Warnings and Cautions
Warnings and cautions are provided in appropriate places throughout this document:
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 and 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.
NOTICE: Warnings and Cautions appear at appropriate sections through-
out this literature. Read these carefully.
�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, may result in minor or moderate injury. It may also be used to
alert against unsafe practices.
CAUTION: Indicates a situation that may result in equipment or property-
damage only accidents.

This is a new manual.
About this manual
This manual describes proper installation
of Model CVGF, 50 Hz and 60 Hz chillers
with the AdaptiView Controls platform.
See Figures 2 and 3 for an illustration of
a CVGF Centrifugal Chiller with the Adap-
tiView Unit Control Panel. These chillers
are equipped with microcomputer-based
control systems. A careful review of this
information along with the submittal
package provided for the unit will assure
that the chiller is correctly installed.
Operation and maintenance information
for models CVGF are covered in this man-
ual.This includes both 50 and 60 Hz. CVGF
centrifugal chillers equipped with theTrac-
er AdaptiVew Chiller Controller system.
A typical product description block is
shown in the Manual.
Carefully review this information and fol-
low the instructions given to successfully
install operate and maintain a CVGF unit.
If mechanical problems do occur, contact
a qualified service organization to ensure
proper diagnosis and repair of the unit.
Unit Nameplate
When the unit arrives, compare all name-
plate data with order, submittal and ship-
ping information. A typical unit nameplate
is shown in Figure 1.
The unit nameplate is located on the left
side of the unit control panel.
Note: Trane starters are identified by a
separate model number found on the
starter.

Loose Parts Inventory
The loose parts items ship in the motor junction box for units without a unit-mount-
ed starter, or in the starter panel for units equipped with a unit-mounted starter. This
includes the isolation pads, extra oil filter, and any optional optional factory-shipped items.

General Information

Unit Description
The CVGF units are singlecompressor, gear-type, watercooled liquid chillers designed
for installation indoors. Each unit is a completely assembled, hermetic package that is
factorypiped, wired, leak-tested, dehydrated, oil-charged, and tested for proper control
operation before shipment.
Note: high-voltage starters are not unit-mounted before shipment.
Figure 2 and Figure 3 show a typical CVGF unit and its components. Water inlet and
outlet openings are covered before shipment. The oil tank is factory-charged with 15
gallons (56.8L) ofTrane Oil 37 and a holding charge of 5 psig (34 kPa) of dry nitrogen at
70°F (21°C).

It is strongly recommended that the piping contractor provide at least 3 feet (914 mm)
of clearance between the preinstallation piping and the planned location of the unit.
This will allow for the proper fit upon arrival of the unit at the installation site. All nec-
essary piping adjustments can be made at that time.
