WARNING
This unit contains HFC-(R410A), an azeotropic mixture of R-32 (Difluoromethane) and R-125 (Pentafluoroethane). 
DO NOT VENT HFC-(R410A) to the atmosphere. The U.S. Clean Air Act requires the recovery of any residual 
refrigerant. Do not use R-22 service equipment or components on R410A systems.
WARNING!
To avoid possible injury or death due to electrical shock, open the 
power supply disconnect switch and secure it in an open position 
during installation.
CAUTION!
Use only copper conductors for field installed electrical wiring. Unit 
terminals are not designed to accept other types of conductors.
