About this Manual
This manual describes proper
installation of Model CVGF, 50 Hz
and 60 Hz chillers with the Tracer
CH530 Controls platform. See
Figures 2 and 3 for an illustration
of a CVGF Centrifugal Chiller
with the Tracer CH530 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.
Unit Identification -
Nameplates
When the unit arrives, compare
all nameplate data with order,
submittal and shipping
information. A typical unit
nameplate is shown in Figure 1.

CVGF-SVN02B-E4
Unit Nameplates
The CVGF unit nameplate
(Figure 2 shows the nameplate
location) is applied to the
exterior surface of the control
panel. The starter nameplate is
located inside the starter panel.
The unit nameplate provides the
following information:
• Unit model
• Unit serial number
• Unit device number - identifies
unit electrical requirements
- Lists correct operating
charges of HFC-134a and
lubrication oil
- Lists unit test pressures and
maximum working pressures
The starter nameplate provides
the following information:
• Panel model number
• Rated load amps
• Voltage
• Electrical characteristics -
starter type, wiring
• Options included
Unit Inspection
When the unit is delivered, verify
that it is the correct unit and that
it is properly equipped.
Inspect all exterior components
for visible damage. 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 appropriate
Trane Sales Office.
Do not proceed with installation
of a damaged unit without sales
office approval.
Inspection Checklist
To protect against loss due to
damage incurred in transit,
complete the pre-commissioning
checklist, which can be obtained
from your Trane representative.
• 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 10
days after receipt.
• 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 Trane sales
representative and arrange for
repair. Do not repair the unit,
however, until damage is
inspected by the transportation
representative.

General
Information

Loose Parts Inventory
The loose parts items ship in the
motor junction box for units
without a unit-mounted 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 factory-shipped
items.
Unit Description
The CVGF units are single-
compressor, gear-type, water-
cooled liquid chillers designed
for installation indoors. Each unit
is a completely assembled,
hermetic package that is factory-
piped, 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) of Trane Oil 37 and a
holding charge of 5 psig (34 kPa)
of dry nitrogen at 70°F (21°C).
(See the Operation Maintenance
Manual for equivalent oil
specification.)
