets. Installation is typically performed by a licensed HVAC technician as part of a complete heating system setup or a heater module replacement service.
This heater module is suited for residential and light commercial air handler applications where electric heat is the selected heat source. It fits into modular air handler configurations where heater sections are field-installed or replaced as a discrete component. The 26-inch width dimension is a key sizing reference when matching the module to an existing air handler cabinet or replacement application.
Designed as an OEM-style replacement heater module for compatible FIRST COMPANY air handler and fan coil systems requiring a 5 kW electric heat section.
Electric heater modules must be installed by a qualified HVAC technician in accordance with NEC requirements for electric heating equipment. Always disconnect and lock out power to the air handler before removing or installing any heater module. Verify that the electrical supply voltage, amperage capacity, and breaker sizing meet the requirements for a 5 kW load before energizing the system. Do not operate the heater module without adequate airflow across the element.
