SAFETY WARNING

Only qualified personnel should install and service the equipment. The installation, starting up, and

servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific

knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could

result in death or serious injury. When working on the equipment, observe all precautions in the literature

and on the tags, stickers, and labels that are attached to the equipment.

and Maintenance

Warnings, Cautions and Notices

Warnings, Cautions and Notices. Note that warnings,

cautions and notices appear at appropriate intervals

throughout this manual. Warnings are provide to alert

installing contractors to potential hazards that could result

in death or personal injury. Cautions are designed to alert

personnel to hazardous situations that could result in

personal injury, while notices indicate a situation that

could result in equipment or property-damage-only

accidents.

Your personal safety and the proper operation of this

machine depend upon the strict observance of these

precautions.

Read this manual thoroughly before operating or servicing

this unit.

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.

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.

ATTENTION: Warnings, Cautions and Notices appear at

appropriate sections throughout this literature. Read

these carefully:

WARNING

Indicates a potentially hazardous

situation which, if not avoided, could

result in death or serious injury.

CAUTIONs

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

WARNING

Proper Field Wiring and Grounding

Required!

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. Failure to

follow code 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 non-

approved refrigerants, refrigerant substitutes, or

refrigerant additives could result in an explosion which

could result in death or serious injury or equipment

damage.

WARNING

Model Number Description

Nameplates

The RTAC outdoor unit nameplates are applied to the

exterior of the Control Panel. A compressor nameplate is

located on each compressor. When the unit arrives,

compare all nameplate data with ordering, submittal, and

shipping information.

Outdoor Unit Nameplate

See Figure 1, p. 8 for a typical unit nameplate.The outdoor

unit nameplate provides the following information:

• Unit model and size description.

• Unit serial number.

• Identifies unit electrical requirements.

• Lists correct operating charges of R-134a and

refrigerant oil (Trane OIL00048).

• Lists unit test pressures.

• Identifies installation, operation and maintenance and

service data literature (Pueblo).

• Lists drawing numbers for unit wiring diagrams

(Pueblo).

Model Number Coding System

The model numbers for the unit and the compressor are

composed of numbers and letters that represent features

of the equipment. Shown in the following table is a sample

of typical unit model number and the coding system for

each.

Each position, or group of positions, in the model number

is used to represent a feature. For example, in the first

table, position 08 of the unit model number, UnitVoltage,

contains the number “4”.A 4 in this position means that the

unit voltage is 460/60/3.

Unit Model Number. An example of a typical unit

model number (M/N) is:

RTAC 350A UA0N NAFN N1NX 1TEN NN0N N01N

Model number digits are selected and assigned in

accordance with the definitions as listed in “Unit Model

Number,” p. 9.

Compressor Nameplate

The compressor nameplate provides following

information:

• Compressor model number. See “Compressor Model

Number,” p. 10.

• Compressor serial number. See“Compressor Serial

Number,” p. 10.

• Compressor electrical characteristics.

• Utilization range.

• Recommended refrigerant.

General Data

Unit Description

The 140 - 500 ton Model RTAC units are helical-rotary type,

air-cooled liquid chillers designed for installation

outdoors.The compressor circuits are completely

assembled, hermetic packages that are factory-piped,

wired, leak-tested, dehydrated, and tested for proper

control operation before shipment.

Chilled water inlet and outlet openings are covered for

shipment. Each compressor has a separate compressor

motor starter.The RTAC series featuresTrane’s exclusive

Adaptive Control ™ logic, which monitors the control

variables that govern the operation of the chiller unit.

Adaptive Control logic can adjust capacity variables to

avoid chiller shutdown when necessary, and keep

producing chilled water.The units feature two

independent refrigerant circuits. Compressor unloaders

are solenoid actuated and oil pressure operated. Each

refrigerant circuit is provided with filter, sight glass,

electronic expansion valve, and charging valves.The

shell-and-tube type evaporator is manufactured in

accordance with ASME standards or other international

codes. Each evaporator is fully insulated and is equipped

with water drain and vent connections. Packaged units

have heat tape protection to - 20°F (-28.9°C) as standard.

As an option, a convenience outlet can be supplied.

Note: Packaged units are factory charged with refrigerant

and oil.

Accessory/Option Information

Check all the accessories and loose parts which are

shipped with the unit against the shipping list. Included in

these items will be water vessel drain plugs, rigging and

electrical diagrams, and service literature, which are

placed inside the control panel and/or starter panel for

shipment.

Isolator Shipping Location

If optional neoprene isolators (model number digit 33) are

ordered with unit, they are shipped mounted on the unit.

See Figure 3 and Figure 4.
