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.
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 AirAct (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 Indicates a situation that could result in
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/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 Safety Data Sheets
(SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals,
ALWAYS refer to the appropriate SDS and OSHA/GHS
(Global Harmonized System of Classification and
Labeling 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

General Information
About This Manual
This manual is provided to support the factory-assembled
CVRF complete control panel for former single door pneumatic
control panels. This work replaces the older pneumatic control
panel with the current Symbio™ Chiller Control system. The
factory-assembled portion is the control panel only. Some of
the control items will be field-installed.
The step-by-step instructions outlined in this manual describe
the procedures required to successfully install Symbio™
controls on PCVs, CVs, and CTVs with a single door
pneumatic-based control system.
Notice that the installation instructions in this manual are
divided into the following general topic areas:
1. Control panel installation includes removal of existing
control panel. It is followed by installation of new panel and
mounting brackets, and wiring in the new control panel.
2. Sensor installation includes the mounting of temperature
and pressure sensors and wiring instructions.
3. Starter Panel planning for wye-delta starter applications,
as well as additional information for converting non-wye-
delta starters.
4. Actuator mounting includes removal of the old pneumatic
actuator and installation instructions for the stepper IGV
actuator.
5. Accessories and options installation includes information
on how to install and wire any optional LLIDs or
components. LLIDs are individual control components that
communicate with the main processor.
Note: New Symbio™ and older Trane®wiring diagrams are
often referenced throughout this manual. Locate any
drawings reflecting changes, upgrades, or BAS tie-ins
that have been performed on the unit since original
installation. A complete set of Symbio™ wiring
diagrams are referenced in “Wiring Diagram Matrix,”
p. 41 in this manual. Also referenced in this manual are
wiring diagrams that are representative of the machine
you will be retrofitting. You may find it helpful to obtain
a copy of the machine or job specific drawings before
you attempt to perform the control system conversion.
Application Guidelines
This Symbio™ control package is specifically designed to
upgrade the controls of older Trane®(PCV, CV, and CTV)
water cooled chillers having pneumatic controls that are
housed in a single door, horizontal style enclosure.
Getting Started
To properly install a Symbio™ upgrade, the technician must
have a good knowledge of Symbio™ control systems. Training
in Symbio™ controls is highly recommended before beginning
this retrofit.

Installation
Control Panel Conversion
The control panel conversion will consist of removing, marking,
and retaining selected wires in the existing control panel. The
existing control panel will be removed. The new control panel
will be installed. The existing wires will be terminated on the
terminal block or LLIDs in the control panel along with any new
wires required.
Make a note of run hours and starts on the hour meter and start
counter. Symbio™ 800 will allow you to enter this information
into its program.
Remove the nameplate from the existing panel by cutting the
rivets holding it on. If the chiller original nameplate is a stick-on
label, it may be necessary to cut out the metal section. This
nameplate needs to be moved and attached to the new control
panel near the new control panel nameplate. The old
nameplate contains original unit information that will be useful
in service and parts issues in the future.
Before You Begin
1. Identify all field modifications made to the existing chiller
control scheme; then label all field-installed wiring entering
the control panel accordingly, if required. This may include
things like the power supply for the purge and any BAS
interface wiring.
2. Determine how each of the field-adapted control functions
just identified in Step 1 will be assumed by the new
Symbio™ chiller control panel.
3. Capture all existing chiller control settings before powering
down chiller controls.
4. Open all starter and control panel disconnect switches and
secure them in the open position.
5. Disconnect the leads at the control panel terminal block
from the oil heater (wire numbers 10 and LL2), oil pump
(wire numbers 12 and LL2) and purge (wire numbers 3, 4,
and LL2). Insure that these wires are properly identified
and marked before disconnecting them. To assist in the
identification of wires, refer to the job specific wiring
diagrams (see “Wiring Diagram Matrix,” p. 41 for a list of
“typical” original wiring diagrams). Note that these are only
a typical wiring diagram and is not meant to be an accurate
representation of the machine being retrofit.
Note: To eliminate migration of refrigerant into the oil sump,
temporarily connect a field supplied thermostat and an
auxiliary 115 volt power source to the oil heater.

WARNING
Hazardous Voltage w/Capacitors!
Failure to follow instructions below could result in
death or serious injury.
Disconnect all electric power, including remote
disconnects and wait for DC capacitors to discharge
before servicing. Refer to the manufacturer’s
recommendations for proper discharge time as DC bus
capacitors retain hazardous voltages after input power
has been disconnected. Follow proper lockout/ tagout
procedures to ensure the power cannot be
inadvertently energized. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged before touching any internal components.
WARNING
PPE for Arc/Flash Required!
Failure to wear appropriate PPE could result in death or
serious injury.
On this unit, if the handle shield is cracked the circuit
breaker could arc/flash when reset. To avoid being
injured, technicians MUST put on all necessary
Personal Protective Equipment (PPE), in accordance
with NFPA70E for arc/flash protection, PRIOR to
entering the starter panel cabinet.

Installation
12 CVRF-SVN001C-EN
6. Disconnect all field-installed wiring entering the control
panel (i.e., identified in Step 1) from the control panel
terminal strip. Also identify chilled and condenser water
flow circuits.
7. Remove from the control panel terminal block all wiring that
has been routed through conduit from the starter panel to
the control panel (wire numbers LL1, LL2, 2, and 7. This
should include wires from the variable ratio current
transformer (wire numbers 8A, 8B, 8C, 8D, and 9). Insure
that these wires are properly identified before
disconnecting them. Many of these wires will be re-
terminated to the terminal block in the new panel.

8. Remove the sensor bulbs of the following and place them
inside the control panel enclosure.
a. Motor temperature cutout switch (MTC),
b. High oil temperature switch (OTC), and
c. Low refrigerant temperature switch (LTC).
9. Valve off, disconnect, and remove any pneumatic lines at
the control panel.
10. Oil differential pressure switch (OPC):
The OPC will be replaced by individual oil pressure
transducers outside the new control panel. Before the
existing control panel can be removed, the OPC must be
removed and the new oil pressure transducers installed.
Care must be taken to prevent infiltration of air into the
machine during the installation.
Removal of Existing Panel
Remove the existing chiller control panel. The existing
brackets on the chiller will be reused to mount the new control
panel. New isolators are provided with the new panel so
discard the old isolators.
Installation of New Control Panel
Install the new control panel The two isometric views at the top
of the figure show the space required for the control panel
based on the mounting holes used. The bottom bracket has
two sets of holes so the control panel can be positioned to
avoid interference with the condenser shell.
Adapter brackets and hardware are provided. New holes may
need to be drilled in existing brackets. Mark and drill holes as
required.
It may be necessary to modify the supplied adapter brackets
for your specific application.

Wiring Installation
Unless otherwise indicated, all 115 volt control circuits use, as
a minimum, #16 AWG, 600 volt wire. Be sure to use existing
conduit wherever possible and separate all
115V wiring from any low voltage circuits.
Most wiring will use the existing wires removed and marked
from the original panel and moved to the terminal block in the
new panel. Some wires may need to be connected directly on
a LLID terminal. For all control panel wiring, refer to wiring
diagrams shipped with the kit and to the connection and
schematic diagrams listed in “Wiring Diagram Matrix,” p. 41 for
additional detail.
For 50 Hz applications, the control power transformer (1T1) is
supplied as a 60 Hz application. To convert from 60 Hz to 50Hz,
the following step must be performed: move wire 2H from H3
on 1T1 to H2.
If you have wired a temporary thermostat and 115 volt power
source to the oil heater leads, wait to connect these wires until
the Symbio™ retrofit is complete to avoid too much cooling of
the oil.
Motor Temperature Devices
The new Symbio™ panel comes with the motor winding
temperature input LLID (IA26). This is used for motors that
have RTD-type sensors embedded in the motor windings. If
the motor does not have RTD-type sensors, motor
temperature protection can be accomplished a temperature
sensor which installed in the bulb well of the motor, and
connect to the IPC bus.
Mount Display Arm and Display
1. Secure the arm to the control panel using the
5/16 - 18 x 1-inch hex bolts, 5/16 - inch lock washers, and
5/16 - 18 hex nuts provided. There are pre-drilled holes on
the left and right sides of the control panel; select the side
that’s most suitable for your specific application.
Note: There is a production display arm bracket
BRK04345 provided that where applicable can be
mounted to the existing control panel mounting
arms. When used, the holes on the unused side(s)
should be plugged.
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.

3. After the display is attached, recheck the arm tension. The
arm tension should be set so that the display does not
spring up or sag down out of the position it is moved to by
the operator.
Adjusting the Tracer®AdaptiView™
Display Arm
The Tracer®AdaptiView™ display arm may be too loose or too
tight and in need of adjustment. To adjust the tension on the
display arm:
1. There are three joints on the display arm that allow the
Tracer®AdaptiView™ display to be positioned at a variety
of heights and angles (refer to items labeled 1, 2, and 3 in
Figure 9, p. 16). At each joint in the display arm there is
either a hex bolt (1 and 2) or hex screw (3). Turn the hex
bolt or screw in the proper direction to increase or decrease
tension.
Note: Each hex bolt or screw is labeled with ‘loosen’/
‘tighten’, or '+'/'–' indicators.
2. Joint 3 has a 6 mm hex screw controlling the tension on a
gas spring, which allows the Tracer®AdaptiView™ display
to tilt up and down.
3. Joints 1 and 2 are covered by a plastic cap. Remove the
plastic cap to access the hex bolt. Adjust using a 13 mm
wrench as necessary.
4. To adjust the swivel of the Tracer®AdaptiView™ display
(the spin right and left similar to the steering wheel on a
car), you need to adjust the hex bolt located inside the
display arm back plate. This adjustment needs to be done
BEFORE attaching the display. Use a 9/16 inch or 14 mm
wrench.
5. Use a 13 mm wrench to adjust the bolt (item labeled 4 in
Figure 9, p. 16) that allows the entire display arm to swivel
to the left and right.
Oil Pressure Transducer Installation
The oil differential pressure switch (1S2) will be replaced with
two Symbio™ pressure transducers.
1. The copper lines leading to the existing DP switch will be
modified for reuse with the new sensors. The Symbio™
pressure sensors are 1/4 inch MPT. Fittings are supplied to
convert from the existing flair connection to 1/4 inch female
pipe thread. Use Loctite®277 on threads of conversion
piece to prevent leaks. Use Loctite®565 on pressure
transducer so connection can be broken without heat if
future replacement of pressure transducer is required.
Note which line is oil pump discharge pressure and which
is sump pressure. Quickly attach sensors to lines to avoid
large quantities of air entering machine.
The transducers can be mounted in any direction. Lines
should be routed and transducers mounted to minimize
any potential stacking of liquid on top of the transducers.
If desired, Symbio™ pressure transducers can be
mounted externally from the control cabinet (see
Figure 10, p. 17). This can be done to avoid spraying
control panel components with oil if the fittings should leak.
Use caution with copper lines to avoid crimping if moving
outside control cabinet.
CAUTION
Tension in Display Support Arm!
Failure to follow instructions below could result in
unexpected movement of the spring-loaded support
arm which could result in minor to moderate injury.
Ensure that the support arm is in the full upright
position when removing the Tracer®AdaptiView™
display from the support arm.

2. Remove oil differential pressure switch and wires from
enclosure. Symbio™ 800 does not require the switch
function so the switch and associated wiring can be
discarded.
3. Once the new panel is installed attach pressure
transducers to the cabinet using adhesive pads and wire
ties or similar method.
Sensor Installation and Wiring
Existing single door sensors cannot be used with a Symbio™
retrofit. It is recommended that existing bulb wells be used.
Installing new wells would necessitate opening the chiller to
atmosphere.
If installing new bulb wells (optional), use safe refrigerant
practices to evacuate the chiller.
Install and wire each of the temperature sensors listed below.
When the sensor is installed in a bulb well, be sure to:
• Add thermastic paste to each bulb well before inserting the
sensor.
• Ensure that the sensor “bottoms out” at the base of the bulb
well.
It is recommended that sensors “1” through “3” be mounted in
wells. The rest may be installed externally. Connect all
Symbio™ temperature sensors to the main IPC bus using the
provided pluggable cables.
The Symbio™ component identification is in parenthesis
following each sensor name:
1. Oil tank temperature sensor (4R5).
2. Evaporator leaving water temperature sensor (4R7).
3. Evaporator saturated refrigerant temperature sensor
(4R10).
4. Condenser entering and leaving water temperature
sensors (4R8 and 4R9).
5. Evaporator entering water temperature sensor (4R6).
6. Condenser saturated refrigerant temperature sensor
(4R11).
Locate sensor at the bottom of the condenser or on the
condenser liquid line upstream of any orifices or float
valves.
Note: If unit has an EarthWise™ purge, PRGD (CH530
controls), the sensor bound as Condenser
Saturated Refrigerant Temperature Sensor (used
as Purge Liquid Temperature) cannot be used and
will need to be unbound. Install the temperature
sensor sent with the Symbio™ components as
described above.
7. Condenser discharge refrigerant temperature sensor
4R16 (optional). This sensor is only shipped if Hot gas
bypass or Enhanced Protection packages were ordered
and are to be installed.
8. Bearing temperature sensors: inboard-4R1, outboard-4R2
(optional). These sensors are only shipped if Enhanced
Protection package was ordered and is to be installed.
Mounting Sensors Externally
1. Remove the paint and rust from the pipe or chiller surface;
then use a wire wheel to expose bare metal.
2. Epoxy the supplied plastic sleeve to the pipe surface. Use
Loctite®Epoxy Quick Set or equivalent, Figure 11, p. 18.
3. Install the sensor probe, with thermastic paste, into the
sleeve. Wire tie the sensor leads to the plastic sleeve tab.
4. Wrap the sensor with Armaflex®insulation, Figure 12,
p. 18.

2. Remove the existing pulse IGV actuator and existing
conduit and wire.
3. Install the new IGV actuator on the chiller.
a. Use the connecting hardware retained when the old
pulse actuator was removed.
b. Use the existing actuator mounting plate, piston yoke
and mounting hardware to install the new electric
actuator.
The motor can be rotated 180 degrees to accommodate
existing hardware. The actuator rod may be connected to the
mounting plate at the compressor housing or to the vane
linkage.
4. The IGV ships in a mid-position. The first time the IGV is
powered up, it will drive closed. This may mean travel as
much as 1 inch. Disconnect the IGV actuator from the IGV
linkage until fully retracted.
Note: For PCV-2C through PCV-3J units, the stroke of the
actuator is towards the compressor.
Running the IPC Bus
There are several ways to string the IPC communication bus
on the chiller. The Symbio™ retrofit kit includes a general wire
kit that has several different types of wires. An example of a
wiring layout can be seen in Figure 15, p. 19. Each application
will vary depending on the options. You may have extra cables,
or may be short needed cables. Extra cables can be ordered
through your local Trane Parts Center. Refer to PART-SVB16*-
EN for identification of individual cables.
