this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required.Yourpersonalsafetyandtheproperoperationof
this machine depend upon the strict observance of these
precautions.
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.Traneadvocatestheresponsiblehandlingof
all refrigerants-including industry replacements for CFCs
such as HCFCs and HFCs.
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. 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.
The three types of advisories are defined as follows:
WARNING Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTIONsIndicates 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.
NOTICE: Indicatesasituationthatcouldresultin
equipment or property-damage only
accidents.
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 electrical codes.
WARNING
Personal Protective Equipment (PPE)
Required!
Installing/servicing this unit could result in exposure to
electrical, mechanical and chemical hazards.
• 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 inaccordance
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.
Failure to follow instructions could result in death or
serious injury.

Pre-Installation
ASHRAE Standard 15 Compliance
Trane recommends that indoor CenTraVac unit
installations fully meet or exceed the guidelines of the
currentversionofASHRAEStandard 15,inadditiontoany
applicable national, state, or local requirements. This
typically includes:
• A refrigerant monitor or detector that is capable of
monitoring and alarming within the acceptable
exposure level of the refrigerant, and that can actuate
mechanical ventilation.
• Audibleandvisualalarms, activated by the refrigerant
monitor, inside the equipment room and outside of
every entrance.
• Theequipmentroomshouldbe properly vented to the
outdoors, using mechanical ventilation that can be
activated by the refrigerant monitor.
• The purge discharge and the rupture disk must be
properly piped to the outdoors.
• If required by local or other codes, a self-contained
breathing apparatus should be available in close
proximity to the equipment room.
RefertothelatestcopyofASHRAEStandard 15forspecific
guidelines. Trane assumes no responsibility for any
economic,health,orenvironmentalissuesthatmayresult
from an equipment room’s design or function.
Unit Shipment
Inspect unit while it is still on the truck for any shipping
damage. The chiller ships shrink-wrapped in a 0.010-in.
(0.254 mm) recyclable film protective covering. Do not
remove shrink-wrapfor inspection!Inspectfordamageto
the shrink-wrap and determine if physical damage has
occurred.
Each chiller ships from the factory as a hermetically
assembled package; it is factory-assembled, -wired, and
-tested. All openings except for the waterbox vent and
drain holes are covered or plugged to prevent
contamination during shipment and handling. Figure 2,
p. 11 shows an illustration of a typical unit and its
components. As soon as the unit arrives at the job site,
inspect it thoroughly for damage and material shortages.
In addition:
1. Verify the hermeticintegrityoftheunitbychecking the
chiller pressure for an indication of holding charge
pressure.
2. To prevent damaging moisture from entering the unit
and causing corrosion, each chiller is pressurized with
3 to 5 psig (20.7 to 34.5 kPaG) of dry nitrogen before
shipment.
Note: The holding charge should register approximately
5 psig(34.5 kPaG)at72°F(22.2°C).Placeagaugeon

General Weights
The unit weight information provided in Table 2 should
be used for general information purposes only. Trane
does not recommend using this weight information for
considerations relative to chiller handling. The large
number of variances between chiller selections drives
variances in chiller weights that are not recognized in
this table. For specific weights for your chiller, refer to
your submittal package.
The values in Table 2 representing chiller weights include
the following:
•TECU 0.028-in. tube wall.

Installation: Mechanical
Operating Environment
Important:
•The standard chiller is designed for indoor use only
and as such has NEMA Type 1 enclosures.
•For chillers in unheated equipment rooms, contact
yourlocal Traneservice agency formethods toensure
that the oil temperature is maintained suitable for
proper operation of the chiller.
Toensure that electrical components operateproperly,do
not locate the chiller in an area exposed to dust, dirt,
corrosive fumes, or excessive heat and humidity. The
maximum ambient temperature for chiller operation is
104°F (40°C).
Foundation Requirements
Chiller mounting surface must be:
•rigid non-warping mounting pads or a concrete
foundation.
•abletosupportthechilleratitsfulloperatingweight
(including completed piping, and full operating
charges of refrigerant, oil and water.)
For proper unit operation, the chiller must be level within
1/16 in. (1.6 mm) over its length and width when set into
place on the mounting surface. Table 2, p. 13 shows
approximate weights for various chiller sizes and options.
Note: For specific weight information, refer to the unit
submittal package.
Important: Trane will not assume responsibility for
equipment problems resulting from an
improperly designed or constructed
foundation.
Rigging
Lifting is the recommended method for moving chillers.
Suggested lifting arrangements for standard units are
described in “Standard Chiller Lift,” p. 16.
Note: The lifting beam used for Simplex units must be at
least 16 feet (4.8768 meters) long.
Standard Chiller Lift
1. Insert clevis connections at the points indicated in
Figure 4, p. 17. A 2 in. (50.8 mm) diameter lifting hole
is provided at each of these points.
2. Attach the lifting chains or cables.
3. Oncetheliftingcablesareinplace,attachasafetychain
or cable between the first-stage casing of the
compressor and the lifting beam.
Important: There should not be tension on this safety
cable; the cable is used only to prevent the
unit from rolling during the lift.
4. Position isolator pads or spring isolators beneath the
chiller feet (refer to “Unit Isolation,” p. 18 for
instructions).
Note: Follow instructions provided by the spring
isolator manufacturer, being careful to not
damage isolator adjustment bolt.
5. Once the isolators are in place, lower the chiller—
working from end to end—in small increments to
maintain stability.
6. When lift is complete, detach the clevis connections
and safety chain.
NOTICE:
Equipment Failure!
Unit operating at ambient temperatures exceeding
104°F (40°C) could fatigue the unit’s rupture disk,
causing it to break at a reduced refrigerant pressure
(<15 psig [<103.4 kPaG]). Starter component damage
could also occur due to the panel’s inability to dissipate
heat adequately. If any of these adverse operating
conditions are present, take necessary action to
improve the equipment room environment.
WARNING
Heavy Objects!
Failure to properly lift unit could result in death or
serious injury, or equipment or property-only damage.
Do not use cables (chains or slings) except as shown in
Figure 4, p. 17. Each of the cables (chains or slings)
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.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in death or
serious injury, or equipment or property-only damage.
Test lift unit approximately 24 inches (61 cm) to verify
proper center of gravity lift point. To avoid dropping of
unit, reposition lifting point if unit is not level.
NOTICE:
Wiring Damage!
Damage to unit wiring could result in equipment
failure. Care must be taken during rigging, assembly
and disassembly to avoid damaging unit wiring.

Special Lift Requirements
If the chiller cannot be moved using a standard chiller lift,
consider the following:
• When job site conditions require rigging of the chiller
at an angle greater than 45° from horizontal (end-to-
end), the unit may require removal of the compressor.
Contact Trane or an agent of Trane specifically
authorized to perform start-up and warranty of Trane®
products regarding the disassembly and reassembly
work.Formoreinformation,referto“FactoryWarranty
Information,” p. 3.
Note: Disassembly and reassembly work includes
dowel-pinningthecompressorandremovingit
from the unit. Contact Trane or an agent of
Trane specifically authorized to perform start-
upandwarrantyofTrane®productsforspecific
rigging instructions. Do NOT attempt to rotate
the chiller onto its side.
• When lifting the chiller is either impractical or
undesirable,attachcablesorchainstothe jackingslots
shown in Figure 4, p. 17; then push or pull the unit
across a smooth surface. Should the chiller be on a
shipping skid, it is not necessary to remove the skid
from the chiller before moving it into place.
• If removal of the compressor or economizer assembly
is necessary to move the chiller to the operating
location, contact Trane. For more information, refer to
“Factory Warranty Information,” p. 3.
Unit Isolation
Tominimizesoundandvibrationtransmissionthroughthe
building structure, and to ensure proper weight
distribution over the mounting surface, always install
isolation pads or spring isolators under the chiller feet.
Note: Isolationpads(seeFigure 5)areprovidedwitheach
chiller unless spring isolators are specified on the
sales order.
Specific isolator loading data is provided in the unit
submittal package. If necessary, contact your local Trane
sales office for further information.
Important: When determining placement of isolation
padsor springisolators,rememberthat the
control panel side of the unit is always
designated as the unit front.
Isolation Pads
When the unit is ready for final placement, position
isolation pads (18-in. sides) end for end under the full
length of the chiller leg. The pads measure 6 in. × 18 in.
(152.4 mm x 457.2 mm) and on some units there may be
small gaps between pads. Pads are provided to cover
entire foot.
Remember that the chiller must be level within 1/16 in.
(1.6 mm) over its length and width after it is lowered onto
the isolation pads. In addition, all pipingconnected to the
chiller must be properly isolated and supported so that it
does not place any stress on the unit.
Spring Isolators
Spring isolators should be considered whenever chiller
installation is planned for an upper story location. Base
isolator placement is shown in Figure 6.
NOTICE:
Oil Loss!
Failure to prevent oil migration out of the oil tank could
result in equipment failure or property-only damage. To
prevent oil migration out of the oil tank during lifting
procedures, remove the oil from the oil tank if the unit
will be lifted at any angle greater than 15° from
horizontal end-to-end. If oil is allowed to run out of the
oil tank into other areas of the chiller, it will be
extremely difficult to return the oil to the oil tank even
during operation.
NOTICE:
Equipment Damage!
Moving the chiller using a fork lift could result in
equipment or property-only damage. Do not use a fork
lift to move the chiller!
NOTICE:
Compressor Alignment!
Failure to preserve compressor alignment could result
in equipment or property-only damage. Lifting the
compressor/motor assembly from the shells without
factory-installed doweling in the compressor casting
flanges could result in misalignment of the compressor
castings. Figure 5. Isolation pad and dimensions

Spring isolators typically ship assembled and ready for
installation. To install and adjust the isolators properly,
follow the instructions given.
Note: Do not adjust the isolators until the chiller is piped
and charged with refrigerant and water.
1. Positionthespringisolatorsunderthechillerasshown
in Figure 6. Ensure that each isolator is centered in
relation to the tube sheet.
Note: Spring isolators shipped with the chiller may
not be identical. Compare the data provided in
theunitsubmittalpackage to determine proper
isolator placement.
2. Settheisolatorsonthesub-base;shimasnecessaryto
provide a flat, level surface at the same elevation for
the end supports.
Important: Support the full underside of the isolator
base plate; do NOT straddle gaps or small
shims.
3. If required, bolt the isolators to the floor through the
slots provided, or cement the pads.
Note: Fastening the isolators to the floor is not
necessary unless specified.
4. If the chiller must be fastened to the isolators, insert
capscrews through the chiller base and into holes
drilled and tapped in the upper housing of each
isolator.
Important: DoNOTallowthe screwstoprotrudebelow
theundersideoftheisolatorupperhousing,
or interfere with the adjusting bolts. An
alternative method of fastening the chiller
to the isolators is to cement the neoprene
pads.
5. Set the chiller on the isolators; refer to “Standard
Chiller Lift,” p. 16. The weight of the chiller will force
down the upper housing of each isolator, and could
causeittorestontheisolator’s lower housing(referto
Figure 7).
.
6. Check the clearance on each isolator. If this dimension
is less than 1/4 in. (6.35 mm) on any isolator, use a
wrench to turn the adjusting bolt one complete
revolution upward.
Note: When the load is applied to the isolators (Step 5),
the top plate of each isolator moves down to
compress the springs until either the springs
support the load or the top plate rests on the
bottom housing of the isolator. If the springs are
supporting the load, screwing down on the
adjusting bolt (Step 7) will raise the chiller.
7. Turn the adjusting bolt on each of the remaining
isolators to obtain the required minimum clearance of
1/4in.(6.35mm).
8. Once the minimum required clearance is obtained on
each of the isolators, level the chiller by turning the
adjusting bolt on each of the isolators on the low side
of the unit. Work from one isolator to the next.
Important: The chiller must be level to within 1/16 in.
(1.6 mm) over its length and width, and the
clearanceofeach isolator mustbeat least 1/
4in.(6.35mm).

Leveling the Unit
The chiller must be set level within 1/16 in. (1.6 mm).
1. Measureand make a punch mark anequal distance up
from the bottom of each foot of the chiller.
2. Suspend a clear plastic tube along the length of the
chiller as shown in the following figure.
3. Fill the tube with water until the level aligns with the
punch mark at one end of the chiller.
4. Checkthe waterlevel at theopposite mark.Ifthe water
level does not align with the punch mark, use full
length shims to raise one end of the chiller until the
water level at each end of the tube aligns with the
punch marks at both ends of the chiller.
5. Once the unit is level across its length, repeat Step 1
through Step 3 to level the unit across its width.
Note: Use of a laser level is an acceptable alternative
method to level the unit.
Important: Immediately report any unit damage
incurred during handling or installation at
the job site to the Trane sales office.
