However, proper refrigerant charge and proper air flow are critical to achieve ratedcapacity and efficiency. Installation of this product should follow the manufacturer's refrigerant charging and air flowinstructions. Failure to confirm proper charge and airflow may reduce energy efficiency and shorten equipment life.
