The International Comfort Products 1203868 is an A2L mitigation harness designed to support safe refrigerant management in systems using A2L-class low-global-warming-potential refrigerants such as R-32 and R-454B. This wiring harness integrates into the refrigeration circuit to meet mitigation requirements that address the mild flammability characteristics of A2L refrigerants. It is installed by licensed HVAC technicians during new equipment installation or system retrofits that require updated safety compliance components.
The 1203868 is applicable to residential and light-commercial HVAC systems that use A2L refrigerants and require mitigation harness assemblies as part of their design or regulatory compliance. This harness is used when equipment configurations must satisfy ventilation, leak detection, or wiring-based mitigation standards associated with A2L refrigerant use. Consult the equipment installation manual to confirm correct harness routing and connection requirements for the target system.
Designed as an OEM-style A2L mitigation harness for International Comfort Products HVAC equipment that operates with A2L-class refrigerants. Consult the applicable equipment documentation to verify compatibility before installation.
Installation should be performed by a licensed HVAC technician familiar with A2L refrigerant handling requirements and applicable local codes. Disconnect all electrical power to the unit before accessing internal wiring or connecting the harness. Follow the equipment manufacturer's wiring diagram precisely; do not modify the harness or substitute connectors. Ensure all A2L mitigation requirements per the equipment installation manual and applicable mechanical codes are satisfied before returning the system to operation.
