Page 19: Product Loading
Product Loading Before Loading • Pre-cool the body. This will remove much of the heat from the inside of the body and give the product better protection when it is loaded. • Place the unit in a defrost cycle immediately before loading. This will remove moisture accumulated on the evaporator coil. - Page 20 All products should be kept away from the side°walls of the body, to allow air 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.
