The Payne PH10 is a discontinued split-system heat pump with an efficiency rating of 10.0 SEER and 6.8 HSPF. It featured a copper tube aluminum fin coil designed for greater heat transfer, while an enclosed PSC fan motor provided greater reliability in all weather. The compressor was protected by an accumulator and a low-pressure switch which stopped the compressor if the refrigerant charge was lost. The steel cabinet was protected by a baked-on powder paint coating.
