Humidity in the air can form frost inside the cooling unit, which also reduces the cooling performance.
Defrost the cooling unit in good time and regularly.
Proceed as follows to defrost the cooling unit:
•
Switch off the cooling box and disconnect the mains plug.
•
Open the lid and remove all items from the cooling unit.
•
If necessary, store the goods in another cooling unit so that they stay cold and do not thaw out.
•
Leave the lid open to defrost the ice more quickly.
•
Never use hard, sharp or pointed tools to remove the layers of ice or to loosen frozen items. Disre-
gard can cause damage to the unit.
•
Remove the drain plug in the base to allow the water condensate to drain out. Dry the interior with a
soft cloth.
•
Close the drain plug.
•
The cooler is now ready for use again.
