How adding a large amount of food can effect temperature
Adding a large amount of food warms the freezer. It can take several hours for the freezer temperature to stabilize after adding large quantities of unfrozen food.
Before the first use, allow the freezer to cool 6 to 8 hours before filling with frozen food. Let the freezer cool overnight before adding large amounts of unfrozen food. Do not add more than 2 to 3 pounds (0.907 to 1.360 kg) of unfrozen food per cubic foot of freezer space.
