Resumen del manual
Both models present a low profile and do not distract from the architecture of the building. MODEL 585E is designed for horizontal side-by-side duct connections and can be installed at ground level or on a roof. The 585E is ideal for the replacement market. MODEL 579D has the supply- and return-air openings on the bottom of the unit. The 579D is designed for rooftop installation and mounts on a factory-supplied, roof-mounting curb. The ductwork connects to the curb so that the air ducts and curb can be installed before unit arrival. FEATURES FACTORY-ASSEMBLED PACKAGE is a compact, fully self-contained, combination gas heating/electric cooling unit that is prewired, prepiped, and precharged for minimum installation time and expense. TWO RUGGED, HIGH-EFFICIENCY COMPRESSORS provide two-stage cooling to conserve energy by shutting down one compressor during light cooling loads. These compressors are electrically and mechanically independent; therefore, cooling is still available even if one stage fails. LOW-PRESSURE PROTECTION is standard. TWO-STAGE HEATING AND TWO-STAGE COOLING reduces equipment cycling and gives better control of the conditioned space temperature and humidity. INTERMITTENT SPARK IGNITION that lights pilot only on a “call for heat” by the indoor thermostat. An LP (propane) conversion kit is available for both models. HIGH-EFFICIENCY, FOUR-PASS HEAT EXCHANGER-The four-pass tubular heat exchanger design provides maximum heat transfer to the heated area. POSITIVE-PRESSURE COMBUSTION AND MECHANICAL FLUE GAS VENTING are unaffected by adverse wind conditions. CRANKCASE HEATERS AND FILTERrDRIERS are standard on both models. WEATHERIZED CABINETS are constructed of heavy-duty, phosphated, zinc-coated steel and finished with corrosion-resistant, modified alkyd, fade-resistant, baked Malibu Beige enamel. Interior surfaces of the evaporator/heat exchanger compartment are insulated to help keep the conditioned air from being affected by the outdoor ambient temperature. VERTICAL CONDENSER AIR DISCHARGE prevents recirculation of hot condenser air and reduces operating noise level. COMPRESSOR ISOLATION MOUNTING eliminates vibration (noise) transmission to building structure. CORROSION-RESISTANT HEAT EXCHANGERS AND BURNERS for longer life. FURNACE SAFETY CONTROLS shut off gas in event of pilot outage, combustion-air failure, overheating of heat exchangers, or flame rollout. PROTECTION AS REQUIRED BY N.E.C. for fan motors. COMPROTEC®—standard on both models, prevents compressor rapid-cycling.
