Tempstar® brand PDX3 dual-fuel package units have efficiency ratings of 13 SEER, up to 80 percent AFUE, and 7.7 HSPF. They use R-410A refrigerant. The heat pump features a new defrost system that helps keep coils ice-free for more efficient, reliable operation. According to the manufacturer, the high-efficiency blower motors control airflow and reduce sound better than conventional PSC motors to help them achieve even quieter operation than before. A new Air Management System, common to all Tempstar package products, ensures smooth, quiet airflow through the condenser, while improving the overall strength of the unit. These package units are designed for ground or rooftop applications. They are shipped for horizontal application and can be converted to downshot. Features include an enhanced Copeland scroll compressor, condenser coils with sturdy wire inlet grilles, and UV-rated vinyl mesh installed on the surface of the coils.
