GENERAL MECHANICAL SPECIFICATIONS

GENERAL - All 2 to 10 ton models ship with a full refrigerant charge. 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 pack- ages/models are designed for suspended mounting via inte- gral 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 protec- tion is provided. External high pressure and low pressure cut- out 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 indepen- dent 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 evap- orator and condenser air movement. blow wheels are fabri- cated of galvanized steel. Blowers employ solid steel shafts, supported in permanently lubricated ball bearing. All blow- ers are belt driven in permanently lubricated ball bearing. All blowers are belt driven. Variable-pitch motor sheaves allow for field adjustment of blower rpm.

ELECTRICAL/CONTROLS - All units are completely factory wired with all necessary controls. Manual reset protection is provided on both evaporator and condenser motors. A man- ual reset circuit is also provided on each compressor control circuit in the event of high/low pressure cutout. A 24 volt con- trol circuit with oversize transformer, is provided for field con- nection.

FILTERS - All models are shipped with 2 inch thick medium- efficiency throwaway filters factory installed. Filter rack is internal to the cabinet.

FACTORY INSTALLED ACCESSORIES

OVERSIZED EVAPORATOR FAN MOTORS - Increased horsepower motors and drive components are available for those applications where external static pressure require- ments exceed the capability of the standard motor.
