Warning Stickers Maintenance; Product Loading - Carrier XARIOS X150-04 Operator's Manual

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.

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.

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.
