SAFETY CONSIDERATIONS
Centrifugal liquid chillers are designed to provide safe and reli-
able service when operated within design specifications. When
operating this equipment, use good judgment and safety pre-
cautions 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.
DANGER
Failure to follow these procedures will result in severe per-
sonal injury or death.
DO NOT VENT refrigerant relief devices within a build-
ing. Outlet from rupture disc, relief valve, purge unit, or
fusible plugs must be vented outdoors in accordance with
the latest edition of ANSI/ASHRAE 15 (American Nation-
al Standards Institute/American Society of Heating, Refrig-
erating and Air-Conditioning Engineers) (Safety Code for
Mechanical Refrigeration). The accumulation of refrigerant
in an enclosed space can displace oxygen and cause as-
phyxiation.
PROVIDE adequate ventilation in accordance with ANSI/
ASHRAE 15, especially for enclosed and low overhead
spaces. Inhalation of high concentrations of vapor is harm-
ful 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 breath-
ing. 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 al-
lowable 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 in-
stalled and functioning before operating any machine.
RISK OF INJURY OR DEATH by electrocution. High
voltage is present on motor leads even though the motor is
not running. Open the power supply disconnect before
touching motor leads or terminals and wait for capacitors to
fully discharge.

WARNING
Failure to follow these procedures may result in personal
injury or death.
DO NOT USE TORCH to remove any component. System
contains refrigerant which can be under pressure.
To remove a component, wear protective gloves and gog-
gles and other necessary safety equipment, and proceed as
follows.
a. Shut off electrical power to unit.
b. Recover refrigerant from system using both high-
pressure and low-pressure ports.
c. Traces of vapor should be displaced with nitrogen
and the work area should be well ventilated.
Refrigerant in contact with an open flame pro-
duces toxic gases.
d. Cut component connection tubing with tubing cut-
ter and remove component from unit.
e. Carefully unsweat remaining tubing stubs when
necessary.
DO NOT USE eyebolts or eyebolt holes to rig machine sec-
tions 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, variable frequency drives (VFDs),
or compressors until you are sure ALL POWER IS OFF
and no residual voltage can leak from capacitors.
LOCK OPEN AND TAG electrical circuits during servic-
ing. IF WORK IS INTERRUPTED, confirm that all cir-
cuits are de-energized 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 en-
ters the eyes, IMMEDIATELY FLUSH EYES with water
and consult a physician.
NEVER APPLY an open flame or live steam to a refriger-
ant 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 ILLE-
GAL. 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 re-
frigerant to the machine. The introduction of the wrong re-
frigerant can cause machine damage or malfunction.
Operation of this equipment with refrigerants other than
those cited herein should comply with ANSI/ASHRAE 15
(latest edition). Contact Carrier for further information on
use of this machine with other refrigerants.
BEFORE ADDING INHIBITOR to the unit, be sure to
check the type. Using the wrong type could result in dam-
age to the unit. Factory unit comes supplied with inhibitor.
DO NOT ATTEMPT TO REMOVE fittings, covers, etc.,
with refrigerant in the machine or while machine is run-
ning. Be sure pressure is at 0 psig (0 kPa) before breaking
any refrigerant connection. Note that at 65°F (18°C) the
machine is at near 0 psig (0 kPa) so ensure to properly
check for the existence of refrigerant in the machine.
CAREFULLY INSPECT all relief valves, rupture discs,
and other safety relief devices AT LEAST ONCE A YEAR.
If machine operates in a corrosive atmosphere, inspect the
devices at more frequent intervals.
WARNING
DO NOT ATTEMPT TO REPAIR OR RECONDITION
any relief device when corrosion or build-up of foreign ma-
terial (rust, dirt, scale, etc.) is found within the valve body
or mechanism. Replace the valve or device.
DO NOT install relief devices in series or backwards.
USE CARE when working near or in line with a com-
pressed spring. Sudden release of the spring can cause it
and objects in its path to act as projectiles.
Prior to installing or servicing this equipment ensure that
personal protective equipment (PPE) is worn as required
per OSHA or other local regulations.
For servicing or installing components where there is a risk
of arc flash the technicians must wear personal protective
equipment as identified in NFPA (National Fire Protection
Association) 70E or other local country-specific require-
ments for arc flash protection.
CAUTION
Failure to follow these procedures may result in personal
injury or damage to equipment.
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 VFD, TOWER FAN, OR PUMPS. Open
the disconnect ahead of the VFD, 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 indus-
trial brines, liquid, gases, or semisolids without the permis-
sion of your process control group.
DO NOT LOOSEN waterbox cover bolts until the water-
box has been completely drained.
DOUBLE-CHECK that coupling nut wrenches, dial indica-
tors, 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. Ensure to slope piping way from relief device.
DO NOT re-use compressor purge oil or any oil that has
been exposed to the atmosphere. Dispose of oil and refrig-
erant per local codes and regulations.
DO NOT introduce oil to the refrigerant circuit with refrig-
erant recovery containers, vacuum pump, or other means.
DO NOT leave refrigerant system open to air any longer
than the actual time required to service the equipment. Seal
circuits being serviced and charge with dry nitrogen to pre-
vent contamination when timely repairs cannot be
completed.

INTRODUCTION
General
The 19DV unit is factory assembled, wired, and leak tested. In-
stallation consists primarily of establishing water and electrical
services to the machine. The rigging, installation, field wiring,
field piping, and insulation of waterbox covers are the respon-
sibility of the contractor and/or customer. Carrier has no instal-
lation responsibilities for the equipment. The refrigerant charge
will be installed by the Carrier Start-up Technician during the
start-up process.
Job Data
Necessary information consists of:
• job contract or specifications
• machine location prints
• rigging information
• piping prints and details
• field wiring drawings
• starter manufacturer’s installation details
• Carrier certified print
CHILLER FAMILIARIZATION
Chiller Information Nameplate
The information nameplate is located on the left side of the chiller
control panel. Refer to Fig. 1 for model number identification.
System Components
The main components include the evaporator and condenser
heat exchangers in separate vessels, compressor, refrigerant lu-
brication system, control panel, economizer, VFD, and purge
system.
Evaporator
This heat exchanger (also known as the evaporator) is located
underneath the compressor. The evaporator is maintained at
lower refrigerant temperature/pressure so evaporating refriger-
ant can remove heat from water flowing through its internal
tubes.
Condenser
This heat exchanger operates at a higher refrigerant tempera-
ture/pressure than the evaporator and has water flowing
through its internal tubes in order to remove heat from the re-
frigerant.
Compressor
This component maintains system temperature and pressure
differences and moves the heat carrying refrigerant from the
evaporator to the condenser. The 19DV unit has a back to back
two-stage, direct drive, and economized compressor.
Economizer
This chamber reduces the refrigerant temperature to an intermedi-
ate level between the evaporator and condenser vessels. In the
economizer, vapor is separated from the liquid, the separated va-
por flows to the inlet of the second stage of the compressor, and
the liquid flows into the evaporator. The energy removed from the
vaporized refrigerant in the economizer allows the liquid refriger-
ant in the evaporator to absorb more heat when it evaporates and
benefits the overall cooling efficiency cycle.
VFD
The VFD provides a pulse width modulated signal that results
in variable frequency and voltage to the compressor motor. It is
controlled and monitored from the PIC5 control system.
Purge System
The purge is an independent assembly located under condens-
er. The 19DV chiller system components normally operate in a
vacuum. The purge assembly will automatically remove air
and other non-condensables which may have leaked into the
system to maintain chiller performance. It is controlled through
the PIC5 control system.
PIC5 Touch Screen Panel
This panel is the user interface for controlling the chiller and
has the following functions:
• Chiller operation
• Chiller diagnostic
• Chiller status display
• Chiller parameter configuration
• Open protocol interface to outside building management
system (BMS)
Control Panel
This control panel includes the input and output boards (IOB),
control transformer, relays, contactors, and circuit breakers. It
provides the power distribution and protection to the electrical
component installed on chiller, and has the following functions:
• Communication with PIC5 touch screen
• Communication with purge panel
• Communication with VFD
• Sensor input and outputs
• Actuators control
• Refrigerant pump control
Purge Control Panel
The purge panel includes an input and output boards, control
transformers, relays, and contactors. It provides the power dis-
tribution and protection to the electrical components which in-
stalled in the purge system and has the following functions:
• Communication with PIC5 touch screen
• Sensor input and outputs
• Solenoid valve control
• Control of purge compressor, vacuum pump, heater, and
fan control
Lube Assembly
The lube assembly refers to the filter, strainer and pump pack-
age with automatic valve actuator control located under the
condenser. The objective of the lube assembly is to provides
lubricating liquid refrigerant to the compressor bearings.
INSTALLATION
Step 1 — Receive the Machine
INSPECT SHIPMENT
1. Inspect for shipping damage while machine is still on ship-
ping 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.
CAUTION
Do not open any valves or loosen any connections. The
19DV machine may be shipped with a nitrogen holding
charge. Damage to machine may result.

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 pack-
ages 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
inhibitor charge is placed in the unit before shipment from
the factory.
IDENTIFY MACHINE
The machine model number, serial number, and heat exchanger
sizes are shown on machine identification nameplate (Fig. 1-3).
Check this information against shipping papers and job data.
INSTALLATION REQUIREMENTS
Prior to starting the chiller’s electrical installation, certain re-
quirements should be checked. Input power wire sizes, branch
circuit protection, and control wiring are all areas that need to
be evaluated.
Determine Wire Size Requirements
Wire size should be determined based on the size of the conduit
openings, and applicable local, national, and international
codes (e.g., NEC [National Electric Code]/CEC regulations).
General recommendations are included in the Carrier field wir-
ing drawings. Consult drawing for termination lug sizes.
Fig. 1 — 19DV Refrigeration Machine Nameplate
Conduit Entry Size
It is important to determine the size of the conduit openings in
the enclosure power entry plate so that the wire planned for a
specific entry point will fit through the opening. Do NOT
punch holes or drill into the top surface of any panels. Knock-
outs are provided on the enclosure. The VFD entry plate is de-
signed to be removed before any holes are made to prevent par-
ticulate from entering the cabinet.
Recommended Control and Signal Wire Sizes
The recommended minimum size wire to connect I/O signals to
the control terminal blocks is 18 AWG (American Wire Gage).
Recommended terminal tightening torque is 7 to 9 in.-lb (0.79 to
1.02 N-m).
Required Airflow Clearances
Be sure there is adequate clearance for air circulation around the
enclosure. A 6-in. (152.4 mm) minimum clearance is required
wherever vents are located in an enclosure.
Service Clearances
Verify that there are adequate service clearances as identified
in Fig. 4.
Match Power Module Input and Supply Power Ratings
It is important to verify that building power will meet the input
power requirements of the Machine Electrical Data nameplate in-
put power rating. Be sure the input power to the chiller corre-
sponds to the chiller’s nameplate voltage, current, and frequency
and to the design data sheet provided by the equipment salesman.
Verify all electrical inputs against design data sheets. The VFD
electrical data nameplate is located on the right side of the VFD
enclosure.
PROVIDE MACHINE PROTECTION
Store machine and VFD indoors, protected from construction
dirt and moisture as identified in the long term storage require-
ments. Inspect under shipping tarps, bags, or crates to be sure
that water has not collected during transit. Keep protective
shipping covers in place until machine is ready for installation.

It is important to properly plan before installing a 19DV unit to
ensure that the environmental and operating conditions are sat-
isfactory and the machine is protected. The installation must
comply with all requirements in this document and in the certi-
fied prints.
Operating Environment
Chiller should be installed in an indoor environment where the
ambient temperature is between 40 and 104°F (4 and 40°C) with
a relative humidity of 95% or less, non-condensing. To ensure
that electrical components operate properly, do not locate the
chiller in an area exposed to dust, dirt, corrosive fumes, or exces-
sive heat and humidity.
NOTE: NEMA Type 1 enclosures are constructed for indoor use
to provide a degree of protection to personnel against incidental
contact with the enclosed equipment and to provide a degree of
protection against falling dirt. This type of enclosure does not pro-
tect against water, dust, moisture or airborne contaminants.
Step 2 — Rig the Machine
The 19DV machine can be rigged as an entire assembly. It also
has connections that allow the compressor, evaporator, and
condenser sections to be separated and rigged individually.
RIG MACHINE ASSEMBLY
See rigging instructions on label attached to machine. Refer to
rigging guide (Fig. 5), dimensions in Fig. 4, and physical data
in Tables 1-12. Lift machine only from the points indicated in

RIG MACHINE COMPONENTS
Refer to instructions below, Fig. 6-8, and Carrier Certified
Prints for machine component disassembly.
.
NOTE: If the evaporator, economizer, 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
VFD from the machine, remove wiring between the VFD and the
refrigerant pump, control panel, purge power, 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.
NOTE: All factory units have inhibitor in the lubrication assem-
bly. Both bearing supply and HS float chamber ball valves are shut
at factory to contain the inhibitor (see Fig. 9). Should it be required
to remove the lubrication assembly prior to start-up, do not cut any
low piping without prior removal of inhibitor to avoid spilling on
the floor.
To Separate Evaporator and Condenser:
1. Place a support plate under each tube sheet leg to keep
each vessel level.
2. Cut tubing between high side float chamber and motor/
VFD cooling.
3. Cut tubing between high side float chamber and lube
assembly.
4. Disconnect the compressor discharge pipe.
5. Disconnect bolted connection between the low side float
chamber and the evaporator.
6. Disconnect bolted economizer pipe between economizer
and second stage compressor inlet.
7. Cut tubing between purge and compressor volute.
8. Cut tubing between purge regeneration line and motor
drain.
9. Cover all openings.
10. Disconnect all wires and cables that cross from evaporator
side of the machine to the condenser side.
11. Disconnect the marriage brackets connecting the evapora-
tor and condenser tubesheets (both ends).
To Separate the Compressor from the Evaporator:
1. Unbolt motor drain flange.
2. Unbolt suction pipe flange.
3. Unbolt discharge pipe flange.
4. Cut tubing from purge to compressor volute.
5. Disconnect O-ring face seal from bearing drain (near
motor drain).
6. Cut bearing supply tubing from lube assembly.
7. Cut motor cooling supply line tubing from high side float
chamber.
8. Disconnect inhibitor reclaim line running from compres-
sor to near bottom of evaporator.
9. Disconnect all power and control wires connected to the
compressor.
10. Cover all openings
11. Disconnect compressor motor power cables from VFD to
motor.
12. Unbolt compressor mounting from the evaporator.
Additional Notes
1. Use silicone grease on new O-rings when refitting.
2. Use gasket sealant on new gaskets when refitting.

IMPORTANT: Only a qualified service technician should
perform this operation.
WARNING
Do not attempt to disconnect flanges or tubing while the
machine is under pressure or contains refrigerant. Failure to
relieve pressure can result in personal injury or damage to
the unit.
CAUTION
Before rigging the compressor, disconnect all wires con-
nected to the control panel to avoid damage to electrical
components.

Step 3 — Install Machine Supports
INSTALL STANDARD ISOLATION
Figure 8 shows 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.
Chiller support plates must be level within 1/4-in. (6 mm) from
one end to the other.
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 ap-
plying 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 instruc-
tions, before starting machine.
5. Remove jacking screws from leveling pads after grout has
hardened.

IMPORTANT: Chiller housekeeping pad, anchor bolts, and
attachment points that are designed by others must be in ac-
cordance with all applicable national and local codes.

INSTALL SPRING ISOLATION
Spring isolation may be purchased as an accessory from Carrier
for field installation. It may also be field supplied and installed.
Spring isolators may be placed directly under machine support
plates or located under machine soleplates. See Fig. 11. Consult
job data for specific arrangement. Low profile spring isolation
assemblies can be field supplied to keep the machine at a conve-
nient working height.
Obtain specific details on spring mounting and machine weight
distribution from job data. Also, check job data for methods to
support and isolate pipes that are attached to spring isolated
machines.
NOTE: The springs are designed to support the weight of the
chiller only. Connected piping must be supported independently of
the chiller.
NOTE: It is recommended that any installation other than the
ground floor should have spring isolation for the chiller and piping
vibration isolation.
NOTE: These isolators are not intended for seismic duty, but are
intended to reduce the vibration and noise levels transmitted
from the chiller to the surrounding environment. For installa-
tions adjacent to areas that are sensitive to noise and/or vibration,
use the services of a qualified consulting engineer or acoustics
expert to determine whether these springs will provide adequate
noise/vibration suppression.
