OPERATOR’S MANUAL FOR
XSERIES DIRECT DRIVE TRUCK UNITS
WITH CAB COMMAND CONTROLLER
This guide has been prepared for the operator of Carrier Transicold
X Series direct drive truck refrigeration units using the 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 unit. The unit
may cycle the fans and operating compressor unex-
pectedly as control requirements dictate. Press OFF
key on the Cab Command.
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.

UNIT IDENTIFICATION
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.

After starting up the refrigeration unit by pressing the ON key on the
Cab Command, unit start--up and shut--down are automatic.
Road operation, an open--type compressor is driven by the
engine of the vehicle. The vehicle battery powers the
evaporator and condenser fans. The unit automatically shuts
down when the engine is switched off with the ignition key.

PRODUCT LOADING
BEFORE LOADING:
DPre-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.
DPlace the unit in a defrost cycle immediately before loading. This
will remove moisture accumulated on the evaporator coil.
DURING LOADING:
DTurn the unit off!
DCheck product temperature during loading.
DEnsure that the air return and supply opening remain
unobstructed.
DLeave approximately 4 to 5 inches between the load and the
front wall for air return to the unit.
DLeave 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
DLoad 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.

13 62--10892
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.

temperature.
