Features/BenefitsComfortLink controlYour link to a world of simple and easy to use air-cooled chillers that offer out-standing performance and value. The 30GTN,GTR liquid chillers employ more than the latest advanced micro-processor controls, they utilize an expandable platform that grows as your needs change. From stand-alone opera-tion to remotely monitored and oper-ated multi-chiller plants, ComfortLink controls can keep you plugged in.
ComfortLink controls are fully com-municating, and are cable ready for connection to a Carrier Comfort Net-work (CCN). Occupancy scheduling, temperature and pressure read-outs, and the ComfortLink scrolling mar-quee clear language display compli-ment the standard features, linking you to a world of carefree comfort. The 30GTN,GTR chillers are built on the legendary performance of the Carrier model 30G Flotronic™ chiller and share many of the same time-proven features and technologies providing easy operation, quick installation and start-ups that save you money!
Superior temperature control equals potential for greater productivityWhether in the classroom, on the pro-duction floor, or in the office, ComfortLink controls can help you to adapt to changing weather and busi-ness conditions. Accurate temperature control provided by the Carrier Com-fortLink system helps to maintain higher levels of indoor air quality, ther-mal comfort, and productivity space.
While many air-cooled chillers use only leaving fluid temperature control, the 30GTN,GTR chillers utilize leaving fluid temperature control with a stan-dard entering fluid temperature com-pensation. This Carrier exclusive

provides smart control and intelligent machine capacity staging. Unlike many chillers, Carrier model 30GTN,GTR chillers do not require constant fluid flow. The ability to operate with vari-able flow also allows building owners to realize even greater overall system energy savings in the chilled water pumping system of up to 85%, and not just at the chiller.Energy management made easy While 30GTN,GTR chillers have many standard features such as network communications capability and temper-ature reset based on return fluid tem-perature, they can also expand as needs change. Supply temperature reset based on outside air or space temperature is as easy as adding a ther-mistor. The Energy Management option can allow you to take advantage of changing utility rate structures with easy to use load shedding, demand lim-iting and temperature reset capabilities. Reset triggered via 4 to 20 mA signal makes integrating from an existing building management system simple.
The ComfortLink™ platform can be expanded further with the Service Option which has all of the features of the Energy Management option, along with an additional hand-heldComfortLink Navigator™ display, remote service connection port, and GFCI convenience outlet (60 Hz only). While providing additional information in a clear language format, the Naviga-tor display can be plugged into the unit at either the control panel or at the remote service port, allowing the ser-vice technician to operate the unit from where the maintenance or service work is being performed, thereby minimizing downtime to ensure the system is ready for operation in the shortest amount of time. Both the Energy Management and Service Options can be factory-supplied or can be added in the field at a later date as needs change.Full and part load efficiency advantage The 30GTN,GTR chillers withComfortLink control offer outstanding efficiencies (EER [Energy Efficiency Ratio], COP [coefficient of perfor-mance], and IPLV [integrated part load value]) in both full (up to 9.96 EER)and part load operation (IPLVs up to 14.7). Increased part load efficiency is provided by dual independentrefrigeration circuits, suction cutoff unloading, and return fluid temperature compensation. All 30GTN,GTR chiller efficiencies are ASHRAE 90.1-1999 compliant.
The fully integrated ComfortLink control system maintains efficient con-trol over the compressors, unloaders, expansion valves, and condenser fans to optimize performance as conditions change. The Carrier exclusive long-stroke electronic expansion valve (EXV) operates at reduced condensing pressures, thereby allowing the control to operate the fans down to lower out-door temperatures. By utilizing valve position information, the control main-tains the highest possible evaporator pressure and minimizes the excessive superheat that conventional thermal expansion valve (TXV) systems require. Wider operating ranges equal increased efficiencies and lower installed costs.Building design flexibility Design and consulting engineers will appreciate the broad selection of sizes and wide operating range offered by the 30GTN,GTR chillers. With built-in dual chiller control, imaginative large tonnage systems can be easily engi-neered and controlled with smaller, easier to handle modules. Modular design allows engineers to consider side by side, offset, or angled place-ment to fit the awkward spaces that the architect sometimes leaves for mechan-ical systems. Or, in the case of planned expansion, additional cooling can be brought on-line and controlled from the same system.
In some places facility managers may find that the cash flow provided by building up large air-cooled multi-chiller plants can easily offset any efficiency losses when compared to large water- cooled centrifugal type chilled water plants. Quality and reliability To assure long life and quality perfor-mance, every chiller (both 50 and60 Hz) is factory run tested at full load. Individual components are also tested at many levels to assure that only the
best parts make it into 30GTN,GTR chillers. Long life and reliability are also a function of design. While some man-ufacturers like to talk about moving parts, Carrier’s engineers recognized the potential dangers to chiller systems caused by problems in the power distri-bution system. Low voltage and phase imbalances are but a few of the condi-tions that can hurt the compressor’s motor. Model 30G chillers were one of the first to offer ground current sensing to prevent compressor motor burn-out that would contaminate the system and potentially threaten the life of future replacement compressors. The 06E semi-hermetic compressors are built for performance and have proven themselves in commercial refrigeration equipment worldwide.
With tens of thousands of chillers operating in all corners of the world, end-users count on the reliability of Carrier 30G chillers. The Carrier McMinnville, Tennessee (U.S.A.) plant is an ISO 9001:2000 registered facility as are many of Carrier’s other compo-nent and assembly plants throughout the world.

Thermal expansion valves (TXV) (Sizes 060-110)and liquid line solenoid valves (LLSV) replace the EXV,related controls, and part-load energy savings related tothe EXV function. Minimum operating ambient tempera-ture for TXV-equipped units with standard head pressurecontrol is 35 F (1.7 C). Contact your Carrier representativefor details on operation at temperatures below 35 F(1.7 C).Hot gas bypass option allows additional capacity reduc-tion for unit operation below the minimum step of unload-ing. It is available on size 060 and 070 units. Also availableas a field-installed accessory.NOTE: Accessory unloaders (where available) furtherreduce minimum capacity step and provide a more effi-cient alternative to hot gas bypass in light load situations.Cooler heater helps protect the cooler to –20 F (–29 C).NOTE: For ambient temperatures below 32 F (0° C), inhib-ited glycol antifreeze solutions are recommended to pre-vent freeze-up in the event of power failure.Sound reduction option consists of specially designedsystem of fans and acoustic enclosures for reducing soundlevels without compromising chiller performance. For50 Hz units, this option uses low-noise AeroAcoustic (Fly-ing Bird) fans and taller discharge stacks. (Additional pack-aging is required. See Price Pages for further details.)Low-ambient Motormaster® V head-pressure con-trol allows unit operation to –20 F (–29 C) on all unit sizes.Also available as a field-installed accessory.Part-wind (PW) start generally is not required wheremultiple 06E compressors are installed. The starting cur-rent is usually lower than a larger compressor using PWstart. However, a part-wind start option is available(denoted by a R in the fifth position of the unit model num-ber) for all sizes.Brine option for all sizes permits leaving fluid tempera-tures to be set between 15 and 39 F (–9.4 and 3.9 C).Refrigeration circuit components, such as the expansiondevice, are modified to correct for the lower refrigerationflow rates and low-ambient Motormaster V control isrequired.Non-fused electrical disconnect is factory installed for allvoltages. For 060 and 070 sizes, disconnect is a “thru-the-door” type. For 080-110 and 230B-315B sizes, disconnectis a “thru-the-door” type except for 208/230-3-60 unitswhere the disconnect mounts below the control box. For130-210, 230A-420A, and 330B-420B sizes, disconnecton the center panel on the cooler side of the chiller.
High-static fans allow the 30GTN,GTR units to be used inapplications with an external static pressure of up to 1 in.wg (250 kPa) (external to the chiller) at nominal condenserairflow. Two options are available: 0.4 in. wg 100 kPa) and1 in. wg (250 kPa). These should be used to prevent areduction in airflow to the conditioned space whenever anapplication requires external ductwork which will raise thejob static requirements. Contact Carrier Application Engi-neering for more information.NOTE: Electrical requirements (MCA and MOCP) increasewith high-static fan option.Control transformer is sized to supply the needs of thecontrol circuit. Also available as a field-installed accessory.Energy Management Module (EMM) is used for 4 to20 mA leaving fluid temperature reset, cooling set pointreset, 4 to 20 mA demand limit and two-step demandlimit. Temperature reset lets the unit reset the leaving fluidtemperature to a higher temperature during low load con-ditions. Temperature reset can also be accomplished basedon return fluid, outdoor air or space temperature. (TheEMM option is not required when using entering-water,outdoor-air, or space temperature for temperature reset.These types of reset are available with the main board.However, an accessory thermistor is required for outdoorair and/or space temperature reset.) Demand limitingallows the unit capacity to be limited during periods ofpeak energy usage. Demand limit requires an external 4 to20 mA signal or a 2-step remote pair of dry contacts. Boththe 4 to 20 mA and 2-step demand limit percentage valuesare adjustable. This is also available as a field-installedaccessory.Service Option includes the Energy Management Mod-ule (described above) plus a GFCI (ground fault currentinterrupter) convenience outlet (60 Hz only), remote ser-vice connection port, and handheld ComfortLink™ Navi-gator™ display module. While providing additionalinformation in a clear language format, the Navigator dis-play can be plugged into the unit at either the control panelor at the remote service port, allowing the service techni-cian to operate the unit from where the maintenance orservice work is being performed, thereby minimizingdowntime to ensure the system is ready for operation inthe shortest amount of time.Condenser coil options (Enviro-Shield™) — Severaloptions are available to match coil construction to the siteconditions for the best durability. See page 47 for addi-tional details or contact your Carrier representative for fur-ther information.

Ground current protection includes an electronic sen-sor that monitors all phases of the 3-phase power supplyto the compressor. At the first sign of a short to ground,the sensor shuts down the compressor to prevent contami-nation of the refrigerant system. This protection is anaccessory for 060 and 070 (60 Hz) sizes only (standard on070 [50 Hz] and all 080-210 sizes [50/60 Hz]).Motormaster® V head-pressure control allows unitto operate down to –20 F (–29 C).
The accessory package includes sensor, control, andinstallation hardware. A Motormaster V control is requiredfor each circuit. For 60 Hz units, factory-installed fanmotors compatible with the Motormaster V control requireno motor change-out. The 50 Hz units require2 HD52AK653 or HD52AK654 speed control ratedmotors for each 060-210 module. In 575-v applications, 4transformers must be field-supplied. Also available as a fac-tory-installed option.Sound reduction kit consists of a specially-designed sys-tem of fans and acoustic enclosures for reducing sound lev-els without compromising chiller performance. No fanmotor change is required, and the fan system is compatiblewith Motormaster V head-pressure control. This accessoryis sold in sets of 2 kits per package.Security grilles protect the chiller cooler, compressorsand condenser coils from damage due to vandalism.Additional electric suction cutoff unloader(s) can befield-installed on all sizes. For installation on 060-110, 130(60 Hz), and 230B-315B sizes, the compressor expansionboard (CXB) accessory is required for operation of morethan 1 unloader per circuit. All other models have the CXBfactory installed. The following additional unloaders aresupported:
Unloader(s) (when available) further reduce minimumcapacity step and provide a more efficient alternative tohot gas bypass.Compressor expansion board is an additional circuitboard used in multiple compressor units. This accessorymay be required when installing additional unloaders.Discharge and suction pressure gage panel aids inroutine maintenance when reading system pressures. Bothpressure gages are mounted on a common panel. Eachgage is equipped with a shutoff valve. Each lead compres-sor requires a separate gage panel.Remote cooler mounting permits indoor relocation ofthe cooler up to 75 ft (22 m) away from base unit.Oil pressure switch package includes 2 oil pressureswitches for unit. The switch mounts on lead compressorin each refrigerant circuit. This is an accessory for 060 and070 sizes (standard on 080-210 sizes).

*Points A, B, C, and D are located in the corners of the unit. See pages 27-30 for dimensions.†Contact your local Carrier representative for more information on epoxy-coated and pre-
coated aluminum fins.NOTE: If spring isolators are used, a perimeter support channel between the unit and the isola-tors is recommended.
*Contact your local Carrier representative for more information on epoxy-coated and pre-coated aluminum fins.NOTES:1. Dimensions in ( ) are in millimeters.2. If spring isolators are used, a perimeter support channel between the unit and the isolators is recommended.
Leveling unitUnit must be level within 1/8-in. per ft when installed toensure proper oil return to the compressors.
While most outdoor locations are suitable for 30GTN,GTR units, the roof is a common site that presents a prob-lem if roof has been pitched to aid in water removal. Toassure proper oil return, be sure that unit is level, particu-larly in its major lengthwise dimension, as compressor oilreturn piping runs in that direction.
It should be determined prior to installation if any spe-cial treatment is required to assure a level installation.
Cooler fluid temperature1. Maximum leaving chilled fluid temperature (LCWT) for
unit is 70 F (21 C). Unit can start and pull down with upto 95 F (35 C) entering-fluid temperature due to MOP(maximum operating pressure) feature of the TXV. Forsustained operation, it is recommended that entering-fluid temperature not exceed 85 F (29.4 C).
2. Minimum LCWT for standard unit is 40 F (4.4 C). It ispermissible to use a standard microprocessor-controlledComfortLink™ chiller with leaving-fluid temperatures inthe range of 34 to 39.9 F (1.1° to 4.4 C) only if a pro-tective brine solution (20% antifreeze solution, orgreater) is used. (See Controls and Troubleshooting lit-erature for further information.)
Medium temperature brine applicationApplication of chiller for brine duty within the 39.9 to 15 F(4.4 to –9.4 C) range is possible by ordering the properfactory-installed brine option. For ratings below 40° F(4.4 C) LCWT, contact your local Carrier representative.
Leaving-fluid temperature resetThe Energy Management Module (EMM) is required for 4to 20 mA reset of LCWT in constant fluid systems. Resetby return fluid, outdoor-air temperature, or space tempera-ture does not require this option. Reset reduces compres-sor power usage at part load when design LCWT is notnecessary. Humidity control should be considered sincehigher coil temperatures resulting from reset will reducelatent heat capacity. Three reset options are offered, basedon the following:Return-fluid temperature — Increases LCWT tempera-ture set point as return (or entering) fluid temperaturedecreases (indicating load decrease). Option may be usedin any application where return fluid provides accurate loadindication. Limitation of return fluid reset is that LCWTmay only be reset to value of design return fluid tempera-ture.Outdoor-air temperature — Increases LCWT as out-door ambient temperature decreases (indicating loaddecrease). This reset should be applied only where outdoorambient temperature is an accurate indication of load. Anaccessory thermistor is required.Space temperature — Increases LCWT as space tem-perature decreases (indicating load decrease). This resetshould be applied only where space temperature is anaccurate indication of load. An accessory thermistor isrequired.
For details on applying a reset option, refer to unit Con-trols and Troubleshooting literature. Obtain ordering partnumbers for reset option from current price pages or con-tact your local Carrier representative.
Cooler flow rangeRatings and performance data in this publication are for acooling temperature rise of 10° F (5.6° C), and are suitablefor a range from 5 to 20 F (2.8 to 11.1 C) temperature risewithout adjustment. The ComfortLink chillers may beoperated using a different temperature range, providedflow limits are not exceeded. For minimum flow rates, seeMinimum Cooler Fluid Flow Rates and Minimum LoopVolume table. High flow rate is limited by pressure dropthat can be tolerated. If another temperature range is used,apply LCWT correction as given in Selection Procedureexample on page 52.

Minimum cooler flow (maximum cooler tempera-ture rise) — The minimum cooler flow for standard unitsis shown in Minimum Cooler Fluid Flow Rates and Mini-mum Loop Volume tables. When gpm (L/s) required islower (or rise higher), follow recommendations below:a. Multiple smaller chillers may be applied in series, each
providing a portion of the design temperature rise.b. Cooler fluid may be recirculated to raise flow rate. How-
ever, mixed temperature entering cooler must be main-tained a minimum of at least 5 F (2.8 C) above theLCWT.
c. Special cooler baffling is required to allow minimumflow rate to be reduced.
NOTE: Recirculation flow is shown below.
Maximum cooler flow — The maximum cooler flow(> 5 gpm/ton or < 5° F rise [> 0.09 L/s ⋅ kW or < 2.8° Crise]) results in practical maximum pressure drop throughcooler.1. Return fluid may bypass the cooler to keep pressure
drop through cooler within acceptable limits. This per-mits a higher ∆T with lower fluid flow through coolerand mixing after the cooler.
2. Special cooler baffling to permit a cooler flow rateincrease of 10% is available by special order.
NOTE: Bypass flow is shown below.
Variable cooler flow rates — Variable rates may beapplied to standard chiller. Unit will, however, attempt tomaintain a constant leaving chilled fluid temperature. Insuch cases, minimum flow must be in excess of minimumflow given in Minimum Cooler Fluid Flow Rates and Mini-mum Loop Volume table, and flow rate must change insteps of less than 10% per minute. Apply 6 gal. per ton(6.5 L per kW) water loop volume minimum if flow ratechanges more rapidly.
Fluid loop volume — The volume in circulation mustequal or exceed 3 gal. per nominal ton (3.25 L per kW) ofcooling for temperature stability and accuracy in normalair-conditioning applications. (For example, a 30GTN210would require 603 gal. [2232 L].) In process cooling appli-cations, or for operation at ambient temperature below32 F (0° C) with low loading conditions, there should befrom 6 to 10 gal. per ton (6.5 to 10.8 L per kW). Toachieve this volume, it is often necessary to install a tank inthe loop. Tank should be baffled to ensure there is no strat-ification and that water (or brine) entering tank is ade-quately mixed with liquid in the tank.NOTE: Tank installation is shown below.
Cooler fouling factor — The fouling factor used to cal-culate tabulated ratings was .00010 ft2 • hr • °F/ Btu(.000018 m2 • °C/W). As fouling factor is increased, unitcapacity decreases and compressor power increases.Standard ratings should be corrected using followingmultipliers:
Cooler protection — Protection against low ambientfreeze-up is required for unit operation in areas that experi-ence temperatures below 32 F (0° C). Protection should bein the form of inhibited glycol or other suitable brine.
Even though unit cooler is equipped with insulation andan electric heater that helps prevent freeze-up, it does notprotect fluid piping external to unit or if there is a powerfailure. Use only antifreeze solutions approved for heatexchanger duty. Use of automotive-type antifreezes is notrecommended because of the fouling that can occur oncetheir relatively short-lived inhibitor breaks down.
Draining cooler and outdoor piping is recommended ifsystem is not to be used during freezing weather condi-tions. See Low Ambient Temperature Operation sectionpage 45.
CondenserAltitude correction factors — Correction factors mustbe applied to standard ratings at altitudes above 2000 ft(610 m) using the following multipliers:
Condenser airflow — Airflow restrictions on units withstandard fans will affect the unit capacity, condenser headpressure, and compressor power input. Correction factorsto be applied for external static restrictions up to 0.2 in. wg(50 Pa) are as follows:
High ambient temperatureHigh outdoor ambient chiller start-up and operation (fullyloaded) is possible for standard 30GTN,GTR chillers atambient temperatures up to 125 F (52 C) at nominal volt-age. In some cases, where return water temperature isexpected to exceed 60 F (15.5 C), an accessory kit may berequired.
Low ambient temperature operationWith certain field provisions as described below, units willstart and operate down to:
0° F (–18 C) for EXV units35° F (1.7 C) for 30GTN,GTR060-110 TXV unitsIf operation is intended below these limits, the Carrier
accessory Motormaster® V condenser head pressure con-trol and its associated components must be added. TheMotormaster control allows operation down to –20 F(–29 C). Consult your Carrier representative for details.NOTE: Minimum load on chiller must be above minimumstep of unloading.Wind baffles (field fabricated and installed) — Baf-fles must be added to all units for operation below 32 F(0° C) if wind velocity is anticipated to be greater than5 mph (8 km/h).Antifreeze solution — Inhibited ethylene glycol or othersuitable corrosion-resistant anti-freeze solution must befield supplied and installed in all units for unit operationbelow 32 F (0° C). Solution must be added to fluid loop toprotect loop down to 15° F (8° C) below minimum operat-ing ambient temperature. Concentration should be basedon expected minimum temperature and either “Burst” or“Freeze” protection levels.
Provide sufficient volume in the chilled fluid loop —At least 6 gal per ton (6.5 L per kW) of refrigeration is therecommended minimum for a moderate system load.Freeze versus burst protection — If chiller operation isnot required during winter/off season, lower glycol con-centrations based on “burst” protection criteria may be
considered. Often use of burst protection results in lowerfluid costs and has less impact on chiller cooler capacityand flow rate. Consult glycol fluid manufacturers for burstprotection recommendations and fluid specifications.
Capacity correction (antifreeze)Inhibited ethylene glycol (or other suitable brine) shouldbe used in installations where subfreezing temperaturesare expected. Unit performance data must be correctedfor the addition of inhibited ethylene glycol as shown in fol-lowing example. Correction factors can be derived fromcurves in the Inhibited Ethylene Glycol Performance chartat right. Additional performance information on this andother fluids is available in Carrier’s Electronic Catalog(E-CAT) software program. “Slush” and “Burst” concentra-tion may also be considered for winter shutdown protec-tion and when unit operation is not required.Example: English — Where a 5 F outdoor temperatureis anticipated, determine concentration of inhibited ethyl-ene glycol to protect system to –10 F ambient temperatureat zero flow.
Enter the solution crystallization point curve (at right) at–10 F; read that 40% concentration of inhibited ethylenegly-col is required to prevent crystals from forming insolution.
Consider the 30GTN110 unit from the Selection Proce-dure example on page 52 (refer to correction curves at40% solution).Correct unit capacity — On the capacity correction curvein chart on page 46, read 0.95.Corrected capacity = 0.95 x determined capacity
= 0.95 x 111.4= 105.8 tons
Correct cooler water flow — On the cooler flow correc-tion curve on page 46, read 1.15.Chilled water flow (at corrected capacity)
Chilled water flow (40% solution)= 1.15 x 181.4= 208.6 U.S. gpm
Correct cooler pressure drop — On cooler pressure dropcorrection curve on page 46, read 1.33.
On cooler pressure drop curve on page 48, for208.6 gpm, read pressure drop = 8.1 ft water gage. Thepressure drop for 40% solution = 1.33 x 8.1 = 10.8 ftwater.Correct compressor power input (kW) — On power cor-rection curve below, read 0.97 correction factor at 40%ethylene glycol concentration.
Power input from Selection Procedure example =125.4 kW.Corrected power input = 0.97 x 125.4 = 121.6 kW
= 24 x corrected cap. in tons = U.S. gpmtemperature rise F

Example: SI — Determine concentration of inhibited eth-ylene glycol to protect the system to –23 C ambient tem-perature at zero flow.
Enter the solution crystallization point curve above, at–23 C, read 40% concentration inhibited ethylene glycol isrequired to prevent crystals from forming in solution.
Consider 30GTN110 unit selected from the SelectionProcedure example (refer to correction curves at 40%solution).Correct unit capacity — On glycol performance capacitycorrection curve above, read 0.95.Corrected capacity = 0.95 x determined capacity
= 0.95 x 375.4= 356.6 kW
Correct chilled water flow — On cooler flow correctioncurve above, read 1.15.
Chilled water flow (at corrected capacity)
Chilled water flow (40% solution)= 1.15 x 10.9= 12.5 L/s
Correct cooler pressure drop — On cooler pressure dropcorrection curve on this page, read 1.33.
On cooler pressure drop curve on page 48, for12.8 L/s, read pressure drop of 24 kPa. The pressuredrop for 40% solution = 1.33 x 24 = 31.92 kPa.Correct compressor power input (kW) — On the powercorrection curve on this page, read 0.97 correction factorat 40% ethylene glycol concentration.
Power input from Selection Procedure example =122.4 kW.
Corrected power input = 0.97 x 122.4 = 118.7 kW.
Oversizing chillersOversizing chillers by more than 15% at design conditionsmust be avoided as the system operating efficiency isadversely affected (resulting in greater or excessive electri-cal demand). When future expansion of equipment is antic-ipated, install a single chiller to meet present loadrequirements and add a second chiller to meet the addi-tional load demand.
It is also recommended that 2 smaller chillers be installedwhere operation at minimum load is critical. The operationof a smaller chiller loaded to a greater percentage overminimum is preferred to operating a single chiller at ornear its minimum recommended value.
Hot gas bypass should not be used as a means to allowoversizing chillers. Hot gas bypass should be given consid-eration where substantial operating time is anticipatedbelow the minimum unloading step.
Multiple chillersWhere chiller capacities greater than 210 tons (740 kW)are required, or where stand-by capability is desired, chill-ers may be installed in parallel. Units should be of equalsize to ensure balanced fluid flows. Where a large tempera-ture drop (> 25° F [13.9° C]) is desired, chillers may beinstalled in series. Fluid temperature sensors need not bemoved for multiple chiller operation. A 10 ft (3 m) separa-tion is required between units for airflow, and a 6 ft (1.8 m)distance is required from units to obstructions. See MultipleUnit Separation figure below. See Base Unit Dimensionssection on pages 27-38 for service clearances.
Unit software is capable of controlling two units as a sin-gle plant. Refer to Controls, Start-Up, Operation, Service,and Troubleshooting guide for further details.

Electrical/utility interestsEnergy management — Use of energy managementpractices can significantly reduce operating costs, espe-cially during off-peak modes of operation. Demand limitingand temperature reset are 2 techniques for accomplishingefficient energy management. See Demand Limiting (alsocalled load shedding) section below and Leaving-Fluid Tem-perature Reset section on page 43 for further details.Demand limiting (also called load shedding) —When a utility’s demand for electricity exceeds a certainlevel, loads are shed to keep electricity demand below aprescribed maximum level. Typically, this happens on hotdays when air conditioning is most needed. The EnergyManagement Module (EMM) can be added to accomplishthis reduction.
Demand may be limited on unit by resetting fluid tem-perature, or by unloading the chiller to a given predeter-mined percentage of the load. Demand limit may also bedriven by an external 4 to 20 mA signal. These featuresrequire a signal from an intelligent central control. Do notcycle demand limiter for less than 10 minutes on and5 minutes off.
Duty cycling cycles electrical loads at regular intervalsregardless of need. This reduces the electrical operatingcosts of building by “fooling” demand indicating devices.Duty cycling of compressors or fans is not recommendedsince motor winding and bearing life suffer from constantcycling.
Remote on-off controlRemote on-off control may be applied by hard-wired con-nection (see Controls and Troubleshooting literature) or byconnection to a Carrier Comfort Network (CCN).
Part-wind startThis is not generally required on 30GTN,GTR chillers dueto use of multiple compressors allowing smaller electricalload increments, but is available if required. Maximuminstantaneous current flow (see ICF in Electrical Data tableon pages 77-79) should be used in determining need.
StrainersIt is recommended that a strainer with a minimum of20 mesh be installed in the cooler fluid inlet line, just aheadof and as close as possible to the cooler.
Condenser coil protection (Enviro-Shield™)Pre-coated aluminum-fin coils have a durable epoxy-phenolic coating applied to the fin prior to the fin stampingprocess to provide protection in mildly corrosive coastalenvironments. Pre-coated coils have an inert barrierbetween the aluminum fin and copper tube. This barrierelectrically disconnects the dissimilar metals to minimizethe potential for galvanic corrosion. This economicaloption provides substantial corrosion protection beyondthe standard uncoated coil construction.Copper-fin coils provide increased corrosion resistancein moderate coastal environments where industrial air pol-lution is not present. All copper coils eliminate bi-metallicconstruction to eliminate the potential for galvanic corro-sion. Application in industrial environments is not recom-mended due to potential attack from sulfur, sulfur oxide,nitrogen oxides, carbon and several other industrial air-borne contaminants. In moderate seacoast environments,copper-fin coils have extended life compared to standardor pre-coated aluminum-fin coils.E-coated aluminum-fin coils have an extremely flexibleand durable epoxy coating uniformly applied to all coil sur-faces. Unlike brittle phenolic dip and bake coatings, E-coatprovides superior protection with unmatched flexibility,edge coverage, metal adhesion, thermal performance andmost importantly, corrosion resistance. E-coated coils pro-vide this protection since all coil surfaces are completelyencapsulated from environmental contamination. SpecifyE-coated aluminum-fin coils for industrial environmentswith high levels of air pollution. This option also providesbetter protection compared to standard or pre-coated alu-minum-fin coils in industrial environments.E-coated copper-fin coils have the same flexible anddurable epoxy coating as E-coated aluminum-fin coils.However, this option combines the natural salt and envi-ronmental resistance of all-copper construction with thehighest level of corrosion protection. Specify E-coated cop-per-fin coils in the harshest combination of coastal andindustrial environments.

The microprocessor routine is started by switching theEmergency ON-OFF circuit breaker switch (switch 2) to theON position.
When the unit receives a call for cooling (either from theinternal control or CCN network command), the unitstages up in capacity to maintain the cooler fluid set point.The first compressor starts 11/2 to 3 minutes after the callfor cooling. The lead circuit can be specifically designatedor randomly selected by the controls, depending on howthe unit is field configured. A field configuration is alsoavailable to determine if the unit should stage up both cir-cuits equally or load one circuit completely before bringingon the other.
The ComfortLink microprocessor controls the capacityof the chiller by cycling compressors on and off at a rate tosatisfy actual dynamic load conditions. The control main-tains leaving-fluid temperature set point shown on scrollingmarquee display board through intelligent cycling of com-pressors. Accuracy depends on loop volume, loop flowrate, load, outdoor-air temperature, number of stages, andparticular stage being cycled off. No adjustment for coolingrange or cooler flow rate is required, because the controlautomatically compensates for cooling range by measuringboth return-fluid temperature and leaving-fluid tempera-ture. This is referred to as leaving-fluid temperature con-trol with return-fluid temperature compensation.
The basic logic for determining when to add or remove astage is a time band integration of deviation from set pointplus rate of change of leaving-fluid temperature. Whenleaving-fluid temperature is close to set point and slowlymoving closer, logic prevents addition of another stage. Ifleaving-fluid temperature is less than 34 F (1.1 C) forwater, or 6° F (3.3° C) below the set point for brine units,the unit is shut off until the fluid temperature goes to 34 F(1.1 C) or to 6° F (3.3° C) above the set point to protectagainst freezing.
If 1° F per minute (0.6° C per minute) pulldown controlhas been selected (factory setting), no additional steps ofcapacity are added as long as difference between leaving-fluid temperature and set point is greater than 4° F (2.2° C)and rate of change in leaving-fluid temperature is less than1° F per minute (0.6° C per minute).
If it has been less than 90 seconds since the last capacitychange, compressors will continue to run unless a safetydevice trips. This prevents rapid cycling and also helpsreturn oil during short on periods.
Lead/lag operation can be configured to balance com-pressor operating hours when set to automatic. Whenlead/lag operation is configured to automatic, a compres-sor wear factor is used to determine which circuit to startfirst by utilizing a combination of actual run hours also be
started to maintain even wear factors. Either circuit can beset to always lead, if desired.
The control also performs other special functions whenturning on or off. When a circuit is to be turned off, EXVor LLSV (TXV units) is closed first, and compressor is rununtil conditions are met to terminate pumpout to removerefrigerant that was in the cooler. At start-up, if a circuithas not run in the last 15 minutes, circuit is run to removeany refrigerant that has migrated to the cooler. The oilpressure switch is bypassed for 2 minutes during start-upand for 1 minute during normal operation.
ThermistorsEight thermistors are used for temperature-sensing inputsto microprocessor. (A ninth [T9] and/or tenth [T10] maybe used as a remote temperature sensor for optionalLCWT reset.)
T1 Cooler leaving chilled fluid temperatureT2 Cooler entering fluid (return) temperatureT3 Saturated condensing temperature — Circuit AT4 Saturated condensing temperature — Circuit BT5 Cooler saturation temperature — Circuit AT6 Cooler saturation temperature — Circuit BT7 Return gas temperature entering compressor
cylinder — Circuit AT8 Return gas temperature entering compressor
cylinder — Circuit BT9 Outdoor air temperature sensor (accessory)T10 Remote space temperature sensor (accessory)The microprocessor uses these temperatures to control
capacity, fan cycling, and EXV operation.
Electronic expansion valve (EXV)To control flow of refrigerant for different operating condi-tions, EXV piston moves up and down over slot orificesthrough which refrigerant flows to modulate size ofopening. Piston is moved by a stepper motor through15,000 discrete steps. The piston is repositioned by themicroprocessor every 3 seconds as required.
The EXV is used to control superheat in compressor.The difference between 2 thermistors (compressor returngas temperature minus cooler saturation temperature) isused to determine superheat. The EXV is controlled tomaintain superheat entering pistons at approximately 29 F(16.1 C), which results in slightly superheated refrigerantleaving cooler.
The electronic control provides for a prepurge and pum-pout cycle each time the lead compressor in a circuit isstarted or stopped. These pumpout cycles minimizeamount of excess refrigerant that can go to compressor onstart-up and cause oil dilution (which would result in even-tual bearing wear).
The microprocessor software is programmed so thatEXV functions as an MOP (maximum operating pressure)valve, limiting the suction temperatures to 55 F (12.8 C).This makes it possible to start unit at high fluid tempera-tures, up to 95 F (35 C), without overloading compressor.Another feature that is factory set (can be reconfigured inthe field) limits rate of pulldown to 1° F (0.6° C) perminute, thereby reducing the kW demand on start-up.

Thermal expansion valve (TXV, 060-110 sizes only)If installed, the TXV also controls refrigerant flow to thecooler for different operating conditions. An equalizationline and temperature controlled sensing bulb are used tomaintain a fixed setting of superheated refrigerant leavingthe cooler.
Accessory controlsDemand can be further limited by keeping a selected num-ber of compressors from turning on by utilizing demandlimit control (the Energy Management Module is requiredfor this function). This FIOP/accessory interfaces withmicroprocessor to control unit so that chiller’s kW demanddoes not exceed its setting. It is activated from an externalswitch.
The standard ComfortLink™ control is programmed toaccept various accessory temperature reset options (basedon return-fluid temperature, outdoor-air temperature, orspace temperature), that reset the LCWT. An accessorythermistor (T9 or T10) is required if outdoor-air tempera-ture or space temperature reset is selected. The EnergyManagement Module (EMM) is only required for tempera-ture reset that is initiated by a 4 to 20 mA signal.
Ground current protectionThe 080-210 and 070 (50 Hz) sizes have ground currentprotection that shuts off compressor(s) if a 2 to 3 ampground current is sensed by a toroid around the compres-sor power leads.
Ground current protection is also offered as accessoryon 060 and 070 (60 Hz) sizes.
30GTN,GTR ComfortLink controls with Scrolling Marquee display moduleA standard four-digit alphanumeric display shows all of theComfortLink control codes (with expandable clear lan-guage), plus set points, time of day, temperatures, pres-sures, and superheat. Additional information can bedisplayed all at once with the Navigator display.
Control sequenceOff cycle — During unit off cycle, crankcase heater isenergized. If ambient temperature is below 36 F (2 C),cooler heaters (if equipped) are also energized. Electronicexpansion valves are closed.Start-up — After control circuit switches on, prestart pro-cess takes place, then microprocessor checks itself andwaits for temperature to stabilize. First circuit to start maybe A or B (automatic lead/lag feature). The controlled pull-down feature limits compressor loading on start-up toreduce demand on start-up and unnecessary compressorusage. The microprocessor limits supply-fluid temperaturedecrease (start-up only) to 1° F (0.6° C) per minute.
Capacity controlOn first call for cooling, microprocessor starts initial com-pressor and fan stage on lead circuit. The EXV or LLSV(TXV units) remains closed, permitting a pumpout on star-tup. After pumpout, the valves open and, if necessary,additional outdoor fans are energized. Crankcase heaters
are deenergized when a compressor is started. As addi-tional cooling is required, lag circuit starts. If further coolingis needed, compressors are added, alternating betweenlead and lag circuits. Speed at which capacity is added ordecreased is controlled by temperature deviation from setpoint and rate of temperature change of chilled fluid.
As less cooling is required, circuits shut down (or unload)in an order that balances each circuit’s compressor runtime (depending upon configuration). When no furthercooling is called for (in each compressor circuit), EXV orLLSV (TXV units) closes and compressor and fans con-tinue to run while pumping down cooler.
Control featuresLow-temperature override — This feature preventsLCWT from overshooting the set point and possibly caus-ing a nuisance trip-out by the freeze protection.High-temperature override — This feature allowschiller to add capacity quickly during rapid load variations.Demand limit — If applied, limits the total power draw ofunit to selected point by controlling number of operationalcompressors during periods of peak electrical demand.The Energy Management Module is required for either2-stage or 4 to 20 mA demand limit.Temperature reset — If applied, microprocessor com-pares either return fluid, space temperature, or outdoor-airtemperature with the accessory board settings, and adjustsLCWT appropriately. The Energy Management Modulecan also be added for 4 to 20 mA reset.Electronic expansion valve and condenser-fan con-trol — The EXV opens and closes on signal from micro-processor to maintain an approximate 29° F (16° C)refrigerant superheat entering the compressor cylinders.(The compressor motor increases the refrigerant superheatfrom the approximate 5° F [3° C] leaving the cooler to thatentering the cylinders.) Condenser fans (operated bymicroprocessor) run to as low an ambient as possible tomaintain a minimum EXV pressure differential.
Abnormal conditionsAll control safeties in chiller operate through compressorprotection board or control relay and microprocessor.High-pressure switch directly shuts down compressor(s)through compressor protection board or control relay. Forother safeties, microprocessor makes appropriate decisionto shut down a compressor due to a safety trip or bad sen-sor reading and displays appropriate failure code on thedisplay. Chiller holds in safety mode until reset. It thenreverts to normal control when unit is reset.Oil pressure safety — Safety cuts out if pressure differ-ential is below minimum (accessory on sizes 060, 070).Safety is bypassed on start-up for 2 minutes.Loss-of-charge safety — Safety cuts out if system pres-sure drops below minimum.High-pressure cutout — Switch shuts down com-pressors if compressor discharge pressure increases to426 psig (2918 kPa).
Controls (cont)

Ground current safety — Safety opens on sensinga current-to-ground in compressor windings in excess of2.5 amps (accessory on sizes 060 and 070 [60 Hz]).Compressor anti-cycling — This feature limits com-pressor cycling.Loss of flow protection — Additional protection is pro-vided by temperature differences between entering andleaving fluid temperature sensors if cooler temperaturedrops to 34 F (1.1 C). Proof of flow switches arerecommended.Sensor failures — Failures are detected by themicroprocessor.
DiagnosticsMicroprocessor may be put through service test (see Con-trols, Start-Up, Operation, Service and Troubleshooting lit-erature) without additional equipment or tools. Service testconfirms microprocessor is functional, informs observerthrough display the condition of each sensor and switch inchiller, and allows observer to check for proper operationof fans and compressor(s).
Default settingsTo facilitate quick start-ups, all 30GTN,GTR chillers withComfortLink™ controls are pre-configured with a defaultsetting that assumes stand-alone operation supplying 44 F(6.7 C) chilled water.
Configuration setting will be based on any options oraccessories included with the unit at the time of manufac-turing. Date and time are set to U.S.A. central time zoneand will need reconfiguring based on location and localtime zone. If operation based on occupancy scheduling isdesired, this will also need to be set during installation.
