IMPORTANT: Do not release refrigerant to the atmosphere! If required service
procedures include the adding or removing of refrigerant, the service technician
must comply with all federal, state, and local laws. Service procedures should only
be performed by a qualied HVAC technician.
Form P-Y (6-16), PN 273651R23, Page 1
DANGER
This unit contains R-410A high pressure refrigerant. Hazards exist that could result
in personal injury or death. Installation, maintenance, and service should only be
performed by an HVAC technician qualied in R-410A refrigerant and using proper
tools and equipment. Due to much higher pressure of R-410A refrigerant, DO NOT
USE service equipment or tools designed for R22 refrigerant.
