62--61177--01
CAUTION
Under no circumstances should anyone attempt to repair the Logic or Display
Boards. Should a problem develop with these component, contact your nearest
Carrier Transicold dealer for replacement.
Under no circumstances should a technician electrically probe the processor at any point, other
than the connector terminals where the harness attaches. Microprocessor components operate at
different voltage levels and at extremely low current levels. Improper use of voltmeters, jumper
wires, continuity testers, etc. could permanently damage the processor.
Most electronic components are susceptible to damage caused by electrical static discharge
(ESD). In certain cases, the human body can have enough static electricity to cause resultant
damage to the components by touch. This is especially true of the integrated circuits found on the
truck/trailer microprocessor.
3.1. Warning stickers maintenance
a. Keep the warning pictograms clean and without any obstruction material.
b. Clean the pictograms with water and soap and wipe them with soft fabric.
c. Replace damaged or missing pictograms with new pictograms available in Carrier network.
d. If a component having a pictogram is replaced by a new one, be sure that the new component has the
right pictogram.
e. Place a warning pictogram by applying it on a dry surface. Press to external sides to eliminate air bubbles.
4. PRODUCT LOADING
Proper air circulation in the insulated box, air that can move around and through the load, is a critical element
in maintaining product quality during transport. If air cannot circulate completely around the load, hot spots or
top--freeze can occur.
The use of pallets is highly recommended. Pallets, when loaded so air can flow freely through the pallets to
return to the evaporator, help protect the product from heat passing through the floor of the truck. When using
pallets, it is important to refrain from stacking extra boxes on the floor at the rear of the truck, because this will
cut off the airflow.
Product stacking is another important factor in protecting the product. Products that generate heat, fruits and
vegetables for example, should be stacked so the air can flow through the product to remove the heat; this
is called “air stacking” the product. Products that do not create heat, meats and frozen products, should be
stacked tightly in the center of the box. All products should be kept away from the sidewalls of the body, allo-
wing air to flow between the body and the load; this prevents heat filtering through the walls from affecting the
product.
It is important to check the temperature of the product being loaded to ensure that it is at the correct
temperature for transport. The refrigeration unit is designed to maintain the temperature of the product at the
temperature at which it was loaded; it was not designed to cool a warm product.

10 62--61177--01
SOME ADVICE
Before loading
DPre--cool the inside of the insulated body by lowering the temperature for about 15 minutes.
DEvacuate the humidity existing inside the box by carrying out a manual defrost. This can only take place
when enabled by the defrost thermostat (box temperature lower than 3_C.
DEvaporator fans are protected by safety grills. In the event of heavy duty use of the unit, ice can accumulate
on the grills. It is therefore recommended to clean them regularly by means of a small brush. The operation
MUST be done when the unit has been SHUT DOWN.
When loading
DTo be carried out with the unit stopped.
DIt is recommended to open doors as little as possible to avoid the intake of hot air and humidity.
DSelect the temperature by means of the thermostat, according to the transported goods.
DCheck the internal temperature of the goods being loaded (using a probe thermometer).
Load spacers
Load on pallets
DTake care not to obstruct the air intakes on
the evaporator section and the ventilation
ducts.
DLeave a free space of about :
- 6 to 8 cm between load and frontwall,
- 20 cm between the top of the load and the
roof,
- between the floor and the load (gratings,
pallets).
DDo not forget to close the doors.
DBefore closing the doors, check your load once more and see that nobody is shut inside the box.
NOTE :
For stationnary utilization, we recommend
to place the body in the shade.
IMPORTANT
Never leave your unit more than a month
without running.

6. QUICK GLANCE ON THE DISPLAY BOARD
Keep the fold out sheet while reading the instructions.
6.1. Cab control
Keep the fold out sheet while reading the instructions.
This functionnal accessory simplifies all control operations. From his seat, the driver can carry out all the
control operations : shut--down, automatic start--up in road mode, adjusting the setpoint, defrost.
The driver can display the box temperature and see whether the setpoint is being maintained by checking the
green indicator. The indicator lights up red in the event of a malfunction. When the battery voltage is too low,
a fail--safe system shuts down the unit. Unit restart is automatic and time--delayed if the voltage rises to the
normal level.

Road compressor oil type : The road compressors are supplied with CARRIER POLYOLESTER (POE) oil.
The presence of a sticker indicates that oil--change has been correctly carried out in our Carrier Transicold
plant. Oils of PAG type are strictly incompatible with the operation of our units : never use an oil other than
that approved by Carrier.
Oil analysis : on request, we can analyze your compressor oil.
To do this, we send a small drum with a label on which you should indicate : the type of compressor, the lapse
time or mileage since the last oil change, the type of Carrier equipment, the date of initial operation
