    SAFETY SAFETY PRECAUTIONS Your Carrier Transicold 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 pretrip 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 and when the unit main power switch is in the START/RUN position.
  • Page 7 SPECIFIC WARNING AND CAUTION STATEMENTS (Continued) WARNING When removing the radiator cap, wait at least ten minutes after the engine has stopped and cooled down. Otherwise, hot water may discharge from the radiator, scalding anyone nearby. WARNING Check the injection nozzle only after confirming that nobody is near the spray. If the spray from the nozzle contacts the human body, cells may be destroyed and blood poisoning may result.
