Oxbox 5JAYHTR1A20BK Heat Kit 20 Kw R-454B Air Handlers

Product Description

The Oxbox 5JAYHTR1A20BK is a 20 kW electric heat kit designed for installation in compatible air handler systems. This auxiliary heating accessory supplements primary cooling or heat pump operation by providing resistance heat through the air handler cabinet. It is sized for residential or light commercial applications where supplemental or emergency heat capacity is required. HVAC technicians install this kit as part of a complete system build-out or as a field-installed accessory on qualifying air handlers. The 20 kW output provides substantial heating capacity for larger conditioned spaces.

This heat kit is intended for use with R-454B refrigerant-based air handlers in the Oxbox 5JAYHTR1A series. Typical installations include new construction and retrofit applications where electric supplemental heat is specified. The kit integrates within the air handler cabinet and works in conjunction with the system control board to stage or sequence heat as demand requires. Installations in regions with moderate climates commonly use electric heat strips as a cost-effective backup to heat pump operation.

Installation Notes

Installation must be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the air handler before beginning installation. Electric heat kits operate at line voltage and require proper overcurrent protection sized to the kit load per NEC requirements. Verify that the air handler control board and wiring are rated to support the selected heat kit capacity before completing installation.
