SAFETY SUMMARY

GENERAL SAFETY NOTICES

The following general safety notices supplement the specific warnings and cautions appearing elsewhere in this

manual. They are recommended precautions that must be understood and applied during operation and maintenance

of the equipment covered herein. The general safety notices are presented in the following three sections labeled:

First Aid, Operating Precautions and Maintenance Precautions. A listing of the specific warnings and cautions

appearing elsewhere in the manual follows the general safety notices.

SAFETY PRECAUTIONS

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. Stay clear of all moving parts when the unit is in

operation and when the unit RUN/STOP Switch (RSS) is in the START/RUN position.

FIRST AID

An injury, no matter how slight, should never go unattended. Always obtain first aid or medical attention immediately.

OPERATING PRECAUTIONS

Always wear safety glasses. Wear hearing protection as required.

Keep hands, clothing and tools clear of the evaporator and condenser fans.

No work should be performed on the unit until all circuit breakers and the RUN/STOP Switch are turned off, and battery

power supply is disconnected.

Always work in pairs. Never work on the equipment alone.

In case of severe vibration or unusual noise, stop the unit and investigate.

MAINTENANCE PRECAUTIONS

Beware of unannounced starting of the unit. This unit is equipped with Auto--Start in both the road and standby modes.

The unit may start at any time. When performing any check of the system make certain the Emergency Switch is in the

OFF position.

Be sure power is turned off before working on motors, controllers, solenoid valves and electrical control switches. Tag

circuit breaker and vehicle ignition to prevent accidental energizing of circuit.

Do not bypass any electrical safety devices, e.g. bridging an overload, or using any sort of jumper wires. Problems with

the system should be diagnosed, and any necessary repairs performed, by qualified service personnel.

When performing any arc welding on the unit or container, disconnect all wire harness connectors from the

microprocessor. Do not remove wire harness from the modules unless you are grounded to the unit frame with a static

safe wrist strap.

In case of electrical fire, open circuit switch and extinguish with CO

(never use water).

AUTO-START

Your refrigeration unit is equipped with Auto-Start in both Start/Stop and Continuous Run modes. The unit may start at

any time. A buzzer will sound for 5 seconds before the unit is started. When performing any check of the refrigeration

unit (e.g., checking the belts, checking the oil), make certain that the RUN/STOP Switch is in the OFF (0) position.

ENGINE COOLANT

The engine is equipped with a pressurized cooling system. Under normal operating conditions, the coolant in the

engine and radiator is under high pressure and is very hot. Contact with hot coolant can cause severe burns. Do not

remove the cap from a hot radiator; if the cap must be removed, do so very slowly in order to release the pressure

without spray.

REFRIGERANTS

The refrigerant contained in 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 you contact your nearest Carrier Transicold authorized repair facility whenever your unit requires

refrigeration system service .
