Description

Model (example listing): “OXBOX R‑454B 8KW Electric Heat Kit for Package Unit” (part number: 917‑5JAYHTR1P08BKA) according to a retailer.
Purpose: This kit is designed to provide 8 kW of electric resistance heating to a package unit (i.e., self‑contained HVAC unit) that uses the refrigerant R‑454B (a “mildly flammable” A2L refrigerant).
Use case: It serves as a supplemental (or potentially primary) heating source integrated into a package HVAC system to cover heating when the main heat‑pump component may not suffice or as added heat capacity.
Compatibility: The kit must be used with a package unit that supports R‑454B refrigerant and is configured appropriately for that refrigerant and heating accessory.
Installation: The kit is field‑installed in the package unit’s heating section. It requires correct wiring, breaker/disconnect sizing, adequate airflow (if applicable) and must comply with safety/clearance requirements especially because the system uses R‑454B. The manufacturer stresses that units designed for R‑454B must be installed in compliance with special codes and have specific sensors for flammable refrigerant.
