Storage Shelves/Storage Racks
Depending on the model, your appliance is equipped with either glass storage shelves or storage racks. A glass storage shelf must always remain inserted into the lower guide track above the fruit and vegetable trays, so that fruits and vegetable remain fresh longer. The remaining storage shelves can be adjusted to various heights: Pull the storage shelf forward and remove. Insert at a different height.
