Anleitung Zusammenfassung
The air ducts connect to the curb only, therefore, the curb and ductwork may be installed before the unit arrives at the jobsite A 24-inch high, factory-supplied curb for side supply/return duct connections to an over-and-under duct configuration is also available for grade level or rooftop installation SYSTEM FEATURES FULL PERIMETER CURB MOUNTING ON PREFABRICATED ROOF CURB. The curb, which is easily field-assembled, can be installed at the jobsite before the unit is installed This eliminates a major leak source. An optional side supply/return roof curb for grade level installation is possible without costly modifications to the unit base ECONOMIZER OPERATION uses an enthalpy control to select suitable air quality for “free” cooling operation by measuring the dry bulb/humidity mix BAROMETRIC RELIEF-AIR PACKAGE exhausts stale indoor air during the economizer operation TWO-POSITION DAMPER PACKAGE includes a spring-return motor that closes off the outdoor air during unit shutdown LOW-AMBIENT operation for outdoor-air temperatures down to 35°F is standard A 0°F low-ambient kit is available as optional equipment UNIT FEATURES FACTORY-ASSEMBLED PACKAGE is a compact, fully self-contained cooling unit that is prewired, prepiped, and precharged for minimum installation time and expense TWO HIGH-EFFICIENCY, HERMETIC COMPRESSORS on sizes 120 & 150 provide 2-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. A RUGGED, SERVICEABLE, SEMIHERMETIC COMPRESSOR with 33% capacity reduction is used on size 180. Part-load operation provides better humidity and temperature control of conditioned space MANUAL OUTDOOR-AIR DAMPER, which is standard equipment, provides up to 25% outdoor air for ventilation INTERNAL AND EXTERNAL PROTECTION against compressor overload and overheat conditions. HIGH- AND LOW-PRESSURE PROTECTION against abnormal operating conditions in the refrigerant cycle VERTICAL CONDENSER-AIR DISCHARGE prevents recirculation of hot condenser air and reduces the operating noise level PROTECTION AS REQUIRED BY N.E.C. for fan motors THERMAL- AND ACCOUSTIC-INSULATED air handling section COMPRESSOR ISOLATION MOUNTING eliminates vibration (noise) transmission to the building structure. CRANKCASE HEATERS AND FILTER-DRIERS are standard on both models ADJUSTABLE BELT-DRIVE BLOWER AND OPTIONAL DRIVES meet most air delivery requirements TWO-INCH FILTERS are standard. ELECTRIC HEATERS are available as optional equipment for operation on 208, 230, or 460 volts. SINGLE-POINT POWER CONNECTION to units with field-installed electric heaters Only one power supply with one disconnect switch is required WEATHERIZED CABINET of heavy-duty phosphated and zinc-coated steel Baked-on modified alkyd enamel finish is corrosion resistant and fade resistant. Interior surface of the evaporator compartment is insulated to help isolate the conditioned air from the outdoor ambient temperature.
