This guide has been prepared for the operator of Carrier

Transicold diesel truck refrigeration units. It contains basic instructions for the daily operation of the refrigeration unit as well as safety information, troubleshooting tips, and other information that will help you to deliver the load in the best possible condition.

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 Transicold Integra 30s unit.

Your refrigeration unit has been engineered to provide long, trouble-free performance when it is properly operated and maintained. The checks outlined in this guide will help to minimize over-the-road problems. In addition, 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.

This guide is intended as an introduction to your unit and to provide general assistance when needed. More comprehensive information can be found in the Operation and Service Manual for your unit. This manual can be obtained from your Carrier

Transicold dealer.

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

Transicold replacement parts for the highest quality and best reliability.

At Carrier Transicold, we are continually working to improve the products that we build for our customers. As a result, specifications may change without notice.

AFETY

Your Carrier Transicold refrigeration unit has been designed with the safety of the operator in mind. During normal operation, all moving parts are fully enclosed to help prevent injury. During all pre-trip inspections, daily inspections, and problem troubleshooting, you may be exposed to moving parts; please stay clear of all moving parts when the unit is in operation.

R

EFRIGERANTS

The refrigerant contained in the refrigeration system of your unit can cause frostbite, severe burns, or blindness when in direct contact with the skin or eyes. For this reason, and because of legislation regarding the handling of refrigerants during system service, we recommend that, whenever your unit requires service of the refrigeration system, you contact your nearest Carrier

Transicold authorized repair facility for service.

BEFORE LOADING:

D

Pre-cool the body. This will remove much of the heat from the inside of the body, and give the product better protection when it is loaded.

D

Place the unit in a defrost cycle immediately before loading.

This will remove moisture accumulated on the evaporator coil.

DURING LOADING:

D

Turn the unit off!

D

Check product temperature during loading.

D

Ensure that the air return and supply opening remain unobstructed.

D

Leave approximately 4 to 5 inches between the load and the front wall for air return to the unit.

D

Leave at least 10 to 12 inches between the top of the load and the ceiling to ensure that there is nothing to prevent airflow to the rear of the body

D

Load product on pallets to provide free air return to unit and improve product protection.

Proper air circulation in the truck body, air that can move around and through the load, is a critical element in maintaining product quality during transport. If air cannot circulate completely around the load, hot spots or top-freeze can occur.

The use of pallets is highly recommended. Pallets, when loaded so air can flow freely through the pallets to return to the evaporator, help protect the product from heat passing through the floor of the truck. When using pallets, it is important to refrain from stacking extra boxes on the floor at the rear of the truck, this will cut off the airflow.

Product stacking is another important factor in protecting the product. Products that generate heat --- fruits and vegetables, for example --- should be stacked so the air can flow through the product to remove the heat; this is called “air stacking” the product. Products that do not create heat --- meats and frozen products --- should be stacked tightly in the center of the trailer.

11

All products should be kept away from the side-walls of the body, to allow air flow between the body and the load; this prevents heat filtering through the walls from affecting the product.

It is important to check the temperature of the product being loaded to ensure that it is at the correct temperature for transport.

The refrigeration unit is designed to maintain the temperature of the product at the temperature at which it was loaded; it was not designed to cool warm product.

When multiple units are in use, each unit must be operated on its own electrical circuit. You should never operate more than one unit on a circuit breaker.

I mportant note: This information is provided as a guideline only.

When preparing a circuit for operation of the refrigeration unit, a licensed electrician should be contracted. A licensed electrician is familiar with all local ordinances and special requirements for your area and can ensure that the circuits are properly designed, installed, and connections are correct.
