Important Safety & Compliance Information

WARNING — A2L REFRIGERANT: R-454B is classified as A2L (lower flammability and lower toxicity). Appropriate ventilation, ignition-source control, leak detection, PPE, and A2L-compatible service equipment are required when handling this refrigerant.

Use Only in Compatible Equipment: R-454B should be used only in HVAC systems specifically designed, certified, and approved for R-454B. Do not substitute or introduce R-454B into equipment designed for another refrigerant unless expressly authorized by the equipment manufacturer and applicable regulations.

Professional Use Only: Installation, charging, recovery, leak testing, and servicing should be performed by appropriately trained and qualified HVAC/R technicians in accordance with manufacturer instructions and applicable safety requirements.

Regulatory Compliance: Requirements for A2L refrigerants may include technician training or certification, specialized service equipment, storage and transportation requirements, labeling, sales restrictions, and other regulatory provisions. Verify all applicable local, state, federal, and national requirements before purchasing, handling, or using the product.
