Features and
Benefits
Trane 3-D® Scroll Compressor
Simple Design with 70% Fewer Parts
Fewer parts than an equal capacity
reciprocating compressor means
significant reliability and efficiency
benefits. The single orbiting scroll
eliminates the need for pistons,
connecting rods, wrist pins, and valves.
Fewer parts lead to increased reliability.
Fewer moving parts, less rotating mass,
and less internal friction means greater
efficiency than reciprocating compressors.
Patented 3-D Scroll Compliance
Trane 3-D scroll compliance provides
important reliability and efficiency
benefits. 3-D compliance allows the
orbiting scrolls to touch in all three
dimensions, forming a completely
enclosed compression chamber that leads
to increased efficiency. In addition, 3-D
compliance means the orbiting scrolls only
touch with enough force to create a seal—
so there is no wear between the scroll
plates. The fixed and orbiting scrolls are
made of high strength cast iron—resulting
in less thermal distortion, less leakage,
and higher efficiencies. The most
outstanding feature of the scroll
compressor 3-D compliance is that
slugging will not cause failure. In a
reciprocating compressor, however, liquid
or dirt can cause serious damage.
Low Torque Variation
The 3-D scroll compressor has a very
smooth compression cycle with torque
variations that are only 30 percent of that
produced by a reciprocating compressor.
This means the scroll compressor
imposes very little stress on the motor for
greater reliability. Low torque variation
means reduced noise and vibration.
Suction Gas Cooled Motor
Compressor motor efficiency and
reliability are further optimized with this
design. Cool suction gas keeps the motor
cooler for longer life and better efficiency.
Proven DesignThroughTesting and
Research
With over twenty years of development
and testing,Trane 3-D scroll compressors
have undergone more than 400,000 hours
of laboratory testing and field operation.
This work combined with over 25 patents
makesTrane the worldwide leader in air
conditioning scroll compressor technology.
One of two matched scroll plates — the
distinguishing feature of the scroll
compressor.
The Chart above illustrates low torque
variation of 3-D Scroll compressors as
compared to a reciprocating compressor.

Application
Considerations
Self-Contained
transmit sound. In addition, small aspect
ratios will minimize potential“oil canning”
of the duct due to flow turbulence.
Return Air Ductwork
Self-Contained Acoustical
Duct the return air into the mechanical
equipment room. Connect ductwork to
the unit if local code dictates. The return
air ductwork must have an elbow inside
the equipment room. This elbow will
reduce sound transmissions through the
return duct. Extend the ductwork from
the elbow far enough to block the “line of
sight” to the exterior of the equipment
room. Use a minimum ductwork length
of 15 feet to the equipment room
exterior. Line the duct with two-inch,
three-pound density insulation. Use
multiple, small return ducts for better
acoustical performance to the occupied
space.
Recommendations
Successful acoustical results are
dependent on many system design
factors.
The flexible horizontal discharge plenum
option helps avoid complicated ductwork
transitions. Ductwork turning vanes
typically improve pressure drop but
degrade acoustical performance.
Following are general acoustical
recommendations. For more information,
or if there is concern about a particular
installation, contact a professional
acoustical consultant.
Recommended Maximum AirVelocities
The maximum recommended velocity
for the discharge air duct is 2,000 fpm.
The maximum recommended velocity
for the return air duct is 1,000 fpm. Limit
air velocities below these operating
points to minimize the risk of flow
turbulence that causes regenerated
noise. Using round supply duct and static
regain allows maximum discharge air
velocities up to 3,000 fpm. Lining round
supply duct also substantially lowers
frequency noise attenuation. However,
flow regenerated noise potential
Location and Orientation of the
Mechanical Equipment Room
Locate the equipment room adjacent to
stairwells, utility rooms, electrical closets,
and rest rooms if possible (See figure
below). This minimizes the acoustic
effects and risk of workmanship or
installation errors. Place the discharge
and return air ductwork over these less
acoustically sensitive areas, using vertical
or horizontal fresh air shafts. Consult code
requirements for fresh air and smoke
purge constraints.
Supply Air Ductwork
Insulate the supply air duct with two-inch,
three-pound density insulation. Extend
this lining at least 15 feet out from the
equipment room wall, keeping the duct
aspect ratio as small as possible.
Minimize large flat panels since they
increases dramatically at air velocities
over 3000 fpm.
Equipment Room Location and Orientation

PKG-PRC002-EN
Application
Considerations Self-Contained
Equipment Room Construction Options
The preferred equipment room wall
construction is concrete block. If this is not
feasible then a double stud offset wall is
suggested (See figure). This removes
physical contact that would transmit
sound through the equipment room wall
to the occupied space. Interweave
fiberglass insulation between the wall
studs. Use two layers of sheetrock on
each side of the wall.
Workmanship details are critical to
acoustical performance. Seal all wall and
floor penetrations by the ductwork, water
piping, and equipment room access
doors with a flexible material such as
caulk and/or gasketing to stop noise and
air leaks.
Double Stud Offset Wall with Interwoven Insulation
Locate the equipment room door away
from acoustically sensitive areas like
conference rooms. The door should
swing out of the equipment room, if
possible, so that the low pressure in the
equipment room pulls the door in to help
maintain a tight seal.

the building plumbing. The Signature
Waterside Economizer
The waterside economizer substantially
reduces the compressor energy
requirements because it uses the cooling
water before it enters the condensers.
Additional equipment room space is not
required since the coils are contained
within the overall unit dimensions.
Series self-contained unit is internally
isolated and does not require additional
isolation. However, ensure proper
system vibration isolation design

discharge.
prevents vibration transmission from the
building plumbing to the unit. Also be sure
to properly isolate the drain line.
Disadvantages include higher airside
pressure drop and a higher head on
condenser water pumps.
Static Pressure Versus Acoustics
Design the system to minimize the total
static pressure required from the self-
contained unit fan.Typically a change in
static pressure of only 0.5 inches can
reduce NC level by approximately 2 or 3
in the occupied space.
Condenser Water Piping
Piping Location and Arrangement
Provide at least 24 inches of clearance
between the piping and the unit for
service. Place the risers away from the
side of the unit if possible. Be sure to
allow sufficient space for valves and
unions between the piping and the self-
contained unit. Lay out condenser piping
in reverse returns to help balance the
system. This is accomplished by
equalizing the supply and return pipe
length. Multi-story buildings may use a
direct return system with balancing
valves at each floor. Install all heat
exchangers and most cooling tower
piping below the sump operating water
level to prevent overflow during unit and/
or system shut down.
The coils may be mechanically cleanable
(optional) for ease in maintenance versus
expensive and difficult chemical cleaning
methods.
Airside Economizer
The airside economizer substantially
reduces compressor, cooling tower, and
condenser water pump energy
requirements using outside air for free
cooling. It also reduces tower make up
water needs and related water
treatment.
Isolation Recommendations
Unit
The Signature Series unit fan and
compressors are internally isolated.
Therefore, external isolation is not
required. Consult a vibration specialist
before considering external or double
vibration isolation.
Disadvantages include building
requirements that locate the mechanical
room and self-contained unit toward an
exterior wall to minimize ductwork ,
building barometric control, or additional
air shafts. Also, airside economizers
require additional mechanical room
space.
Ductwork
Design duct connections to the unit using
a flexible material. Consult local codes for
approved flexible duct material to
prevent fire hazard potential.

Application
Considerations Self-Contained
Recommended Pump Location
utilize this feature, the building water
system must be capable of operating at
reduced water flow rates through the
self-contained units. It is imperative to
install variable volume pumps or an
external bypass in the water distribution
system.
strainer while allowing other units in the
system to remain in operation.
Locate pump downstream of the cooling
tower and upstream of the self-contained
unit. This provides smoother and more
stable unit operation.
Pressure Gauges
Install pressure gauges on the inlet and
outlet of the self-contained unit. Select
the gauge’s scale so that the unit design
operating point is approximately mid-
scale.
When the tower and pump are both roof
mounted, be sure to provide the
necessary net positive suction head
pressure to prevent cavitation. Raise the
tower or submerge the pump in a sump
to provide positive suction.To prevent an
on-line pump failure, use a standby pump
to avoid a complete system shutdown.
Several partial capacity pumps or
variable speed pumps may be used.
Review the economics of these alternate
pumping options.
Waterside Economizer Flow Control
Units equipped with waterside
economizer control valves can be set up
for variable or constant water flow.
Thermometers
Install thermometers on the condenser
water inlet and outlet lines to each unit for
system analysis.Trane Company
recommends using a thermometer
temperature range of 40 to 140 F, using
a 2 F temperature increment.
Use constant water flow setup on water
systems that are not capable of
unloading water supply to the unit. The
economizer and condenser valves will
operate in complement to one another to
provide continuous water flow.
Drains
The unit condensate drain is internally
trapped to offset the pressure differential
that exists during fan operation. Install a
trapped drain in the low point of the
mechanical equipment room floor to
collect water from cleaning operations.
Strainers and Water Treatment
Water strainers are required at the unit
inlet to eliminate potential unit damage
from dirty water. Specify a water basket-
type strainer to avoid an incorrect
stream strainer application. Untreated or
poorly treated water may result in
equipment damage. Consult a water
treatment specialist for treatment
recommendations.
Use variable water flow setup with water
flow systems that can take advantage of
pump unloading for energy savings.
Since non-cooling operation restricts
water flow during part load economizing
or condensing temperature control, it is
imperative to install variable volume
pumps or an external bypass in the water
distribution system.
Condensing Pressure Control
(Water-Cooled condensers)
Often cold condensing water applications
between 35 F (1.7 C) and 54 F (12.2 C)
require a condensing pressure control
valve. Any unit with variable-flow
waterside valves can modulate water
flow to maintain a user defined

Waterflow
Use 3 gpm/ton for optimum unit capacity
and efficiency. Use 2.5 or 2 gpm/ton to
reduce pump energy, cooling tower and
piping costs. However, these reduced
waterflows may impact unit capacity and
efficiency by one or two percent. Consult

Notes:
1. Compressors areTrane 3D® scroll.
2. EER and IPV are rated in accordance to the ARI Standard 340/360-93. Based on 80/67 F (26.7/19.4 C) to the evaporator coil,
nominal airflow and 85-95 F (29.4/35 C) condenser water.
3. All units operate with R-22. Units ships with full operating charge.
4. Maximum cfm limits are set to prevent moisture carryover on the evaporator coil.
5. Minimum cfm limits are set to ensure stable thermal expansion valve operation at low load conditions.
6. Filter sizes are for units without hot water or steam heating coils.

Standard IntelliPak® Unit
Control Features
All set-up parameters are preset from the
factory, requiring less start-up time during
installation.
The human interface panel is easy to
read and requires less time for building
maintenance personnel to learn to
interact with the unit. It features a clear
language display (in English, Spanish, or
French) that shows all of the self-
contained unit control parameters, such
as system on/off; demand limiting type;
night setback setpoints; and many other
setpoints. All adjustments are done
through the human interface key-pad.
Also the human interface panel allows
you to monitor diagnostic points such as;
sensor failures; supply airflow loss; and
inoperative refrigerant circuit. No special
tools are required for servicing the unit.
Diagnostics are held in memory, even
during power loss. This allows the
operator/servicer to diagnose the failure
root cause.
Human interface panel is
available as unit or
remote mounted.
Human Interface Panel (HI)
• DIAGNOSTICS allows the user to
review active and historical lists of
diagnostic conditions. A total of 49
different diagnostics can be read at the
human interface (HI) panel and the last
20 diagnostics can be held in an active
history buffer log at the HI panel.
• SETUP allows the user to edit control
parameters, sensor selections, setpoint
source selections, output definitions,
and numerous other points in this
menu. All points have factory preset
values to keep unnecessary editing to a
minimum.
• CONFIGURATION allows changing of
factory-preset unit configuration
information. This information can be
edited only if certain options are field-
installed or deleted from the unit. For
example, if aTrane communication
interface (TCI) module or ventilation
override module (VOM) were field-
installed, the unit configuration will
require editing to reflect those options
for proper unit operation.
IntelliPak® Unit Features
The human interface panel provides a
16-button keypad for monitoring, setting,
editing and controlling. The HI panel is
mounted in the unit’s main control panel,
accessible through the unit’s control panel
door.

units. Also, it can be used to purge smoke
or stale air.
This feature is available on all types of
factory-installed heat units and on units
with no heat. This function may still be
selected to support systems with heat
sources not provided by the self-
contained unit. At the conclusion of
unoccupied mode, the selected zone is
heated to the user-defined morning
warmup setpoint. The unit is then
released to occupied mode. There are
two types of morning warmup: full
capacity or cycling capacity.
•Supply fan – On
•Supply fan VFD – On (60 Hz)

• Full Capacity Morning Warmup (MWU)
Full capacity morning warmup uses full
heating capacity to heat the zone as
quickly as possible. Full heating capacity
is provided until the morning warmup
setpoint is met. At this point, the unit is
released to daytime mode.

• Cycling Capacity Morning Warmup
(MWU)
Cycling capacity morning warmup
provides gradual heating to overcome
“building sink” as the zone is heated.
Normal zone temperature control with
varying capacity is used to raise the zone
temperature to the MWU zone
temperature setpoint. Cycling capacity
MWU will operate until MWU setpoint is
reached or for 60 minutes. Then the unit
switches to occupied mode. Cooling will
suspend untill building load conditions
exceed the MWU setpoint of 3 F (1.7 C),
which is field adjustable.
•Exhaust fan (field-installed) - On
•Exhaust damper (field-installed) - Open
Note: Each system (cooling, exhaust,
supply air, etc.) within the unit can be
redefined in the field for each of the five
sequences, if required. Also the
definitions of any or all of the five
sequences may be locked into the
software by simple key strokes at the
human interface panel.
• EXHAUST sequence “C”
With the building’s exhaust fans running
and the unit’s supply fan off, the
conditioned space becomes negatively
pressurized. This is desirable for clearing
the area of smoke when necessary; i.e.
from an extinguished fire, to keep smoke
out of areas that were not damaged.
•Supply fan – Off
•Supply fan VFD – Off (0 Hz)

•VO relay – Energized
Note: When using the morning warmup
option in a heating/cooling self-contained
unit in aVAV system, it is important to
maintain airflow through the unit. This
can be accomplished by electrically tying
theVAV boxes to theVAV drive max
output relay contacts on the unit’s RTM
module board or by using changeover
thermostats. Either of these methods will
assure adequate airflow through the unit
and satisfactory heating.
Ventilation Override (VOM) Option
The user can customize up to five
different override sequences for
purposes of ventilation override control. If
more than one VOM sequence is being

Comparative Enthalpy Control of Airside
Economizer Option
Occupied/Unoccupied Switching
There are four ways to switch occupied/
unoccupied:
An optional comparative enthalpy
system is used to control the operation of
the economizer and measures the
temperature and humidity of both return
air and outside air to determine which
source has lower enthalpy.This system
allows true comparison of outdoor air
and return air enthalpy by measurement
of outdoor and return air temperatures
and humidities.

Compressor Lead/Lag
• Factory MountedTime Clock
A time clock can control the
occupied/unoccupied status of the
self-contained unit.
Compressor lead/lag is a user-selectable
feature through the human interface
panel available on all units. After each
request for compressor operation, the
lead refrigeration circuit or compressor
switches, thereby causing a more
equitable or balanced run time among
compressors.
• GBAS Binary Outputs
Each of the five (5) relay outputs can be
mapped to any/all of the available
diagnostics.
Timed Override Activation - ICS
This function is operational whenever the
unit’s RTM module board is used as the
zone temperature sensor source, which
can be set at the human interface panel.
When this function is initiated by the push
of the override button on the zone sensor,
the unit will switch to the occupied mode.
Unit operation (occupied mode) during
timed override is terminated by a signal
from Tracer®.
• Demand Limiting Binary Input
This function is operational on units with a
GBAS and is used to reduce electrical
consumption at peak load times. There
are two types of demand limiting, 50%
and 100%. When demand limiting is
needed, mechanical cooling and heating
operation are either partially (50%), or
completely disabled (100%) to save
energy.The demand limit definition is
user definable at the human interface
panel. Demand limit binary input accepts
a field supplied switch or contact closure.
When the need for demand limiting has
been discontinued, the unit’s cooling/
heating functions will again become fully
enabled.
Emergency Stop Input
A binary input is provided on the unit’s
RTM module board for installation of a
field-provided switch or contacts to
immediatly shutdown all unit functions.
Water Flow Control
With compatible piping configurations,
the unit can be configured to provide:
1) Constant water flow with basic or
intermediate piping or 2)Variable water
flow with intermediate piping only.
Timed OverrideActivation - Non-ICS
This function is active whenever the unit’s
RTM module board is selected as the
zone temperature source, which can be
set at the human interface panel. When
this function is initiated by the push of the
override button on the zone sensor, the
unit will switch to the occupied mode.
Automatic cancellation of the timed
override mode occurs after three hours
of operation.
Constant water flow is for condenser
pumping systems that are not capable of
unloading the water-pumping system.
Variable water flow maximizes energy
saving by unloading the water pumping
system.
Evaporator Coil Frost Protection
FROSTAT™
A temperature sensor on the evaporator
is used to determine if the coil is getting
close to a freezing condition. Mechanical
cooling capacity is shed as necessary to
prevent icing.
Low Ambient Compressor Lockout
This function will lock out the compressor
if the outdoor air temperature is below
the low ambient compressor lock-out
temperature setpoint when using a field-
installed outside air sensor.This setpoint
is adjustable at the human interface
panel. Compressors will lock out when
outdoor air temperature falls below that
selected temperature and will start again
Head Pressure Control
• Water-Cooled Condensers
Units that are set up for variable water
flow will modulate a water valve to
maintain a user-defined condensing
temperature setpoint. Condensing
temperature will be referenced utilizing
factory installed sensors located at each
condenser.
The FROSTAT™ system eliminates the
need for hot gas bypass and adds a
suction line surface temperature sensor
mounted near the TXV bulb location to
shut off the cooling when coil frosting
conditions occur.The supply fan is not

• Air-Cooled Condensers
Inlet guide vane assemblies installed on
the supply fan inlet regulate fan capacity
and limit horsepower at lower system air
requirements. When in any position other
than full open, the vanes pre-spin the air
in the same direction as supply fan
rotation. As the vanes approach the full-
closed position, the amount of “spin”
induced by the vanes increases at the
same time that intake airflow and fan
horsepower diminish. The inlet guide
vanes will close when the supply fan is
off.
Bypass control is offered as an option to
provide full nominal airflow in the event
of drive failure. Manual bypass is initiated
at the human interface panel. When in
the bypass mode,VAV boxes will need to
be fully opened. The self-contained unit
will control heating and cooling functions
to maintain setpoint from a user defined
zone sensor. Supply air static pressure
limit will be active in this mode.
Condenser fans will stage per a user-
defined setting. If the condenser is
equipped with head pressure control (air
modulation on last stage of condenser
capacity), the condenser airflow will
modulate to maintain condensing
temperature setpoint. Condensing
temperature is determined by sensors
located at each condenser coil.
Water Purge
Supply Air Static Pressure Limit
This user-definable feature allows the
user to select a purge schedule to
automatically circulate water through the
economizer and condensers periodically
during non-operational times. This allows
fresh chemicals to circulate in waterside
heat exchangers.
The opening of the inlet guide vanes and
VAV boxes are coordinated during unit
start up and transition to/from occupied/
unoccupied modes to prevent
Variable Frequency Drive (VFD) Control
Variable frequency drives are driven by a
modulating 0-10 vdc signal from the RTM
module. A pressure transducer
measures duct static pressure, and the
VFD adjusts the fan speed to maintain the
supply air static pressure within an
adjustable user-defined range. The range
is determined by the supply air pressure
setpoint and supply air pressure
overpressurization of the supply air
ductwork. However, if for any reason the
supply air pressure exceeds the user-
defined supply air static pressure limit
that was set at the human interface
panel, the supply fan/VFD is shut down
and the inlet guide vanes close. Then unit
will attempt to restart, up to three times. If
the overpresssurization condition still
occurs on the third restart, the unit shuts
down and a manual reset diagnostic sets
and displays at the human interface
panel.

Zone Temperature Control
Unit Sequence Of Operation
When the system mode is auto, the mode
will change to cooling or heating as
necessary to satisfy the zone cooling and

Note that the airside economizer will only
function freely if ambient conditions are
below the enthalpy control settings or
below the return air enthalpy if unit has
comparative enthalpy installed. If outside
air is not suitable for “economizing,” the
fresh air dampers drive to the minimum

Unoccupied ZoneTemperature Control
Cooling and Heating
Both cooling and heating modes can be
selected to maintain unoccupied zone
temperature deadbands. For unoccupied
periods, heating, economizer operation,
or compressor operation can be
selectively locked out at the human
interface panel.
At outdoor air conditions above the
enthalpy control setting, only mechanical
cooling is used and the fresh air dampers
remain at minimum position.
Waterside economizing enables when
the unit’s entering water temperature is
below the unit’s entering mixed air
temperature by 4 F plus the user
adjustable economizer approach
temperature. The approach temperature
default is 4 F and is adjustable from 0-9 F
at the human interface (HI) panel.
Waterside economizing disables when
the unit’s entering water temperature is
not below the unit’s entering mixed air
temperature by at least the water
economizer approach temperature. The
approach temperature defaults to 4 F and
is adjustable from 0-9 F at the HI. The
economizer acts as the first stage of
cooling. If the economizer is unable to
maintain the zone temperature setpoint,
the compressor module will bring on
compressors as required to meet the
setpoint.
If the unit does not include an airside
economizer, only mechanical cooling will
operate to satisfy cooling requirements.
Heating: Electric
On units with electric heating, the zone
temperature can be controlled to a
heating setpoint during the occupied
mode by cycling a single stage electric
heater. Interface is provided for field
supplied single stage electric heat. The
zone temperature heating setpoint and
deadband are user defined at the human
interface panel.
Heating: Hot Water or Steam
On units with hot water or steam heating,
the zone temperature can be controlled
to a heating setpoint during the occupied
mode. The zone temperature heating
setpoint and deadband are user defined
at the human interface panel.

end, the heating valve modulates open to
maintain the minimum supply air

Supply Air Setpoint Reset
Supply air reset can be used to adjust the
supply air temperature setpoint on the
basis of a zone temperature or outdoor
air temperature. Supply air reset
adjustment is available from the human
interface panel for supply air heating and
supply air cooling control.
Daytime Warmup
During occupied mode, if the zone
temperature falls to a preset, user-
