Verify system compatibility
Equipment designed and approved for R454B
R454B should be selected only when the system labeling and manufacturer documentation specifically authorize its use.
01
Newer air-conditioning systems whose data plate lists R454B
Use only when the equipment manufacturer identifies R454B as an approved refrigerant for the system.
02
Heat pumps designed for compatible A2L refrigerant service
Use only when the equipment manufacturer identifies R454B as an approved refrigerant for the system.
03
Other manufacturer-approved equipment applications that specifically call for R454B
Use only when the equipment manufacturer identifies R454B as an approved refrigerant for the system.
Service discipline
Match the refrigerant, tools and procedure to the equipment.
HVAC and refrigeration systems are built around specific pressure, material, lubricant and safety requirements. Confirm the system requirements before opening or connecting a cylinder.
R454B is classified A2L and requires tools, equipment and procedures suitable for mildly flammable refrigerants.
Do not charge R454B into an R410A system unless the equipment manufacturer specifically approves that conversion.
Follow all applicable ventilation, ignition-control, leak-detection and A2L service requirements.
Cylinder, storage & handling
Keep the product secured, identified and ready for qualified service.
Inspect the delivered cylinder and label before use, and follow the product documentation for handling and storage.
