It is normal for frost to build up on the Super-Freezer. This comes
from moisture in the air that enters the food compartment when the
door is opened. When this moisture strikes the cold surface of the
Super-Freezer, it turns to frost. Removing the frost periodically keeps
operating costs low.
=When to remove frost=--The speed with which frost builds up depends
upon the amount of moisture in the air and how many times you open the
refrigerator door. When the frost builds up to about ¹⁄₄ inch, or the
_thickness_ of a pencil, it should be removed by one of the methods
below.
