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 NOTVENTrefrigerant relief devices within a building. Outlet from
rupture disc or relief valve must be vented outdoors in accordance with
the latest edition of ANSI/ASHRAE 15 (American National Standards
Institute/American Society of Heating, Refrigeration and Air-Conditioning
Engineers) (Safety Code for Mechanical Refrigeration). The accumulation of refrigerant in an enclosed space can displace oxygen and cause
asphyxiation.
PROVIDE adequate ventilation in accordance with ANSI/
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 func-
tioning before operating any machine.
RISK OF INJURYOR DEA THby electrocution. High voltage is present
on motor leads even though the motor is not running when a solid state
or inside-delta mechanical starter is used. Open the power supply disconnect before touching motor leads or terminals.
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 sureALL POWER
IS OFF and no residual voltage can leak from capacitors or solid-state
components.
LOCK OPENAND 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, IMMEDIATELYFLUSH
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 ANSI/ASHRAE15 (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,TOWERFAN,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.

Receiving the Machine
INSPECT SHIPMENT
Do not open any valves or loosen any connections. The
standard 19XR machine is shipped with a full refrigerant charge. Some machines may be shipped with a nitrogen holding charge as an option.
1. Inspect for shipping damage while machine is still on shipping conveyance. If machine appears to be damaged or
has been torn loose from its anchorage, have it examined
by transportation inspectors before removal. Forward claim
papers directly to transportation company. Manufacturer
is not responsible for any damage incurred in transit.
2. Check all items against shipping list. Immediately notify
the nearest Carrier representative if any item is missing.
3. To prevent loss or damage, leave all parts in original packages until beginning installation. All openings are closed
with covers or plugs to prevent dirt and debris from entering machine components during shipping. A full operating oil charge is placed in the oil sump before
shipment.
IDENTIFY MACHINE — The machine model number,
serial number, and heat exchanger sizes are stamped on
machine identification nameplate (Fig. 1 and 2). Check this
information against shipping papers and job data.
PROVIDE MACHINE PROTECTION — Protect machine
and starter from construction dirt and moisture. Keep protective shipping covers in place until machine is ready for
installation.
If machine is exposed to freezing temperatures after water
circuits have been installed, open waterbox drains and remove all water from cooler and condenser. Leave drains open
until system is filled.
Rigging the Machine — The 19XR machine can be
rigged as an entire assembly. It also has flanged connections
that allow the compressor, cooler, and condenser sections to
be separated and rigged individually.
RIG MACHINE ASSEMBLY — See rigging instructions on
label attached to machine. Also refer to rigging guide
(Fig. 3 and 4), physical data in Fig. 5, and Tables 1-8B. Lift
machine only from the points indicated in rigging guide. Each
lifting cable or chain must be capable of supporting the entire weight of the machine.
Lifting machine from points other than those specified
may result in serious damage to the unit and personal
injury. Rigging equipment and procedures must be adequate for machine weight. See Fig. 3 and 4 for machine weights.
NOTE: These weights are broken down into component sections for use when installing the unit in
sections. For the complete machine weight, add all component sections and refrigerant charge together. See

NOTE: Weight for NIH 2-Pass Cover, 150 psig is included in the heat exchanger weights shown in Table 6.
NOTE: If the cooler and condenser vessels must be separated, the heat exchangers should be kept level by placing a
support plate under the tube sheets. The support plate will
also help to keep the vessels level and aligned when the vessels are bolted back together.
NOTE: Wiring must also be disconnected. Label each wire
before removal (see Carrier Certified Prints). In order to disconnect the starter from the machine, remove wiring for the
oil pump, oil heater, control wiring at the power panel, and
the main motor leads at the starter lugs.
Remove all transducer and sensor wires at the sensor. Clip
all wire ties necessary to pull heat exchangers apart.
To Separate Cooler and Condenser:
1. Place a support plate under each tube sheet to keep each
vessel level (Fig. 6, Item 6).
2. Cut the refrigerant motor cooling line at the location shown
(Fig. 6, Item 7).

To Rig Compressor
NOTE: The motor end of the 19XR compressor is heavy
and will tip backwards unless these directions are followed:
1. Cut two 4 in. × 6 in. wooden beams to the same length
as the compressor.
2. Drill holes into the beams and bolt them to the base of
the compressor.
Additional Notes
1. Use silicon grease on new O-rings when refitting.
2. Use gasket sealant on new gaskets when refitting.
3. Cooler and condenser vessels may be rigged vertically.
Rigging should be fixed to all 4 corners of the tube sheet.
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 ACCESSORY ISOLATION (if required) — Uneven floors or other considerations may dictate the use of
accessory soleplates (supplied by Carrier for field installation) and leveling pads. Refer to Fig. 10 and 12.
Level machine by using jacking screws in isolation sole-
plates. 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.
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 in-
structions, before starting machine.
5. Remove jacking screws from leveling pads after grout has
hardened.

1. If relief devices are 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.

field-installed starter (Fig. 28 and 29).
Unit Mounted, Factory-Installed Starter— Attach power leads
by connecting them from inside the starter cabinet to the line
side circuit breaker terminals. See Fig. 26 and 28. Machines
with electro-mechanical starters (wye-delta) will have a top
hat shipped with the machine if the RLA (rated load amps)
is greater than 935 amps. If the machine is equipped with a
solid-state starter, a top hat is provided if the RLA exceeds
740 amps. The top hat is shipped in the knocked-down position and must be assembled and installed on top of the starter
cabinet, over the line side circuit breaker. During assembly,
remove the access plate and use it as the cover piece of the
top hat. The top hat provides additional wire bending space
to attach line side power leads to the circuit breaker within
the starter.
IMPORTANT: Be sure to ground the power circuit in
accordance with the National Electrical Code (NEC),
applicable local codes, and job wiring diagrams. Also,
make sure correct phasing is observed for proper
rotation.

Free-Standing, Field-Installed Starter — Assemble and install compressor terminal box in desired orientation, and cut
necessary conduit openings in conduit support plates. See
Fig. 27 and 29. 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.
Installer is responsible for any damage caused by improper
wiring between starter and compressor motor.
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.
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), obtain insulation
material from machine shipping package consisting of 3 rolls
of insulation putty and one roll of vinyl tape.
1. Insulate each terminal by wrapping with one layer of insulation putty.
2. Overwrap putty with 4 layers of vinyl tape.
High Voltage Units — High-voltage units require special terminal preparation. Follow local electrical codes for highvoltage installation. Vinyltape is not acceptable; ahigh voltage
terminal method must be used.
Connect Power Wires to Oil Pump Starter — See Fig. 30.
Connect power wires to oil pump starter mounted in machine power panel. Use separate fused disconnect or circuit
breaker as shown on job wiring diagrams and Fig. 30. Check
that power supply voltage agrees with oil pump voltage. Follow correct phasing for proper motor rotation.
Do not punch holes or drill into the top surface of the

3.5 Voltage selector switch in machine power panel is factory set for 115 v
control power source. When 230 v control power source is used, set switch
to 230 v position.
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.
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.
IV. POWER WIRING BETWEEN STARTERAND COMPRESSOR MOTOR
4.0 Low voltage (600 v or less) compressor motors have (6)3⁄4in. terminal
studs (lead connectors not supplied by Carrier). Either 3 or 6 leads
must be runbetween compressormotor andstarter,depending ontype
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
betweenterminals is2
15
⁄16inches.Compressor motorstarter must have
nameplate stamped as 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&3inoneconduit, and those to 4,5&6in
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 NationalElectrical Code (NFPA-70)andapplicablecodes. Means forgrounding compressor motor is a pressure connector for No. 4 to 500 MCM

NOTES:
I. GENERAL
1.0 Starters shall be designed and manufactured in accordance with
Carrier Engineering Requirement Z-375.
1.1 All field-supplied conductors, devices, field-installation wiring, and termination of conductors and devices must be in compliance with all applicable codes and job specifications.
1.2 The routing of field-installed conduit and conductors and the location
of field-installed devices must not interfere with equipment access or
the reading, adjusting, or servicing of any component.
1.3 Equipment, installation, and all starting and control devices must comply with details in equipment submittal drawings and literature.
1.4 Contacts and switches are shown in the position they would assume
with the circuit deenergized and the chiller shut down.
1.5 WARNING
— Do not use aluminum conductors.
1.6 Installer is responsible for any damage caused by improper wiring between starter and machine.
II. POWER WIRING TO STARTER
2.0 Power conductor rating must meet minimum unit nameplate voltage
and compressor motor RLA.
When (3) conductors are used:
Minimum ampacity per conductor = 1.25 x compressor RLA
When (6) conductors are used:
Minimum ampacity per conductor = 0.721 x compressor RLA
2.1 Lug adapters may be required if installation conditions dictatethat conductorsbe sized beyond the minimumampacity required. Contact starter
supplier for lug information.
2.2 Compressor motor and controls must be grounded by using equipment grounding lugs provided inside starter enclosure.
III. CONTROL WIRING
3.0 Field supplied control conductors to be at least 18 AWG or larger.
3.1 Chilled water and condenser water flow switch contacts, optional remote start device contacts, and optional spare safety device contacts
must have 24 vdc rating. Max current is 60 mA; nominal current is
10 mA. Switches with gold plated bifurcated contacts are
recommended.
3.2 Remove jumper wire between 12A and 12B before connecting auxiliary safeties between these terminals.
3.3 Pilot relays can control cooler and condenser pump and tower fan motor contactor coil loads rated 10 amps at 115 vac up to 3 amps at
600 vac. Control wiring required for Carrier to start pumps and towerfan motors must be provided to assure machine protection. If primary
pump and tower fan motor are controlled by other means, also provide
a parallel means for control by Carrier. Do not use starter control trans-
former as the power source for pilot relay loads.
3.4 Do not route control wiring carrying 30 v or less within a conduit which
has wires carrying 50 v or higher or alongside wires carrying 50 v or
higher.
3.5 Voltage selector switch in machine power panel is factory set for
115v control power source. When 230 v control power source is used,
set switch to 230 v position.
3.6 Control wiringcables between starter and powerpanel mustbe shielded
with minimum rating of 600 v, 80 C. Ground shield at starter.
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 For 19XR chillers with free-standing starts, 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
thecompressor motorstarter terminals (LL1 and LL2).Anoutside 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 STARTERAND COMPRESSOR MOTOR
4.0 Low voltage (600 v or less) compressor motors have (6)3⁄4in. terminal
studs (lead connectors not supplied by Carrier). Either 3 or 6 leads
must be runbetween compressormotor andstarter,depending ontype
of motor starter employed. If only 3 leads are required, jumper motor

Connect Power Wires to Oil Heater Contactor — Connect
control power wiring between the oil heater contactor terminals and terminals LL1 and LL2 on the field wiring strip
in the compressor motor starter. Refer to Fig. 31 and wiring
label on the machine 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 transfomer secondary terminals produces input level voltage at the transformer primary terminals.
Connect Wiringfrom Starter to Power Panel — Connect control wiring from main motor starter to the machine power
panel.All control wiring must use shielded cable. Also, connect the communications cable. Refer to the job wiring diagrams for cable type and cable number. Make sure the control circuit is grounded in accordance withapplicable electrical
codes and instructions on machine control wiring label.
CARRIER COMFORT NETWORK INTERFACE — The
Carrier Comfort Network (CCN) communication bus wiring
is supplied and installed by the electrical contractor. It consists of shielded, 3-conductor cable with drain wire.
The system elements are connected to the communication
bus in a daisy chain arrangement. The positive pin of each
system element communication connector must be wired to
the positive pins of the system element on either side of it.
The negative pins must be wired to the negative pins. The
signal ground pins must be wired to the signal ground pins.
See Fig. 24 for location of the CCN network connector
(COMM1) on the processor module.
NOTE: Conductors and drain wire must be 20 AWG
(American WireGage) minimum stranded, tinned copper. Individual conductors must be insulated with PVC, PVC/
nylon, vinyl, Teflon,or polyethylene.An aluminum/polyester
100% foil shield and an outer jacket of PVC, PVC/nylon,
chrome vinyl, or Teflon with a minimum operating temperature range of −4 F to 140 F (−20 C to 60 C) is required. See
table below for cables that meet the requirements.
MANUFACTURER CABLE NO.
Alpha 2413 or 5463
American A22503
Belden 8772
Columbia 02525
When connecting the CCN communication bus to a system element, a color code system for the entire network is
recommended to simplify installation and checkout. The following color code is recommended:
SIGNAL TYPE
CCN BUS CONDUCTOR
INSULATION COLOR
COMM1 PLUG
PIN NO.
+ Red 1
Ground White 2
− Black 3
If a cable with a differentcolor scheme is selected, a similar color code should be adopted for the entire network.
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. 25. If the communication bus cable exits from one building and enters another, the shields must be connected to ground
at the lightening suppressor in each building where the cable
enters or exits the building (one point only).
To connect the 19XR chiller to the network, proceed as
follows (Fig. 24 and 25):
1. Cut power to the PIC 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.
6. Insert and secure the WHITE wire to Terminal 2 of the
COMM1 plug.
7. Insert and secure the BLACK wire to Terminal 3 of the
COMM1 plug.
8. Mount a terminal strip in a convenient location.
9. Connect the opposite ends of each conductor to separate
terminals on the terminal strip.
10. Cut another CCN wire and strip the ends of the
conductors.
11. Connect the RED wire to the matching location on the
terminal strip.
12. Connect the WHITE wire to the matching location on
the terminal strip.
13. Connect the BLACK wire to the matching location on
the terminal strip.
