Introduction
This guide has been prepared for the operator of Carrier
Transicold 20X and 35X Road Only Truck Refrigeration units with
Cab Command Controller. It contains basic instructions for the
daily operation of the refrigeration unit as well as safety
information, 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
truck refrigeration unit.
Your refrigeration unit 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.
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.

Safety
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.
WARNING
Beware of unannounced starting of the fans
caused by the thermostat and the start/stop cyc-
ling of the unit.
Refrigerants
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.
WARNING
Inspect battery cables for signs of wear,
abrasion or damage at every pretrip inspection
and replace if necessary. Also check battery
cable routing to ensure that clamps are secure
and that cables are not pinched or chafing
against any components.

The unit is identified by a nameplate which identifies the complete
model number of the unit, the serial number, the refrigerant charge
and quantity, and the date the unit was placed in service.
If a problem occurs, please refer to the information on this plate,
and make a note of the model and serial number before calling for
assistance. This information will be needed when you contact a
technician or Carrier Transicold Service Engineer so that he or she
may properly assist you.
