OXBOX BY TRANE – WALL MOUNT AIR HANDLER ELECTRIC HEAT KIT, 8 KW, R454B

Model Number: 5JAYHTR1A08BKA (8 kW Electric Heat Kit for OXBOX R‑454B systems)

Purpose: This kit provides electric‐resistance supplemental (or primary) heating inside a wall‐mount indoor air handler cabinet compatible with the OXBOX R‑454B refrigerant line.

Heating Capacity: 8 kW nominal output.

Compatibility: Designed for use with wall‑mount indoor air handlers that are rated for R‑454B refrigerant (mildly flammable A2L class). The corresponding wall‑mount handler series manual indicates field‐installed heaters are available (5kW, 7.5kW, 10kW variants) in the R‑454B wall‑mount line.

Installation: The kit is installed in the indoor handler’s electrical compartment. It must match the air handler’s capacity, wiring, breaker/disconnect sizing, airflow requirements and clearances. Because the system uses R‑454B, proper installation includes leak detection, room‐area limits, ventilation and adherence to safety codes.
