must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
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
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.
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

Model Number Description
Nameplates
The RTWD/RTUD unit nameplates are applied to the
exterior surface of the control panel door.
A compressor nameplate is located on each compressor.
Unit Nameplate
See Figure 1. Unit nameplate includes the following:
•Unit model and size descriptor.
•Unit serial number.
•Identifies unit electrical requirements.
•Lists correct operating charges of R-134a and Oil 48.

Model Number Coding System
Model numbers for unit and compressors are comprised
of numbers and letter which represent equipment
features.
See “RTWD Model Number,” p. 7and “Compressor Model
Number,” p. 8 for details.
Each position, or group of positions, in a number or letter
is used to represent a feature.For example, from the chart,
we can determine that “F” in digit 8 of unit model number
indicates unit voltage is 460/60/3.
ASME Nameplate
The ASME nameplate is different for the evaporators,
condensers (RTWD only) and oil separators.The
evaporator nameplate is located on the left portion of the
shell.The insulation over the nameplate is intentionally
left unglued, for ease in viewing the nameplate.
The condenser nameplate is on the backside of the
condenser below circuit 2 compressor.

The RTWD units are helical-rotary type, water-cooled,
liquid chillers, designed for installation indoors.The units
have 2 independent refrigerant circuits, with one
compressor per circuit.The RTWD units are packaged with
an evaporator and condenser.
Note: Each RTWD unit is a completely assembled,
hermetic package that is factory-piped, wired, leak-
tested, dehydrated, charged and tested for proper
control operations prior to shipment.The chilled
water inlet and outlet openings are covered for
shipment.
The RTWD series featuresTrane's exclusive Adaptive
Control logic with CH530 controls. It monitors the control
variables that govern the operation of the chiller unit.
Adaptive Control logic can correct these variables, when
necessary, to optimize operational efficiencies, avoid
chiller shutdown, and keep producing chilled water.
Compressor unloaders are solenoid actuated. Each
refrigerant circuit is provided with filter, sight glass,
electronic expansion valve, and charging valves on the
RTWD.
The evaporator and condenser are manufactured in
accordance with ASME standards.The evaporator is fully
insulated. Both evaporator and condenser are equipped
with water drain and vent connections.
The RTUD units are helical-rotary type compressor
chillers, designed to be most effective when used with the
Levitor II air-cooled condenser.The RTUD unit consists of
an evaporator, two helical rotary compressors (one per
circuit), oil separators, oil coolers, liquid line service
valves, sightglasses, electronic expansion valves and
filter.The discharge line leaving the oil separator and
liquid line entering the filters are capped and brazed. The
unit ships with a full charge of oil and a nitrogen holding
charge.
Accessory/Options Information
Check all the accessories and loose parts which are
shipped with the unit against the original order. Included
in these items will be water vessel drain plugs, rigging
diagrams, electrical diagrams, and service literature,
which are placed inside the control panel and/or starter
panel for shipment. Also check for optional components,
such as flow switches and isolators.

Pre-Installation
Inspection Checklist
When the unit is delivered, verify that it is the correct unit
and that it is properly equipped. Compare the information
which appears on the unit nameplate with the ordering
and submittal information. See “Model Number
Descriptions,” p. 7.
Inspect all exteriorcomponents for visibledamage. Report
any apparent damage or material shortage to the carrier
and make a “unit damage” notation on the carrier's
delivery receipt. Specify the extent and type of damage
found and notify the appropriateTrane Sales Office.
Important:Do not proceed with installation of a
damaged unit without sales office approval.
To protect against loss due to damage incurred in transit,
complete the following checklist upon receipt of the unit.
•Inspect the individual pieces of the shipment before
accepting the unit. Check for obvious damage to the
unit or packing material.
•Inspect the unit for concealed damage as soon as
possible after delivery and before it is stored.
Concealed damage must be reported within 15 days.
•If concealed damage is discovered, stop unpacking the
shipment. Do not remove damaged material from the
receiving location.Take photos of the damage, if
possible.The owner must provide reasonable
evidence that the damage did not occur after delivery.
•Notify the carrier's terminal of the damage
immediately, by phone and by mail. Request an
immediate, joint inspection of the damage with the
carrier and the consignee.
•Notify theTrane sales representative and arrange for
repair. Do not repair the unit, however, until damage is
inspected by the carrier's representative.
Unit Storage
If the chiller is to be stored for more than one month prior
to installation, observe the following precautions:
•Do not remove the protective coverings from the
electrical panel.
•Store the chiller in a dry, vibration-free, secure area.
•At least every three months, attach a gauge and
manually check the pressure in the refrigerant circuit.
If the refrigerant pressure is below 71 psigat 70 F (or 46
psig at 50 F), call a qualified service organization and
the appropriateTrane sales office.
Note: Pressure will be approximately 20 psig if shipped
with the optional nitrogen charge.
Installation requirements and
