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.

General

Information

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.)
