charge are provided with the unit, for field installation. Duct  
flange on CU240 & CU300 evaporator return is incorporated  
into the filter 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. The 25 ton unit has  
three independant 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 “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.  
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:  
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.  
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.  
2. In an equipment room with both supply and return air  
ductwork  
INDOOR FANS  
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 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.  
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.  
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 and  
CU300 filter rack is external to the cabinet (shipped loose).

OVERSIZED EVAPORATOR FAN MOTORS  
WATER SIDE ECONOMIZER  
Increased horsepower motors and drive components are  
available for those applications where external static pres-  
sure requirements exceed the capability of the standard  
motor.  
Commercial Water Cooled Air Conditioners can achieve sub-  
stantial operating cost reductions by utilizing the cooling  
effect made available by low temperature water. The Water-  
side 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.  
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.  
HOT WATER & STEAM COILS  
Hydronic heating coils shall mount on return air side of cool-  
ing coil.  
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.  
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.  
HOT GAS BYPASS  
DISCHARGE PLENUM  
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.  
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 capa-  
bility of the standard motor.  
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.  
CONDENSER PRESSURE CONTROL  
Water regulating valves provide control of the quantity of con-  
denser 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.

charge applications. In addition, the blower outlet panel may  
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.  
SUPPLY AIR/RETURN AIR  
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 180° for 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 ‘steam distributing’ 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.  
All coils are 1 row, 8 fins per inch.
