OXBOX BY TRANE – ELECTRIC HEAT KIT, PACKAGE UNIT, 8 KW, R454B

The kit is listed under part number 917‑5JAYHTR1P08BKA for the “8 KW Electric Heat Kit for Package Unit” for the OXBOX R‑454B line.

It provides 8 kW of electric resistance heating designed to integrate with a package HVAC unit that uses refrigerant R‑454B (an A2L, mildly‑flammable refrigerant).

Usage: This accessory is for upgrading or supplementing the heating capacity of a package unit (rather than just the indoor blower/coil only).

Compatibility: It must be used with a package unit rated for R‑454B, and the rest of the system (indoor/outdoor, refrigerant lines, controls) must be designed for that refrigerant and electric kit.

Installation: Field‑installed in the package unit’s heater section (or where specified), and installation must follow proper wiring, breaker sizing, airflow and refrigerant safety procedures specific to R‑454B. The official manual for the R‑454B wall‑mount air handlers notes field‑installed electric heater kits.
