Introduction
This guide has been prepared for the operator of Carrier Transicold
35X with Standby, and 40X and 50X Truck Refrigeration units with
Cab Command, Two 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. Pleasetake thetime toread the
information contained in this booklet and refer to it whenever you
have a question about the operation of your Carrier Transicold
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 reli-
ability.
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 cycling 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.
Emergency Switch (40/50X units only)
The unit can be completely
shut down manually by the
emergency switch inside the
frame of the condenser unit.
The emergency switch must
be in the on position to allow
the unit to restart with the
“ON” key of the cab
command.

Unit Identification
The unit is identified by a nameplate attached to the frame of the
unit. This nameplate identifies the complete model number of the
unit, the serial number, the type of refrigerant and charge, 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 they may
properly assist you. 40/50X Nameplate

Operating Principle
After startingup the refrigeration unitbypressingthe ONkey onthe
Cab Command Two Controller, unit start -up and shutdown are
automatic.
•On Road operation: An open-type compressor is driven
by the vehicle’s engine. The vehicle battery powers the
evaporator and condenser fans. The unit automatically
shuts down when the engine is switched off with the
ignition key.
•On Standby operation: A standby compressor is
energized, and a transformer is used to power the
evaporator and condenser fans. The power connection
is detected by the controller, which automatically starts
up in the unit in Standby mode.
•If the ignition key is switched on while the unit is
connected to power or the unit is connected to standby
power while the engine is operating, the controller
triggers a visual alarm in the form of a flashing red
malfunction light and readout.
•In all cases, the unit can be completely shut down
manually by pressing the OFF key on the Cab
Command Two Controller.
