SAFETY

Your Carrier Transicold refrigeration unit has been designed with

the safety of the operator in mind. During all pre-trip inspections,

daily inspections, and problem troubleshooting, you may be

exposedtomovingparts;pleasestayclearofallmovingpartswhen

the unit is in operation and when the Start/Run-Off Switch is in the

START/RUN position.

AUTO-START

YourrefrigerationunitisequippedwithAuto-StartinbothStart/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 Start/Run-Off Switch

is in the OFF position.

ENGINE COOLANT

The engine is equipped with a pressurized cooling system. Under

normal operating conditions, the coolant in the engine andradiator

isunder highpressureandisvery hot. Contact withhot coolantcan

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 the refrigeration system of 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, 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 battery. A battery explosion can cause

serious physical harm and/or blindness.

62--10601

UNIT IDENTIFICATION

Each unit is identified by a decal attached to the frame of the unit.

This decal is on the roadside vertical frame post behind the

roadside side door. This decal identifies the complete model

number of the unit, the serial number, the refrigerant charge and

quantity, and the date the unit was placed in service.

If a problem occurs, please refer to the information on this decal,

and make a note of the model and serial number before calling for

assistance. This information will be needed when you contact a

technician or Carrier Transicold Service Engineer so that they may

properly assist you.

DISPLAY

SELF TEST

562--10601

The microprocessor controller will run a self test. All of the mode

lights will light, all of the segments on the display will be turned on.

The display will then show the setpoint temperature on the left and

the box temperature of the trailer on the right. The last character

(after the degree symbol) shows the temperature units as F

(Fahrenheit) or C (Celsius).

If the unit is in Auto Start/Stop mode or Continuous Run/Auto

Operation mode, the glow plugs will energize, the buzzer will

sound, and the diesel engine will start.

If the unit is set for Continuous Run/Manual Operation mode, the

unit must be started manually.

WARNING

Under no circumstances should ether or any other

starting aids be used to start engine.

The microprocessor controller monitors box temperature, battery

voltage, and engine coolant temperature. Once the setpoint is

reached the controller will shut off the diesel engine to conserve

fuel. The controller will not shut off the engine if the battery voltage

is not sufficient to restart it.

The controller will restart the engine if any of the following criteria

have been met:

SBox temperature has changed by ¦11°F(¦6.1°C)for setpoints

in the perishable range and +11°F(+6.1°C) for setpoints in the

frozen range DURING minimum off time.

SBox temperature has moved away from setpoint by ¦3.6°F

(2.0°C) AFTER minimum off time for setpoints in the perishable

range or +3.6°F(2.0°C) for setpoints in the frozen range.

SThe battery voltage drops below 11 Vdc (12.2 Vdc for units with

EEPROM Rev 3.25 and higher -- Refer to Page 21 for unit data).

SThe engine coolant temperature drops below 34°F(1°C).
