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