Introduction
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:
WARNING
CAUTION
NOTICE
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.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or
serious injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded
field wiring poses FIRE and ELECTROCUTION
hazards. To avoid these hazards, you MUST follow
requirements for field wiring installation and
grounding as described in NEC and your local/
state/national electrical codes.
WARNING
Personal Protective Equipment (PPE)
Required!
Failure to wear proper PPE for the job being
undertaken could result in death or serious injury.
Technicians, in order to protect themselves from
potential electrical, mechanical, and chemical
hazards, MUST follow precautions in this manual
and on the tags, stickers, and labels, as well as the
instructions below:
•
Before installing/servicing this unit,
technicians MUST put on all PPE required for
the work being undertaken (Examples; cut
resistant gloves/sleeves, butyl gloves, safety
glasses, hard hat/bump cap, fall protection,
electrical PPE and arc flash clothing).
ALWAYS refer to appropriate Material Safety
Data Sheets (MSDS)/Safety Data Sheets
(SDS) and OSHA guidelines for proper PPE.
•
When working with or around hazardous
chemicals, ALWAYS refer to the appropriate
MSDS/SDS and OSHA/GHS (Global
Harmonized System of Classification and
Labelling of Chemicals) guidelines for
information on allowable personal exposure
levels, proper respiratory protection and
handling instructions.
•
If there is a risk of energized electrical
contact, arc, or flash, technicians MUST put
on all PPE in accordance with OSHA, NFPA
70E, or other country-specific requirements
for arc flash protection, PRIOR to servicing
the unit. NEVER PERFORM ANY SWITCHING,
DISCONNECTING, OR VOLTAGE TESTING
WITHOUT PROPER ELECTRICAL PPE AND
ARC FLASH CLOTHING. ENSURE
ELECTRICAL METERS AND EQUIPMENT ARE
PROPERLY RATED FOR INTENDED
VOLTAGE.
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.

WARNING
Follow EHS Policies!
Failure to follow instructions below could result in
death or serious injury.
•
•
All Ingersoll Rand personnel must follow
Ingersoll Rand Environmental, Health and
Safety (EHS) policies when performing work
such as hot work, electrical, fall protection,
lockout/tagout, refrigerant handling, etc. All
policies can be found on the BOS site. Where
local regulations are more stringent than
these policies, those regulations supersede
these policies.
Non-Ingersoll Rand personnel should always
follow local regulations.
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).
Additional Requirements for Units Requiring
Disassembly and Reassembly
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.

General Information
WARNING
Refrigerant May Be Under Positive
Pressure!
Failure to follow instructions below could result in
an explosion which could result in death or
serious injury or equipment damage.
System contains refrigerant and may be under
positive pressure; system may also contain oil.
Recover refrigerant to relieve pressure before
opening the system. See unit nameplate for
refrigerant type. Do not use non-approved
refrigerants, refrigerant substitutes, or nonapproved refrigerant additives.
NOTICE
Equipment Damage!
Mixing refrigerants or oils could result in
equipment damage including bearing damage,
introduction of acids into the chiller, or continuous
purge pump-out in high-head/high ambient
applications.
CenTraVac chillers are manufactured with
different refrigerant/oil systems: 1) chillers using
R-123 refrigerant and OIL00022 compressor oil,
and 2) chillers using R-514A refrigerant and
OIL00334/OIL00335 compressor oil.
Verify proper refrigerant and oil for your chiller
and do NOT mix refrigerants or oils!
Contractor Responsibilities
WARNING
Heavy Objects!
Failure to follow instructions below could result in
component dropping which could result in death
or serious injury, and equipment or property-only
damage.
Loads can shift and become off-center during
shipping. Ensure that components are centered
before lifting and always test lift each component
to verify center of gravity using lifting equipment
rated for the task. Only experienced riggers should
perform unit disassembly/reassembly.
•
Handle/lift and rig equipment
•
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
NOTICE
Compressor Damage!
POE oil is hygroscopic – it absorbs water
directly from the air. This water is nearly
impossible to remove from the compressor oil
and can result in compressor failures.
To prevent POE oil from absorbing water, the
system should not remain open for longer than
necessary. When open, dry nitrogen should
flow through the piping. Only new oil
containers should be used for service and
maintenance. Always use the smallest
container size required for the job
requirements. Always leave the oil container
tightly sealed until time of use. Do not reuse oil
that has been opened.
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
I m p o r t a n t : 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 access
reasons 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.
I m p o r t a n t : These procedures do NOT apply to units
that have been installed and electrical
supply wiring has been completed.

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.
NOTICE
Equipment Damage!
Mixing refrigerants or oils could result in
equipment damage including bearing damage,
introduction of acids into the chiller, or continuous
purge pump-out in high-head/high ambient
applications.
CenTraVac chillers are manufactured with
different refrigerant/oil systems: 1) chillers using
R-123 refrigerant and OIL00022 compressor oil,
and 2) chillers using R-514A refrigerant and
OIL00334/OIL00335 compressor oil.
Verify proper refrigerant and oil for your chiller
and do NOT mix refrigerants or oils!
This Installation Guide applies to CenTraVac™ chillers
with two different refrigerant and oil systems:
•
R-123 and OIL00022
•
R-514A and OIL00334/OIL00335
I m p o r t a n t : Verify proper refrigerant and oil for your
chiller before proceeding!
N o t e : This manual applies to model CDHF, CDHG,
CVHE, CVHF, and CenTraVac chillers.
I m p o r t a n t : Remove the nitrogen charge from the
chiller vessel before starting any
disassembly procedures.
N o t e : Additional gaskets and O-rings are shipped with
the chiller when compressor doweling and/or
separable shells are selected.
WARNING
Heavy Object!
Failure to follow instructions below could result in
unit dropping which could result in death or
serious injury, and equipment or property-only
damage.
Ensure that all the lifting equipment used is
properly rated for the weight of the unit being
lifted. Each of the cables (chains or slings), hooks,
and shackles used to lift the unit must be capable
of supporting the entire weight of the unit. Lifting
cables (chains or slings) may not be of the same
length. Adjust as necessary for even unit lift.
NOTICE
Equipment Damage!
I m p o r t a n t : New units that have been factory run-tested
contain residual refrigerant; vent discharge
outdoors.
Failure to remove the strain relief with the sensor
could result in equipment damage.
Do NOT attempt to pull sensor bulb through the
strain relief; always remove the entire strain relief
with the sensor.
Check to make sure there is a positive pressure holding
charge.
Wiring Disassembly
N o t e : New units ship with a 5 psig (34.5 kPag) dry
nitrogen holding charge at nominal 72°F (22°C).
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

NOTICE
Compressor Damage!
Failure to follow instructions below could cause
the internal components to shift which could
result in serious compressor damage upon
starting the unit.
The compressor motor assembly must not be
removed from the chiller unless special doweling
has been installed at the factory. Doweling must
be installed to prevent the interstage casings from
shifting. If the compressor/motor assembly is
lifted without doweling installed, the internal
alignment may shift. It would then be necessary to
disassemble and then reassemble the compressor
making sure that all internal clearances and
specifications are proper. If doweling is not
factory installed, and it is necessary to install
doweling, contact the local Trane Service
Company. The compressor discharge flange and
mounting foot are also doweled at the factory to
provide proper alignment during reassembly.
Figure 7, p. 22 through Figure 10, p. 22 show factoryinstalled compressor doweling. If components are not
factory doweled, doweling must be installed before
proceeding. Contact the local Trane Service Company.

6. Remove the suction elbow.
There are two styles of suction elbows, a 90° elbow
and a three-piece elbow, that can be found in the
disassembly process.
N o t e : 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.

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.
NOTICE
Equipment Damage!
Failure to follow instructions below could result in
equipment damage.
The cast iron foot of the compressor and the
discharge flange of the volute can be broken easily
if rough handling of the compressor/motor
assembly is allowed. Take great care to prevent
this breakage when removing the compressor/
motor assembly and setting it down, or when
moving it laterally on the floor (e.g., on rollers,
etc). Take extra care to gently sit the compressor/

capacitors before servicing could result in death or
serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper
lockout/tagout procedures to ensure the power
cannot be inadvertently energized. For variable
frequency drives or other energy storing
components provided by Trane or others, refer to
the appropriate manufacturer’s literature for
allowable waiting periods for discharge of
capacitors. Verify with a CAT III or IV voltmeter
rated per NFPA 70E that all capacitors have
discharged.
For additional information regarding the safe
discharge of capacitors, see PROD-SVB06*-EN.
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
Table 12, p. 19 for starter weights.

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.
Set Up Dial Indicator
to Read Vertically
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.
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-Ring
and Flange Sealant), or the most recent version.
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.
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.
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

9. Lift the suction elbow into place using a sling or
chain-fall hoist.
10. Install the suction elbow retaining bolts.
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.

WARNING
Explosion Hazard and Deadly Gases!
Failure to follow all proper safe refrigerant
handling practices could result in death or serious
injury.
Never solder, braze or weld on refrigerant lines or
any unit components that are above atmospheric
pressure or where refrigerant may be present.
Always remove refrigerant by following the
guidelines established by the EPA Federal Clean
Air Act or other state or local codes as appropriate.
After refrigerant removal, use dry nitrogen to
bring system back to atmospheric pressure before
opening system for repairs. Mixtures of
refrigerants and air under pressure may become
combustible in the presence of an ignition source
leading to an explosion. Excessive heat from
soldering, brazing or welding with refrigerant
vapors present can form highly toxic gases and
extremely corrosive acids.
Except as noted in the following, braze with the
following filler metals:
•
Braze all copper-to-copper joints with A.W.S. BcuP6 filler metal.
•
Braze all copper-to-brass joints with A.W.S. BcuP-6
filler metal using white or black brazing flux.
•
Braze all other joints with A.W.S. Bag-28 filler
metal.

prevent the formation of oxides which can contaminate
the oil and refrigerant systems.
N o t e : Use silver soldering with 96% Sn-4% Ag (for
example, J.W. Harris Co. Stay Brite®) to replace
brazing when the heat from brazing would be
detrimental to the immediate or nearby parts.
Examples:
1. Joints next to threaded joints in which the copper
or brass threads become too soft and/or Loctite®
loses its sealing capability due to excess heat.
2. Joints next to valves in which the valves cannot be
taken apart or are not recommended for brazing.
