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.
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.

Unit Description
Before shipment, each unit is leak tested, dehydrated,
charged with refrigerant and compressor oil, and run tested
for proper control operation.
Direct-drive, vertical discharge condenser fans are
provided with built-in thermal overload protection. The
stages of capacity control for these units are achieved by
starting the Economizer Control Actuator (ECA).
RT-SVX083B-EN
General Information
Economizer Control Actuator
Electromechanical Control
The ECA monitors the mixed air temperature, return air
temperature, minimum position setpoint (local or remote),
power exhaust setpoint, CO2 setpoint, CO2, and ambient
dry bulb/ enthalpy sensor or comparative humidity (return
air humidity against ambient humidity) sensors, if selected,
to control dampers to an accuracy of ±5 percent of stroke.
The actuator is spring returned to the closed position any
time that power is lost to the unit. It is capable of delivering
up to 25 in﹒lb of torque and is powered by 24 Vac.
JADE Economizer Control - Low Leak
Economizer (LLE) Only
The JADE controller is a standalone economizer controller
that provides outdoor air dry-bulb economizer control
standard. With optional Sylk Bus sensors, the controller
can provide comparative or reference enthalpy control.
Dampers are controlled to an accuracy of ±3.2 percent of
stroke. The actuator is spring returned to the closed
position any time that power is lost to the actuator. It is
capable of delivering up to 44 in﹒lb of torque and is powered
by 24 Vac.
System Input Devices and Functions
The unit must have a thermostat input in order to operate.
The descriptions of the following basic input devices used
within the unit are to acquaint the operator with their
function as they interface with the various features. Refer to
the unit’s electrical schematic for the specific device
connections. The following controls are available from the
factory for field installation.
Drain Pan Condensate Overflow Switch
(Optional)
This input incorporates the Condensate Overflow Switch
(COF) mounted on the drain pan. When the condensate
level reaches the trip point, the COF relay energizes and
opens the 24 Vac control circuit, disabling the unit. A delay
timer prevents the unit from starting for 3 minutes.
Phase Monitor
The Phase Monitor is a three-phase line monitor module
that protects against phase loss, phase reversal and phase
unbalance. It is intended to protect compressors from
reverse rotation. It has an operating input voltage range of
180 to 600 Vac, and LED indicators for ON and FAULT.
There are no field adjustments and the module will
automatically reset from a fault condition.
Discharge Line Thermostat Control
When LSD is present in the unit, the high pressure controls
and the discharge line thermostat signals are wired in
series and connected to the safety input of the LSD. The
compressor contactor coil is connected to the CC terminal
RT-SVX083B-EN
of the LSD. If the high pressure control switch or the
discharge line thermostat is open, the 24 Vac signal to the
SI input of the LSD is interrupted and the compressor
contactor coil supply is disabled by the LSD. It has an
automatic lockout.
Power Exhaust Control (Optional)
The power exhaust fan is started whenever the position of
the economizer dampers meets or exceed the power
exhaust setpoint when the indoor fan is on.
The setpoint panel is located in the return air section and is
factory set at 25% (50% for LLE).
To configure the LLE controller, set EXH1 SET (or EXH1 L
and EXH1 H with two-speed fan) in the SETPOINTS menu.
2-speed fan mode requires AUX2 I set as W.
Evaporator Frost Control (Optional)
This input incorporates the Frostat™ control (FOS)
mounted in the indoor coil and can be activated by closing
a field supplied contact installed in parallel with the FOS.
If this circuit is open before the compressor is started, the
compressor will not be allowed to operate. Anytime this
circuit is opened for 5 continuous seconds during
compressor operation, the compressor for that circuit is
immediately turned Off. The compressor will not be
allowed to restart for a minimum of 3 minutes should the
FOS close.
Sensors
High Temperature Sensor (BAYFRST003*)
This sensor connects to the Emergency Stop Input on the
LTB and provides high limit shutdown of the unit. The
sensor is used to detect high temperatures due to fire in the
air conditioning or ventilation ducts. The sensor is designed
to mount directly to the sheet metal duct. Each kit contains
two sensors. The return air duct sensor (X1310004001) is
set to open at 135°F.
The supply air duct sensor (X1310004002) is set to open at
240°F. The control can be reset after the temperature has
been lowered approximately 25°F below the cutout
setpoint.
Thermostat (TCONT802AS32DA)
This thermostat is a multi-stage 3 heat/2 cool,
autochangeover digital display thermostat. It is a
programmable thermostat, and a 7-day programmable stat
with night setback shall be available. In addition, it is wall
mounted.
Thermostat (TCONT402AN32DA)
This thermostat is a multi-stage 3 heat/2 cool, auto
changeover digital display thermostat. It is a nonprogrammable, wall-mounted thermostat, and it can be
used for economizer operation.

General Information
CO2 Sensor
This optional sensor can be added for Demand Control
Ventilation (DCV) functionality. On units with a low leak
economizer, configure the JADE controller by setting the
following parameters:
sensor must utilize a normally open contact for proper
operation.
DCV SET = desired CO2 ppm to start DCV
If an occupancy sensor is not used, another option to
controlling occupied and unoccupied status is to use the G
input (fan is running). Connect the G input to the OCC
SENSOR wire (at customer connections). The controller
will then operate in the occupied mode every time the
indoor fan is running.
VENTMAX = desired maximum position w/DCV and
occupied status (2-speed applications require LO and HI
settings)
Initiation of Operating Modes - JADE
Controller
VENTMIN = desired minimum position w/DCV and
occupied status (2-speed applications require LO and HI
settings)
The JADE controller is able to initiate the following modes:
Compressor, Economizer, Fans, Heating System, and
Cooling System.
ADVANCED SETUP Menu:
The Compressor mode is initiated by either the OAT going
above the DRYBLB SET setting or by the thermostat
initiating a call to cool when the damper is at 100 percent
open.The Economizer mode is controlled by the MAT
getting above the MAT SET setting while the OAT is below
the DRYBLB SET setting.
Setpoints Menu
CO2 ZERO = set to detectors start level
CO2 SPAN = detector's max level minus start level
Attach the sensor to the CO2 and R terminals (at customer
connections).
A customer-supplied occupancy sensor can also be added
to provide damper control based on occupied/unoccupied
conditions.
While the fans are not controlled by the controller, the Fan
mode is dependent on what state the system is in (OCC or
Y1 states will cause the damper to go to a LOW fan speed
damper setting, while Y2 or W states will cause the
controller to open the damper to the HIGH fan speed
damper setting). The Heating System mode requires an
input to the AUX2-1 terminal from the thermostat, and the
Cooling System mode requires an input to the Y2 IN and/or
the Y1 IN terminals from the thermostat.
Low Leak Economizer Units
Fan Failure Switch
To configure the JADE controller, set:
In electric heat mode, heaters will not be energized until
differential pressure switch proves airflow. The factory set
point is 0.07-inch w.c.
Note: When using any 0 to 10 Vdc CO2 sensor with the
JADE you will need to set CO2 ZERO to 400 ppm
and the CO2 SPAN to 1600 ppm in the ADVANCED
SETUP menu.

Installation
Note: Resistance in excess of 3 ohms per conductor
could cause component failure due to insufficient
AC voltage supply.
3. Be sure to check all loads and conductors for grounds,
shorts, and mis-wiring.
4. Do not run the AC low voltage wiring in the same
conduit with the high voltage power wiring.
Excessive three phase voltage imbalance between phases
will cause motors to overheat and eventually fail.
The maximum allowable voltage imbalance is 2 percent.
Measure and record the voltage between phases 1, 2, and
3 and calculate the amount of imbalance as follows:
% Voltage Imbalance = (100 x AV - VD) / AV where;
AV (Average Voltage) = Volt1 + Volt2 + Volt3 / 3

Conventional thermostat field wiring
Example: If the voltage readings of the supply power
measured 221, 230, and 227, the average volts would be:
(221 + 230 + 227) / 3 = 226 Avg.
•
VD (reading farthest from average) = 221
•
The percentage of Imbalance equals:
= (100 + 226 + 221) / 226 = 2.2%
The 2.2 percent imbalance in this example exceeds the
maximum allowable imbalance of 2.0 percent. This much
imbalance between phases can equal as much as a 20
percent current imbalance with a resulting increase in
motor winding temperatures that will decrease motor life.
If the voltage imbalance is over 2 percent, notify the proper
agencies to correct the voltage problem before operating
this equipment.
Electrical Phasing (Three Phase Motors)
The compressor motor(s) and the supply fan motor are
internally connected for the proper rotation when the
incoming power supply is phased as A, B, C.
Proper electrical supply phasing can be quickly determined
and corrected before starting the unit by using an
instrument like an Associated Research Model 45 Phase
Sequence Indicator. Follow the steps below.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
Voltage Imbalance
Three phase electrical power to the unit must meet
stringent requirements for the unit to operate properly.
Measure each leg (phase-to-phase) of the power supply.
Each reading must fall within the utilization range stamped
on the unit nameplate. If any of the readings do not fall
within the proper tolerances, notify the power company to
correct this situation before operating the unit.

Compressor Crankcase Heaters
NOTICE
Compressor Failure!
Failure to follow instruction below could result in
compressor failure.
Unit must be powered and crankcase heaters
energized at least 8 hours BEFORE compressors are
started.
Each compressor can be equipped with a crankcase
heater. The proper operation of the crankcase heater is
important to maintain an elevated compressor oil
temperature during the Off cycle to reduce oil foaming
during compressor starts. Oil foaming occurs when
refrigerant condenses in the compressor and mixes with
the oil. In lower ambient conditions, refrigerant migration to
the compressor could increase.
When the compressor starts, the sudden reduction in
crankcase pressure causes the liquid refrigerant to boil
rapidly causing the oil to foam. This condition could
damage compressor bearings due to reduced lubrication
and could cause compressor mechanical failures.
Before starting the unit in the Cooling mode, set the
system switch to the Off position and turn the main power
disconnect to the On position and allow the crankcase
heater to operate a minimum of 8 hours.
Before closing the main power disconnect switch, insure
that the System selection switch is in the Off position and
the Fan selection switch is in the Auto position.
RT-SVX083B-EN
Close the main power disconnect switch and the unit
mounted disconnect switch, if applicable.

backwards, it will not pump and a loud rattling
sound can be observed.
b. If the electrical phasing is correct, before
condemning a compressor, interchange any two
leads (at the compressor Terminal block) to check
the internal phasing. Refer to the following
illustration for the compressor terminal/phase
identification. Do not allow the compressor to
operate backwards for more than 5 seconds.
Operation for a period of time longer than this will
result in compressor damage.

Units
WARNING
5. Remove the belt tension gauge. The small O-ring now
indicates a number other than zero on the plunger force
scale. This number represents the force (in pounds)
required to give the needed deflection.
Rotating Components!
Failure to disconnect power before servicing could
result in rotating components cutting and slashing
technician which could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized.
6. Compare the force scale reading (Step 5) with the
appropriate force value listed in the Belt tension table.
If the force reading is outside the range, readjust the
belt tension.
Note: Actual belt deflection force must not exceed the
maximum force value shown in the Belt tension
measurement and deflection ranges table.
The fan belts must be inspected periodically to assure
proper unit operation. Replacement is necessary if the
belts appear frayed or worn. Units with dual belts require a
matched set of belts to ensure equal belt length.
7. Recheck the belt tension at least twice during the first 2
to 3 days of operation. Belt tension may decrease until
the new belts are run in.
Figure 15.
When removing or installing the new belts, do not stretch
them over the sheaves. Loosen the belts using the belt
tension adjustment bolts on the motor mounting base.
Belt tension gauge
Once the new belts are installed, using a Browning or
Gates tension gauge (or equivalent) illustrated in Figure
15, p. 24, adjust the belt tension as follows:
1. To determine the appropriate belt deflection:
a. Measure the center-to-center shaft distance (in
inches) between the fan and motor sheaves.
b. Divide the distance measured in Step 1a by 64; the
resulting value represents the amount of belt
deflection that corresponds to the proper belt
tension.
2. Set the large O-ring on the belt tension gauge at the
deflection value determined in Step 1b.

Maintenance
Coil Cleaning
Regular coil maintenance, including annual cleaning
enhances the unit’s operating efficiency by minimizing the
following:
•
Compressor head pressure and amperage draw
•
Evaporator water carryover
•
Fan brake horsepower
•
Static pressure losses
•
Airflow reduction
At least once each year, or more often if the unit is located
in a dirty environment, clean the condenser coils using the
instructions outlined below. Be sure to follow these
instructions as closely as possible to avoid damaging the
coils.
WARNING
Hazardous Chemicals!
Failure to follow this safety precaution could result in
death or serious injury. Coil cleaning agents can be
either acidic or highly alkaline and can burn severely
if contact with skin or eyes occurs.
Handle chemical carefully and avoid contact with
skin. ALWAYS wear Personal Protective Equipment
(PPE) including goggles or face shield, chemical
resistant gloves, boots, apron or suit as required. For
personal safety refer to the cleaning agent
manufacturer’s Materials Safety Data Sheet and follow
all recommended safe handling practices.
Microchannel (MCHE) Coils
NOTICE
Coil Damage!
Failure to follow instructions below could result in
coil damage.
DO NOT use any detergents with microchannel
condenser coils.
Use pressurized water or air ONLY, with pressure no
greater than 600psi.
For additional information regarding the proper
microchannel coil cleaning procedure, refer to RTSVB83*-EN
Due to the soft material and thin walls of the MCHE coils,
the traditional field maintenance method recommended for
Round Tube Plate Fin (RTPF) coils does not apply to
microchannel coils. Moreover, chemical cleaners are a risk
factor to MCHE due to the material of the coil. The
manufacturer does not recommend the use of chemical
cleaners to clean microchannel coils. Using chemical
cleaners could lead to warranty claims being further
evaluated for validity and failure analysis.
The recommended cleaning method for microchannel
condenser coils is pressurized water or air with a
nonpinpoint nozzle and an ECU of at least 180 with
pressure no greater than 600 psi. To minimize the risk of
coil damage, approach the cleaning of the coil with the
pressure washer aimed perpendicular to the face of the coil
during cleaning. Optimum clearance between the sprayer
nozzle and the microchannel coil is 1-inch to 3-inch.
