SAFETY
WARNING
Unit may start automatically at any time even if the switch
is in the OFF position. Use proper lockout/tagout proce-
dures before inspection/servicing. All unit inspection/
servicing by properly trained personnel only.
This 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 any inspection or
servicing with the doors open you may be exposed to moving parts;
please stay clear of all moving parts when the unit is in operation.
NOTE TO TECHNICIANS
Refer to the Operation & Service Manual for a complete list
of safety precautions.
AUTO-START
This refrigeration unit is equipped with Auto-Start in both Start-Stop and
Continuous Operation. 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., visually checking belts, checking
the oil), place unit in Inspect Mode and disconnect the starter solenoid
connector.
COOLING SYSTEM
The engine is equipped with a pressurized cooling system including a
pressurized coolant bottle. 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 coolant system; if cap must be removed, cover it with a
rag and remove very slowly in order to release pressure without spray.
REFRIGERANT
The refrigerant contained in the refrigeration system of this 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) we recommend that you contact your
nearest Carrier Transicold authorized repair facility whenever service
of the refrigerant system is required.
BATTERY
This unit may be equipped with a lead-acid type battery. The battery
normally vents small amounts of flammable hydrogen gas. Do not
smoke when checking the battery. A battery explosion can cause
serious physical harm and/or blindness.

inspections of the unit.
Inspect Mode is a user activated feature that forces the unit to
shutdown and remain in shutdown regardless of operating state.
After unit inspection, Inspect Mode must be manually disabled, at
which point the unit will resume standard operation.
Inspect Mode is not a substitute for proper Lockout/Tagout
procedures, which are always required when servicing the unit.
