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
Indicates a potentially hazardous situation which, if
not avoided, could result in death or serious injury.
CAUTION
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.
NOTICE
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-
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 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
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 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.

Overview
Note: One copy of this document ships inside the control
panel of each unit and is customer property. It must
be retained by the unit’s maintenance personnel.
This manual describes proper installation, operation, and
maintenance procedures for commercial self-contained
systems. By carefully reviewing the information within this
manual and following the instructions, the risk of improper
operation and/or component damage will be minimized. It
is important that periodic maintenance be performed to
help assure trouble free operation. A maintenance
schedule is provided at the end of this manual. Should
equipment failure occur, contact a qualified service
organization with qualified, experienced HVAC technicians
to properly diagnose and repair this equipment.
This manual covers installation, operation and
maintenance of 20-110 ton Signature Series Commercial
Self Contained products with R-410A refrigerant.
R-410A Compressors
• Use crankcase heaters which must be energized 24
hours prior to compressor start.
• Contain POE oil which readily absorbs potentially
damaging moisture from air.
• Control box includes a phase monitor to detect phase
loss, line voltage imbalance and reversal.
Refer to previous IOM versions for R-407C and R-22 units,
or contact your local Trane representative.
Refer to IntelliPak™ controls programming guide (PKG-
SVP01*-EN).
Signature Series Self-Contained
Unit Components
Commercial self-contained units are complete HVAC
systems used in floor-by-floor applications. Units are easy
to install because they feature:
• A single point power connection.
• Factory-installed and tested controls.
• A single water point connection.
• Factory-installed options.
• An internally trapped drain connection.
Note: Refer to the following figure 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
external equalizing line, discharge line schrader valve,
suction line schrader valve and high and low pressure
cutout switches. The water-cooled condensers are shell
and tube type with an internal subcooler. Condensers are
available as mechanically or chemically cleanable.
All units include liquid line service valves for each circuit as
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.

Standard Controls
Standard controls supplied with the unit include the human
interface (HI) panel with unit control module (UCM). All
basic setup parameters are preset from the factory.
Human Interface Panel
The HI is unit mounted and accessible without opening the
unit’s front panel. It allows easy setpoint adjustment using
the HI keypad. The HI displays all unit operating
parameters and conditions in a clear language display,
which can be configured for either English, French, or
Spanish.
The optional remote human interface (RHI) will control up
to four self-contained units, each containing an
interprocessor communications bridge (IPCB). It has all the
same features as the unit-mounted HI except for the
service mode.
For more information on setpoint defaults and ranges and
unit programming, see the Self-Contained Programming
Guide, PKG-SVP01*-EN. A copy ships with each unit.
Unit Control Module
The UCM provides “smart” unit control with safety features
and control relays for pumps, dampers, etc. The Signature
Series self-contained unit is controlled by a microelectronic
control system that consists of a network of modules.
Modular Series self-contained unit is controlled by
microelectronic control system consisting of a network of
modules.These modules are referred to as unit control
modules (UCM). In this manual, 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., economizing, mechanical cooling,
heating, ventilation.
See the Owner’s section of this manual for a detailed
description of each module’s function.

Figure 2. Right side view of unit 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. Morning warm-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.

Pre-Installation
Receiving
Receiving Checklist
Complete the following checklist immediately after
receiving unit shipment to detect possible shipping
damage:
• Inspect individual cartons before accepting. Check for
rattles, bent carton corners, or other visible indications
of shipping damage.
• If a unit appears damaged, inspect it immediately
before accepting the shipment. Make specific notations
concerning the damage on the freight bill. Do not refuse
delivery.
• Inspect the unit for concealed damage before it is
stored and as soon as possible after delivery. Report
concealed damage to the freight line within the allotted
time after delivery. Check with the carrier for their
allotted time to submit a claim.
• Do not move damaged material from the receiving
location. It is the receiver’s responsibility to provide
reasonable evidence that concealed damage did not
occur after delivery.
• Do not continue unpacking the shipment if it appears
damaged. Retain all internal packing, cartons, and
crate. Take photos of damaged material if possible.
• Notify the carrier of the damage immediately by phone
and mail. Request an immediate joint inspection of the
damage by the carrier and consignee.
Note: Notify your Trane representative of the damage and
arrange for repair. Have the carrier inspect the
damage before making any repairs to the unit.
Ship-Separate Accessories
Field-installed sensors ship separately inside main control
panel of the unit. Extra filters, sheaves, and belts ship in
the fan motor section of the unit. Condenser plugs, spring
isolators, and Iso-pads ship stored in the bottom left side of
the unit.
Contractor Installation Responsibilities
Complete the following checklist before beginning final unit
installation:
• Verify the unit size and tagging with the unit nameplate.
• Make certain the floor or foundation is level, solid, and
sufficient to support the unit and accessory weights.
Level or repair the floor before positioning the unit if
necessary.
• Allow minimum recommended clearances for routine
maintenance and service. Allow space at end of the
unit for shaft removal and servicing. Refer to the unit
submittals for dimensions. See also the “Service
Clearances” section in the Dimensional Data chapter.
• Allow three fan diameters above the unit for the
discharge ductwork. Return air enters the rear of the
unit and conditioned supply air discharges through the
top.
• Electrical connection knockouts are on the top, left side
of the unit.
• Allow adequate space for piping access and panel
removal. Condenser water piping, refrigerant piping,
and condensate drain connections are on the lower left
end panel.
Note: Unit height and connection locations will change
if using vibration isolators. The unit height may
increase up to 5-7/8” with spring type isolators.
• Electrical supply power must meet specific balance and
voltage requirements as described in chapter
“Electrical Installation”.
• The installer is responsible for providing a condenser
main, standby water pump, cooling tower, pressure
gauges, strainers, and all components for waterside
piping. See “Water Piping,” p. 34 for general waterside
recommendations.
Unit Inspection
To protect against loss due to damage incurred in transit,
perform inspection immediately upon receipt of the unit.
Exterior Inspection
If the job site inspection reveals damage or material
shortages, file a claim with the carrier immediately. Specify
the type and extent of the damage on the bill of lading
before signing. Notify the appropriate sales representative.
Important: Do not proceed with installation of a damaged
unit without sales representative’s approval.
• Visually inspect the complete exterior for signs of
shipping damages to unit or packing material.
• Verify that the nameplate data matches the sales order
and bill of lading.
• Verify that the unit is properly equipped and there are
no material shortages.
• Verify that the power supply complies with the unit
nameplate specifications.
Inspection for Concealed Damage
Visually inspect the components for concealed damage as
soon as possible after delivery and before it is stored.
If concealed damage is discovered:
• Notify the carrier’s terminal of the damage immediately
by phone and by mail.
• Concealed damage must be reported within 15 days.
• Request an immediate, joint inspection of the damage
with the carrier and consignee.
• Stop unpacking the unit.

SCXF-SVX01T-EN 19
• Do not remove damaged material from receiving
location.
• Take photos of the damage, if possible.
• The owner must provide reasonable evidence that the
damage did not occur after delivery.
Repair
Notify the appropriate sales representative before
arranging unit installation or repair.
Important: Do not repair unit until the damage has been
inspected by the carrier’s representative.
Unpacking
Commercial self-contained units ship assembled with
protective coverings over the coil and discharge openings.
Figure 3, p. 19 illustrates a typical shipping package.

Unit Protective Covers
Remove shipping protection coverings from human
interface panel (HI) at control panel, filter box (or air inlet
opening), discharge air opening, and optional variable
frequency drive (VFD).
Supply Fan Isolators
Remove the shipping channels and four fan mounting bolts
from beneath the fan. Open both fan compartment doors to
access the channels.
Notes:
• There are six fan mounting points for 40-110
ton units.
• The 20 to 38 ton units use neoprene isolators,
and 40 to 110 ton units use spring isolators.
