This guide has been prepared for the operator of Carrier Transport

Air Conditioning systems. It contains basic instructions for the daily

operation of the air conditioning system as well as safety

information, and other information that will help you to maintain a

comfort level for your self and your passengers. Please take the

time to read the information contained in this booklet and refer to

it whenever you have a question about the operation of your Carrier

Transport Air Conditioning system.

More comprehensive information can be found in the Split System

Operation and Service Manual (T--299). This manual can be

obtained from your Carrier Transport A/C dealer.

Your air conditioning system has been engineered to provide long,

trouble-free performance when it is properly operated and

maintained. A comprehensive maintenance program will help to

insure that the unit continues to operate reliably. Such a

maintenance program will also help to control operating costs,

increase the unit’s working life, and improve performance.

Some Vehicles may require information from manuals supplied by

the vehicle manufacturer or other special equipment suppliers. We

urge you to review all these publications carefully. This will help you

enjoy safe and trouble--free operation of your vehicle.

When having your unit serviced, be sure to specify genuine Carrier

Transicold replacement parts for the highest quality and best

reliability.
