This product has been designed and manufactured to meet
Energy Star® criteria for energy efficiency when matched
with appropriate coil components. However, proper
refrigerant charge and proper air flow are critical to achieve
rated capacity and efficiency. Installation of this product
should follow all manufacturing refrigerant charging and air
flow instructions. Failure to confirm proper charge and
air flow may reduce energy efficiency and shorten
equipment life.
