General
Units are leak and pressure tested at 385 psig high side, 220 psig low side, then evacuated and charged.
Unit panels, structural elements and control boxes are constructed of galvanized steel and mounted on a bolted
galvanized steel base. Unit panels, control boxes and the structural base are finished with a baked on powder paint.
Anytime water only is present in the evaporator, the Trane UC800 controller must have flow control of the chilled water
system. Flow control can be done either directly or through an input to a building automation system to conduct an
action resulting in minimum flow through the chiller evaporator barrel to avoid potentially catastrophic damage to the
evaporator due to freezing. If the system has sufficient glycol to protect down to the lowest expected ambient, flow
control is optional.
A control power transformer shall be factory-installed and factory-wired to provide unit control power.
Chiller is built and certified to UL2014 US and Canadian safety standard.
Power Requirements
Unit is provided with single-point electrical unit power connection. Standard power connection includes main three
phase power to the compressors, condenser fans and control power transformer.
Note: A separate field supplied low voltage power source is required to power the evaporator freeze protection.
Note: An additional separate field supplied low voltage power source is required to power the Convenience Outlet.
Factory Refrigerant Charge (R-134a)
Packaged units ship with a full operating charge of oil and HFC-134a refrigerant.
Evaporator
The evaporator is a tube-in-shell heat exchanger design with internally and externally finned copper tubes roller
expanded into the tube sheets. All tubes can be individually replaced. The evaporator is designed, tested and stamped
in accordance with ASME Pressure Vessel Code Section VIII for a refrigerant side working pressure of 200 psig. The
evaporator is designed for a water side working pressure of 150 psig. Each shell includes a vent, a drain, and fittings for
temperature control sensors. Evaporator water connections are grooved pipe. Evaporator will be configured with a 2
pass arrangement.
Heaters, with thermostat, are provided to help protect the evaporator from freezing at ambient temperatures down to
-4°F, depending on application.
Note: A separate field supplied low voltage power source is required to power the evaporator freeze protection.
Evaporator is insulated with UV resistant 0.75 inch Armaflex II or equal insulation (K=0.28). Insulation also covers the
liquid and suction line and evaporator heads.
Operating Temperatures & Low Ambient Operation
Unit is designed for operation in standard leaving evaporator temperature (equal to or greater than 40.0 °F). Chiller shall
be able to start and operate in ambient conditions down to -4⁰F and up to 115⁰F. Low ambient operation is
accomplished with factory installed and tested protection. Chiller shall be capable of starting up with 90⁰F entering fluid
temperature to the evaporator. Maximum water temperature that can be circulated with the chiller not operating is
104⁰F,
Pressure Vessel Code
Chiller complies with ASME Pressure Vessel Code Section VIII. ASME nameplates are attached to applicable pressure
vessels, including oil separators.
Condenser and Fans
Air-cooled microchannel condenser coils use all aluminum brazed fin construction. The condenser coil will have an
integral subcooling circuit. The maximum allowable working pressure of the condenser is 350 psig. Condensers are
factory proof and leak tested at 525 psig. Coils can be cleaned with high pressure water.
Direct-drive, vertical-discharge condenser fans are dynamically balanced. The condenser fan motors are permanent
magnet motors with integrated drive to provide variable speed fan control for all fans. Units are equipped with EC
condenser fan motors with permanently lubricated ball bearings and external overload and overcurrent protection. The
fan impeller is a 5 bladed-shrouded fan. Fans are insulation IP54 compliant.
Completely assembled coils are dipped and baked in an electro-mechanically bonded flexible epoxy coating. Provides
uniform epoxy coating of all surfaces on microchannel coil. No associated surfaces remain bare. Allows for corrosion
resistance without performance degradation. Coils with coating passed 6000-hour salt spray test.

Standard Noise Sound Package
Unit will be built with low noise condenser fans.
Compressor and Lube Oil System
The rotary screw compressor is semi-hermetic, direct drive with capacity control via an adaptive frequency drive, rolling
element bearings, differential refrigerant pressure oil pump and oil heater. The motor is a suction gas cooled,
hermetically sealed two pole squirrel cage induction motor.
Oil separation is provided to separate oil and refrigerant prior to entrance into condenser to preserve the integrity of heat
transfer in the condenser. Oil filtration is provided internal to the compressor. Check valves in the compressor
discharge and lube oil system are also provided.
Refrigeration Circuits
Each unit has two refrigerant circuits, with one rotary screw compressor per circuit. Each refrigerant circuit includes a
compressor suction and discharge service valve, liquid line shutoff valve, removable core filter, liquid line sight glass
with moisture indicator, charging port and an electronic expansion valve. Fully modulating compressors and electronic
expansion valves provide variable capacity modulation over the entire operating range.
Adaptive Frequency Drive Compressor Starter
Trane's Adaptive Frequency Drive (AFD) technology is specifically designed for Trane air-cooled chillers. The AFD
incorporates the Trane communication protocol enabling seamless integration with the unit controller. The AFD data
such as drive status, temperature modes, and diagnostic information are accessible to the unit controller.
AFD will protect itself and the compressor motor from over current, low or high line voltage, phase loss, incoming phase
imbalance, and over temperature due to loss of panel ventilation.
The AFD incorporates improved serviceability and troubleshooting tools. All AFD control circuits are powered with class
2 low voltage. The drive is air-cooled with a ventilation fan in the panel.
Unit Controls
All unit controls are housed in an outdoor rated weather tight enclosure per UL2014 with removable plates to allow for
customer connection of power wiring and remote interlocks. All controls, including sensors, are factory mounted and
tested prior to shipment.
Microcomputer controls provide all control functions including startup and shut down, leaving chilled water temperature
control, evaporator flow proving, compressor staging and speed control, electronic expansion valve modulation,
condenser fan sequencing and speed control, anti-recycle logic, automatic lead/lag compressor starting, load limiting
and chilled water pump control.
The UC-800 unit control module with Rapid Restart, utilizing Adaptive Control microprocessor, automatically takes
action to avoid unit shutdown due to abnormal operating conditions associated with low refrigerant pressure, high
condensing pressure and motor current overload. Should the abnormal operating condition continue until a protective
limit is violated, the unit will be shut down.
Unit protective functions of the UC-800 include: low evaporator refrigerant pressure, high condenser refrigerant
pressure, low oil flow, critical sensor or detection circuit faults, current overload, high compressor discharge
temperature, communications lost between modules, electrical distribution faults, phase loss, phase imbalance, phase
reversal, external and emergency stop, momentary power loss, under/over voltage, and loss of evaporator water flow.
Unit Mounted Color Touchscreen Display/Interface
A full color TD-7 AdaptiView touch screen display indicates all important unit and circuit parameters, in logical groupings
on various screens. The parameters including chilled water set point, leaving chilled water temperature, demand limit
set point, evaporator and condenser refrigerant temperatures and pressures, compressor and fan speeds, and all
pertinent electrical information. The display also provides on screen trending graphs of predefined parameters as well
as customizable trend graphs based on user defined parameters from a list of all available parameters. The display also
provides indication of the chiller and circuits top level operating modes with detailed sub-mode reports available with a
single key press, as well as diagnostics annunciation and date and time stamped diagnostic history. The standard color
display is fully outdoor rated, and can be viewed in full daylight without opening any control panel doors.

Factory Quality Tests
Compressor Test
All compressors undergo a high pressure test, helium leak check and a mechanical functionality test after compressor
assembly. In addition, a high potential test is performed to check for electrical functionality.
Evaporator Shell Test
Outside the water tank, one circuit is pressurized to 20 psi; the opposite circuit is checked for pressure. Then the shell is
loaded into the water tank. Both circuits are pressurized to 1.1 maximum allowed working pressure (MAWP); 200 psi x
1.1 = 220 psi and held for 1 minute. Then, the pressure is dropped to equal MAWP, the vessel is removed from the water
tank, soap/water visually inspected for leaks (bubbles) at all the weld and tube roll joints (outside tube sheets).
Evaporator Vacuum Test
Refrigerant shell side on one circuit of evaporator is vacuumed to at least 250 microns and pressure is added to the
opposite circuit. The vacuum is held in the evaporator for five minutes. Vacuum in evaporator shall not rise more than 25
microns per minute. Any rise above 25 microns indicates a leak.
Evaporator Water Box Test
After evaporator water box installation, water lines are attached. The evaporator is then filled with water and pressurized
to 1.5 times the maximum allowable working pressure or 225 psig. The joints between the water box and evaporator
shell are then visually inspected to verify no leaks are present.
General Assembly Proof
After completing assembly, the high and low side of the unit is pressure tested to 385 and 220 psig respectively. A visual
inspection and soap bubble test is performed followed by a helium leak check at 110 psig before the unit is evacuated
and charged.
General Assembly Vac-Rise Test
Each circuit within the unit is evacuated to 250 microns. This value shall not increase more than 125 microns
in ten minutes. Any rise above 125 microns indicates a leak or contamination.
End-of-Line Functionality Test
After fully assembled and charged with refrigerant, the unit is checked for electrical component functionality. A high
potential test is performed in which a voltage equal to 1.2 X (2*Rated Voltage + 1000) is run through each component of
both the power and controls circuits for 1 second to test for shorted lines and leakage current. A fully functional electrical
test including condenser fans is performed.
Factory Witness Performance Test
A 5 point witness test will be conducted in the presence of the customer's designated witness at customer specified
ambient and water temperature conditions to certify chiller performance before shipment. A test report showing actual
performance at specified parameters is provided. Testing will be performed in accordance with AHRI Standard
550/590. Upon test completion, the customer and factory witness will sign the report and a copy will be provided to the
customer.
