Introduction

Read thismanual 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

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

CAUTIONs

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 situationthat 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-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.

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 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
FOR INTENDED VOLTAGE.

Failure to follow instructions could result in death or
serious injury.

WARNING

Refrigerant under High Pressure!

System contains oil and refrigerant under high
pressure. Recover refrigerant to relieve pressure before
opening the system. See unit nameplate for refrigerant
type. Do not use non-approved refrigerants, refrigerant
substitutes, or refrigerant additives. Failure to recover
refrigerant to relieve pressure or the use of non­approved refrigerants, refrigerant substitutes, or
refrigerant additives could result in an explosion which
could result in death or serious injury or equipment
damage.

WARNING

Hazardous Voltage w/Capacitors!

Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives or
other energy storing components provided by Trane or
others, refer to the appropriate manufacturer’s literature
for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged. Failure to disconnect power
and discharge capacitors before servicing could result in
death or serious injury.

For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN

NOTICE:

Use Copper Conductors Only!

Unit terminals are not designed to accept other types
of conductors. Failure to use copper conductors could
result in equipment damage.

General Data

Signature Series Self-Contained Unit Components

Commercial self contained units are complete HVAC
systems used infloor-by-floor applications. Units are easy
to install because they feature a single point power
connection, factory installed and tested controls, single
water point connection, factory installed options, and an
internally trapped drain connection.

See Figure 1, p. 9 and Figure 2, p. 10 for typical unit
components.

The hermetically sealed scroll compressor motors utilize

internal motor protection and time delays to prevent
excessive cycling.

Water-cooled units have 2-6 refrigerant circuits and ship

with a full refrigerant and oil charge. Each circuit includes
filter drier, pressure relief valve, sight glass/moisture
indicator, thermal expansion valve with sensing bulb and

and tube type with an internal subcooler. Condensers are
available as mechanically or chemically cleanable.

Air-cooled units have two circuits and ship with oil and a
dry nitrogen holding charge.Therefore, air-cooled units
require field piping refrigerant connections to an air­cooled condensing unit and charging. Each circuit includes
filter drier (field installed), sight glass/moisture indicator,
thermal expansion valve with sensing bulb and external
equalizing line, discharge line schrader valve, suction line
schrader valve, high and low pressure cutout switches,
discharge line check valve and liquid line solenoid valve.

All units includeliquid line servicevalves for each circuitas
standard (suction and discharge service valves are
optional).

Evaporator fans are double width, double inlet and
forward curved with fixed pitch belt drive assembly.

Variable frequency drives are optional. EISA efficiency

open drip proof (ODP) and totally enclosed fan cooled
(TEFC) motor options are available.

Optional Controls

Optional controls include a disconnect switch, dirty filter
switch, water flow switch (water-cooled only), supply air
temperature reset, or external setpoint inputs. Daytime
heating is available on units with electric, steam, or hot
water heat control options. Morningwarm-up operation is
available on all units.

The static pressure probe, zone night heat/morning warm-

up, supply air temperature reset sensor options ship
separate inside the unit control panel for field installation.
For more detailed information on the unit control options,
see the Owner’s section of this manual.

Unit Nameplate

The unit nameplate identifies the unit model number,

appropriate service literature, and wiring diagram
numbers. It is mounted on the left end of the unit control
panel.

Unit Control Module

The UCM provides “smart” unit control with safety

features and control relays for pumps, dampers, etc.The
Signature Series IntelliPak self-contained unit is controlled
by a microelectronic control system that consists of a
network of modules.These modules are referredto as unit
control modules (UCM). In thismanual, the acronym UCM
refers to the entire control system network.

These modules perform specific unit functions using

proportional/integral control algorithms.They are
mounted in the unit control panel and are factory wired to
their respective internal components. Each module
receives and interprets information from other unit
modules, sensors, remote panels, and customer binary
contacts to satisfy the applicable request; i.e.,

2. Operating charge is for entire system, including air–cooled self–contained, remote air–cooled condenser, and 25 feet of interconnecting refrigerant

piping.

3. See Table 25, p. 36 for additional charge required for alternate interconnecting piping lengths.

4. At conditions of 95° F (35° C), condenser storage capacity is 95% full.

5. To determine the correct amount of refrigerant needed for a particular application, reference the Trane Reciprocating Refrigeration Manual.

Unit Handling Procedure

WARNING

Improper Unit Lift!

Test lift unit approximately 24 inches to verify proper

center of gravity lift point. To avoid dropping of unit,
reposition lifting point if unit is not level. Failure to
properly lift unit could result in unit dropping and
possibly crushing operator/technician which could
result in death or serious injury and possible
equipment or property-only damage.

1. Use spreader bars to avoid unit damage.

2. Spreader bar must be a minimum of 11 feet for 20-85
ton units and 12 feet for 90-110 tons. Chains must not
bear on top of unit.

3. Do not use hooks to lift unit. Do not hook into open
channels

Installation Preparation

Before installing the unit, perform the following
procedures to ensure proper unit operation.

1. Position the unit and skidassembly inits final location.

2. Test lift the unit to determine exact unit balance and
stability before hoisting it to the installation location.
See “Unit Handling Procedure,” p. 28 for proper
rigging procedures and cautions.

3. Remove the skids from under the unit. See Figure 3,

p. 18. Refer to the “Skid Removal” section. If you find

internal damage, file a claim immediately to the
deli

vering carrier.

4. Remove the protective shipping covers from the unit.

5. Verify isolators are properly tightened for operation.

Unit Vibration Isolator Option

Important: Vibration isolation is not necessary for the

unit since the factory internally isolates the
fan and compressors, thus creating double
isolation.Trane strongly recommends that
you consult a vibration specialist when
considering double isolation.In general,

Trane does not recommend double-

isolation.

If job requirements dictate unit isolators, use a housed­spring isolator with a locating pin. Factory-provided unit
isolators are type CP and indicate the spring number on
the outer housing.See Figure 20, p. 29. Set the spring-type
vibration isolators inposition before completing electrical,
piping, or duct connections.The 20-38 ton units require
four isolators per unit, and the 40-80 ton units require six
isolators per unit. Reference the isolator placement sheet
that ships with the isolators to indicate proper placement.

Unit Isolator Installation Procedure

Follow the procedure below to install isolators:

1. Position the isolators under the unit base referring to
the isolator placement sheet that ships with the unit
isolators. Lift one end of the unit at a time to position
the isolators. Fasten the isolators to the floor using
anchor bolts.

2. Level the unit by adjusting the isolator heights. Unit
weight
isolators to rest on the lower housing. Maintain
clearances between 1/4 and 1/2”.To increase the
clearance, lift the unit off the isolator and turn the
leveling bolt counterclockwise. Verify that the unit is
level and the housing clearances are correct.The
maximum allowable difference between isolator
heights is 1/4”. Shim as required under the isolators.

Note: The unit is equipped with a positively sloped drain

Duct Connections

Return air enters the rear of the unit and conditioned
supply air discharges through the top. Attach supply air
ductwork directly to the unit’s top panel, around the fan
discharge opening. A duct collar is not provided.

Note: Units equipped with flexible horizontal discharge

plenum option may include a duct collar when
holes are factory cut. If discharge openings are
field-cut, refer to the “Plenum Installation” section.

Install all airducts according to the National Fire Protection

Association standards for the “Installation of Air

Conditioning and Ventilation Systems other than
ResidenceType (NFPA 90A) and ResidenceType Warm Air
Heating and Air Conditioning Systems (NFPA 90B).

Make duct connections to the unit with a flexible material
such as heavy canvas. If a fire hazard exists,Trane

recommends using Flexweave 1000, type FW30 or
equivalent canvas. Use three inches for return duct and
three inches for discharge duct. Keep material loose to
absorb fan vibration.

Note: Compressors and fan assembly are internally

isolated. External isolation devices (spring
mounting isolators) are at discretion of a vibration
specialist consulted by building or HVAC system
designer.

• If using return ductwork to the unit, secure it with three
inches of flexible duct connector.

• Extend discharge duct upward without change in size

direction for at least three fan diameters.

or

• Use 3” flexible duct connection on discharge
ductwork.

Run the ductwork straight from the opening for a minimum of
three

fan diameters. See Figure 21, p. 30. Extend remaining
ductwork as far as possible without changing size or direction.
Do not make abrupt turns or transitions near the unit due to
increased noise and excessive static losses. Use elbows with
splitters or turning vanes to minimize static losses.

Poorly constructed turning vanes may cause airflow generated
noise. Align the fan outlet properly with the ductwork to
decrease noise levels in the duct and to increase fan
performance.To complete trunk ductwork to the VAV terminal
units, refer to the VAV box manuals for specific requirements.
Check total external static pressures against fan characteristics
to be sure the required airflow is available throughout the
ductwork.

To achieve maximum acoustical performance, minimize the

duct static pressure setpoint

Plenum

Figure 22. Correct plenum insulation placement

Before installing plenum, attach insulation strip that ships
with plenum. See Figure 22, p. 30 for proper insulation
location. Align plenum front with control panel side of
unit. Using strips and screws provided, secure plenum to
unit.Treat field-cut holes to prevent fiberglass from
entering the airstream.

Note: Plenum insulation must be applied properly to

prevent air bypass around the plenum. See

Figure 22, p. 30.

Dashed line indicates correct insulation placement.
