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

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.
CAU TION
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

the following figure and contains the following
information:
• Unit model and size descriptor
• Unit electrical requirements
• Correct operating charge and refrigerant type
• Unit test pressures and maximum operating
pressures
• Unit literature
SSeerriiaall NNuummbbeerr The unit serial number provides the

Pre-Installation
ASHRAE Standard 15
Compliance
Trane recommends that indoor CenTraVac™chiller
installations fully meet or exceed the guidelines of the
current version of ASHRAE®Standard 15, in addition
to any applicable national, state, or local requirements
This typically includes:
• A refrigerant monitor or detector that is capable of
monitoring and alarming within the acceptable
exposure level of the refrigerant, and that can
actuate mechanical ventilation
• Audible and visual alarms, activated by the
refrigerant monitor, inside the equipment room and
outside of every entrance
• The equipment room should be properly vented to
the outdoors, using mechanical ventilation that can
be activated by the refrigerant monitor
• The purge discharge and the rupture disk must be
properly piped to the outdoors
• If required by local or other codes, a self-contained
breathing apparatus should be available in close
proximity to the equipment room
Refer to the latest copy of ASHRAE Standard 15 for
specific guidelines Trane assumes no responsibility for
any economic, health, or environmental issues that
may result from an equipment room’s design or
function
Unit Shipment
Inspect unit while it is still on the truck for any shipping
damage The chiller ships shrink-wrapped in a 0 010-in
(0 254 mm) recyclable film protective covering Do NOT
remove shrink-wrap for inspection! Inspect for damage
to the shrink-wrap and determine if physical damage
has occurred
Each chiller ships from the factory as a hermetically
assembled package; it is factory-assembled, -wired,
and -tested All openings except for the waterbox vent
and drain holes are covered or plugged to prevent
contamination during shipment and handling “Unit
Components,” p 14 shows an illustration of a typical
unit and its components As soon as the unit arrives at
the job site, inspect it thoroughly for damage and
material shortages In addition:
1 Verify the hermetic integrity of the unit by checking
the chiller pressure for an indication of holding
charge pressure
2 To prevent damaging moisture from entering the
unit and causing corrosion, each chiller is
pressurized with 3 to 5 psig (20 7 to 34 5 kPaG) of
dry nitrogen before shipment
NNoottee:: The holding charge should register
approximately 5 psig (34.5 kPaG) at 72°F (22.2°C).
Place a gauge on the access valve provided
(indicated by arrow and circle in the following
figure) on the refrigerant pump discharge line to
verify the holding charge. If the charge has
escaped, contact your local Trane sales office for
instructions.
3 The loose parts box and isolator pads ship on top of
the control panel box
4 Check the oil sump sight glasses to verify that the
sump was factory-charged with 9 gallons (34 1 L) of
oil If no oil level is visible, contact your local Trane
sales office
IImmppoorrttaanntt:: If isolation springs are installed, do NOT
block oil tank serviceability.

Unit Clearances and Weights
Recommended Unit Clearances
Adequate clearances around and above the chiller are
required to allow sufficient access for service and
maintenance operations Specific unit clearance
requirements are indicated in the submittal package
provided for your unit
• Do NOT install piping or conduit above the
compressor motor assembly or behind the suction
elbow of the unit
• Minimum vertical clearance above the unit is 3 ft
(92 cm)
• Use a housekeeping pad to provide better service
clearances; refer to submittal for more information
Per National Electric Code (NEC) Article 110: Unit
mounted starters from 0 to 600V require a 42 inch
(107 cm) clearance, 601 to 2500V require a 48 inch
(122 cm) clearance, and 2501 to 9000V require a 60 inch
(152 cm) clearance Refer to NEC and local electrical
codes for starter and control panel clearance

IImmppoorrttaanntt:: The weight information provided here
should be used for general information
only. Trane does not recommend using this

Weights (kg)
IImmppoorrttaanntt:: The weight information provided here
should be used for general information
only. Trane does not recommend using this
weight information for considerations
relative to chiller handling, rigging, or
placement. The large number of variances
between chiller selections drives variances
in chiller weights that are not recognized in
these tables. For specific weights for your
chiller, refer to your submittal package.
