General information

Safety recommendations

To avoid death, injury, equipment

or property damage, the following

recommendations should be

observed during maintenance and

service visits:

1. The maximum allowable

pressures for system leak testing on

low and high pressure side are given

in the chapter “Installation”. Always

provide a pressure regulator.

2. Disconnect the main power

supply before any servicing on the

unit.

3. Service work on the refrigeration

system and the electrical system

should be carried out only by

qualified and experienced personnel.

Reception

On arrival, inspect the unit before

signing the delivery note. Specify

any visible damage on the delivery

note, and send a registered letter

of protest to the last carrier of the

goods within 7 days of delivery.

Notify the local TRANE sales office

at the same time. The delivery

note must be clearly signed and

countersigned by the driver.

Any concealed damage shall be

notified by a registered letter of

protest to the last carrier of the

goods within 7 days of delivery.

Notify the local TRANE sales office

at the same time.

Important notice: No shipping claims

will be accepted by TRANE if the

above mentioned procedure is not

respected.

For more information, refer to the

general sales conditions of your local

TRANE sales office.

Note: Unit inspection in France.

Delay to send registered letter

in case of visible and concealed

damage is only 72 hours.

Foreword

These instructions are given as

a guide to good practice in the

installation, start-up, operation,

and maintenance by the user,

of Trane CGWN/CCUN chillers.

They do not contain full service

procedures necessary for the

continued successful operation

of this equipment. The services

of a qualified technician should

be employed through the medium

of a maintenance contract with a

reputable service company. Read

this manual thoroughly before unit

start-up.

Units are assembled, pressure

tested, dehydrated, charged and run

tested before shipment.

Warnings and cautions

Warnings and Cautions appear at

appropriate sections throughout

this manual. Your personal safety

and the proper operation of this

machine require that you follow

them carefully. The constructor

assumes no liability for installations

or servicing performed by unqualified

personnel.

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 or

for equipment or property-damage-

only accidents.

General information

Warranty

Warranty is based on the general

terms and conditions of the

manufacturer. The warranty is

void if the equipment is repaired

or modified without the written

approval of the manufacturer, if the

operating limits are exceeded or if

the control system or the electrical

wiring is modified. Damage due

to misuse, lack of maintenance

or failure to comply with the

manufacturer’s instructions or

recommendations is not covered by

the warranty obligation. If the user

does not conform to the rules of this

manual, it may entail cancellation

of warranty and liabilities by the

manufacturer.

Maintenance contract

It is strongly recommended that

you sign a maintenance contract

with your local Service Agency.

This contract provides regular

maintenance of your installation

by a specialist in our equipment.

Regular maintenance ensures

that any malfunction is detected

and corrected in good time and

minimizes the possibility that serious

damage will occur. Finally, regular

maintenance ensures the maximum

operating life of your equipment.

We would remind you that failure

to respect these installation and

maintenance instructions may result

in immediate cancellation of the

warranty.

Training

To assist you in obtaining the best

use of it and maintaining it in perfect

operating condition over a long

period of time, the manufacturer

has at your disposal a refrigeration

and air conditioning service school.

The principal aim of this is to give

operators and technicians a better

knowledge of the equipment they

are using, or that is under their

charge. Emphasis is particularly

given to the importance of periodic

checks on the unit operating

parameters as well as on preventive

maintenance, which reduces the

cost of owning the unit by avoiding

serious and costly breakdown.
