Warnings, Cautions, and NoticesSafety advisories appear throughout this manual asrequired. Your personal safety and the properoperation of this machine depend upon the strictobservance of these precautions.

The three types of advisories are defined as follows:

WARNINGIndicates a potentially hazardous situationwhich, if not avoided, could result in death orserious injury.

CAUTIONIndicates a potentially hazardous situationwhich, if not avoided, could result in minor ormoderate injury. It could also be used to alertagainst unsafe practices.

NOTICEIndicates a situation that could result inequipment or property-damage onlyaccidents.

Important Environmental ConcernsScientific research has shown that certain man-madechemicals can affect the earth’s naturally occurringstratospheric ozone layer when released to theatmosphere. In particular, several of the identifiedchemicals that may affect the ozone layer arerefrigerants that contain Chlorine, Fluorine and Carbon(CFCs) and those containing Hydrogen, Chlorine,Fluorine and Carbon (HCFCs). Not all refrigerantscontaining these compounds have the same potentialimpact to the environment. Trane advocates theresponsible handling of all refrigerants-includingindustry replacements for CFCs and HCFCs such assaturated or unsaturated HFCs and HCFCs.

Important Responsible RefrigerantPracticesTrane believes that responsible refrigerant practicesare important to the environment, our customers, andthe air conditioning industry. All technicians whohandle refrigerants must be certified according to localrules. For the USA, the Federal Clean Air Act (Section608) sets forth the requirements for handling,reclaiming, recovering and recycling of certainrefrigerants and the equipment that is used in theseservice procedures. In addition, some states ormunicipalities may have additional requirements thatmust also be adhered to for responsible managementof refrigerants. Know the applicable laws and followthem.

Unit NameplateThe unit nameplate is located on the right side of thecontrol panel. A typical unit nameplate is illustrated inthe following figure and contains the followinginformation:

• Unit model and size descriptor

• Unit serial number

• Unit electrical requirements

• Correct operating charge and refrigerant type

• Unit test pressures and maximum operatingpressures

• Unit literature

• Drawing numbers for unit wiring diagrams

SSeerriiaall NNuummbbeerr.. The unit serial number provides thespecific chiller identity. Always provide this serialnumber when calling for service or during partsidentification.

SSeerrvviiccee MMooddeell NNuummbbeerr.. The service model representsthe unit as built for service purposes. It identifies theselections of variable unit features required whenordering replacements parts or requesting service.

NNoottee:: Unit-mounted Adaptive Frequency™ Drives(AFDs) are identified by a separate number; referto “Model Number Descriptions,” p. 8.

PPrroodduucctt DDeessccrriippttiioonn BBlloocckk.. The Agility™ chillermodels are defined and built using the ProductDefinition and Selection (PDS) system. This systemdescribes the product offerings using a product codingblock which is made up of feature categories and codesthat identify all characteristics of a unit.

Pre-installationASHRAE Standard 15ComplianceTrane recommends that indoor Agility™ chillerinstallations fully meet or exceed the guidelines of thecurrent version of ASHRAE Standard 15, in addition toany applicable national, state, or local requirements.This typically includes:

• A refrigerant monitor or detector that is capable ofmonitoring and alarming within the acceptableexposure level of the refrigerant, and that canactuate mechanical ventilation.

• Audible and visual alarms, activated by therefrigerant monitor, inside the equipment room andoutside of every entrance.

• The equipment room should be properly vented tothe outdoors, using mechanical ventilation that canbe activated by the refrigerant monitor.

• If required by local or other codes, a self-containedbreathing apparatus should be available in closeproximity to the equipment room.

Refer to the latest copy of ASHRAE Standard 15 forspecific guidelines. Trane assumes no responsibility forany economic, health, or environmental issues thatmay result from an equipment room’s design orfunction.

Installation: MechanicalLocation RequirementsSound Considerations• Install rubber vibration isolators in all water piping.

• Isolate all pipe hangers and be sure they are notsupported by main structure beams that couldintroduce vibration into occupied spaces.

• Make sure that the piping does not put additionalstress on the unit.

NNoottee:: Do not use metal braided type eliminators onthe water piping. Metal braided eliminatorsare not effective at the frequencies at whichthe unit will operate.

• Use flexible electrical conduit.

• Seal all wall penetrations.

NNoottee:: Consult an acoustical engineer for criticalapplications.

Foundation RequirementsChiller mounting surface must be:

• rigid non-warping mounting pads or a concretefoundation, and

• able to support the chiller at its full operatingweight (including completed piping and fulloperating charges of refrigerant and water).

For proper unit operation, the chiller must be levelwithin 1/4 in. (6.35 mm) over its length and width whenset into place on the mounting surface. Refer to“Leveling the Unit,” p. 21 for more information. Forminimum and maximum chiller weights/dimensions inpounds/inches and kilograms/millimeters, refer to“Weights (lb),” p. 14 and “Weights (kg),” p. 15,respectively.

NNoottee:: For specific weight information, refer to the unitsubmittal package.

IImmppoorrttaanntt:: Trane will not assume responsibility forequipment problems resulting from animproperly designed or constructedfoundation.

ClearancesProvide enough space around the unit to allow theinstallation and maintenance personnel unrestrictedaccess to all service points. Refer to submittal drawingsfor the unit dimensions.

Refer to “Unit Clearances,” p. 13 for minimumclearances required for service. In all cases, local codeswill take precedence over these recommendations.

VentilationThe unit produces heat even though the compressor iscooled by the refrigerant. Make provisions to removeheat generated by unit operation from the equipmentroom. Ventilation must be adequate to maintain anambient temperature lower than 104°F (40°C).

Vent the evaporator, condenser, and compressorpressure relief valves in accordance with all local andnational codes. Refer to “Refrigerant Pressure ReliefValve Venting,” p. 21.

Make provisions in the equipment room to keep thechiller from being exposed to freezing temperatures(32°F [0°C]).

Water DrainageLocate the unit near a large capacity drain for watervessel drain-down during shutdown or repair.Condensers and evaporators are provided with drainconnections. Refer to “Overview,” p. 25. All local andnational codes apply.

Access RestrictionsDoor clearances are provided in “Unit Clearances,” p.13. See unit submittals for specific "per unit"dimensional information.

Operating EnvironmentIImmppoorrttaanntt::

• The standard chiller is designed forINDOOR USE ONLY and as such hasNEMA Type 1 enclosures.

• The warranty requires an equipmentroom/chiller environment surroundingthe NEMA 1 chiller to be maintained inthe temperature range of 34°F to 104°F(1.1°C to 40°C) AND at less than 95%relative humidity (non-condensingconditions).

NNoottee:: Disassembly and reassembly work includesremoving the compressor from the unit.Contact Trane or an agent of Tranespecifically authorized to perform start-upand warranty of Trane® products for specificrigging instructions. Do NOT attempt torotate the chiller onto its side.

• When lifting the chiller is either impractical orundesirable, machinery dollies should be placedunder the supports; then push or pull the unitacross a smooth surface. Should the chiller be onblocks, it is not necessary to remove the blocksfrom the chiller before moving it into place.

• Use care on uneven surfaces. Piping in the center ofthe unit is within 1/2 in. (12.7 mm) of the ground.

Unit IsolationTo minimize sound and vibration transmission throughthe building structure and to ensure proper weightdistribution over the mounting surface, Tranerecommends installing isolation padding under thechiller feet. For seismic installations, refer to thespecific installation details provided by the foundationdesigner.

NNoottee:: Isolation pads are provided with each chiller.

Specific isolator loading data is provided in the unitsubmittal package. If necessary, contact your localTrane sales office for further information.

IImmppoorrttaanntt:: When determining placement of isolationpads, remember that the control panel sideof the unit is always designated as the frontside of the unit.

Isolation PadsWhen isolation pads are used, place them under eachof the eight individual mounting points. The pads may

Installation: Water PipingOverviewThe following water piping circuits must be installedand connected to the chiller:

• Pipe the evaporator into the chilled water circuit.

• Pipe the condenser into the cooling tower watercircuit.

NNoottee:: Piping must be arranged and supported to avoidstress on the equipment. It is stronglyrecommended that the piping contractor doesnot run pipe closer than 3 ft (0.9 m) minimum tothe equipment. This will allow for proper fit uponarrival of the unit at the job site. Any adjustmentthat is necessary can be made to the piping atthat time. Expenses that result from a failure tofollow this recommendation will NOT be paid byTrane.

Piping suggestions for each of the water circuits listedabove are outlined in “Evaporator and CondenserWater Piping,” p. 28. General recommendations for theinstallation of field-supplied piping components (e.g.,valves, flow switches, etc.) common to most chillerwater circuits are listed in the following sections.

Water TreatmentThe use of untreated or improperly treated water in aAgility™ chiller may result in inefficient operation andpossible tube damage.

IImmppoorrttaanntt:: Trane strongly recommends using theservices of a qualified water treatmentspecialist to determine necessary watertreatment. A label with a customerdisclaimer note is affixed to each unit.

To determine whether or not pressure relief valvesare needed for a specific application, keep in mindthat:

a. Vessels with close-coupled shutoff valves maycause high potentially damaging hydrostaticpressures as fluid temperature rises.

b. Relief valves are required by American Societyof Mechanical Engineers (ASME) codes whenthe shell waterside is ASME. Follow ASMEguidelines or other applicable codes to ensureproper relief valve installation.

Piping must be arranged and supported to avoid stresson the equipment. It is strongly recommended that thepiping contractor does not run pipe closer than 3 ft(0.9 m) minimum to the equipment. This will allow forproper fit upon arrival of the unit at the job site. Anyadjustment that is necessary can be made to the pipingat that time. Expenses that result from a failure tofollow this recommendation will NOT be paid by Trane.

Water piping connection sizes and components areidentified in the tables in “Water PipingConnections,” p. 29 and “Grooved Pipe Coupling,” p.30. Remember that with many waterboxes, theentering and leaving evaporator water can be piped toeither waterbox connection when the tube bundles aresplit vertically. However, large evaporator waterboxeswith entering and leaving connections not at the samelevel must be connected with the entering water at thebottom and the leaving water at the top.

Waterboxes with multiple pass arrangements utilize abaffle to separate the passes. These baffles aredesigned for a maximum pressure of 20 psid(137.9 kPaD). If larger pressure drops are expected inthe application, contact your local Trane representativeto discuss special waterbox options.

IImmppoorrttaanntt:: Water flows must be piped in accordancewith nameplate designation.

Field-provided isolation valves for the evaporator andcondenser water lines should be installed upstreamand downstream of the heat exchangers, and beinstalled far enough away from the chiller to alsoprovide practical service isolation for flow sensingdevices, field thermometers, flexible connectors, andany removable pipe spools.

Ensure that the evaporator water piping is clear; checkit after the chilled water pump is operated but beforeinitial chiller start-up. If any partial blockages exist, theycan be detected and removed to prevent possible tubedamage resulting from evaporator freeze-up orerosion.

For condenser and evaporator connections, arrangethe water piping so that the water supply enters theshell at the lower connection and exits from the topconnection. Operational problems may result if thispiping is not correct.

For applications that include an “infinite source” or“multiple-use” cooling condenser water supply, installa valved bypass “leg” (optional) between the supplyand return pipes. This valved bypass allows theoperator to short-circuit water flow through the coolingcondenser when the supply water temperature is toolow.

Water Piping ConnectionsAll standard units use grooved-pipe connections.These are grooved-end NSP (Victaulic® style) pipeconnections. Flanged connections are optional.

Piping joined using grooved type couplings, like alltypes of piping systems, requires proper support tocarry the weight of pipes and equipment. The supportmethods used must eliminate undue stresses on joints,piping, and other components, allow movement whererequired, and provide for any other specialrequirements (i.e., drainage, etc.).

NNoottee:: If needed, plug-type sensor extension cables areavailable for purchase from Trane Parts Service.These sensor extension cables may be necessaryif the waterboxes are changed or if thetemperature sensors are moved out into the unitpiping for better mixed temperature readings.

Waterbox LocationsNNoottee:: Do NOT interchange evaporator and condenser

waterboxes. Supply evaporator waterbox andtubesheet contain match marks to aid inidentifying matching shells and waterboxes.

If removal of waterboxes is necessary, refer to“Waterbox Removal,” p. 65.

If the waterboxes on any of the shells are exchangedend-for-end, be sure to reinstall them right-side up to

maintain the correct baffle arrangements. Use a newgasket with each waterbox cover.

Reversing WaterboxesAll waterboxes can be reversed end-for-end. Refer to“Waterbox Removal,” p. 65 for detailed waterboxremoval instructions.

Remove sensors from wells before removingwaterbox.

Do NOT rotate waterboxes.

Complete the waterbox switch and replace sensors.

NNootteess::

• If waterboxes are reversed, be sure toproperly rewire water temperature sensorsin the control panel.

• Be sure to replace waterboxes right-side-upto maintain proper baffle orientation. Usenew O-rings.

• if the waterbox is revered, be sure to matchmark on the baffle and the waterbox toensure they are aligned.

Grooved Pipe CouplingA customer-supplied, standard flexible grooved pipecoupling (Victaulic® Style 77 or equivalent) should beused to complete the Victaulic® connection for both150 psig (1034.2 kPaG) and 300 psig (2068.4 kPaG)waterboxes.

When a flexible coupling such as this is installed at thewaterbox connections, other flexible piping connectors(i.e., braided-steel, elastomeric arch, etc.) are notusually required to attenuate vibration and/or preventstress on the connections.

When flat-face flange connections are specified, flange-to-groove adapters are provided (Victaulic® Style 741 ,150 psig [1034.2 kPaG]). The adapters are shipped inspare parts box included with the unit. Adapterdescriptions are given in the tables in “Victaulic GasketInstallation,” p. 31. The flange adapters provide adirect, rigid connection of flanged components to thegrooved-pipe chiller waterbox connections.

In this case, the use of flexible type connectors (i.e.,braided steel, elastomeric arch, etc.) are recommendedto attenuate vibration and prevent stress at thewaterbox connections.

All flange-to-flange assembly screws must be providedby the installer. Hex head screw sizes and numberrequired are included in the tables in “Victaulic GasketInstallation,” p. 31. The Style 741 (150 psig[1034.2 kPaG]) flange adapter requires a smooth, hardsurface for a good seal.

Connection to other type flange faces (i.e., raised,serrated, rubber, etc.) requires the use of a flangewasher between the faces. Refer to the flange adaptermanufacturer’s guidelines for specific information.

Victaulic Gasket Installation1. Inspect supplied gasket to be certain it is suited for

intended service (code identifies gasket grade).Apply a thin coat of silicone lubricant to gasket tipsand outside of gasket.

2. Install gasket, placing gasket over pipe end andmaking sure gasket lip does not overhang pipe end.Refer to the following figure for gasketconfiguration.

3. Align and bring two pipe ends together and slidegasket into position centered between the grooveson each pipe. No portion of the gasket shouldextend into the groove on either pipe.

4. Open fully and place hinged Victaulic® flangearound the grooved pipe end with the circular keysection locating into the groove.

5. Insert a standard hex head screw through themating holes of the Victaulic® flange to secure theflange firmly in the groove.

6. Tighten fasteners alternately and equally untilhousing screw pads are firmly together (metal-to-metal); refer to “Screw-Tightening Sequence forWater Piping Connections,” p. 31. Do NOTexcessively tighten fasteners.

NNoottee:: Uneven tightening may cause the gasket topinch.

Waterside design pressure is 150 psig (1034.2 kPaG).

Eddy Current TestingTrane recommends conducting an eddy currentinspection of the condenser and evaporator tubes in

water-cooled chillers every three years. Eddy currenttests are intended to identify defects on or within thewalls of heat exchanger tubing that could lead to in-service tube failures. Eddy current tests conductedbefore a chiller is put into service are considered“baseline” eddy current tests, and are intended toestablish a reference point to aid in the interpretation offuture eddy current test reports. Many of the anomaliesthat can be found through eddy current testing have noimpact on tube life or performance, while others aresevere enough to justify removing the affected tubefrom service. Ask your sales account manager for acopy of the engineering bulletin (CTV-PRB024*-EN) forclarification of the role of eddy current testing in chillermaintenance by providing information about eddycurrent technology and heat exchanger tubing.


HDWA-SVX001D-EN 33

InsulationUnit Insulation RequirementsFactory-installed insulation is available as an option forall units. Factory installation does NOT includeinsulation of the chiller feet. In applications where thechiller is not factory-insulated, install insulation over allsurfaces shown in the figure in “Factory-appliedInsulation,” p. 33 (i.e., compressor, condenser,economizer, and drive [not shown]).

The quantity of insulation required is listed in thefollowing table. Insulation thickness is determined atnormal design conditions which are:

• Standard comfort-cooling leaving chilled watertemperature

• 85°F (29.4°C) dry bulb ambient temperature

• 75 percent relative humidity

Operation outside of normal design conditions asdefined in this section may require additionalinsulation; contact Trane for further review.

NNoottee:: If the unit is not factory-insulated, installinsulation around the evaporator bulbwells andensure that the bulbwells and connections forthe waterbox drains and vents are still accessibleafter insulation is applied. The sensor modules(Low Level Intelligent Devices [LLIDs]) andinterconnecting four-wire cable inter-processorcommunication (IPC) bus must be raised upabove the field-installed insulation. Secure theIPC bus to the insulation top/outer surface afterinsulation is completed.

IImmppoorrttaanntt:: Do NOT insulate the compressor, motorhousing, unit wiring, or sensor modules.

HDWA-SVX001D-EN 47

Operating PrinciplesGeneral RequirementsOperation and maintenance information for HDWAAgility™ chillers are covered in this section. Bycarefully reviewing this information and following theinstructions given, the owner or operator cansuccessfully operate and maintain a Agility™ chiller. Ifmechanical problems do occur, however, contact aTrane service technician to ensure proper diagnosisand repair of the unit.

IImmppoorrttaanntt::

• Although Agility™ chillers can operatethrough surge, it is NOT recommendedto operate them through repeatedsurges over long durations. If repeatedsurges of long durations occur, contactyour Trane Service Agency to resolvethe issue.

• Agility™ are selected, designed, andbuilt for a particular set of designconditions. Operation outside of designconditions may result in improperoperation. Refer to chiller selection forminimum unloading.

Cooling CycleWhen in the cooling mode, liquid refrigerant isdistributed along the length of the evaporator andsprayed through small holes in a distributor (i.e.,running the entire length of the shell) to uniformly coateach evaporator tube. Here, the liquid refrigerantabsorbs enough heat from the system water circulatingthrough the evaporator tubes to vaporize. The gaseousrefrigerant is then drawn through the suctionconnection and the first-stage variable inlet guidevanes, and into the first-stage impeller.

HDWA CompressorThe unit is equipped with a semi-hermetic, direct-drive,two-stage, centrifugal compressor that includes inletguide vanes for capacity control. The AdaptiveFrequency™ Drive (AFD) provides capacity control withlower speeds. Compressed gas from the first-stageimpeller is discharged through the interstage pipe tothe second-stage impeller. Here, the refrigerant gas isagain compressed, and then discharged into thecondenser. Baffles within the condenser shell distributethe compressed refrigerant gas evenly across thecondenser tube bundle. Cooling tower water circulatedthrough the condenser tubes absorbs heat from therefrigerant, causing it to condense. The subcooledliquid refrigerant then flows out of the bottom of thecondenser.

The liquid refrigerant is then split such that the primaryflow is directed through one side of the brazed plate

heat exchanger economizer, while a significantlysmaller portion of the flow passes through anexpansion valve, lowering refrigerant pressure andtemperature before entering the secondary side of theBPHE as two-phase refrigerant. The heat transferbetween the primary and secondary channels in theBPHE results in further subcooling of the primary liquidas it rejects heat to, and consequently superheats, thesecondary flow. The additional subcooling of the liquidprior to expansion through the main electronically-controlled valve effectively increases the overallcapacity of the evaporator. In addition, the superheatedvapor bypasses the evaporator and first stage ofcompression (the secondary BPHE flow is added priorto the second stage of compression).

Compressor MotorTwo magnetic bearing modules levitate and align therotating assembly. The motor is permanent magnettype and is cooled by refrigerant gas sourced from theinterstage pipe, metered through an orifice orelectronic expansion valve, and routed through thebearing modules and motor windings.

Adaptive Frequency DriveAn Adaptive Frequency™ Drive (AFD) and controlpanel is provided on every chiller. Microprocessor-based unit control modules (Tracer® UC800) providefor accurate chilled water control as well as monitoring,protection, and adaptive limit functions. The "adaptive"nature of the controls intelligently prevents the chillerfrom operating outside of its limits, or compensates forunusual operating conditions, while keeping the chillerrunning rather than simply tripping due to a safetyconcern. When problems do occur, diagnosticmessages assist the operator in troubleshooting.

48 HDWA-SVX001D-EN

Uninterruptible Power SupplyAgility™ chillers contain an on-line double-conversionUninterruptible Power Supply (UPS) to ensure that thecompressor’s magnetic bearing system continues tofunction in the event of an power failure. The UPS (2T5)provides power to the UC800 controls for 90 secondswhile the compressor coasts to a stop. When linepower fails, power is supplied to the UPS with aninternal battery.

When power is removed, or if the chiller’s disconnectswitch is turned off, the UPS will supply power to theUC800 controls for 90 seconds and then the UPS willde-activate. The UPS’s internal battery is notcompletely discharged so that when power is restored,the battery can provide enough power for additionalshutdowns.

The UPS has a fault indicator that is wired to a UC800controls Low Level Intelligent Device (LLID; 1K3). If theUPS indicates a fault, an immediate shutdowndiagnostic will be announced on the UC800 controls.

The following UPS issues could cause this diagnostic:

• EPO Protection

• Busbar Voltage Fault

• IGBT Over-Temperature

• Fan Fault

• Battery Fault

• Output Fault

• Multiple Inverting Fault

Evaporator and CondenserHeat exchangers are shell and tube design. Standardtubes are externally finned, internally enhancedseamless copper with lands at all tube sheets. All tubesheets are made of carbon steel. Tubes aremechanically expanded into tube sheets andmechanically fastened to tube supports. Evaporatorand condenser tubes are 0.75-in. (19.05-mm) diameter.All tubes can be individually replaced.

Shells are carbon steel plate. The evaporator isdesigned, tested, and stamped in accordance with

ASME Code for refrigerant-side/working-side pressureof 200 psig (1379.0 kPaG). The condenser is designed,tested, and stamped in accordance with ASME Codefor refrigerant-side/ working-side pressure of 300 psig(2068.4 kPaG).

All water pass arrangements are available withgrooved connections (150 psig [1034.2 kPaG] watersideworking pressure). All connections may be either right-or left-handed. Waterside shall be hydrostaticallytested at 1.5X design working pressure.

Drive Cooling SystemThe drive cooling system rejects heat through a hybridair and fluid heat sink. The Adaptive Frequency™ Drive(AFD) controls the fan speed to reject some of the heatwhile the refrigerant expansion valve modulates tomaintain a fluid supply temperature to reject theremaining heat.

Drive cooling circuit includes a wet rotor circulationpump that circulates a secondary heat transfer fluid in aclosed system through the AFD heat sinks, output loadinductor and a brazed plate heat exchanger. The pumpis fed from a thermal expansion tank with a vented-pressure cap which is also used as the circuit pressurerelief. The circuit also includes a particulate strainerand a drain valve for servicing.

Tracer AdaptiView DisplayInformation is tailored to operators, servicetechnicians, and owners.

When operating a chiller, there is specific informationyou need on a day-to-day basis—setpoints, limits,diagnostic information, and reports.

Day-to-day operational information is presented at thedisplay. Logically organized groups of information—chiller modes of operation, active diagnostics, settings,graphs, and reports put information conveniently atyour fingertips.

Limit ConditionsThe UC800 will automatically limit certain operatingparameters during startup and run modes to maintain

optimum chiller performance and prevent nuisancediagnostic trips. These limit conditions are noted in thefollowing table.

Table 15. Limit conditions

Condition Description

Running - Limit The chiller, circuit, and compressor are currently running, but the operation of the chiller/compressor is being activelylimited by the controls. Further information is provided by the sub-mode.

Condenser PressureLimit

The circuit is experiencing condenser pressures at or near the condenser limit setting. The compressor will be unloaded toprevent exceeding the limits.

EvaporatorRefrigerantTemperature Limit

The circuit is experiencing saturated evaporator temperatures at or near the Low Refrigerant Temperature Cutout setting.The compressors will be unloaded to prevent tripping.

Current LimitThe compressor is running and its capacity is being limited by high currents. The current limit setting is 100% RLA (to avoidovercurrent trips).

AFD Heat SinkTemperature Limit This limit will unload the chiller if the communicated heat sink temperature approaches cutout.

Demand Limit This limit allows the customer to control the maximum power into the chiller.

Control Panel Devices and Unit-Mounted DevicesUnit Control PanelSafety and operating controls are housed in the unitcontrol paneland the starter panel. The control paneloperator interface is called Tracer® AdaptiView™ andis located on an adjustable arm connected to the sideof the control panel. For more information aboutoperating Tracer® AdaptiView™, refer to TracerAdaptiView Display for Water-cooled Agility ChillersOperations Guide (HDWA-SVU001*-EN).

The control panel houses several other controlsmodules called panel-mounted Low Level IntelligentDevices (LLIDs), power supply, terminal block, fuse,circuit breakers, and transformer. The inter-processorcommunication (IPC) bus allows the communicationsbetween LLIDs and the UC800. Unit-mounted devicesare called frame-mounted LLIDs and can betemperature sensors or pressure transducers. TheMODBUS® master connection on the UC800 providescommunication to the TR200 AFD and to the MagneticBearing Controller (MBC). These and other functionalswitches provide analog and binary inputs to thecontrol system.

If required, after the system has been operating forapproximately 30 minutes and has become stabilized,complete the remaining start-up procedure, as follows:

1. Check evaporator and condenser refrigerantpressures under Condenser and Evaporator Reportson the Tracer® AdaptiView™. The pressures arereferenced to sea level (14.6960 psia [101.3254kPaA]).

Temporary Shut-down and RestartTo shut down for a short time, use the following

procedure:

1. Press the STOP key on the Tracer® AdaptiView™.

2. UC800 pump control will turn off the pump (after aoptional water pump delay time) when the STOPkey is pressed and automatically restart the pumpwhen the “Auto” key is pressed.

3. The unit will start normally, provided the followingconditions exist:

a. The UC800 receives a call for cooling and thedifferential-to-start is above the setpoint.

b. All system operating interlocks and safetycircuits are satisfied.

Extended Unit Shut-down1. Perform the normal unit stop sequence using the

STOP key.

NNoottee:: Unless the water bundles are valved off anddrained, chiller power should remain ON atall times to allow the magnetic bearings tolevitate the rotor in case water flow-drivenrotation should occur. Trane recommendsleaving the power on to maintain theUninterruptible Power Supply (UPS) battery.

2. Verify the chilled water and condenser waterpumps are cycled off. If desired, open disconnectswitches to the pumps.

3. Drain the condenser piping and cooling tower.

4. Remove the drain and vent plugs from thecondenser headers to drain the condenser.

5. After the unit is secured, perform the maintenanceidentified in the following sections.

Seasonal Unit Start-up1. Close all drain valves and reinstall the drain plugs in

the evaporator and condenser headers.

2. Service the auxiliary equipment according to thestart-up and maintenance instructions provided bythe respective equipment manufacturers.

3. Vent and fill the cooling tower, if used, as well asthe condenser and piping. At this point, all air mustbe removed from the system (including each pass).Then, close the vents in the condenser chilled watercircuits.

4. Open all of the valves in the evaporator chilledwater circuit.

5. If the evaporator was previously drained, vent andfill the evaporator and chilled water circuit. After allair is removed from the system (including eachpass), install the vent plugs in the evaporatorwaterboxes.

Recommended MaintenanceWeeklyWhile the unit is running in stable conditions:

☐ Log the chiller.

☐ Check evaporator and condenser pressures withgauges and compare to the reading on the Tracer®AdaptiView™ or Tracer® TU service tool. Pressurereadings should fall within operating rangesspecified in the following tables. If chillermeasurements vary significantly from values listedin the following tables, problems may exist withrefrigerant charge levels. Contact your local TraneService Agency.

NNoottee:: Optimum condenser pressure is dependenton condenser water temperature, and shouldequal saturation pressure of refrigerant at atemperature 2°F to 5°F (1.1°C to 2.8°C) abovethat of leaving condenser water at full load.

Monthly☐ Review operating log.

☐ Clean all water strainers in both the chilled andcondensing water piping systems.

AnnualContact your local Trane Service Agency to shut downthe chiller once each year and perform the following:

☐ Perform all weekly and monthly maintenanceprocedures.

☐ Leak check the chiller, inspect safety controls, andinspect electrical components, such as magnetic

bearing controller and Uninterruptible PowerSupply (UPS).

☐ Inspect all piping components for leakage and/ordamage. Clean out any in-line strainers.

☐ Clean and repaint any areas that show signs ofcorrosion.

☐ Inspect vent piping of all relief valves for presenceof refrigerant to detect improperly sealed reliefvalves.

☐ Inspect the condenser tubes for fouling. Clean ifnecessary; refer to “Cleaning the Condenser,” p.64.

☐ Visually inspect waterbox hinges to ensure thathinges have not been damaged or altered.

NNoottee:: If, after 10 years, the battery has not beenreplaced, Trane recommends replacingthe battery.

Other☐ Use a nondestructive tube test to inspect the

condenser and evaporator tubes at 3-year intervals.

NNoottee:: It may be desirable to perform tube tests onthese components at more frequent intervals,depending upon chiller application. This isespecially true of critical process equipment.

Ask your Sales account manager for a copy ofengineering bulletin (CTV-PRB024*-EN) forclarification of the role of eddy current testing inchiller maintenance by providing informationabout eddy current technology and heatexchanger tubing.

☐ Depending on chiller duty, contact your local TraneService Agency to determine when to conduct acomplete examination of the unit to determine thecondition of the compressor and internalcomponents.

5 years Drain and replace the drive cooling fluid

5 years Replace the fluid strainer when servicing the fluid

Yearly Perform a fluid pH test.

Unit DiagnosticsAn improperly filled drive cooling system (either lowfluid level or entrapped air in the circuit) can result inthe AFD or output filter overheating. This conditionmay result in the following diagnostics:

• AFD Fault

• Loss of Drive Cooling Control

If chiller diagnostics indicate a drive cooling systemproblem, contact your local Trane Service Agency.

pH TestObtain a sample of fluid from the drive cooling loop viathe loop drain located near the discharge of the pump.Test for pH level using litmus paper with a 0.5resolution.

• pH < 8 indicates fluid to be changed

Pressure Relief CapThe pressure relief cap is an automotive style pressure-vent radiator cap; refer to the following figure. Thesetting for the relief spring is 16 lb (7.3 kg). The functionof the relief cap can be verified with a standardautomotive radiator cap tester.

Figure 44. Pressure relief cap

Drive Cooling Expansion TankProper fluid level is important to the operation of theunit. To verify proper level, inspect the liquid level inthe fluid reservoir (located on the left side of theelectrical panel); refer to the following figure for fluidlevels under various temperature conditions. If levelsare low, contact your local Trane Service Agency.

Minimum Fill at 70°F (21.1°C)

NNoottee:: Fill lines are NOT marked on the tank. The toplevel is just below the upper fitting and thebottom level is just above the lower fitting; themiddle level is midway between the two fittings.

Cleaning the CondenserCondenser tube fouling is suspect when the“approach” temperature (i.e., the difference between

MMaaiinntteennaannccee

HDWA-SVX001D-EN 65

the refrigerant condensing temperature and the leavingcondenser water temperature) is higher than predicted.

Condenser tube fouling is indicated when the approachtemperature (the difference between the condensingrefrigerant temperature and the leaving condenserwater temperature) is higher than predicted. Refer tosales order selection data for approach temperatures.

NNoottee:: Glycol in the water system typically doubles thestandard approach.

If the annual condenser tube inspection indicates thatthe tubes are fouled, two cleaning methods(mechanical or chemical) can be used to rid the tubesof contaminants. The methods are described in thefollowing sections.

Mechanical CleaningMechanical tube cleaning is used to remove sludge andloose material from smooth-bore condenser tubes.

Obtain the required parts from your local Trane PartsCenter.

Chemical CleaningScale deposits are best removed by chemical means.Consult a qualified water treatment specialist (i.e., onethat knows the local water supply chemical/mineralcontent) for a recommended cleaning solution suitablefor the job. (A standard condenser water circuit iscomposed solely of copper, cast iron and steel.)Improper chemical cleaning can damage tube walls.

All of the materials used in the external circulationsystem, the quantity of the solution, the duration of thecleaning period, and any required safety precautionsshould be approved by the company furnishing thematerials or performing the cleaning.

NNoottee:: Chemical tube cleaning should ALWAYS befollowed by mechanical tube cleaning.

Cleaning the EvaporatorBecause the evaporator is typically part of a closedcircuit, it does not accumulate appreciable amounts ofscale or sludge. However, if cleaning is deemednecessary, use the same cleaning methods describedin “Cleaning the Condenser,” p. 64.

Waterbox HingesThe hinged waterbox option is available for theevaporator, the condenser, or both. This option can beordered with the hinge only on the evaporator and/oronly on the condenser; however, the hinges MUST beordered for both ends of the evaporator and/or thecondenser.

The hinged waterbox option does NOT require annualmaintenance or lubrication, although a visualinspection is recommended to ensure that the hingeshave not been damaged or altered. For assembly anddisassembly of hinges, please refer to HDWA-SVN001*-EN.

IImmppoorrttaanntt:: Only use a vacuum for cleaning. DoNOT use compressed air.

5. Inspect the interior of the drive for any signs ofmoisture entry or leakage.

6. Visually inspect all drive components and wiring.Look for signs of heat or failure (look for swelled or

leaking capacitors, discolored reactors or inductors,broken pre-charge resistors, smoke or arc trails onMOVs and capacitors, etc.).

7. Closely inspect the motor terminal board for anysigns of leakage, arcing, etc..

8. Check ALL cable/lug/terminal connections insidethe drive enclosure. Ensure all are clean and tight,and not rubbing against each other anywhere.

9. Test pH levels annually. Replace fluid as necessary,or every 5 years.

10. Remove and clean electrical panel air filters.

Operational Inspection—Power Applied


1. Verify the drive cabinet cooling fans are operating.This should be done from outside the enclosure, bylooking into the cabinet at door and cabinet vents,to avoid electrical hazards.

NNoottee:: The power module fan comes on with power.Other fans cycle with drive operation.

2. Check historic fault codes using AdaptiveFrequency™ Drive (AFD) control panel (LCP).

NNoottee:: The AFD control panel is used ONLY forservice and should never be used formachine operation.

3. Check configuration settings and confirm all propersettings are still present in the controls.

4. Review the diagnostic history.

5. Make Chiller Service report to document allsetpoints.

6. Check the UC800 alarm histories for any indicationsof operational problems.
