Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and
air-conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered
equipment by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the
literature and on the tags, stickers, and labels that are attached to the equipment.

NOTICE
Read this manual thoroughly before operating or
servicing this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required. Your personal safety and the proper
operation of this machine depend upon the strict
observance of these precautions.
The three types of advisories are defined as follows:
Indicates a potentially hazardous situation
which, if not avoided, could result in death or
serious injury.
Indicates a potentially hazardous situation
which, if not avoided, could result in minor or
moderate injury. It could also be used to alert
against unsafe practices.
Indicates a situation that could result in
equipment or property-damage only
accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are
refrigerants that contain Chlorine, Fluorine and Carbon
(CFCs) and those containing Hydrogen, Chlorine,
Fluorine and Carbon (HCFCs). Not all refrigerants
containing these compounds have the same potential
impact to the environment. Trane advocates the
responsible handling of all refrigerants-including
industry replacements for CFCs and HCFCs such as
saturated or unsaturated HFCs and HCFCs.
Important Responsible Refrigerant
Practices
Trane believes that responsible refrigerant practices
are important to the environment, our customers, and
the air conditioning industry. All technicians who
handle refrigerants must be certified according to local
rules. For the USA, the Federal Clean Air Act (Section
608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures. In addition, some states or
municipalities may have additional requirements that
must also be adhered to for responsible management
of refrigerants. Know the applicable laws and follow
them.
This document and the information in it are the

reserves the right to revise this publication at any time,

Factory Warranty Information
Compliance with the following is required to preserve
the factory warranty:
AAllll UUnniitt IInnssttaallllaattiioonnss
Startup MUST be performed by Trane, or an authorized
agent of Trane, to VALIDATE this WARRANTY.
Contractor must provide a two-week startup
notification to Trane (or an agent of Trane specifically
authorized to perform startup).
When a new chiller is shipped and received from our
Trane manufacturing location and, for any reason, it
requires disassembly or partial disassembly, and
reassembly— which could include but is not limited to
the evaporator, condenser, control panel, compressor/
motor, economizer, purge, factory-mounted starter or
any other components originally attached to the fully
assembled unit— compliance with the following is
required to preserve the factory warranty:
•Trane, or an agent of Trane specifically authorized
to perform start-up and warranty of Trane®
products, will perform or have direct on-site
technical supervision of the disassembly and
reassembly work.
•The installing contractor must notify Trane—or an
agent of Trane specifically authorized to perform
startup and warranty of Trane® products—two
weeks in advance of the scheduled disassembly
work to coordinate the disassembly and
reassembly work.
•Start-up must be performed by Trane or an agent of
Trane specifically authorized to perform startup and
warranty of Trane® products.
Trane, or an agent of Trane specifically authorized to
perform start-up and warranty of Trane® products, will
provide qualified personnel and standard hand tools to
perform the disassembly and reassembly work at a
location specified by the contractor. The contractor
shall provide the rigging equipment such as chain falls,
gantries, cranes, forklifts, etc. necessary for the
disassembly and reassembly work and the required
qualified personnel to operate the necessary rigging
equipment.
This Installation, Operation, and Maintenance manual
applies to CenTraVac™ chillers with two different
refrigerant and oil systems:
•R-123 and OIL00022
•R-514A and OIL00334/OIL00335
IImmppoorrttaanntt:: Verify proper refrigerant and oil for your
chiller before proceeding!
The information and procedures in this document are
to facilitate unit disassembly for clearance and accessreasons during the installation process.
The understanding is that the chiller has what is
referred to as the “compressor doweling option” or
“separable shell option” (which includes compressor
doweling). Compressor doweling sets up the
compressor for removal. The separable shell option
includes a bolt together design between the evaporator
and condenser and allows the shells to be separated in
the field.
IImmppoorrttaanntt:: These procedures do NOT apply to units
that have been installed and electrical
supply wiring has been completed.
•Protect all internal components from exposure to
elements, which could contaminate or corrode
chiller components
•Chiller reassembly
•Replace all gaskets with new gaskets or O-rings and
sealing compound; the contractor should assist a
qualified Trane Technician with this responsibility

Introduction
The disassembly and reassembly procedures described
in this manual should be performed only on chillers
that have been ordered with this shell option. The
process is to be initiated by experienced service
technicians. Contact your local Trane Service office for
assistance if required.
This section discusses a typical disassembly process.
Proper lifting techniques vary based on mechanical
room layout.
•It is the responsibility of the person(s) performing
the work to be properly trained in the safe practice
of rigging, lifting, securing, and fastening the
components involved.
•It is the responsibility of the person(s) providing
and using the rigging and lifting devices to inspect
these devices to ensure they are free from defect
and are rated to meet or exceed the published
weights.
•Always use rigging and lifting devices in
accordance with the applicable instructions for such
devices.
NNoottee:: Additional gaskets and O-rings are shipped with
the chiller when compressor doweling and/or
separable shells are selected.
Before separating shells, remove the purge, the
compressor, and the various unit mounted sensors
(frame LLIDs) as indicated. If possible, the best method
20
CVHE-SVN04M-EN
Page 21
DDiissaasssseemmbbllyy
is to remove the sensor and carefully coil the wire after
labeling the device and its location to aid in
reinstallation. All sensors connect to the buss wiring
with a universal plug. This allows easy disconnection
and reconnection of the sensors.
Reassemble the purge unit in reverse order when the
process is complete.
Figure 5. Example purge unit
Figure 6. Purge unit detail
NNoottee:: Purge unit may appear slightly different than
example shown here.
To remove the purge assembly from the top of the
condenser:
1. Isolate the purge unit from the condenser shell by
closing the vapor and liquid line valves.
2. Disconnect and mark all piping and wiring attached
to the purge unit. Sand all paint off at points and
use a tubing cutter where cuts are to be made. See
Figure 5, p. 21, and Figure 6, p. 21.
3. Remove the fasteners connecting the purge unit
base to its mounting bracket.
4. Two people will be needed to lift purge unit clear of
the chiller. Refer to Table 10, p. 18 for purge unit
weight. Store the purge unit in a clean dry area.
Figure 7, p. 22 through Figure 10, p. 22 show factory-
installed compressor doweling. If components are not
factory doweled, doweling must be installed before
proceeding. Contact the local Trane Service Company.
Figure 7. Compressor dowelings on casings
Figure 9. Compressor doweling on condenser
discharge flange (these are standard on all CenTraVac
chillers)
1. Disconnect the inlet vane linkage.
a. Disconnect the rod end bearings connecting the
inlet vane operator levers to the guide vane
links as in Figure 10, p. 22 and Figure 11, p. 23.
Leave the rod end bearing connecting the guide
vane links to the main drive levers attached.
NNoottee:: Do not rotate the rod end bearings on the
shaft as this will alter the inlet guide vane
operations and compressor performance.
b. Remove the cotter pin securing the vane
operator stud to the vane drive and slide the
stud out of the main drive. See Figure 12, p. 23.
c. Remove the hex head bolts securing the vane
drive support assemblies to the compressor
castings and remove the main drive and inlet
vane levers from the compressor as a unit. See
Figure 12, p. 23.
d. Remove the hex head bolts securing the vane
drive support assemblies to the compressor
castings and remove the main drive and inlet
vane levers from the compressor as a unit. See
Figure 12, p. 23.

NNoottee:: Cover all open connections to avoid
prolonged exposure of oil to humid air.
Remove oil if a chiller is kept in a
disassembled condition for an extended time.
Figure 13. Lubrication system supply, drain, and
vent lines
2. Disconnect all external vent lines, motor cooling
supply and drain lines, and oil supply and drain
lines which are connected to the compressor and
compressor motor. Sand all paint off the points
where cuts are to be made. Use a tubing cutter to
ensure that cuts are smooth and square. Figure 13,
p. 23 and Figure 14, p. 23 illustrate these lines.
Couplings will be used to reconnect the lines when
Figure 14. Lubrication system motor cooling lines
3. Remove the control panel if necessary. Also,
disconnect and remove the unit mounted starter, if
so equipped. See “Control Panel Removal,” p. 27
for instructions.
CVHE-SVN04M-EN

DDiissaasssseemmbbllyy
4. Remove the economizer vent pipe flange bolts at
the compressor connection. See “Economizer
5. Only Trane Service Agencies have access to the
certified lifting plates to allow safe compressor/
motor assembly removal. Before removing the
compressor/motor assembly, consult with a rigging
specialist. Employ rigging specialist procedures
when removing the compressor motor/assembly.
There are two styles of suction elbows, a 90° elbow
and a three-piece elbow, that can be found in the
disassembly process.
NNoottee:: Apply oil on steel compressor internal parts
for rust prevention. Only a thin layer of oil is
necessary. Avoid over applying. Use POE
break-in oil.
a. Use a sling to support the 90° elbow style
suction elbow. Apply slight lifting pressure.
b. Three-piece suction elbows have a lifting tab.
You will need a lifting clevis to remove the
elbow. A Crosby screw pin shackle, model S209, stock number 1018482 with a 5/8-in. pin is
acceptable as shown in Figure 15, p. 24.
Figure 15. Lifting clevis on the suction elbow
lifting tab (three-piece elbow style)
c. Remove the bolts from the control mounting
bracket on the back of the control panel.
d. Remove the suction elbow bolts at the
compressor and evaporator connections..
e. Lift the suction elbow from the chiller being
careful to avoid damage to flange surfaces.
f. Install protective covers on the evaporator and
compressor connections. Plastic secured with
duct tape makes an adequate cover if no heavy
objects are set on the openings.
7. Support the compressor/motor assembly as
indicated by the rigging specialist (see Step 5). Do
not lift the assembly; instead support the assembly
to prevent it from slipping as the compressor foot
and discharge connection flange bolts are removed.
NNoottee:: Plan ahead where the compressor will be
secured. Build a suitable plant form to support
the assembly before the lift. Gently set
compressor onto prefabricated pre-formatted
support. Use care not to damage the cast
compressor foot (see foot in Figure 8, p. 22).
Similarly, avoid damage to the discharge volute
flange (see discharge flange in Figure 9, p. 22).
8. Remove the compressor/motor assembly. Remove
the locating dowel pins from the compressor foot
and discharge flange connections as shown in
Figure 8, p. 22 and Figure 9, p. 22. To remove the
dowel pin, first remove the nut on the dowel pin,
place a bushing on the pin, and then reinstall the
nut. As the nut is tightened, the dowel pin should
pull out of its hole; at this point, remove the
compressor/motor assembly.
Compressor Motor Mount
Disassembly
If additional vertical clearance is required, the height of
the compressor motor mount can be reduced. Use the
following procedure:
1. Before cutting off the motor mount, first fabricate a
1/4-inch steel backing plate.
a. Cut the backing plate to shape and clamp it to
the motor mount.
b. Drill four 1/4-inch holes through the motor
mount and the backing plate as shown in Figure
16, p. 25. These holes with bolts or roll pins
installed will be used to align the components
during reassembly.
c. Remove the backing plate.
2. Using an oxyacetylene torch, cut the mount as
shown in Figure 16, p. 25.
During reassembly, use the backing plate with bolts or
roll pins to locate the pieces properly. After the pieces
are located, Trane recommends welding the mount and
backing plate in place.
1. Support the weight of the economizer with a
movable floor jack. Do not lift the economizer;
simply support it. Economizer weights are provided
in Table 10, p. 18; also see submittal. It is
25
Page 26
DDiissaasssseemmbbllyy
recommended that larger size economizers be lifted
using overhead rigging.
2. If the unit has insulation, remove the insulation and
loosen the bolts on the condenser liquid line flange.
See Figure 17. Do not remove the bolts at this time.
Cut the motor cooling drain line(s) if present and
cut entering and leaving 5/8 inch OD copper oil
cooler lines. Refer to Figure 17, p. 26.
NNoottee:: Take care to avoid damage to angle valves
during handling and transfer of economizer.
3. Loosen the bolts on the evaporator liquid line
flange. This connection is near the bottom of the
evaporator. See Figure 17, p. 26. Do not remove the
bolts at this time.
4. Economizers are connected to the condenser shell
via a bolted flange. See Figure 22, p. 29. Remove
the bolts at this flanged connection.
5. Loosen the economizer vent pipe bolts that secure
the vent pipes to the compressor interstage
castings (unless the compressor has already been
removed to gain vertical clearance.)
6. Secure economizer with appropriate rigging.
7. Remove the bolts from the condenser and
evaporator liquid line connection flanges. Adjust
the floor jack as necessary to support the weight of
the economizer.
8. Remove the economizer vent pipe flange bolts to
loosen the economizer. When the bolts are free,
back the economizer away from the chiller. The
economizer may tend to rotate off the jack towards
the chiller. Be prepared to offset the rotation.
9. Remove the economizer orifice plates and mark
them so they are reinstalled in their original
position. The orifice with the greatest number of
holes is to be located between the economizer and
the evaporator. The orifice with fewer holes is to be
located between the condenser and economizer.
10. Move the economizer away from the chiller and set
it on a pallet. Cover all openings to prevent the
entry of foreign material into the economizer,
condenser and compressor.
11. Use the reverse order to reassemble the
economizer on the chiller. Be sure to install new
gaskets at the appropriate joints.
12. Torque all bolts to specifications. Consult with your
Trane service group for specific torques for your
economizer design.
Use the following steps to remove the control panel if
additional horizontal clearance is required.
1. Mark and disconnect incoming wiring to the control
panel.
2. Remove the bolts from the bottom of the panel
which secure the panel to the lower mounting
bracket.
3. Loosen the bolts on the back of the panel which
secure the panel to the top (suction elbow)
mounting bracket. See Figure 18, p. 27.
Figure 18. Control panel mounting bracket
Unit-mounted Starter Removal
Additional horizontal and vertical clearances may be
obtained by removing the unit-mounted starter on
chillers so equipped. See Figure 19, p. 27 and Figure
20, p. 27.
NNoottee:: Unless otherwise stated, lift only vertically on
starter-provided devices. Refer to all starterrelated manuals prior to lifting. If needed, use a
spreader bar to avoid angles in chains and
reduce required lifting height clearance.
Figure 19. Unit-mounted starter
Figure 20. Starter mounting bracket
4. Two people will be needed to lift the panel clear of
the chiller. Refer to Table 10, p. 18 for control panel
weight. Steady the panel as the top retaining bolts
are removed. Then lift the panel clear. Store the
panel in a clean dry area.
5. Use the reverse order to reassemble the control
panel.
CVHE-SVN04M-EN
The following procedure assumes the chiller is new
and has never been installed and therefore there is no
electrical power connected to the chiller. If there is
power to the unit, follow proper lockout/tagout
procedures, and any other applicable safety
regulations regarding electric power.
1. Mark and disconnect the power wiring at the
compressor motor terminal lugs inside the starter
panel.
2. Mark and disconnect control wiring entering the
starter panel.
3. Remove the bolts securing the bottom of the starter
to the brackets on the evaporator.
4. To move the starter panel away from the chiller, it is
recommended that a fork truck be used. Position
the truck so that it is ready to take up the weight of
the starter panel. The panel is top-heavy and must
be adequately secured before moving. Refer to
5. Loosen the bolts which hold the starter to the flange
on the motor. Steady the starter panel as the
retaining bolts are removed because the panel will
tip forward. See Figure 19, p. 27.
6. Support the weight of the starter panel with the fork
truck and carefully remove the starter panel from
the chiller. Store the panel in a clean dry area free of
any corrosive agents. When ready, reassemble the
panel on the chiller in reverse order.
Condenser/Evaporator
Disassembly
After the compressor assembly has been removed on
separable shell units, the condenser and evaporator
shells can be taken apart at flanged connections to
reduce the horizontal clearance required for the chiller
installation.
NNoottee:: Brace condenser legs to prevent flexing. Do not
move the condenser horizontally without bracing
legs.
1. Ensure that condenser and evaporator shells are
securely supported on level ground. If not, shim
under the bases.
2. Support the condenser with rigging using the lifting
holes on the tube sheets. See Figure 21, p. 29. Do
not lift the shell, simply support it to avoid slipping
as the bolts are removed from the connecting
flange.
28
CVHE-SVN04M-EN

Figure 21. Separable shell unit (end view)
3. Remove the bolts from the flanges connecting the
evaporator tube sheet and condenser shell support
(see Figure 22, p. 29). Then remove the bolts from
the flanges connecting the shells.
NNoottee:: Some small shell combinations do not have
flanged connections between shells.
4. Remove the two dowel pins located in the flange on
each end of the shell tube sheet connections and lift
the condenser clear of the evaporator.
5. Reassemble the evaporator and condenser shells in
the reverse order.
6. Torque all bolts to specifications listed in Table 13,
p. 32.
Figure 22. Separable shell unit (flange connection)
Disassembly of Chillers with
Options
Heat Recovery
Use the following steps when disassembling chillers
with auxiliary or heat recovery condenser shells to
reduce the vertical clearance required for the chiller
installation.
1. Support the auxiliary or heat recovery condenser
with rigging using the lifting holes on the tube
sheets. Do not lift the shell; simply support it to
avoid slipping as the bolts are removed from the
connecting flanges.
2. Remove the bolts from the flanges on the
interconnecting piping and flanges connecting the
auxiliary heat recovery condenser and condenser
tube sheets.
3. Remove the bolts from the flanges on the
interconnecting piping and the flanges connecting
the shells.
4. Lift the condenser clear of the unit.
5. Reassemble the condenser in the reverse order.
Install new gaskets at the appropriate joints.
6. Torque all bolts to torque specifications listed in
Table 13, p. 32.
29
Page 30
DDiissaasssseemmbbllyy
7. Remove and coil up sensors.
Free Cooling
Use the following steps on free cooling units to reduce
the vertical clearance required for chiller installation.
1. Support the piping and free cooling valve between
the condenser and suction elbow with rigging
similar to that used for removing the suction elbow.
Do not lift the piping; simply support it to avoid
slipping as the bolts are removed from the
connecting flanges. (Typical rigging for lifting the
suction elbow can be seen in Figure 15, p. 24.
2. Remove the bolts from the flanges.
3. Lift the piping clear of the unit.
4. Reassemble the piping in the reverse order. Install
new gaskets at the appropriate joints.
5. Torque all bolts to torque specifications listed in
It is important to remove used O-rings and gaskets and
clean joints before reassembling the compressor with
new O-rings and gaskets. All necessary replacement Orings and gaskets are supplied by the factory when the
compressor doweling or separable shell options are
ordered.
Use the following procedure to reattach the
compressor/motor assembly to the chiller.
1. Remove the protective covers on all compressor,
condenser, and evaporator connections. Clean all
mating surfaces using Loctite® “Chisel” cleaner or
CRC® Industrial Gasket Remover. Completely
remove old sealing compound from O-ring
grooves. Use Loctite “N” primer for final surface
preparation.
2. Refer to CTV-SB-66F (General Service Bulletin:CenTraVac O-Ring and Flange Sealant), or the most
recent version, for proper installation of gaskets, ORings, and Loctite sealant. Install a new O-ring on
the compressor discharge connection mating
surfaces. Use Loctite 515 “Gasket Eliminator” to
lubricate the O-ring and provide additional sealing.
This is the only sealing compound recommended
by Trane for use on O-ring joints. To use this
sealing compound, apply a light bead
(approximately 1/8-in. in diameter) to the O-ring
groove, insert the O-ring and then apply a light
bead to the O-ring. Also apply a 1/8-in. bead of
sealing compound between the O-ring groove and
the bolt hole circle. The parts can now be
assembled.
3. Lift the compressor/motor assembly into place.
Insert the bolts in the compressor foot and
discharge flange connections. Before tightening
any of these bolts, reinstall the dowel pins in the
compressor foot and discharge flange.
4. Tighten the compressor foot and discharge flange
bolts. See Table 13, p. 32 for bolt torque
specifications.
5. Install and tighten the motor mount bolts. See
Table 13, p. 32 for bolt torque specifications.
6. Remove the lifting equipment.
7. Set up dial indicators on the compressor end of the
compressor/motor assembly. See Figure 23, p. 31.
The dial indicators are used to monitor horizontal
and vertical movement of the compressor/motor
assembly when the suction elbow retaining bolts
are tightened. Support the dial indicators from the
condenser or from a floor stand.
Figure 23. Suction elbow flange bolts
8. Clean the suction elbow flange surfaces and O-ring
grooves per Step 1. For the evaporator to suction
elbow joint, use Loctite 515 per Step 2. For the
suction elbow to compressor joint, use 1/8-in.
GORE-TEX® Joint Sealant placed approximately 1/
8-in. in board of the O-ring groove. This is used in
addition to the O-ring. As an option, Loctite 515
may be used in place of GORE-TEX. However, great
care must be taken to prevent the sealant from
entering the first stage IGV housing. Refer to CTVSB-66F (General Service Bulletin: CenTraVac O-Ringand Flange Sealant), or the most recent version.
9. Lift the suction elbow into place using a sling or
chain-fall hoist.
10. Install the suction elbow retaining bolts.
11. Tighten the retaining bolts only “hand tight”.
Tighten two retaining bolts, 180 degrees apart at
the compressor connection. Then tighten two bolts,
180 degrees apart at the evaporator connection.
Alternate between connections until all retaining
bolts are tight. Monitor the dial indicators to ensure
that there is no more than 0.010 inches of
compressor movement. If there is more movement
than this, loosen all of the bolts, “zero” the dial
indicators and repeat the procedure. Figure 23, p.
31 illustrates the bolt tightening sequence.
12. Reconnect the economizer vent pipes. Be sure to
clean the mating surfaces and use new gaskets on
the connections. Tighten the flange bolts just
enough so that the gasket material just begins to
extrude from between the flanges.
