3 DESCRIPTION These units are completely assembled, piped, wired, charged and tested at the factory and are shipped ready for immediate installation. Only the power supply wiring, the thermostat wiring, the condenser water piping, the condensate drain piping and the ductwork are required to complete the installation. Units include a one-year limited warranty on all replacement parts and a five-year limited warranty on each compressor. APPLICATION FLEXIBILITY These ìcooling onlyî units can be applied with: 1. Cooling towers. 2. Well or surface water providing the temperature and the GPM of the water meet the application limitations of the unit. 3. Brackish or salt water and a secondary heat exchanger. They can be installed: 1. Within the conditioned space as ìfree standingî units without any ductwork. Supply air plenum and return air grille accessories are available for these freestanding applications. 2. In an equipment room with both supply and return air ductwork GENERAL Horizontal (CH) units are designed for suspended mounting. HWC models are shipped with ëstraight-throughí evaporator fan discharge as standard. Airflow orientation is field convertible to side discharge. Vertical (CU) units are designed for free-standing floor mounting. All units are completely factory wired and pre-piped. Water supply, water outlet, and condensate drain connections are via female pipe thread fittings. All models 5-25 tons ship as factory-charged unitized packages. The 5-15 ton units may be field split between the evaporator /compressor section and the upper blower section; installation is possible through standard height doorways and elevators. All packages are designed for free-standing floor mounting. All models are shipped with vertical evaporator fan discharge as standard. Units are completely factory wired and piped. Dual circuit models feature internally manifolded condensers. CABINET All cabinets are completely constructed of 18 Ga. corrosion resistant "Galvalume" coated steel. The entire unit interior (both evaporator and condensing section) is insulated with 1/2" thick, 2 lbs. density insulation. Service panels are equipped with lifting handles for ease of removal and handling. Duct flanges for return air intake and evaporator discharge are provided with the unit, for field installation. Duct flange on CU240 evaporator return is incorporated into the filter frame. REFRIGERATION CIRCUITS 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. The 5 ton units have a single refrigeration circuit. The 8-20 ton units feature two independent refrigeration circuits. Each refrigeration circuit includes an adjustable thermal expansion valve (with external equalizer), liquid line filter drier, sight glass/moisture indicator, and service gauge ports. The evaporator coils are constructed of internally enhanced copper tubes mechanically bonded to rippled aluminum plate fins. The evaporator coil is employed in a draw-through configuration, and features inter-laced circuiting. Large evaporator coil face area minimizes potential water blow-off. The high-efficiency tube-in-tube condensers feature a convoluted inner tube design for optimum performance. Standard models feature a copper inner tube surrounded by a steel outer tube, and carry a 400 psig working pressure rating. INDOOR FANS Forward curved, double inlet and double width centrifugal blowers are used for evaporator air movement. Large diameter wheels are employed to provide required airflow performance at minimum rpm and noise levels. Blower wheels are fabricated of galvanized steel. Blowers employ solid steel shafts, supported in permanently lubricated ball bearings. 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 evaporator blower 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. Units are designed to operate with conventional thermostat control interface. FILTERS All models are shipped with 2 inch thick medium-efficiency throwaway filters factory installed. Filters are accessible from either front or right side on 5-15 ton models. The CU240 filter rack is external to the cabinet (shipped loose). Unitary Products Group 3

21 SUPPLY AIR/RETURN AIR CONFIGURATION All models are field convertible for multiple supply return configurations. The 5 through 15 ton models feature a removable upper fan module that can be rotated 180 for top rear discharge applications. In addition, the blower outlet panel may be interchanged with the front panel of the fan module. Interchanging these two panels allows horizontal fan discharge to either front or rear of the unit. The blower outlet panel may also be interchanged on the 20 and 25 ton units to provide horizontal discharge. FIGURE 8 - SUPPLY AIR/RETURN AIR CONFIGURATION Unitary Products Group 21
