Page 31: Pre--Trip Inspection
NSPECTION The pre-trip inspection should be performed before picking up any load. This inspection is essential to anticipate and help minimize the possibility of “over-the-road” problems. These checks take only a few minutes. 1. Place the unit’s main switch in the STOP (0) position. 2. - Page 32 6. Over-all Unit - visually inspect the entire unit for leaks, loose bolts, frayed, loose, broken wires, etc. radiator/condenser coils of the unit should be free of dirt, bugs, cardboard, or any other debris that may obstruct airflow across the coils. The evaporator (located inside the trailer) should be free of debris also, especially stretch-wrap, which is often used during transport to prevent cargo shifting.

Page 33: Product Loading
RODUCT OADING BEFORE LOADING: D Pre-cool the trailer. This will remove much of the heat from the inside of the trailer, and give the product better protection when it is loaded. D If possible, place the unit in a defrost cycle immediately before loading. - Page 34 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 trailer.
