Unit Nameplates

Unit Inspection

The CVGF unit nameplate
(Figure 2 shows the nameplate
location) is applied to the
exterior surface of the control
panel. The starter nameplate is
located inside the starter panel.

When the unit is delivered, verify
that it is the correct unit and that
it is properly equipped.

The unit nameplate provides the
following information:
• Unit model
• Unit serial number
• Unit device number - identifies
unit electrical requirements
- Lists correct operating
charges of HFC-134a and
lubrication oil
- Lists unit test pressures and
maximum working pressures
The starter nameplate provides
the following information:
• Panel model number
• Rated load amps
• Voltage
• Electrical characteristics starter type, wiring
• Options included

6

Inspect all exterior components
for visible damage. Report any
apparent damage or material
shortage to the carrier and make
a “unit damage” notation on the
carrier’s delivery receipt. Specify
the extent and type of damage
found and notify the appropriate
Trane Sales Office.
Do not proceed with installation
of a damaged unit without sales
office approval.

Inspection Checklist
To protect against loss due to
damage incurred in transit,
complete the pre-commissioning
checklist, which can be obtained
from your Trane representative.
• Inspect the individual pieces of
the shipment before accepting
the unit. Check for obvious
damage to the unit or packing
material.

• Inspect the unit for concealed
damage as soon as possible
after delivery and before it is
stored. Concealed damage
must be reported within 10
days after receipt.
• If concealed damage is
discovered, stop unpacking the
shipment. Do not remove
damaged material from the
receiving location. Take photos
of the damage, if possible. The
owner must provide reasonable
evidence that the damage did
not occur after delivery.
• Notify the Trane sales
representative and arrange for
repair. Do not repair the unit,
however, until damage is
inspected by the transportation
representative.

Information

Loose Parts Inventory

Unit Description

The loose parts items ship in the
motor junction box for units
without a unit-mounted starter,
or in the starter panel for units
equipped with a unit-mounted
starter. This includes the
isolation pads, extra oil filter,
and any optional factory-shipped
items.

The CVGF units are singlecompressor, gear-type, watercooled liquid chillers designed
for installation indoors. Each unit
is a completely assembled,
hermetic package that is factorypiped, wired, leak-tested,
dehydrated, oil-charged, and
tested for proper control
operation before shipment.
Note: high-voltage starters are
not unit-mounted before
shipment.

CVGF-SVN02B-E4

Figure 2 and Figure 3 show a
typical CVGF unit and its
components. Water inlet and
outlet openings are covered
before shipment. The oil tank is
factory-charged with 15 gallons
(56.8L) of Trane Oil 37 and a
holding charge of 5 psig (34 kPa)
of dry nitrogen at 70°F (21°C).
(See the Operation Maintenance
Manual for equivalent oil
specification.)

General
Information

Refer to the Mechanical and
Electrical sections of this manual
for detailed instructions.
• Locate and maintain the loose
parts such as, isolators, bulb
wells, temperature sensors,
flow sensors or other factoryordered field-installed options,
as required. Loose parts are
located in the starter panel if
equipped with a unit-mounted
starter. If not equipped with a
unit-mounted starter, loose
parts are shipped in the motor
junction box.
• Install the unit on a foundation
with flat support surfaces, level
within 1/4" (6 mm) and of
sufficient strength and mass to
support the chiller operating
weight. Place the manufacturersupplied isolation-pad
assemblies under the unit.
• Install the unit per the
instructions outlined in the
Mechanical Installation section.
• Complete all water piping and
electrical connections.

Note: Field piping must be
arranged and supported to
avoid stress on the equipment.
It is strongly recommended
that the piping contractor
provide at least 3 feet (914 mm)
of clearance between the preinstallation piping and the
planned location of the unit.
This will allow for the proper fit
upon arrival of the unit at the
installation site. All necessary
piping adjustments can be
made at that time.
• Where specified, supply and
install valves in the water
piping, upstream and
downstream of the evaporator
and condenser water boxes, in
order to isolate the shells for
maintenance and to balance
and trim the system.
• Supply and install flow
switches or equivalent devices
in both the chilled-water piping
and the condenser-water
piping. Interlock each switch
with the proper pump starter, to
ensure that the unit can only
operate when water flow is

Storage

Location Requirements

If the chiller is to be stored for at
least one month prior to
installation, observe the
following precautions:
• Do not remove the protective
coverings from the electrical
panel.
• Store the chiller in a dry,
vibration-free, secure area.
• At least every three months,
attach a gauge to the service
valve and manually check the
pressure of dry nitrogen in the
refrigerant circuit. If the
pressure is below 5 psig (34
kPa) at 70°F (20°C), call a
qualified service organization
and the appropriate Trane sales
office.

Noise Considerations
• Locate the unit away from
sound-sensitive areas.
• Install the isolation pads or
isolation springs under the
unit.
• Use rubber boot-type isolators
for all water piping at the unit.
• Use flexible electrical conduit
for final connection to the UPC.

32

Note: Consult an acoustical
engineer for critical applications.

Foundation
Provide rigid, non-warping
mounting pads or a concrete
foundation of sufficient strength
and mass to support the chiller
operating weight (including
completed piping and full
operating charges of refrigerant,
oil and water).

After the chiller is in place, level
the chiller within 1/4" (6 mm)
over its length and width.
Trane is not responsible for
equipment problems resulting
from an improperly designed or
constructed foundation.

Vibration Eliminators
• Use rubber boot-type isolators
for all water piping at the unit.
• Use flexible electrical conduit
for final connection to the UPC.
• Isolate all pipe hangers and be
sure they are not supported by
main structural beams that
could introduce vibration into
occupied spaces.
• Make sure that the piping does
not put additional stress on the
unit.
Note: Do not use metal braidedtype eliminators on the water
piping. Metal braided
eliminators are not effective at
the frequencies at which the unit
will operate.

Installation:
Mechanical

Clearances
Provide enough space around
the unit to allow the installation
and maintenance personnel
unrestricted access to all service
points. Refer to submittal
drawings for the unit
dimensions.
Allow adequate clearance for
condenser and compressor
servicing. A minimum of 36"
(914 mm) is recommended for
compressor service and to
provide sufficient clearance for
the opening of control panel
doors. Refer to Figures 4 and 5,
Tables 7 and 8 for minimum
clearances required for
condenser tube service. In all
cases, local codes will take
precedence over these
recommendations.

CVGF-SVN02B-E4

Notes: Required vertical
clearance above the unit is 36"
(914 mm). There should be no
piping or conduit located over
the compressor motor.
If the room configuration
requires a variance to the
clearance dimensions, contact
your Trane sales office
representative.

Water Pipe Connections
Table 9 applies to all CVGF
chiller tonnage sizes 500, 700
and 1000.
Refer to Table 9 for water pipe
connection sizing information
and evaporator and condenser
water pass information. All
measurement are in either US
or metric equivalents.

Ventilation
The unit produces heat even
though the compressor is
cooled by the refrigerant. Make
provisions to remove heat
generated by unit operation
from the equipment room.
Ventilation must be adequate to
maintain an ambient
temperature lower than 122°F
(50°C).
Vent the unit pressure relief
valves in accordance with all
local and national codes.
Make provisions in the
equipment room to keep the
chiller from being exposed to
freezing temperatures of 32°F
(0°C).

Water Drainage
Locate the unit near a largecapacity drain for water vessel
drain-down during shutdown or
repair. Condensers and
evaporators are provided with
drain connections. All local and
national codes apply.

Moving and Rigging
The Model CVGF chiller should
be moved by lifting at
designated lift points only. Refer
to the rigging diagram that ships
with each unit for specific per
unit weight data.

 WARNING
Heavy Objects!
Do not use cables (chains or
slings) except as shown. 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.
Other lifting arrangements may
cause equipment or propertyonly damage. Failure to properly
lift unit may result in death or
serious injury. See details
below:
• Follow the procedures and
diagrams in this manual and in
the submittal.
• Always use lifting equipment
with a capacity exceeding the
unit lifting weight by an
adequate safety factor. (+10%).

CVGF-SVN02B-E4

Installation:
Mechanical

Chiller Isolation
To minimize sound and vibration
transmission through the
building structure, and to assure
proper weight distribution over
the mounting surface, install
isolation pads or spring isolators
under the chiller feet.
Note: Isolation pads are
provided with each chiller unless
spring isolators are specified on
the sales order.
Specific isolator loading data is
provided in the until submittal
package. Also refer to Table 10. If
necessary, contact your local
Trane sales office for further
information.

Isolation Pads
When the unit is ready for final
placement, position isolation
pads end-to-end under the full
length of the chiller leg. The
pads measure 6" x 18" (152 x 457
mm). See Figure 6. No gaps
should be present between
pads.
Remember that the chiller must
be level within 1/4" (6 mm) over
its length and width after it is
lowered onto the isolation pads.
In addition, all piping connected
to the chiller must be properly
isolated and supported so that it
does not place any stress on the
unit.

CVGF-SVN02B-E4

Figure 6. Isolation pad

5/16-3/8"
(8-10 mm)

Spring Isolators
Spring isolators should be
considered whenever chiller
installation is planned for an
upper-story location. Spring
isolator selection and placement
information is presented in
Figure 7 and Figure 8.
Note: Three types of spring
isolators, shown in Tables 11-13
are used. Each type has its own
maximum loading
characteristics.
Spring isolators are typically
shipped 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. Position the spring isolators
under the chiller as shown in
Figure 7 and Figure 9. Make
sure that each isolator is
centered in relation to the
tube sheet.
2. Set isolators on the sub-base;
shim or grout them as
necessary to provide a flat,
level surface as the same
elevation for all mountings. Be
sure to support the full
underside of the isolator base
plate; no 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 cap
screws through the chiller
base and into the holes
tapped in the upper housing
of each isolator. Do not allow
the screws to protrude below
the underside of the isolator
upper housing. 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 the "Rigging" section
for lifting instructions.
The weight of the chiller will
force the upper housing of
each isolator down, perhaps
causing it to rest on the
isolator's lower housing.
Figure 9 illustrates spring
isolator construction.

37

Installation:
Mechanical

6. Check the clearance on each
isolator. If this dimension is
less than 1/4" (6 mm) on any
isolator, use a wrench to turn
the adjusting bolt one
complete revolution upward.
Repeat this operation until a
1/4" (6 mm) clearance is
obtained at all isolators.
7. After 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. Be
sure to work from one isolator
to the next.
Remember that the chiller
must be level to within 1/4" (6
mm) over its length and width
and that clearance of each
isolator must be 1/4" (6 mm).

Note: The spring isolator must be
centered in relation to the tube sheet. Do
not align the isolator with the flat part of
the chiller foot, because the tube sheet is
often off-center.

Note: Place isolator near outside edge of
tube sheet as shown.

either system water flow drops
below the required minimum
that is shown on the pressure
drop curves. Follow the
manufacturer’s
recommendations for selection
and installation procedures.
General guidelines for flow
switch installation are outlined
below.
• Mount the switch upright, with
a minimum of 5 pipe diameters
of straight, horizontal run on
each side.
• Do not install close to elbows,
orifices, or valves.

CVGF-SVN02B-E4

Note: The arrow on the switch
must point in the direction of the
water flow.
• To prevent switch fluttering,
remove all air from the water
system
Note: The CH530 provides a sixsecond time delay on the flow
switch input before shutting
down the unit on a loss-of-flow
diagnostic. If machine
shutdowns persist, contact your
local Trane representative.
• Adjust the switch to open when
water flow falls below nominal.

Refrigerant Pressure-Relief
Valve Venting

 WARNING
Possible refrigerant
asphyxiation!
Relief valve venting must be
vented outdoors. Refrigerant is
heavier than air and will
displace available oxygen to
breathe, causing asphyxiation or
other health risks. Each chiller
or Multiple chillers must have
their own separate relief valves
and vent piping. Consult local
regulations for any special reliefline requirements. Failure to
vent relief valves outdoors could
result in death and serious
injury.
Note: Vent pipe size must
conform to the ANSI/ASHRAE
Standard 15 for vent pipe sizing.
All country, federal, state, and
local codes take precedence over
any suggestions stated in this
manual.

54

All relief valve venting is the
responsibility of the installing
contractor.
All CVGF units use evaporator
and condenser pressure-relief
valves that must be vented to
the outside of the building.
Relief valve connection sizes and
locations are shown in the unit
submittals. Refer to local codes
for relief valve vent line sizing
information.

CAUTION
Do not exceed vent piping code
specifications. Failure to heed
specifications could result in
capacity reduction, unit damage,
and relief valve damage.

Thermal Insulation
All CVGF units are available with
optional factory installed
thermal insulation. If the unit is
not factory insulated, install
insulation over the areas with
designated dotted lines in Figure
13. Refer to Table 14 for types
and quantities of insulation
required. All CVGF units come
from the factory with oil sump
insulation.
Notes: Refrigerant charging
valves, water temperature
sensors, and drain and vent
connections, when insulated,
must remain accessible for
service.

After the relief valve has opened,
it will reclose when pressure is
reduced to a safe level.

Use only water-base latex paint
on factory applied insulation.
Failure to do so may result in
insulation shrinkage.

Note: Relief valves tend to leak if
they have opened and must be
replaced.

Note: Units in environments
with higher humidity may
require additional insulation.

phased; each power supply
conduit run to the starter must
carry the correct number of
conductors to ensure equal
phase representation. See
Figure 14.

6. As you install the power
supply conduit, make sure
that this position does not
interfere with the
serviceability of any of the
unit components, nor with
structural members and
equipment.
Also, assure that the conduit is
long enough to simplify any
servicing that may be necessary
in the future (for example,
starter removal).
Note: Use flexible conduit to
enhance serviceability and
minimize vibration transmission.

Starter to Motor (RemoteMounted Starters Only)
Ground Wire Terminal Lugs
Ground wire lugs are provided in
the motor terminal box and in
the starter panel.
Terminal Clamps
Terminal clamps are supplied
with the motor terminals to
accommodate either bus bars or
standard motor terminal wire
lugs. Terminal clamps provide
additional surface area to
minimize the possibility of
improper electrical connections.
Wire Terminal Lugs
Wire terminal lugs must be fieldsupplied.
1. Use field-provided crimp-type
wire terminal lugs properly
sized for the application.
Note: Wire size ranges for the
starter line and load-side lugs
are listed on the starter
submittal drawings supplied
by the starter manufacturer or
Trane. Carefully review the
submitted wire lug sizes for
compatibility with the
conductor sizes specified by
the electrical engineer or
contractor.

CVGF-SVN02B-E4

2. A terminal clamp with a 3/8"
bolt is provided on each
motor terminal stud; use the
factor-supplied Belleville
washers on the wire lug
connections.
Figure 18 illustrates the
juncture between a motor
terminal stud and terminal
clamp.
3. Tighten each bolt to 24 footpounds.
4. Install but do not connect the
power leads between the
starter and compressor motor.
(These connections will be
completed under supervision
of a qualified Trane service
engineer after the prestart
inspection).

CAUTION
Correct motor wire
terminations!
Ensure the power supply wiring
and output motor wiring are
connected to the proper
terminals. Failure to do so will
cause catastrophic failure of the
starter and, or the motor.
Bus Bars
Install bus bars between the
motor terminals when a lowvoltage “across-the-line,”
“primary reactor/resistor,” “auto
transformer,” customer-supplied
solid-state starter, or customersupplied AFD are field applied.

Be sure to bus motor terminal T1
to T6, T2 to T4, and T3 to T5.
Note: Bus bars are not needed in
high-voltage applications since
only 3 terminals are used in the
motor and starter.

Starter to UCP (RemoteMounted Starters Only)
Electrical connections required
between the remote-mounted
starter and the unit control panel
are shown in an example of a
point-to-point starter-to-UCP
connection diagram as shown at
the end of the manual.
Note: Install control voltage
conduit into control voltage
section of chiller control panel
and starter panel. Do not route
with low voltage (30 volts)
conduit wires.
When sizing and installing the
electrical conductors for these
circuits, follow the guidelines
listed.
Unless otherwise specified use
14 ga. wire for 120 V control
circuits.

61

Installation:
Electrical

CAUTION
Damage to Starter
components!
To avoid damage remove debris
inside the starter panel. Failure
to do so may cause an electrical
short that seriously damages
the starter components.
1. If the starter enclosure must
be cut to provide electrical
access, exercise care to
prevent debris from falling
inside the enclosure.
2. Use only shielded twisted pair
for the interprocessor
communication (IPC) circuit
between the starter and the
UCP on remote mounted
starters. Recommended wire
is Beldon Type 8760, 18 AWG
for runs up to 1000 feet.
Note: The polarity of the IPC
wire pair is critical for proper
operation.

62

3. Separate low-voltage (less
than 30V) wiring from the
115V wiring by running each
in its own conduit.
4. As you route the IPC circuit
out of the starter enclosure,
make sure that it is at least 6"
from all wires carrying a
higher voltage.
5. For UCP IPC shielded twisted
pair wiring, the shield should
be grounded on one end only
at UCP at 1X1-G. The other
end should be unterminated
and taped back on the cable
sheath to prevent any contact
between shield and ground.
6. Oil Pump Interlock - All
starters must provide an
interlock (N.O.) contact with
the chiller oil pump connected
to the UCP at Terminals 1A-J27 and 1A9-J2-9.

The purpose of this interlock is
to power the oil pump on the
chiller in the event that a starter
failure, such as welded contacts,
keeps the chiller motor running
after the controller interrupts the
run signal.

CAUTION
Electrical Noise!
Maintain at least 6 inches
between low-voltage (<30V) and
high voltage circuits. Failure to
do so could result in electrical
noise that may distort the
signals carried by the lowvoltage wiring, including the
IPC.

Unit Start-Up

Forms Information

Optional Control and Output
Circuits

All phases of initial unit start-up
must be conducted under the
supervision of a qualified local
service engineer. This includes
pressure testing, evacuation,
electrical checks, refrigerant
charging, actual start-up and
operator instruction.

Samples of start-up and
operating forms along with
other helpful forms are found in
the Operation Maintenance
manual which can be obtained
from the nearest Trane office.

Install various optional wiring as
required by the owner’s
specifications.

Optional Tracer
Communication Interface
This control options allows the
unit control panel to exchange
information such as chiller
status and operating set points
with a Tracer system.
Figure 19 illustrates how such a
communication control network
might appear.
Note: The circuit must be run in
separate conduit to prevent
electrical noise interference.
Additional information about the
Tracer Communication options
is published in the installation
manual and operator’s guide
that ships with the Tracer.

64

Advance notification is required
to assure that initial start-up is
scheduled as close to the
requested date as possible.

Starter Module
Configuration
The starter LLID configuration
settings will be checked (and
configured for Remote Starters)
during start-up commissioning.
To configurate starter module,
and perform other starter
checks, it is recommended that
the line voltage three phase
power be turned off and secured
(locked out), and then a separate
source control power (115 Vac)
be utilized to power up the
control circuit. To do this,
remove control coil circuit fuse,
typically 2F4, and then connect
separate source power cord to
starter terminal block 2X1-1 (H),
2X1-2 (N), and Ground. Use the
as-built starter schematic to
assure correct fuse and
terminals. Verify correct fuse is
removed, control circuit
connections are correct, then
apply the 115 Vac separate
source power to service the
controls.

It is recommended that the
serviceman contact the local
Trane office to obtain the most
recent printing date of the form.
The forms in the operation and
maintenance manual are only
current at the time of printing of
the manual.
After obtaining the most recent
form, complete all the
information and forward it to
your local Trane office.
