The True 'Modular' Concept
p
Most modular chillers can be ganged together but once in place cannot be easily serviced or removed. WaterFurnace
modular scroll units feature several industry firsts to provide a true modular chiller!
1.
Modular chiller unit can be removed from the bank and replaced with a new unit using strategically placed fork truck
pockets.
2.
Majority of servicing can be accomplished from front (control box) of unit. Zero service clearance on side. Top panels
are removable with unit in place.
3.
Chiller section can be separated from the pipe rack for service or replacement with pipe rack remaining plumbed and
intact due to the isolation valves at the pipe rack.
4.
Hinged low voltage control box allows easy service access to refrigerant circuit such as TXV, switches and transducers.
5.
Removable control box for servicing the compressor through the control box side while keeping the piping all in place.

WC MODULAR SCROLL CHILLER SPECIFICATION CATALOG
Inside the Modular Scroll Chiller Series
An optional electronic expansion valve (EEV) may be utilized
on 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.
Cabinet
All unit frames are constructed
of heavy gauge steel channel and
painted with a corrosion resistant
polyester powder coat paint. The
sheet metal cabinets are constructed
of heavy gauge galvanized sheet
steel painted with polyester powder
coat paint rated at more than a 1,000
hours salt spray rating. The frame
includes fork truck access pockets in two dimensions and
lifting points for easy maneuvering during installation and
servicing.
Strainers (Accessory)
All chillers shall have a field-installed
accessory strainer either Y-type or
basket type. Strainers are made of a
suitable body such as brass with 316
stainless steel screens with a minimum
of 30 mesh.
Compressors
Flow Switch
Scroll chillers use high efficiency R-410A,
hermetically sealed, scroll compressors
that are mounted on rubber grommets
for vibration isolation. Scroll compressors
provide high efficiency while providing
greater tolerance to liquid refrigerant
entering the suction port.
All chillers come standard with a flow
switch, which prevents the unit from starting
under a no-flow or low flow condition. The
flow switches are monitored by the Aurora
Hydrolink controller, and status can be
reported to the BAS
Isolation Valves
All chillers have a motorized isolation
valve and a manual isolation valve on
each heat exchanger. The motorized
isolation valve is controlled by the
unit’s Aurora Hydrolink controller, and
is provided to isolate the unit from
flow when not in service to minimize
pumping requirements. The manual
and auto isolation valves can be shut
in the event the unit needs to be
separated from the optional pipe rack.
Water-to-Refrigerant Heat Exchanger
Large oversized stainless steel interlaced
dual circuit copper-brazed plate waterto-refrigerant heat exchangers provide
unparalleled efficiency. The heat exchangers
have a common water circuit with isolated
dual refrigerant circuits so that in part
load operation, the full mass of the heat
exchanger is utilized. All heat exchangers
are pressure rated to 450 psi water side and
650 psi refrigerant side. All heat exchangers,
water lines, and suction lines are insulated
to prevent condensation during low
temperature inlet water operation.
Compressor Protection Module
Some chillers come with external compressor protection
module that provides additional motor protection such as
reverse phase detection and a pre-wire thermistor.
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.
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 reliability. The reversing valve operates
when heating the load and defaults
to cooling mode.

Header Pipe
p Rack
Adding 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.

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.

The 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 operate as if there is not a header rack connected to the system.

Aurora Chiller Controls
Overview
HydroLink Control
The 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.
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.
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.
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.
There are several factory installed components so that each
chiller has built-in refrigeration, energy, and performance
monitoring capabilities.
NOTE: Refer to the Aurora Base Control Application and
Troubleshooting Guide and the Instruction Guide: Aurora
Interface and Diagnostics (AID) Tool for additional information.

Software Features
DIP Switch (SW1) – Test/Configuration Button (See SW1
Operation Table)
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.
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 pressing 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.
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.
Reset Configuration Mode
Anti-Short Cycle Protection – 5 minute anti-short cycle
protection for the compressor.
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.
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.
DIP Switch (SW2)
SW2-1 FP1 Selection – Low water coil temperature limit setting
for freeze detection. On = 30°F [-1.1 °C]; Off = 15°F [-9.4°C].
On is default.
SW2-2 FP2 Selection – On = 30°F [-1.1 °C]; Off = N/A. On is
default.
SW2-3 RV – O/B - Reversing Valve Position. Normally cooling
"B" or normally heating "O" On = O; Off = B. B is default.
SW2-4 and 2-5 Access Relay Operation (P2). On and On is
default.
SW2-6 CC Operation – selection of single or dual capacity
compressor. On = Single Stage; Off = Dual Capacity. On is
default.

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 type
identification 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.
SW2-7 Lockout and Alarm Outputs (P2) – selection of a
continuous or pulsed output for both the LO and ALM
Outputs. On = Continuous; Off = Pulsed. On is default.
SW2-8 Future Use. On is default.
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.
Alarm Jumper Clip Selection
From the factory, ALM is connected to 24 VAC via JW2. By
cutting JW2, ALM becomes a dry contact connected to ALG.
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.

Freeze Detection - Refrigerant (Source – E5 or Load
HX 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.
Operation Description
Power Up - The unit will not operate until all the inputs and
safety controls are checked for normal conditions. The unit
has a 5 to 80 second random start delay at power up. Then
the 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 for
heating mode. This means a failure of the reversing valve will
still allow cooling mode 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.
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.
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.
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.
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 deenergized for cooling mode. This means a failure of the
reversing valve will still allow cooling mode 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.
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.

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.
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.

Other Modes of Operation
Hydrolink Aurora in BAS Applications
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.
The 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.
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 Touch Display.

Temperature Control Settings Screen
The 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 Method
In 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.
•
Heating and Cooling Setpoint – These are the setpoints respectively for heating and cooling. Only one can be selected at a
time.

Manual Commands Screen
HydroLink Aurora allows several manuals commands that can either be ‘network communicated’ or in some cases even hardwired
to the boards using a daisy chained grounding signal.
Emergency Shutdown – This command, either hard-wired as a grounded signal to P2 on either ABC-A or ABC-B or network
communicated (Emerg Shutdown), will immediately (5 sec) shutdown all compressor and any other outputs. This screen shows
whether it is active or not.
Load Shed A – This command, either hard wired as a grounded signal to P2 on ABC-A for Compressor A or network
communicated (Load Shed A), will immediately shutdown (5 sec) the appropriate compressor operation all other outputs are
unaffected. This screen shows whether it is active or not.
Load Shed B – This command, either hard wired as a grounded signal to P2 on ABC-B for Compressor B or network
communicated (Load Shed B), will immediately shutdown (5 sec) the appropriate compressor operation all other outputs are
unaffected. This screen shows whether it is active or not.
Manual Aquastat Override – When enabled allows manual operation of the unit using the following direct commands.
Test Mode – This network communicated command only
will speed up all timings by 16 times to aid in troubleshooting.
If Active this display will show Active and the ABC Board’s
Green LED will also fast flash when Test Mode is active. If
Test Mode is inactive this will show ‘normal’.
Circuit A, Circuit B and B (Heating) Commands – These
commands allow manual operation of the unit. If activated
(ON), Circuit A will engage the A compressor. Circuit B and
B (Heating) work similarly. This is a handy way to manually
turn on the compressor stages and check reversing valve
operation.

Requirements
q
B.
1.0. Minimum Fluid Volume
A.
B.
Water-to-water Chillers require a minimum amount of
source and load side fluid volume to ensure accurate
and stable temperatures during system operation.
For normal air conditioning type applications, it is
recommended to use at least 7 gallons/ton.
Applications that require more precise temperature
control or low loading will occur the minimum
fluid volume shall be no less than 10 gallons/ton.
Installation of a buffer tank that will properly mix the
fluid is recommended.
1.5. Water Quality
1.1. Chiller Sizing
A.
B.
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 this
equipment may result in scaling, erosion, corrosion,
algae or slime. The services of a qualified water
treatment specialist should be engaged to determine
what treatment, if any, is required. The product
warranty specifically excludes liability for corrosion,
erosion or deterioration of equipment.
Chillers should be adequately sized for optimal system
efficiency and run time.
In applications where the minimum load is significantly
less 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.
B.
A differential pressure switch can be used in place of a
flow switch. The differential switch must be capable of
pressure range as indicated in the pressure drop tables.
The preferred system design is to pipe the equipment
in parallel due to its simplicity and flexibility. In parallel
systems, the Chiller equipment can vary in size as long
as flow rate and system volume are accounted for.
Piping equipment in series is not desired; however,
it can be done if proper guidelines are followed.
Always observe proper temperature and flow rate
requirements for each unit. Sometimes this method is
desired to achieve larger temperature differences.
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 confirm it does not have a
detrimental effect on the materials in the system.
1.3. Strainers
A.
B.
C.
C.
All brazed-plate heat exchangers shall have a
strainer within 8 ft of the water/brine inlet. It is highly
recommended to use a 30-40 mesh in order to provide
maximum filtration. In any case, the strainers should
never have a mesh size less than 20.
Failure to install proper stainers and perform regular
service can result in serious damage to the unit, and
cause degraded performance, reduced operating life
and failed compressors. Improper installation of the
unit (which includes not having proper strainers to
protect the heat exchangers) can also result in voiding
the warranty.
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 nominal
flow rate of the units; low enough to be within the
pumping capacity of the pump being used.
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 where
needed will result in a warranty exclusion for primary
heat exchanger corrosion or failure.
WARNING: Must have intermediate heat
exchanger when used in pool applications.
1.4. Flow Sensing Devices
A.
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 the
contaminated water.
A flow 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 flow switch
is needed on both heat exchangers.

Failure to do so can cause immediate damage to the
system. The brine must be approved for use with heat
exchangers. Automotive antifreeze solutions are not
suitable for use in brazed plate heat exchangers.
The freeze detection must be adjusted appropriately
for brine applications. The brine solution
concentration should be at least 15°F below the
lowest leaving fluid temperature.

Notes
The 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 Considerations
When Piping multiple units in a bank, reverse return piping is recommended to ensure adequate even water flow through each
chiller circuit, however in banks of less than 4 chiller modules, Non-reverse return (direct return ) piping can be used successfully. 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 Header
A 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 the
bypass 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 Header
A 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) temperature effect of the whole bank. In some applications this global temperature can more effectively be used for setpoint control
of 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 Connections
Chiller 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 exchanger.

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 valves
4. 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.
