6 Notes on good practice
6.1 Loading correctly
Before loading the vehicle, the goods must be chilled
and the cooling compartment brought to the correct
temperature so as not to interrupt the cold chain.
When loading, make sure that the cold air emitted by
the cooling unit can circulate freely. The distance be-
tween the load and the roof should be approx. 30 cm.
The air intake and outlet openings of the cooling unit
must not be obstructed.

Cooling compartment
Open the cooling compartment as little as
possible!
If the cooling compartment is frequently opened, warm,
humid air enters leading to a reduction in the system ca-
pacity.
