Loading Procedure

Important Product should be pre-cooled before loading. Thermo King units are designed to maintain the load at the temperature at which it is loaded. Transport refrigeration units are not designed to reduce the load temperature.
Note To minimize frost accumulation in the evaporator coil and a heat increase inside the load compartment, ensure that the unit is OFF before opening the doors.

  1. Carefully check and record the load temperature when loading the refrigerated cargo. Note whether any products are out of temperature range.

  2. Load the product to verify sufficient air space is maintained around and through the load in compartment. Airflow around the cargo must not be restricted. DO NOT block the evaporator inlet or outlet. Refer to the Air Circulation Diagram on the following page.

  3. Minimize door opening times and close door(s) in between loading to preserve box temperature.

Air Circulation Diagram

1. Evaporator air outlet not blocked by cargo.
2. Sufficient air space is maintained above cargo.
3. Good air circulation around and between cargo.
4. Cargo separated from bulkhead and walls a minimum of 4.00 inch (100 mm).
5. Evaporator air inlet not blocked by cargo.
