Cabinet
All unit frames are constructedof heavy gauge steel channel and painted with a corrosion resistantpolyester powder coat paint. The sheet metal cabinets are constructedof heavy gauge galvanized sheet steel painted with polyester powdercoat paint rated at more than a 1,000hours salt spray rating. The frameincludes fork truck access pockets in two dimensions and lifting points for easy maneuvering during installation andservicing.
Compressors
Scroll chillers use high efficiency R-410A, hermetically sealed, scroll compressors that are mounted on rubber grommets for vibration isolation. Scroll compressorsprovide high efficiency while providing greater tolerance to liquid refrigerant entering the suction port.
Water-to-Refrigerant Heat ExchangerLarge oversized stainless steel interlaced dual circuit copper-brazed plate water-to-refrigerant heat exchangers provide unparalleled efficiency. The heat exchangershave a common water circuit with isolateddual refrigerant circuits so that in part load operation, the full mass of the heatexchanger is utilized. All heat exchangers are pressure rated to 450 psi water side and650 psi refrigerant side. All heat exchangers,water lines, and suction lines are insulatedto prevent condensation during low temperature inlet water operation.
Thermostatic and Electronic Expansion Valves
All chillers utilize bi-directional balanced port thermostatic expansion valves (TXV’s) for refrigerant metering. These valves feature stainless steel capillary tube and bulb for structural reliability over traditional copper tubes and sensing bulbs. The valve consists of a laser welded power head, forged brass valve body and a diaphragm optimized for R-410A refrigerant applications. The valve design allows precision refrigerant flow over a wide range of operating fluid temperatures.
Inside the Modular Scroll Chiller SeriesAn optional electronic expansion valve (EEV) may be utilizedon select product. EEV’s allow improved efficiency through precision metering and are controlled by a sophisticated and field proven EEV control algorithm onboard the HydroLink Aurora control board.
Strainers (Accessory)All chillers shall have a field-installedaccessory strainer either Y-type or basket type. Strainers are made of a suitable body such as brass with 316stainless steel screens with a minimum
of 30 mesh.
Flow SwitchAll chillers come standard with a flowswitch, which prevents the unit from startingunder a no-flow or low flow condition. Theflow switches are monitored by the AuroraHydrolink controller, and status can bereported to the BAS
Isolation ValvesAll chillers have a motorized isolation valve and a manual isolation valve on each heat exchanger. The motorizedisolation valve is controlled by theunit’s Aurora Hydrolink controller, and is provided to isolate the unit fromflow when not in service to minimizepumping requirements. The manualand auto isolation valves can be shutin the event the unit needs to beseparated from the optional pipe rack.
Compressor Protection ModuleSome chillers come with external compressor protection module that provides additional motor protection such as
reverse phase detection and a pre-wire thermistor.
Reversing Valve
Reversible units feature a reliable
all-brass pilot operated refrigerant
reversing valve. The reversing valve
operation is limited to change of
mode by the control to enhance reli-
ability. The reversing valve operates
when heating the load and defaults
to cooling mode.

Optional Header Pipe Rackp pAdding the patented WaterFurnace Header Pipe Rack allows several internal manifolded loop options. The header rack
is factory mounted to the modular chiller or it can be shipped separately for ease of plumbing the mechanical room.
Additional header racks can be installed independent of the chiller to allow for future expansion of the central plant
capacity.
4 Pipe Standard
4 Pipe Standard is the simplest header pipe rack option providing chilled water to the cold loop and hot water to the hot or
geo loop depending on the application. This header rack option is available on standard and reversing refrigerant chillers.
When used on reversing refrigerant chillers, this option can be used as a seasonal switchover of hot and cold loops.
4 Pipe Reversing
4 Pipe Reversing header rack option adds the capability of switching the load and source heat exchangers of a standard
chiller to add hot and cold water generation capability using 3-way valves. This options provides the advantage of optimal
flow configuration through each heat exchanger for either heating or cooling mode.

13
WC MODULAR SCROLL CHILLER SPECIFICATION CATALOG
6 Pipe Dedicated
6 Pipe Dedicated is similar to a 4 pipe reversing with an additional set of pipes that can be connected to a dedicate source
or geo loop on reversing refrigerant chiller. The advantage to this header rack option is the ability to have a different brine
solution in the dedicated loop while providing hot or chilled water on the load side heat exchanger. A set of 3-way valves
control the load heat exchanger to either provide hot water to hot loop or chilled water to the cold loop.
6 Pipe Standard
6 Pipe Standard allows a standard chiller to provide hot and chilled water simultaneously by controlling 3-way valves.
There are seven different control modes of operation available with this configuration that are detailed on the next page.

Header Pipe Rack: Operating Modesp p g
Header Pipe Rack: Operating ModesThe HydroLink Aurora Control includes the Header Pipe Rack operating logic and operating modes for each chiller
which are selectable through the chiller touchscreen tablet mounted on the high voltage door.
The Header Pipe Rack operating modes are detailed as follows:
1 – Cooling Only – Operation is based on the cold water set point and control temperature. The cold water loop is
connected to the load heat exchanger while the source heat exchanger is connected to the geo loop.
1 – Heating Only – Operation is based on the hot water set point and control temperature. The hot water loop is
connected to the source heat exchanger while the load heat exchanger is connected to the geo loop.
3 – Auto Full Building – The auto full building mode is only available with the 6 Pipe Standard configuration. Auto
full building mode will only activate with simultaneous heating and cooling demands similar to Full Building mode
that is described below. After activating, the chiller will operate in Full Building mode until either the hot or cold
water temperature reaches its set point. If the hot water temperature reaches set point first, then the system will
operate in Primary Cooling mode which is described below. If the cold water temperature reaches set point first,
then the chiller will operate in Primary Heating mode. When the chiller is operating in Auto Full Building mode,
it will control compressor capacity to the larger of the heating or cooling demand prior to switching into Primary
Cooling or Primary Heating mode.
4 – Full Building Mode – In Full Building mode, the hot water loop is connected to the source heat exchanger while
the cold water loop is connected to the load heat exchanger. In this mode, the chiller activates when the cold water
temperature is above the cold water set point and the hot water temperature is below the hot water set point. This
mode will de-activate when either of the one of these temperatures crosses the set point. Compressor capacity in
Full Build mode is control by the smaller of the heating or cooling demand. Full Building mode is not available with
6 Pipe Dedicated option.
5 – Primary Cooling – Primary Cooling is only available on 6 Pipe Standard configuration. This mode will activate
and de-activate based upon the cooling demand only while modulating the source 3-way valves between 50% and
100% to maintain hot water temperature.
6 – Primary Heating –Primary Heating is only available on 6 Pipe Standard configuration. This mode will activate
and de-activate based upon the heating demand only while modulating the load 3-way valves between 50% and
100% to maintain cold water temperature
99 – System Off – The System Off mode disables all Header Pipe Rack logic and outputs. In this mode it will oper-
ate as if there is not a header rack connected to the system.

HydroLink Aurora Chiller Controlsy
OverviewThe HydroLink Aurora Control is the ultimate chiller control
system that accurately controls fluid temperatures while
providing technical information about the system in a
simple, readable format thru a large 10” touchscreen tablet.
The backbone of the system is the field proven Aurora
compressor management control system. The Aurora Controls
communicate using the ModBus protocols and quickly pass
information from sensors up to the HydroLink controller. The
HydroLink controller in turn is a powerful controller that does
compressor staging and then communicates over the network
via BACnet, LonWorks, or thru the NiagaraAX platform.
This system is the best combination of a proven, robust
compressor management control coupled with a flexible yet
powerful system level controller. High end, graphic browser
images are hosted on the HydroLink controller and displayed
on the factory mounted touchscreen tablet. Each chiller is
equipped with a small Wi-Fi router or a hardwire Ethernet
connection that offers additional connectivity options to
display chiller information without tapping in the BAS network.
There are several factory installed components so that each
chiller has built-in refrigeration, energy, and performance
monitoring capabilities.
HydroLink Control
The HydroLink Control is a NiagaraAX control that functions
as a master control communicating to ABC “A” for compressor
A and to ABC “B” for compressor B via Modbus protocol. The
HydroLink controls all higher functions as a master control
managing lead/lag, user interface and other functions of each
ABC/AXB combination by communicating via Modbus. The
HydroLink also manages all BAS and 10” color touchscreen
tablet communications.
Aurora ‘Base’ Control (ABC)
The Base Control functions as a microprocessor compressor
monitoring device and handles all compressor timings, and
control. One board is dedicated to each compressor and is
labeled for circuit A and B.
Aurora Expansion Board (AXB)
The AXB functions as an I/O expander for the ABC Most
of the Circuit A I/O is for the compressor circuit however
some additional sensors also function with the Source
heat exchanger. The B Circuit AXB in turn handles circuit
B compressor plus some I/O dedicated to the Load heat
exchanger.
NOTE: Refer to the Aurora Base Control Application and
Troubleshooting Guide and the Instruction Guide: Aurora
Interface and Diagnostics (AID) Tool for additional information.

Field Selectable Options via Hardware DIP Switch (SW1) – Test/Configuration Button (See SW1Operation Table)
Test Mode
The control is placed in the test mode by holding the push
button switch SW1 for 2 - 5 seconds. In test mode most of
the control timings will be shortened by a factor of sixteen
(16). LED3 (green) will flash at 1 second on and 1 second off.
Additionally, when entering test mode LED1 (red) will flash
the last lockout one time. Test mode will automatically time
out after 30 minutes. Test mode can be exited by press-
ing and holding the SW1 button for 2 to 5 seconds or by
cycling the power. NOTE: Test mode will automatically be
exited after 30 minutes.
Reset Configuration Mode
The control is placed in reset configuration mode by holding
the push button switch SW1 for 50 to 60 seconds. This will
reset all configuration settings and the EEPROM back to
the factory default settings. LED3 (green) will turn off when
entering reset configuration mode. Once LED3 (green) turns
off, release SW1 and the control will reset.

Safety Features
The following safety features are provided to protect the
compressor, heat exchangers, wiring and other components
from damage caused by operation outside of design
conditions.
Fuse – a 3 amp automotive type plug-in fuse and each ABC
provides protection against a low Voltage short circuit or
overload conditions.
Lead/Lag Operation - The lead/lag circuit will switch
between circuit A and B at every start up to even run time
between circuits. Therefore Stage 1 can energize Circuit A or B
depending upon the state of the lead/lag circuit.
Anti-Short Cycle Protection – 5 minute anti-short cycle
protection for the compressor.
Compressor Minimum On Time - 5 minute minimum on-time
protection for the compressor to insure oil circulation for each
compressor cycle.
Random Start – 5 to 80 second random start upon power up
and return from load shed or emergency shutdown.
Fault Retry – in the fault condition, the control will stage off
the outputs and then “try again” to satisfy the Y input call.
Once the thermostat input calls are satisfied, the control will
continue on as if no fault occurred. If 3 consecutive faults
occur without satisfying the thermostat Y input call, then the
control will go to lockout mode.
Lockout – when locked out, the Alarm output (ALM)and Lockout output (L) will be turned on. The fault typeidentification display LED1 (Red) shall flash the fault code. Lockout may also be reset by turning power off for at least 30 seconds or through HMI, BACnet, or Lon.
High Pressure – The E2 fault is recognized when the Normally
Closed High Pressure Switch, P4-9/10 opens, no matter how
momentarily. The High Pressure Switch is electrically in series
with the Compressor Contactor and serves as a hardwired
limit switch if an overpressure condition should occur.
Low Pressure OR Loss of Charge - The E3 fault is recognized
when the Normally Closed Low Pressure Switch, P4-7/8 is
continuously open for 30 seconds. Closure of the LPS any time
during the 30 second recognition time restarts the 30 second
continuous open requirement.
In a Loss of Charge, the E3 fault is recognized when the
Normally Closed Low Pressure Switch, P4-7/8 is open prior to
the compressor starting.
19
WC MODULAR SCROLL CHILLER SPECIFICATION CATALOG
Freeze Detection - Refrigerant (Source – E5 or LoadHX E4) – Freeze detection can be triggered by either a
30 sec. recognition of the FP1 (Source HX) or FP2 (Load
HX) temperature OR a 30 sec recognition of saturation
temperature (using Suction pressure) below setpoint of 30
degrees. For the FP sensors, set points shall be either 30°F
[-1.1 °C] or 15°F [-9.4°C] for the refrigerant temperature (can
also be adjusted between these points). When the thermistor
temperature drops below the selected set point, the control
shall begin counting down the 30 seconds delay. If the
thermistor value rises above the selected set point, then the
count should reset. The resistance value must remain below
the selected set point for the entire length of the appropriate
delay to be recognized as a fault.
For the Saturation Temperature, the suction pressure sensor
is monitored and when the resulting saturation temperature
is below 30°F [-1.1°C] for 30 continuous seconds a fault is
triggered in a similar fashion. There is no indication which
condition has triggered the fault other than sensor readings at
the time of the event.
Water Temp Fault EST/ELT – HX fluid (Source or Load HX) –An E26 alarm can be triggered by a 30 sec. recognition of the
EST (Source or Load HX) temperature below specified limit.
An E27 alarm can be triggered by a 30 sec. recognition of the
EST (Source or Load HX) temperature above specified limit.
It is recommended that the Alarms be set 1-2 degrees off of
the Fault set points so that the Alarm will trigger first prior to
generating the faults or Lockouts.
Water Temp Fault LST/LLT – HX fluid (Source or Load HX) –An E28 alarm can be triggered by a 30 sec. recognition of the
EST (Source or Load HX) temperature below specified limit.
An E29 alarm can be triggered by a 30 sec. recognition of the
EST (Source or Load HX) temperature above specified limit.
It is recommended that the Alarms be set 1-2 degrees off of
the Fault set points so that the Alarm will trigger first prior to
generating the faults or Lockouts.
Over/Under Voltage Shutdown - An over/under voltage
condition exists when the control voltage is outside the range
of 18 VAC to 30 VAC. If the over/under voltage shutdown lasts
for 15 minutes, the lockout and alarm relay will be energized.
Over/under voltage shutdown is self-resetting in that if the
voltage comes back within range of 18 VAC to 30 VAC for at
least 0.5 seconds, then normal operation is restored.
HydroLink Aurora Chiller Controls cont.y
Operation DescriptionPower Up - The unit will not operate until all the inputs and safety controls are checked for normal conditions. The unithas a 5 to 80 second random start delay at power up. Thenthe compressor has a 4 minute anti-short cycle delay after the
random start delay.
Standby - In standby mode, Y1, Y2, W, DH, and G are not
active. Input O/B may be active. The compressor will be off.
Heating Operation
This product generally utilizes a “B” reverse cycle selection of the O/B reversing valve operation. In all heating operations, the reversing valve directly tracks the B input. Thus, anytime the B input is present, the reversing valve will be energized forheating mode. This means a failure of the reversing valve willstill allow cooling mode operation. The lead/lag circuit will switch between circuit A and B at every start up to even runtime between circuits. Therefore Stage 1 can energize Circuit Aor B depending upon the state of the lead/lag circuit.
Dual Compressor Heating, 1st Stage (Stage 1, B) The stage 1 compressor will be staged to full capacity 20
seconds after Y1 input is received at ABC A.
Dual Compressor Heating, 2nd Stage (Stage 1, Stage 2, B)The stage 2 compressor will be engaged to full capacity 30 seconds after Y2 input is received at the ABC A board.
Cooling Operation
This product generally utilizes a “B” reverse cycle selection of the O/B reversing valve operation. In all cooling operations,the reversing valve inversely tracks the B input. Thus, anytime the B input is NOT present, the reversing valve will be de-energized for cooling mode. This means a failure of thereversing valve will still allow cooling mode operation. The lead/lag circuit will switch between circuit A and B at everystart up to even run time between circuits. Therefore Stage 1can energize Circuit A or B depending upon the state of the
lead/lag circuit.
Dual Compressor Heating, 1st Stage (Stage 1, B) - The stage 1
compressor will be staged to full capacity 20 seconds after Y1
input is received at the ABC A board.
Dual Compressor Heating, 2nd Stage (Stage 1, Stage 2, B) - The stage 2 compressor will be engaged to full capacity 30
seconds after Y2 input is received at the ABC A board.

Other Modes of Operation Emergency Shutdown - Four (4) seconds after a valid ES
input or communicated signal, P2-7 is present, all control
outputs will be turned off and remain off until the emergency
shutdown input is no longer present. The first time that the
compressor is started after the control exits the emergency
shutdown mode, there will be an anti-short cycle delay
followed by a random start delay. Input must be tied to
common to activate.
Load Shed - The LS input or communicated signal disables all
outputs with the exception of the blower output. When the LS
input has been cleared, the anti-short cycle timer and random
start timer will be initiated. Input must be tied to common
to activate. These feature can be applied to Circuit A or B
individually.
Aurora ‘Base’ Control LED Displays - Although the HydroLink
Aurora comes with a 10” color touch tablet, the ABC does
have LED’s for reading basic status and fault codes. These
three LEDs display the status, configuration, and fault codes
for the control. These can also be read in plain English via the

Hydrolink Aurora in BAS ApplicationsThe HydroLink Aurora is designed to allow chillers to be
integrated into Building Automation Systems (BAS) with
ease. The HydroLink Aurora is an integrated solution and
communicates directly with the Aurora Heat Pump Controls
and allows access/control of a variety of internal Aurora heat
pump operations such as sensors, relay operation, faults and
other information. In turn, the HydroLink then converts internal
Aurora Modbus protocol to BACnet MS/TP or LON protocols
and communicates to the BAS system. This provides the
great benefit of complete control integration and a myriad of
information available to the BAS from the heat pump control.
Plus it also allows individual unit configuration such as freeze
protection setting directly over the BAS without the need
for access to the actual heat pump. The HydroLink Aurora is
programmed using the powerful NiagaraAX language.. This
will allow for a BAS to integrate and communicate to the heat
pump thru a choice of 2 different communication protocols.
The HydroLink Aurora includes a configurable wireless 10”
color touch tablet. There are an extensive number of points
that the HydoLink Aurora has available over the network
for integration into the BAS. Control programmers need to
carefully determine which points they want to add into the
BAS database. Consult your factory representative for more
information on BAS integration.

Temperature Control Settings ScreenThe unit will operate with 3 different control methods. The three options include, Setpoint Control using selectable onboard
sensors and a PID loop, Aquastat mode using external (field supplied) 24V temperature sensor and 24VAC commands directly
to the unit, Network Mode with operation commands directly thru BACnet/LON communication. These are selectable in the
Temperature control Settings Window.
Setpoint Control MethodIn Setpoint control the unit will maintain setpoint based upon the internal (and modifiable) PID algorithm. In this mode several
sensors can be selected and used for sensing. The entering load temperature (ELT), or leaving load temperature (LLT) are
onboard sensors that can be selected for this use. The remote sensor, a 10k NTC thermistor that is hooked up to P17-HW inputs
(bare wire provided) on the AXB-B board, allows for an external sensor application. The last option is the Network Sensor that
can be selected and communicated thru BACnet or Lon and used as the controlling sensor. The network sensor also relies on the
internal PID algorithm as the other 3. The compressors will have lead/lag capability in this method.
AquaStat Control Method
In Aquastat control the unit will operate based upon 24VAC control signals into the Y1 (stage 1), Y2 (stage 2), and B (heating) P1
inputs on ABC-A using an external to the unit aquastat temperature sensing and setpoint control system. The compressors will
have lead/lag capability.
Network Control Method
In Network Control the unit will operate based upon communicated Y1 (stage 1), Y2 (stage 2), and B (heating) points thru the
BACnet or Lon system. See BACnet Points lists for specifics. The compressors will have lead/lag capability.
The following are only available for selection in Setpoint Mode.
• Mode – Allows the selection of heating, cooling, and auto. Remote Sensor Calibration.
• Remote Sensor Calibration – Allows the remote sensor to be ‘calibrated’ using an offset temperature. Enter -1 to lower the
reading to match a reference measurement and 1 to raise the reading by a degree.

Energy Monitoring
Energy Compressor Monitoring – In Comp Monitoring the current transducers are only used for compressor locked rotor
start timing or welded contact fault monitoring of the compressor contactor producing an E10 fault. In Energy monitoring
adds power measurement to Comp monitoring and displays operating power of each compressor in Watts.
Measured Line Voltage Calibration – The HydroLink Aurora monitors the line Voltage of the unit after the control trans-
former. Upon installation, it is required that the supply Voltage be measured with the unit operating with one stage com-
pressor. Enter this measured Voltage value into this cell. The control will track the line Voltage as it fluctuates using this
calibration factor.
Supply Power Phase Selection – the selection of the unit supply power for use in unit power calculation.
Performance Monitoring
Source Flow Meter – An optional field installed flow meter for the source fluid is available to measure fluid flow of the unit.
The meter has an accuracy of ±3%. The flow meter is required to calculate HE/HR. Use this to select the appropriate flow
meter model.
Source Liquid Density – Select the appropriate liquid density factor of the source fluid. Typically 500 [4.2] is used for pure
water and 485 [4.1] is used for antifreezes solutions. 500 [4.2] is the default
Load Flow Meter – An optional field installed flow meter for the load fluid is available to measure fluid flow of the unit. The
meter has an accuracy of ±3%. The flow meter is required to calculate unit capacity at the load. Use this to select the ap-
propriate flow meter model.
Load Liquid Density – Select the appropriate liquid density factor of the load fluid. Typically 500 [4.2] is used for pure
water and 485 [4.1] is used for antifreezes solutions. 500 [4.2] is the default.

Modular Scroll Series Application Requirementspp q1.0. Minimum Fluid Volume
A. Water-to-water Chillers require a minimum amount ofsource and load side fl uid volume to ensure accurate and stable temperatures during system operation. For normal air conditioning type applications, it isrecommended to use at least 7 gallons/ton.
B. Applications that require more precise temperaturecontrol or low loading will occur the minimum fl uid volume shall be no less than 10 gallons/ton. Installation of a buffer tank that will properly mix thefl uid is recommended.
1.1. Chiller Sizing
A. Chillers should be adequately sized for optimal systemeffi ciency and run time.
B. In applications where the minimum load is signifi cantlyless than the design condition, it is better to install 2 smaller Chillers for load matching rather than a single large Chiller.
1.2. Chiller Piping
A. The preferred system design is to pipe the equipment in parallel due to its simplicity and fl exibility. In parallelsystems, the Chiller equipment can vary in size as long as fl ow rate and system volume are accounted for.
B. Piping equipment in series is not desired; however, it can be done if proper guidelines are followed.Always observe proper temperature and fl ow rate requirements for each unit. Sometimes this method is desired to achieve larger temperature differences.
1.3. Strainers
A. All brazed-plate heat exchangers shall have astrainer within 8 ft of the water/brine inlet. It is highlyrecommended to use a 30-40 mesh in order to providemaximum fi ltration. In any case, the strainers shouldnever have a mesh size less than 20.
B. Failure to install proper stainers and perform regularservice can result in serious damage to the unit, and cause degraded performance, reduced operating life and failed compressors. Improper installation of theunit (which includes not having proper strainers toprotect the heat exchangers) can also result in voiding the warranty.
C. Strainers should be selected on the basis of acceptable pressure drop, and not on pipe diameter. The strainers selected should have a pressure drop at the nominalfl ow rate of the units; low enough to be within the pumping capacity of the pump being used.
1.4. Flow Sensing Devices
A. A fl ow switch or equivalent must be installed on the evaporator for each unit to be installed. If the unit is to operate as both modes (heating/cooling), a fl ow switch is needed on both heat exchangers.
B. A differential pressure switch can be used in place of afl ow switch. The differential switch must be capable ofpressure range as indicated in the pressure drop tables.
1.5. Water Quality
A. General: Reversible chiller systems may be successfully applied in a wide range of commercial and industrial applications. It is the responsibility of the system designer and installing contractor to ensure that acceptable water quality is present and that all applicable codes have been met in these installations.
B. Water Treatment: Do not use untreated or improperly treated water. Equipment damage may occur. The use of improperly treated or untreated water in thisequipment may result in scaling, erosion, corrosion, algae or slime. The services of a qualifi ed watertreatment specialist should be engaged to determine what treatment, if any, is required. The productwarranty specifi cally excludes liability for corrosion, erosion or deterioration of equipment.
The heat exchangers in the units are 316 stainless steel plates with copper brazing. The water piping in the heat exchanger is steel. There may be other materials in the building’s piping system that the designer may need to take into consideration when deciding the parameters of the water quality.
If an antifreeze or water treatment solution is to be used, the designer should confi rm it does not have adetrimental effect on the materials in the system.
C. Contaminated Water: In applications where the water quality cannot be held to prescribed limits, the use of a secondary or intermediate heat exchanger is recommended to separate the unit from thecontaminated water.
The following table outlines the water quality guidelines for unit heat exchangers. If these conditions are exceeded, a secondary heat exchanger is required.Failure to supply a secondary heat exchanger whereneeded will result in a warranty exclusion for primaryheat exchanger corrosion or failure.
WARNING: Must have intermediate heat exchanger when used in pool applications.
69
WC MODULAR SCROLL CHILLER SPECIFICATION CATALOG
Modular Scroll Application Requirements cont.pp q1.6. Insulation
A. Chillers are built with factory installed insulation on anysurface that may be subject to temperatures below theroom dew point.
1.7. Brine Applications
A. Applications where the leaving fl uid temperature goesbelow 40°F a suitable brine solution must be used. Failure to do so can cause immediate damage to thesystem. The brine must be approved for use with heat exchangers. Automotive antifreeze solutions are notsuitable for use in brazed plate heat exchangers.
B. The freeze detection must be adjusted appropriatelyfor brine applications. The brine solution concentration should be at least 15°F below thelowest leaving fl uid temperature.

Application NotesppThe following general application notes are intended to describe general common design practices for these chillers. More
detailed explanation resides in the installation, operation and maintenance manual.
Piping ConsiderationsWhen Piping multiple units in a bank, reverse return piping is recommended to ensure adequate even water flow through eachchiller circuit, however in banks of less than 4 chiller modules, Non-reverse return (direct return ) piping can be used success-fully. For modules containing more than 7 chillers please consult the factory. The water flow can be reversed from that shown. A pressure differential flow sensor should be considered if uneven flow situations are anticipated which can potentially cause low flow and damage to the chillers. A stainless steel strainer of at least 30 mesh is require to limit debris entering the supply
side water entering the chillers and must be in place at all times.
Bypass HeaderA bypass circuit is recommended on any system employing modulating valves as are commonly found in the header rack. The bypass can be installed at either end of the bank, however if it includes a temperature sensor, care should be taken to ensure the desired sensor measurement is not effected by the location of the sensor (in a dead section of pipe) or the position of thebypass valve where bypass fluid will alter the temperature measured. A bypass header with flexible temp or pressure sensing ports is available. See the temperature header for more detail on these ports. A pressure sensor may also be required to shut
off chillers in case of poor header flow. Consult the bypass header drawing for details.
Temperature HeaderA temperature header consists of a grooved pipe with dual ports, one of which has a temperature sensor installed. These headers are meant to be located in the piping immediately after the chiller bank to monitor the resulting (global) tempera-ture effect of the whole bank. In some applications this global temperature can more effectively be used for setpoint controlof each chiller rather than the local temperature sensor located on the outlet of each chiller pipe. Consult the bypass header
drawing for details.
Chiller Sensor ConnectionsChiller connections are illustrated below for clarity. Temperature sensors are located inside with pressure/temperature ports on the outside plugs for easy access. Flow sensors should be installed in the top ports of the leaving connection of each heat exchanger as shown. Optional sensors or equipment can be installed in the spare plug locations if needed. Note that the pressure temperature port bushing should be accessible and removed for flushing or draining of the heat ex-
changer.

Abbreviations and Definitions
Reference CalculationsHeating Calculations: Cooling Calculations:
LWT = EWT + HR
GPM x 500*LWT = EWT -
NOTE: * When using water.
ELT = entering load fluid temperature to heat pump
EER = cooling energy effciency (TC/KW)
LLT = leaving load fluid temperature from heat pump
PSI = pressure drop in pounds per square inch
LGPM = load flow in gallons per minuteFT HD = pressure drop in feet of head
LWPD = load heat exchanger water pressure dropKW = kilowatt
EST = entering source fluid temperature to heat pump
HR = heat rejected in MBTUH
LST = leaving source fluid temperature from heat pumpTC = total cooling capacity in MBTUH
SGPM = source flow in gallons per minuteCOP = coefficient of performance (HC/KW x 3.413)
SWPD = source heat exchanger water pressure dropHC = heating capacity in MBTUHHE = heat of extraction in MBTUH
Notes to Performance Data Tables
The following notes apply to all performance data tables:• Three flow rates are shown for each unit. The lowest flow rate shown is used for geothermal open loop/well water systems
with a minimum of 50°F EST. The middle flow rate shown is the minimum geothermal closed loop flow rate. The highest
flow rate shown is optimum for geothermal closed loop systems and the suggested flow rate for boiler/tower applications.
• Water temperatures below 40°F assumes 15% antifreeze solution.
• Interpolation between ELT, EST, and GPM data is permissible.
• Operation in the gray areas is not recommended.
• Any flow rate less than 2.5 GPM/per ton requires a flow switch

NOTES:1. Bypass valves are available with bypass option only in a single unit configuration. When multiple units are installed in tandem, the bypass valves are wired through the supervisory controller.2. If the pipe rack is configured as “6 pipe dedicated”, the source valves are eliminated and the unit is equipped only with load valves. 3. The unit is equipped with IO34 only for options that require controlling source, load and bypass valves4. BACnet addressing can be done through the unit mounted HMI .5. If no IO34 is present, the hydrolink is power directly from the power supply board (PSB)..6. SW2-3 MUST BE SET TO “OFF”. This Ensures that freeze protection is active.
