charge are provided with the unit, for field installation. Duct  
flange on CU240 evaporator return is incorporated into the fil-  
ter frame.  
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.  
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.  
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.  
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.  
3. Brackish or salt water and a secondary heat exchanger.  
They can be installed:  
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.  
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  
INDOOR FANS  
GENERAL  
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.  
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.  
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.  
CABINET  
FILTERS  
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-  
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).

be interchanged with the front panel of the fan module. Inter-  
changing these two panels allows horizontal fan discharge to  
either front or rear of the unit.

CONFIGURATION  
All models are field convertible for multiple supply return con-  
figurations. The 5 through 15 ton models feature a removable  
upper fan module that can be rotated 180for top rear dis-  
The blower outlet panel may also be interchanged on the 20  
and 25 ton units to provide horizontal discharge.

Steam Heating Coils are tube-in-tube ësteam distributingí type to eliminate risk of con-  
densate freezing.  
Coils are constructed of 5/8 inch diameter outer copper tubes, with 3/8 inch diameter  
inner tubes. The outer tube is mechanically bonded to rippled aluminum plate fins. Coil  
casing is fabricated of heavy gauge galvanized sheet. Copper headers are complete  
with MPT connections.  
ï
All coils are 1 row, 8 fins per inch.
