Start-Up and Service 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 prop-
erty 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 building.
Outlet from rupture disc or relief valve must be vented out-
doors in accordance with the latest edition of ANSI/ASHRAE
15 (American National Standards Institute/American Society
of Heating, Refrigerating and Air-Conditioning Engineers)
(Safety Code for Mechanical Refrigeration). The accumula-
tion 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 functioning before operating any machine.
RISK OF INJURY OR DEATH by electrocution. High volt-
age is present on motor leads even though the motor is not run-
ning when a solid state or inside-delta mechanical starter is
used. Open the power supply disconnect before touching
motor leads or terminals.
WARNING
Failure to follow these procedures may result in personal
injury or death.
DO NOT USE TORCH to remove any component. System
contains oil and refrigerant under pressure.
To remove a component, wear protective gloves and goggles
and proceed as follows:
a. Shut off electrical power to unit.
b. Recover refrigerant to relieve all pressure 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 produces toxic gases.
d. Cut component connection tubing with tubing cutter and
remove component from unit. Use a pan to catch any oil
that may come out of the lines and as a gage for how
much oil to add to the system.
e. Carefully unsweat remaining tubing stubs when neces-
sary. Oil can ignite when exposed to torch flame.
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 con-
trol 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
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 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 neces-
sary 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 refriger-
ant to the machine. The introduction of the wrong refrigerant
can cause machine damage or malfunction.

WARNING
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.
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 mecha-
nism. 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.
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 STARTER, TOWER FAN, OR PUMPS.
Open the disconnect ahead of the starter, tower fan, and
pumps. Shut off the machine or pump before servicing equip-
ment.
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 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.
DO NOT re-use compressor oil or any oil that has been
exposed to the atmosphere. Dispose of oil per local codes and
regulations.
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 prevent oil con-
tamination when timely repairs cannot be completed.

(19XRV, 380-480V)
WARNING
DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input
power, wait five (5) minutes for the DC bus capacitors to
discharge and then check the voltage with a voltmeter rated
for the DC bus voltage to ensure the DC bus capacitors are
discharged before touching any internal components. Fail-
ure to observe this precaution could result in severe bodily
injury or loss of life.
An isolated multimeter will be needed to measure DC bus
voltage and to make resistance checks. The drive’s DC bus
capacitors retain hazardous voltages after input power has
been disconnected.

START-UP
Initial start-up of the VFD should be completed by a trained
technician certified by Eaton and Carrier as a commissioner for
the LCX9000 VFD. Proper commissioning forms should be
completed for submission to Eaton. Submission is to be com-
pleted at www.eaton.com/vfdcommissioningreport. The entire
VFD parameter set should be collected at start-up for possible
use later in the equipment life-cycle.
Wire Lugs
See Table 3 for wire lug sizes. In the case where the incoming
power wire size does not fit the standard lug, alternate lugs
may be used. Note that lugs rated for a higher current than the
circuit breaker may be used.

DANGER
Internal components and circuit boards of the drive are live
when the drive is connected to incoming power potential.
Coming into contact with this voltage is extremely danger-
ous and will result in severe personal injury or death.
The motor terminals U, V, W and the DC-link/brake resis-
tor terminals B+/R+, R– are live when the drive is connect-
ed to incoming power, even if the motor is not running.
Do not make any connections when the drive is connected
to the incoming power.
After having disconnected the drive, wait until the indica-
tors on the keypad go out (if no keypad is attached see the
indicator through the keypad base). Wait 5 more minutes
before doing any work on drive connections. Do not even
open the cover before this time has expired.
Before connecting the drive to incoming power, make sure
that the switchgear enclosure door is closed.
WARNING
The control I/O-terminals are isolated from the incoming
power potential. However, the relay outputs and other I/O
terminals may have a dangerous control voltage present
even when the drive is disconnected from incoming power.
Coming into contact with this voltage could result in severe
personal injury.
CAUTION
If other than refrigerant cooling is used, before connecting
the drive to incoming power, make sure that the coolant is
circulating and has no leaks.

Commissioning the Unit
The commission procedure is as follows:
1. If the chiller has been stored outdoors, allow at least 24 hours
room temperature stabilization prior to commissioning. En-
sure any condensation that occurs as a result of the ambient
temperature is allowed to evaporate.
2. Enter parameters in the VFD_CONF (PIC III) / UM VFD
Configuration (PIC 6) screen.
3. Install surge suppression devices if required.
4. Review the power wiring and grounding to ensure that it has
been properly connected.
5. Visually examine the inside of the drive enclosure to:
a. Look for signs of corrosion or moisture residue.
b. Remove any dirt or debris.
c. Make sure all vents are clear.
6. Apply power to the drive and take thermal measurements of
the power connections. Do this again before start-up.
7. Measure and record the incoming line voltages Vab,Vbc,
Vca.
Pick the line voltage of the greatest difference from the aver-
age voltage. Subtract the smaller from the larger to get Vdiff.
Voltage imbalance must be 2% or less.
8. Take a final thermal measurement of the termination after fi-
nalizing the installation to ensure all connections are good.
9. If a ground fault occurs, then do the following:
a. Turn off and lock out input power. Wait five minutes.
b. Check for a ground in the motor or motor wiring.
c. Check for damage to wiring insulation and that wiring
is dry.
d. Verify the motor wiring is separated from ground and
there is no connection between phases.
e. Check for failed IGBTs.
10. If an Overcurrent fault occurs, then do the following:
a. Turn off and lock out input power. Wait five minutes.
b. Check for excessive load and verify load limit settings
on the ICVC (PIC III) or CFGUMVFD (PIC 6)
screen.
c. Check motor and wiring insulation.
d. Check parameter settings on VFD_CONF (PIC III) /
CFGUMVFD (PIC 6) screen.

SERVICE
Troubleshooting the Drive
The drive can display two kinds of error codes on the HMI
called the Alert and Alarm codes. These codes signal a
problem detected during self tuning or drive operation. Alert
and Alarm codes are located in the 19XRV or 23XRV Start-Up,
Operation and Maintenance Instructions.
• A warning message on the HMI is an ALERT.
• The same warning viewed with the Eaton 9000x software
tool is a VFD ALARM.
• A failure resulting in a shutdown is seen as an ALARM on
the ICVC and as a VFD FAULT when viewed with Eaton
9000x software.
CONDITION CODES
CHILLER ALERT = VFD ALARM
CHILLER ALARM = VFD FAULT
For PIC III the ICVC displays the Eaton code in the VFD HIST
screen. Other ICVC screens will display the ICVC codes. For
PIC6 all alert/alarm codes are located under History Alarms.
Eaton codes that do not have a corresponding ICVC code will
appear on the ICVC default and Alarm history screens as code
206 or Alarm code 449 for PIC 6.
CHILLER ALERT CODES — An alert condition is indicated by
a message on the HMI screen. The drive will continue to operate
during the alert condition. Investigate the cause of the alert to
ensure it does not lead to a fault condition. The alert code will
automatically be cleared from the HMI when the condition
causing the alert no longer exists.
CHILLER ALARM CODES — An alarm condition is indicated
by a message on the HMI screen. If an alarm occurs, the drive

TEST EQUIPMENT NEEDED TO TROUBLESHOOT — An
isolated multimeter adequately rated for the DC bus voltage will
be needed to measure DC bus voltage and to make resistance
checks. Note that dedicated troubleshooting test points are not
provided.
VERIFYING THAT DC BUS CAPACITORS ARE DIS-
CHARGED — The drive’s DC bus capacitors retain hazardous
voltages after input power has been disconnected. Perform the fol-
lowing steps before touching any internal components:
1. Turn off and lock out input power. Wait five minutes.
2. Verify that there is no voltage at the drive’s input power ter-
minals.
3. Measure the DC bus potential with a voltmeter while stand-
ing on a non-conductive surface and wearing insulated
gloves (1000 v). Measure the DC bus potential. See Fig. 1.
The voltage between DC+ and DC–, and from each DC ter-
minal to the chassis must be zero before proceeding.
4. Once the drive has been serviced, reapply input power.
HIGH TEMPERATURE ALARMS — Coolant flow
through the cold plate is controlled by an orifice in the refrigerant
line leaving the cold plate. The orifice looks like one of the O-ring
face seal connectors and in fact is used as one of the connections
on the coolant tubing. If the orifice is present and condenser liquid
flow is present, the liquid will flash to cooler temperature at the or-
ifice. This temperature difference is great enough to be easily felt.
MAIN CONTROL BOARD (MCB) COMPONENTS —
Refer to Fig. 6 for the location at the I/O board and relay boards
which are installed in slots A-D. The OPTCC communication
board is installed in slot E. Typical wiring schematics are shown
in Appendix A.
Fig. 6 — Basic and Option Board Connections of the
Control Board
WARNING
DC bus capacitors retain hazardous voltages after input
power has been disconnected. After disconnecting input
power, wait five (5) minutes for the DC bus capacitors to
discharge and then check the voltage with a voltmeter to en-
sure the DC bus capacitors are discharged before touching
any internal components. Failure to observe this precaution
could result in severe bodily injury or loss of life.

Checking Power Modules and Motor Input with
Input Power Off
Use the following procedure to check the drive’s power mod-
ule circuitry with power off:
1. Turn off and lock out input power. Wait five minutes.
2. Verify there is no voltage at the drive’s input power
terminals.
3. Using a voltmeter, check the DC bus potential as described
in Fig.7 to ensure the DC bus capacitors are discharged.
4. Disconnect the motor from the drive.
5. Check all AC line and DC bus fuses.
6. Check motor impedance.
7. Reconnect the motor to the drive.
8. Reapply input power.

Servicing the Drive
REMOVING THE DRIVE FROM THE ENCLOSURE
The weights specified must be taken into consideration when
removing the drive. All lifting equipment and lifting components
(hooks, bolts, lifts, slings, chains, etc.) must be properly sized and
rated to safely lift and hold the weight of the drive while removing
it. The drive weights are as follows:
• Drive weight for CH72: 198 lb
• Drive weight for CH63: 264 lb
• Drive weight for CH74: 617 lb
Frame CH72
Refer to Fig. 8 and 9. Frame CH72 has one drive module
which is mounted horizontally to the bottom surface of the en-
closure. The input end of the module is on the left and the out-
put end is on the right.
To remove the drive:
1. Remove all power cabling from the top power connections
bus bars.
2. Remove all power bussing from the bottom power connec-
tions bus bars.
3. Close refrigerant cooling isolation valves. Remove the two
refrigerant lines (supply and return) from the output end of
the drive.
4. Remove the cabinet center door bracket.
5. Remove the bolts holding the drive chassis to the cabinet.
6. Attach tag lines to the handles to prevent the drive from
swinging as it is lifted free of the cabinet bottom.
7. Connect lifting chains to the handles at the left and right
sides of the drive (as mounted).
8. Lift the drive with the hoist.
To reinstall the drive chassis, reverse the above procedure.
Frames CH63 and CH74 — Refer to Fig. 10.
Frame CH63 has 2 modules on the chassis. The chassis is held
to the two Z brackets by two bolts in each bracket.
Frame CH74 has 3 modules on the chassis. The chassis is held
to the two Z brackets by four bolts in each bracket.
To remove the drive:
1. Remove all power cabling from the top power connections
bus bars.
2. Remove all power bussing from the bottom power connec-
tions bus bars.
3. Close refrigerant cooling isolation valves. Remove the two
refrigerant lines (supply and return) from the bottom of the
drive.
4. Remove the cabinet ceiling and center door bracket.
5. Connect lifting chains to the top two 1.15-in. diam lifting
holes.
6. Lift hoist until chains have slight tension.
7. Loosen and remove bolts that hold the bottom of the drive to
the Z bracket (2 bolts on CH63, 4 bolts on CH74).
8. Loosen the 2 or 4 bolts that hold the top of the drive to the Z
bracket. The drive may drop down a little to rest on the top Z
bracket.
WARNING
To guard against possible personal injury and/or equipment
damage:
1. Inspect all lifting hardware for proper attachment before
lifting drive.
2. Do not allow any part of the drive or lifting mechanism
to make contact with electrically charged conductors or
components.
3. Do not subject the drive to high rates of acceleration or
deceleration while transporting to the mounting location
or when lifting.
Do not allow personnel or their limbs directly underneath the
drive when it is being lifted and mounted.
NOTE: DC terminals are on the input end of the CH72 and CH74
drive modules as shown in Fig. 1. The CH74 drive has 3 modules.
The CH63 drive has 2 modules. The DC bus terminals are located
on the top of the module as shown in Fig. 2 while both the input
(L1, L 2, L3) and output (T1,T 2, T3) terminals are located on the
bottom of the drive.
The DC bus terminals for all modules are connected to each other
(+) to (+) and (–) to (–).
