271846-YTG-B-0208

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 “cooling only” 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 “free standing” 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 ‘straight-through’ 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 dis-

charge are provided with the unit, for field installation. Duct flange on CU240 & CU300 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. The 25 ton unit has three independant 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 and CU300 filter rack is external to the cabinet (shipped loose).

FACTORY INSTALLED

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

Evaporator coil shall receive a 1-mil thickness of a cathodic epoxy type electro-deposition coating, applied in a multiple dip and bake process.

STAINLESS STEEL DRAIN PAN

Evaporator coil (and optional Water Side Economizer coil) drain pan shall be fabricated 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 factory installed Condenser Pressure Control option is strongly recommended when Hot Gas Bypass is installed.

ANTI-SHORT CYCLE TIMER

Time delay relay will be provided for each compressor circuit. Compressor will be lock out for 5 minutes when thermostat contacts open, or there is a momentary power outage.

FIELD INSTALLED

WATER SIDE ECONOMIZER

Commercial Water Cooled Air Conditioners can achieve substantial operating cost reductions by utilizing the cooling effect made available by low temperature water. The Waterside Economizer Kit consists of a field installed water cooling coil, pre-assembled external piping sections, a three-way motorized valve, and all necessary controls for unit operation from a conventional 24-Volt thermostat.

HOT WATER & STEAM COILS

Hydronic heating coils shall mount on return air side of cooling coil.

RETURN AIR GRILL

Available on 5-15 ton CU models only. Recommended for applications where return air is not ducted and air is drawn directly from the conditioned space.

DISCHARGE PLENUM

Plenums mount on top of the evaporator section, with fans arranged for vertical discharge. Double deflection grills shall allow air discharge in multiple directions.

OVERSIZED EVAPORATOR FAN MOTORS

Increased horsepower motors and drive components are available as a kit. Units are field upgradeable for applications where external staic pressure requirements exceed the capability of the standard motor.

CONDENSER PRESSURE CONTROL

Water regulating valves provide control of the quantity of condenser water supplied to the unit by sensing the condensing temperature. The field installed Condenser Control Option provides a regulating valve for each internal condenser water circuit. Standard Water Regulating Valve carries a 150 psig working pressure rating. The valve is installed inside of the unit cabinet.
