(“FREEZE”). For efficient operation, regulate the temperature according to the types of
food stored.

q STORING FOOD IN THE REFRIGERA TOR

The following simple instructions on storage of food in the refrigerator will enable you to
enjoy the fullest and best use of your NORCOLD.
T o prevent the drying out and transfer of odors from one food to another , foods should
always be stored in covered dishes, plastic bags, or wrapped in foil or wax paper.
