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.
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, problem troubleshooting, you may be exposed to moving parts; please stay clear of all moving parts when the unit is in operation.

Unit Operation Operating Principle After starting up the refrigeration unit by pressing the ON key on the Cab Command, unit start-up and shutdown 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.
Starting the Unit 40°F 1. Press the ON key. Start-up may be time- delayed. 2. Check if box temperature is displayed. 3. Check that the road operation light is on. NOTE: If standby power cord is plugged in, the controller will trigger a visual alarm in the form of a flashing alarm light and readout (4), and the unit will run in standby mode.

Product Loading Before Loading • 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. • Place the unit in a defrost cycle immediately before loading. This will remove moisture accumulated on the evaporator coil.

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.
These are included for reference only and should not be considered preemptive of the set point required by the shipper or receiver. More detailed information can be obtained from your Carrier Transicold dealer. Setpoint Range Product °F...
