This pr oduct has been designed and manufactured to

meet ENERGY STAR criteria for energy efficiency when

mat che d with approp riat e coil comp on e n ts. How e ve r,

proper refrigerant charge and proper air flow are critical

to achieve rated capacity and efficiency . Installation of

this product should follow the manufacturer’s refrigerant

char g in g and air flow instruct io n s. Failur e to confirm

proper charge and airflow may reduce energy efficiency

and shorten equipment life.
