The SH10B heat pump has a 10-SEER cooling efficiency, 2- to 5-ton cooling capacity, and up to 7 HSPF. The 4- and 5-ton models are convertible to the downshot position for rooftop applications. The company says that the scroll compressor has internal pressure relief valves, inherent thermal protection, and a factory-installed low-pressure switch. Features include an insulated cabinet, vertical air discharge, permanently lubricated motor, galvanized steel rails, an evaporator coil with an antimicrobial coating, and adjustable time/temperature defrost controls. The optional field-installed electric auxiliary heat allows custom heat selection for individual applications and preserves flexibility for heat pump-only applications in warmer climates, states the company.
