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 “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
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 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 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.
-
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-

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 capa
bility 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.

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 dis-
charge 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.

• Steam Heating Coils are tube-in-tube ‘steam distributing’ type to eliminate risk of condensate 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 coil s are 1 row, 8 fins per inch.
