Load Space Considerations

The load space must be always kept clean and only cleaning agents that will not affect the products should be used.

If an air chute is installed and extends the full length of the box provision should be made to allow for the dividing door to be closed. Therefore, a system is required that facilitates the air chute to open to allow correct air distribution from the chute.

A compartment moveable dividing wall is used in multi-temperatures applications to separate the compartments to allow them to operate at different temperatures. The dividing door must not be positioned any less than 1300 mm from the air outlet of the remote ZONE 2 S3A evaporator and any less than 2500 mm from the air outlet of the host ZONE 1 evaporator.

If a small load is carried at one temperature, ZONE 1 should be utilised, and the dividing wall should be used to reduce the compartment size. The dividing wall must not be positioned any less than 2500 mm from the air outlet of the host ZONE 1 evaporator. This will provide better air/temperature management and help reduce fuel consumption.

A minimum of 100 mm clearance must be provided between the top of the load and the air intake of a remote ZONE 2 S3A evaporator.

An air gap of minimum 50 mm should be always maintained between the load and the walls.

If the dividing wall is positioned tightly against the load, satisfactory air circulation and temperature management will not be achieved.

If the load is positioned tightly against the body internal walls, satisfactory air circulation and temperature management will not be achieved.

If the unit is to be used as a single temperature mode, the dividing door should be stowed in such a way that it does not interrupt the airflow from the main host ZONE 1 unit evaporator. The recommended position of the stowed bulkhead is shown below; this will aid airflow when operating in single temperature mode.
