Installation Instructions
SAFETY CONSIDERATIONS
Centrifugal liquid chillers are designed to provide safe and
reliable service when operated within design specifications.
When operating this equipment, use good judgment and safety
precautions to avoid damage to equipment and property or
injury to personnel.
Be sure you understand and follow the procedures and safety
precautions contained in the machine instructions, as well
as those listed in this guide.
DO NOT VENT refrigerant relief devices within a building. Outlet from
rupture disc or relief valve must be vented outdoors in accordance with
the latest edition of ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) 15. The accumulation of refrigerant in an enclosed space can displace oxygen and cause
asphyxiation.
PROVIDE adequate ventilation in accordance with ASHRAE 15, especially for enclosed and low overhead spaces. Inhalation of high
concentrations of vapor is harmful and may cause heart irregularities,
unconsciousness, or death. Intentional misuse can be fatal. Vapor is
heavier than air and reduces the amount of oxygen available for breathing. Product causes eye and skin irritation. Decomposition products are
hazardous.
DO NOT USE OXYGEN to purge lines or to pressurize a machine for
any purpose. Oxygen gas reacts violently with oil, grease, and other
common substances.
DO NOT USE air to leak test. Use only refrigerant or dry nitrogen.
NEVER EXCEED specified test pressures. VERIFY the allowable test
pressure by checking the instruction literature and the design pressures
on the equipment nameplate.
DO NOT VALVE OFF any safety device.
BE SURE that all pressure relief devices are properly installed and functioning before operating any machine.
DO NOT WELD OR FLAMECUT any refrigerant line or vessel until
all refrigerant (liquid and vapor) has been removed from chiller. Traces
of vapor should be displaced with dry air or nitrogen and the work area
should be well ventilated. Refrigerant in contact with an open flame
produces toxic gases.
DO NOT USE eyebolts or eyebolt holes to rig machine sections or the
entire assembly.
DO NOT work on high-voltage equipment unless you are a qualified
electrician.
DO NOT WORK ON electrical components, including control panels,
switches, starters, or oil heater until you are sure ALL POWER IS OFF
and no residual voltage can leak from capacitors or solid-state
components.
LOCK OPEN AND TAG electrical circuits during servicing. IF WORK
IS INTERRUPTED, confirm that all circuits are deenergized before
resuming work.
AVOID SPILLING liquid refrigerant on skin or getting it into the eyes.
USE SAFETY GOGGLES. Wash any spills from the skin with soap
and water. If liquid refrigerant enters the eyes, IMMEDIATELY FLUSH
EYES with water and consult a physician.
NEVER APPLY an open flame or live steam to a refrigerant cylinder.
Dangerous over pressure can result. When it is necessary to heat refrigerant, use only warm (110 F [43 C]) water.
DO NOT REUSE disposable (nonreturnable) cylinders or attempt to
refill them. It is DANGEROUS AND ILLEGAL. When cylinder is emptied, evacuate remaining gas pressure, loosen the collar, and unscrew
and discard the valve stem. DO NOT INCINERATE.
CHECK THE REFRIGERANT TYPE before adding refrigerant to the
machine. The introduction of the wrong refrigerant can cause
machine damage or malfunction.
Operation of this equipment with refrigerants other than those cited
herein should comply with ASHRAE-15 (latest edition). Contact
Carrier for further information on use of this machine with other
refrigerants.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc., while
machine is under pressure or while machine is running. Be sure pressure is at 0 psig (0 kPa) before breaking any refrigerant connection.
CAREFULLY INSPECT all relief valves, rupture discs, and other relief devices AT LEAST ONCE A YEAR. If machine operates in a corrosive atmosphere, inspect the devices at more frequent intervals.
DO NOT ATTEMPT TO REPAIR OR RECONDITION any relief valve
when corrosion or build-up of foreign material (rust, dirt, scale, etc.) is
found within the valve body or mechanism. Replace the valve.
DO NOT install relief devices in series or backwards.
USE CARE when working near or in line with a compressed spring.
Sudden release of the spring can cause it and objects in its path to act
as projectiles.
DO NOT STEP on refrigerant lines. Broken lines can whip about, and
release refrigerant, causing personal injury.
DO NOT climb over a machine. Use platform, catwalk, or staging. Follow safe practices when using ladders.
USE MECHANICAL EQUIPMENT (crane, hoist, etc.) to lift or move
inspection covers or other heavy components. Even if components are
light, use mechanical equipment when there is a risk of slipping or
losing your balance.
BE AWARE that certain automatic start arrangements CAN ENGAGE
THE STARTER, TOWER FAN OR PUMPS. Open the disconnect ahead
of the starter, tower fan, and pumps. Shut off the machine or pump
before servicing equipment.
USE only repaired or replacement parts that meet the code requirements of the original equipment.
DO NOT VENT OR DRAIN waterboxes containing industrial brines,
liquid, gases, or semisolids without the permission of your process control group.
DO NOT LOOSEN waterbox cover bolts until the waterbox has been
completely drained.
DOUBLE-CHECK that coupling nut wrenches, dial indicators, or other
items have been removed before rotating any shafts.
DO NOT LOOSEN a packing gland nut before checking that the nut
has a positive thread engagement.
PERIODICALLY INSPECT all valves, fittings, and piping for corrosion, rust, leaks, or damage.
PROVIDE A DRAIN connection in the vent line near each pressure
relief device to prevent a build-up of condensate or rain water.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.

*If a machine configuration other than 2-pass, 150 psig (1034 kPa), NIH waterbox configuration is used, refer to Tables 3
and 4 to obtain the additional dry and water weights that must be added to the values shown in this table.
†Cooler and condenser weights shown are based upon 2-pass, nozzle-in-head (NIH) waterboxes with 150 psig (1034 kPa)
covers. Includes components attached to cooler, but does not include suction/discharge, elbow, or other interconnecting
piping.
**Dry weight includes all components attached to economizer: Covers, float valves, brackets, control center (31 lb [14 kg]),
and power panel (20 lb [9 kg]). Dry weight does not include compressor weight, motor weight, or pumpout condensing unit
weight. The pumpout condensing unit weight is 210 lb (95 kg). For compressor and motor weights, refer to Tables 6, 7, 8,
10A, and 10B.
††Operating weight includes the sum of the dry weight, refrigerant weight, and water weight.

*The 150 psig (1034 kPa) 2-pass waterbox cover weights are included in the dry weight shown in Table 1.
†Two different waterbox covers are present on 2-pass machines. The weight shown in this table represents the weight
of the waterbox cover that contains the nozzles. A blank waterbox cover is also present on 2-pass units. The weight
of the blank waterbox cover is identical to the weight of the same size marine waterbox cover. Refer to Table 11.
3. Grout must extend above the base of the soleplate and
there must be no voids in grout beneath the plates.
4. Allow grout to set and harden, per manufacturer’s instructions, before starting machine.
5. Remove jacking screws from leveling pads after grout has
hardened.
INSTALL SPRING ISOLATION — Field-supplied spring
isolators may be placed directly under machine support plates
or be located under machine soleplates. Consult job data for
specific arrangement. Low profile spring isolation assemblies are recommended so that the machine is kept at a convenient working height inside of the tube sheet.
Obtain specific details on spring mounting and machine
weight distribution from job data. Also, check job data for
methods for supporting and isolating pipes that are attached
to the spring-isolated machines.
Install Machine Supports
INSTALL STANDARD ISOLATION — Figures 10 and 11
show the position of support plates and shear flex pads, which
together form the standard machine support system.
INSTALL OPTIONAL ISOLATION (if required) — Uneven floors or other considerations may dictate the use of
soleplates and leveling pads. Refer to Fig. 10 and 11.
Level machine by using jacking screws in isolation soleplates. Use a level at least 24 in. (600 mm) long.
For adequate and long lasting machine support, proper grout
selection and placement is essential. Carrier recommends that
only pre-mixed, epoxy-type, non-shrinking grout be used for
machine installation. Follow manufacturer’s instructions in
applying grout.
1. Check machine location prints for required grout
thickness.
2. Carefully wax jacking screws for easy removal from grout.

City water must be clean and noncorrosive. Water side
erosion or corrosion of the oil cooler coil may lead to
extensive machine damage not covered by the standard
warranty.
If water from the machine chilled water circuit is used for
oil cooling, it should enter the oil cooler from the entering
water line of the machine cooler. Water leaving the oil cooler
should connect to the leaving water line of the machine cooler
at a point downstream from the chilled water sensor, so that
oil cooler leaving water temperature does not affect the sensor readings.
Locate the oil cooler leaving water connection at some
distance from any water temperature indicators. On singlepass machines, water leaving the oil cooler should be connected into the suction side of the chilled water pump so that
adequate pressure drop is assured for oil cooling.
The nominal conditions for oil cooler water flow are:
Flow rate . . . . . . . . . . . . . . . . . . . . . . . 30 gpm (1.9 L/s)
Leaving temperature . . . . . . . . 85 to 100 F (29 to 38 C)
Pressure drop at oil cooler . . . . . . . 7.25 psid (50 kPad)
Max differential pressure across closed
solenoid valve . . . . . . . . . . . . . . 150 psid (1034 kPad)
The oil cooler connections are 11⁄4 in. FPT.
Fig. 14 — Pumpout Unit
INSTALL WATER TO OIL COOLER ON FA COMPRESORS — On FA compressors, water must be piped to the oil
cooler heat exchanger (located under the suction pipe to the
compressor). The water supply may be either city water or
chilled water. Pipe city water to an open sight drain. Chilled
water enters via the cooling entering water intake (Fig. 15).

Fig. 16 — Typical 17/19EX Utility Vessel
Relief Valve Tee
Fig. 15 — Water Piping, Oil Cooler to
Chilled Water Circuit (Typical)
Do not run 120-v wiring into the control center. The
control center should only be used for additional extra
low-voltage wiring (50 v maximum).
INSTALL VENT PIPING TO RELIEF DEVICES — The
17/19EX chiller is factory equipped with relief devices on
the cooler and utility vessels. Refer to Fig. 2 and 3, and
Table 13 for size and location of relief devices, as well as
information that will help determine pipe size. Vent relief
devices to the outdoors in accordance with ASHRAE 15
(latest edition) Safety Code for Mechanical Refrigeration and
all other applicable codes. To ensure relief valve serviceability, and as required in ASHRAE 15, latest edition, 3-way
dual shutoff valves and redundant relief valves are installed
on the economizer/storage vessel, refer to Fig. 16.
NOTE: The 3-way dual shutoff valve should be either front
seated or back seated. Running the refrigeration system with
the valve stem in the center position can reduce total relief
capacity and cause valve chattering.
Wiring diagrams in this publication (Fig. 17-23) are for
reference only and are not intended for use during actual installation; follow job specific wiring diagrams.
Specific electrical ratings for individual components are
shown in Table 14.
Do not attempt to start compressor or oil pump — even
for a rotation check — or apply test voltage of any kind
while machine is under dehydration vacuum. Motor insulation breakdown and serious damage may result.
CONNECT CONTROL INPUTS — Connect the control input wiring from the chilled and condenser water flow switches
to the starter terminal strip. Wiring may also be specified for
a spare safety switch, and a remote start/stop contact can be
wired to the starter terminal strip, as shown in Fig. 17 and
18. Additional spare sensors and Carrier Comfort Network
modules may be specified as well. These are wired to the
machine control center as indicated in Fig. 22 and 23.
CONNECT CONTROL OUTPUTS — Connect auxiliary
equipment, chilled and condenser water pumps, and spare
alarms as required and indicated on job wiring drawings.
Connect Starter — Assemble and install compressor terminal box in desired orientation, and cut necessary conduit openings in conduit support plates. Attach power leads to compressor terminals in accordance with job wiring drawings,
observing caution label in terminal box. Use only copper conductors. The motor must be grounded in accordance with
NEC (National Electrical Code), applicable local codes, and
job wiring diagrams.
Refrigerant discharged into confined spaces can displace oxygen and cause asphyxiation.
1. If relief device piping is manifolded, the cross-sectional
area of the relief pipe must at least equal the sum of the
areas required for individual relief pipes.
2. Provide a pipe plug near outlet side of each relief device
for leak testing. Provide pipe fittings that allow vent piping to be disconnected periodically for inspection of valve
mechanism.
3. Piping to relief devices must not apply stress to the
device. Adequately support piping. A length of flexible
tubing or piping near the device is essential on springisolated machines.
4. Cover the outdoor vent with a rain cap and place a condensation drain at the low point in the vent piping to prevent water build-up on the atmospheric side of the relief
device.
IMPORTANT: Do not insulate terminals until wiring
arrangement has been checked and approved by
Carrier start-up personnel. Also, make sure correct phasing is followed for proper motor rotation.
Make Electrical Connections — Field wiring must
be installed in accordance with job wiring diagrams and all
applicable electrical codes.
20
Insulate Motor Terminals and Lead Wire Ends — Insulate
compressor motor terminals, lead wire ends, and electrical
wires to prevent moisture condensation and electrical arcing. For low-voltage units (up to 600 v), insulate the electrical terminals as follows:
1. Insulate each terminal by wrapping with one layer of
insulation putty.
2. Overwrap putty with 4 layers of vinyl tape.
High-voltage units require special terminal preparation. The
vinyl tape is not acceptable; a high voltage tape must be used.
Installer is responsible for any damage caused by improper
wiring between starter and compressor motor.
Connect Power Wires to Oil Pump Contactor — Connect power
wires to oil pump contactor mounted in machine power panel.
(See Fig. 19.) Use the electrical disconnect located in the
machine starter (if supplied), or a separate fused disconnect
as shown on job wiring diagrams. Check that power supply
voltage agrees with oil pump voltage. Follow correct phasing for proper motor rotation.
Connect Power Wires to Oil Heater Contactor — Connect
control power wiring between the oil heater contactor terminals (Fig. 17 and 18) and terminals LL1 and LL2 on the
field wiring strip in the compressor motor starter. Refer to
Fig. 21 and wiring label on the chiller power panel.
Voltage to terminals LL1 and LL2 comes from a control transformer in a starter built to Carrier specifications. Do not connect an outside source of control power
to the compressor motor starter (terminals LL1 and LL2).
An outside power source will produce dangerous voltage at the line side of the starter, because supplying voltage at the transformer secondary terminals produces input level voltage at the transformer primary terminals.
Connect Communication and Control Wiring from Starter to
Power Panel — Connect control wiring from main motor starter
to the chiller power panel. All control wiring must use shielded
cable. Also connect the communications cable. Make sure
the control circuit is grounded in accordance with applicable
electrical codes and instructions on chiller control wiring
label.
Do not wire into the top surface of the power panel. Knockouts are provided on the underside of the panel.

2. Relief valve discharge pipe sizing is to be calculated per latest
version of ASHRAE 15, using the tabulated C-factors and nominal pipe size listed above. Cooler and economizer/storage vessel rated relief valve pressure is 225 psig (1551 kPa).
3. The pumpout unit condenser contains less than 110 lb (50 kg) of
HFC-134a, which is a Group A1 refrigerant. The ASHRAE 15 standard exempts small-volume vessels from the requirement to vent
outside. However, Carrier recommends that the pumpout condenser be connected to the rest of the vent system.
NOTES:
1. The cooler relief C-factor is for both cooler and condenser vented
through the cooler in accordance with ASHRAE (American
Society of Heating, Refrigeration, and Air Conditioning Engineers) 15, latest edition.

3.4 Do not route control wiring carrying 30 v or less within a conduit which has wires
carrying 50 v or higher or along side wires carrying 50 v or higher.
3.5 Voltage selector switch in machine power panel is factory set for 115 v control power
source. Do not use the 230 v position. If this switch is set to 230 v position, the oil
heater will not operate.
3.6 Control wiring cables between starter and power panel must be shielded with minimum rating of 600 v, 80 C ground shield at starter. Wires A,B, and C are communication wires and must be run in a separate cable.
3.7 If optional oil pump circuit breaker is not supplied within the starter enclosure as
shown, it must be located within sight of the machine with wiring routed to suit.
3.8 Voltage to terminals LL1 and LL2 comes from a control transformer in a starter built
to Carrier specifications. Do not connect an outside source of control power to the
compressor motor starter (terminals LL1 and LL2). An outside power source will
produce dangerous voltage at the line side of the starter, because supplying voltage
at the transformer secondary terminals produces input level voltage at the transformer primary terminals.
IV. POWER WIRING BETWEEN STARTER AND COMPRESSOR MOTOR
4.0 Low voltage (600 v or less) compressor motors have (6), 5⁄8 in. terminal studs (lead
connectors not supplied by Carrier). Either 3 or 6 leads must be run between compressor motor and starter, depending on type of motor starter employed. If only 3
leads are required, jumper motor terminals as follows: 1 to 6, 2 to 4, 3 to 5. Center
to center distance between terminals is 215⁄16 inches. Compressor motor starter must
have nameplate stamped as to conforming with Carrier requirement Z-375. Medium
voltage (over 600 v) compressor motors have (3) terminals. Connections out of terminals are 3 in. long stranded wire pigtails, #4 AWG, strand wire for all medium
voltage motor sizes. Distance between terminal is 79⁄16 inches. Use suitable splice
connectors and insulation for high voltage alternating current cable terminations (these
items are not supplied by Carrier). Compressor motor starter must have nameplate
stamped as to conforming with Carrier requirement Z-375.
4.1 When more than one conduit is used to run conductors from starter to compressor
motor terminal box, one conductor from each phase must be in each conduit to
prevent excessive heating. (e.g., conductors to motor terminals 1, 2 and 3 in one
conduit, and those to 4, 5 and 6 in another.)
4.2 Compressor motor power connections can be made through top, top rear or sides
of compressor motor terminal box using holes cut by contractor to suit conduit. Flexible conduit should be used for the last few feet to the terminal box for unit vibration
isolation. Use of stress cones or 12 conductors larger than 500 MCM may require
an oversize (special) motor terminal box (not supplied by Carrier). Lead connections between 3-phase motors and their starters must not be insulated until Carrier
personnel have checked compressor and oil pump rotations.
4.3 Compressor motor frame to be grounded in accordance with the National Electrical
Code (NFPA-70) and applicable codes. Means for grounding compressor motor is
a pressure connector for #4 to 500 MCM wire, supplied and located in the back
lower left side corner of the compressor motor terminal box.
4.4 Do not allow motor terminals to support weight of wire cables. Use cable supports
and strain reliefs as required.
4.5 Use backup wrench when tightening lead connectors to motor terminal studs. Torque
to 45 lb-ft max.

At each system element, the shields of its communication
bus cables must be tied together. If the communication bus
is entirely within one building, the resulting continuous shield
must be connected to ground at only one single point. See
Fig. 23. If the communication bus cable exits from one building and enters another, the shields must be connected to ground
at the lightning suppressor in each building where the cable
enters or exits the building (one point only).
To connect the 17/19EX chiller to the network, proceed
as follows (Fig. 23):
1. Cut power to the PIC (Product Integrated Control) panel.
2. Remove the COMM1 plug from the processor module.
3. Cut a CCN wire and strip the ends of the RED, WHITE,
and BLACK conductors.
4. Using a wirenut, connect the drain wires together.
5. Insert and secure the RED wire to Terminal 1 of the
COMM1 plug.
