1.2 SAFETY PRECAUTIONS
Your Carrier Transicold refrigeration unit has been
designed with the safety of the operator in mind. Dur-
ing normal operation, all moving parts are fully en-
closed to help prevent injury. During all pre-trip inspec-
tions, 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 Start/Run-Off switch is in the
START/RUN position.
Under no circumstances should anyone at-
tempt to repair the Logic or Display
Boards. Should a problem develop with
these components, contact your nearest
Carrier Transicold dealer for replacement.
Under no circumstances should a techni-
cian electrically probe the processor at any
point, other than the connector terminals
where the harness attaches. Microproces-
sor components operate at different volt-
age levels and at extremely low current
levels. Improper use of voltmeters, jumper
wires, continuity testers, etc. could perma-
nently damage the processor.
Most electronic components are suscepti-
ble to damage caused by electrical static
discharge (ESD). In certain cases, the hu-
man body can have enough static electrici-
ty to cause resultant damage to the com-
ponents by touch. This is especially true of
the integrated circuits found on the
truck/trailer microprocessor.
Auto-Start
Your refrigeration unit is equipped with Auto-Start in
both Start-Stop and Continuous Run Operation. The
unit may start at any time when the Start/Run-Off
Switch (SROS) is in the Start/Run position. 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 cer-
tain that the SROS is in the OFF position.
Engine Coolant
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 radiator or bottle. If the
cap must be removed, cover it with a rag and remove
it very slowly in order to release the pressure without
spray.
Refrigerant
The refrigerant contained in the refrigeration system of
your unit can cause frostbite, severe burns, or blind-
ness 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.
Battery
This unit is equipped with a lead-acid type battery. The
battery normally vents small amounts of flammable
hydrogen gas. Do not smoke when checking the bat-
tery. A battery explosion can cause serious physical
harm and/or blindness.
1.3 SPECIFIC WARNING AND CAUTION
STATEMENTS
To help identify the label hazards on the unit and ex-
plain the level of awareness each one carries, an ex-
planation is given with the appropriate consequences:
DANGER - warns against an immediate hazard which
WILL result in severe personal injury or death.
WARNING - warns against hazards or unsafe condi-
tions which COULD result in severe personal injury or
death.
CAUTION - warns against potential hazard or unsafe
practice which could result in minor personal injury, or
product or property damage.
The following statements are specifically applicable to
this refrigeration unit and appear elsewhere in this
manual. These recommended precautions must be
understood and applied during operation and mainte-
nance of the equipment covered herein.
