IMPORTANT: Do not turn on SuperFrost:

• When placing already frozen food in the freezer.
• When freezing up to approximately 4-1/2 lbs (2 kg) fresh food daily.

Ice Maker

Freezing and Storage

• Pack frozen food in standard freezer bags or reusable containers (plastic, metal, aluminum).
• Do not allow fresh food to contact already frozen food.
• Keep packages dry to prevent them from sticking together.
• Write the date and contents on packages and do not exceed stated storage times to prevent spoilage.
• Pack food in quantities suitable for your household. For quick freezing, do not exceed:
• Fruit, vegetables: up to 2-1/4 lbs (1 kg)
• Meat: up to 5-1/2 lbs (2.5 kg)
• Do not freeze bottles and cans with carbonated drinks, as they may burst. Cool drinks quickly, but remove bottles from the freezer after one hour.
• Thaw only the amount of food needed. Cook thawed food as quickly as possible. Thawing methods:
• Microwave oven.
• Refrigerator (safer, less chance of bacteria growth; recommended for dense foods like roasts or poultry).

Safety Instructions and Warnings for the Automatic Ice Maker

• The ice maker is designed exclusively for making ice cubes needed by a household.
• All repairs must be done by customer service personnel or trained technicians.
• Do not consume or use the first three batches of ice, especially when first using the appliance or after a long period of non-use.
• The manufacturer is not liable for damage caused by equipment or water lines between the solenoid valve and the water supply.
• The ice maker operates only when the refrigerator-freezer is connected to the electrical outlet and the freezer compartment is operating.
• The ice maker only makes ice cubes if the drawer is completely closed.

Making Ice Cubes

The ice maker is located in the top left drawer of the freezer compartment, labeled "IceMaker".
