The freezer needs air.
The side walls become warm whilst the appliance is on. The heat is
generated by the special refrigerating system (shell condenser) and helps
prevent condensation. In order for the heat to be able to be dissipated, air
must be able to circulate around all the side walls.
Attention! To function correctly the appliance requires good ventilation.
Make sure that the side walls and the base of the appliance are not covered
or obstructed.
