Overview of the 4SHP20LX
The Armstrong Air 4SHP20LX is a variable capacity heat pump with an efficiency rating of up to 20 SEER and 10 HSPF. An inverter-driven scroll compressor which changes speeds in precise increments for optimal efficiency is protected by high- and low-pressure switches which prevent the compressor from turning on if refrigerant levels are too high or too low. A swept wing fan design, discharge muffler and heavy duty compressor sound blanket help keep sound levels as low as 65 decibels. A communicating control board continuously monitors the system, while 45-degree offset gauge ports, easily accessible service valves and removable panels provide easy serviceability. A durable galvanized steel louvered panel cabinet with a baked polyester paint finish protects the unit from corrosion and weather hazards.
