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 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 condenser air movement. blow wheels are fabricated of galvanized steel. Blowers employ solid steel shafts, supported in permanently lubricated ball bearing. All blowers 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 manual reset circuit is also provided on each compressor control circuit in the event of high/low pressure cutout. A 24 volt control circuit with oversize transformer, is provided for field connection.
FILTERS - All models are shipped with 2 inch thick mediumefficiency 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 requirements exceed the capability of the standard motor.

CORROSION RESISTANT COATINGS - Condenser and/or evaporator coils shall have a 2 to 3 mil coating of Heresite P- 413 protective coating applied in a multiple dip and bake process.
STAINLESS STEEL DRAIN PAN - Evaporator drain pan shall be fabricated of 304 stainless steel material. The 3/4 in. NPT drain connection fitting is also of 304 stainless steel.
HOT GAS BYPASS - Adjustable hot gas regulator and all necessary piping shall be installed on lead compressor circuit. Bypass capacity shall be minimum 50% of compressor capacity. The bypass valve opens at a preset suction pressure to prevent coil freeze-up at light evaporator load, or low

airflow conditions. The use of the field installed Low Ambient Control is strongly recommended when hot gas bypass is installed.
FIELD INSTALLED ACCESSORIES
LOW AMBIENT CONTROL - Head pressure control damper kit will allow unit operation down to 0°F ambient. Damper assembly fits over condenser air intake. The kit includes damper actuator, and low pressure switch bypass timer(s).
