This unit contains R-410A high pressure refrigerant. Hazards exist that
could result in personal injury or death. Installation, maintenance, and

designed for R22 refrigerant.

service procedures include the adding or removing of refrigerant, the service
technician must comply with all federal, state and local laws. The procedures
