Use of the AHRI Certified TM Mark
indicates a manufacturer's participation in
the program. For verification of certification
for individual products, go to
www.ahridirectory.org .
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 the manufacturer's refrigerant charging and air flow
instructions. Failure to confirm proper charge and airflow may
reduce energy efficiency and shorten equipment life.
