The 12 and 15 ton models are shipped as separate evaporator and condensing unit modules (nitrogen holding charge only). The 4 through 10 ton units include refrigeration line shut-off valves to allow the units to be field split. All packages/models are designed for suspended mounting via integral structural channels. CABINET - All cabinets are completely constructed of 18 Gauge corrosion resistant "Galvalume" coated steel. The entire unit interior (both evaporator and condensing section) is insulated with 1/2" thick 2 LB density insulation. Service panels are equipped with 1/2" thick 2 lb. density insulation. Service panels are equipped with lifting handles for ease of removal and handling. COMPRESSORS - All models utilize "Scroll" type hermetic compressors. Compressors are mounted on rubber isolators to minimize vibration transmission. Internal overload protection is provided. External high pressure and low pressure cutout switches are included in each compressor control circuit. Crankcase heaters are standard on all models. REFRIGERANT CIRCUIT - The 2 to 5 tons units use a single refrigeration circuit. The 8 to 15 ton units feature two independent refrigeration circuits. Each circuit includes an adjustable thermal expansion valve (with external equalizer), liquid line filter drier, sight glass/moisture indicator, and service gauge ports. EVAPORATOR AND CONDENSER COILS - The evaporator and condenser coils are constructed of internally enhanced copper tubes mechanically bonded to rippled aluminum plate fins. Both coils are employed in a draw-through configuration. Large evaporator coil face area minimizes potential water blow-off (max face velocity is 550 fpm at rated airflow). INDOOR/OUTDOOR FANS - Forward curved, double inlet and double width centrifugal blowers are used for both evaporator and cond...
