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 wir- ing, 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 convert- ible 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 conden- sate drain connections are via female pipe thread fittings.

All models 5 -25 tons ship as factory-charged unitized pack- ages. The 5 -15 ton units may be field split between the evap- orator /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 han- dling. Duct flanges for return air intake and evaporator dis-

charge are provided with the unit, for field installation. Duct flange on CU240 evaporator return is incorporated into the fil- ter frame.

REFRIGERATION CIRCUITS

All models utilize "Scroll" type hermetic compressors. Com- pressors are mounted on rubber isolators to minimize vibra- tion 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 cir- cuit 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 con- figuration, and features inter-laced circuiting. Large evapora- tor coil face area minimizes potential water blow-off.

The high-efficiency tube-in-tube condensers feature a convo- luted 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 diame- ter wheels are employed to provide required airflow perfor- mance 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 con- trols. 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 pres- sure cutout. A 24 volt control circuit, with oversize trans- former, 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).
