Monitoring: Display shows actual internal temperature; allow 24 hrs for stabilization after changes.
Seasonal adjustment: In warmer ambient temperatures, you may need a slightly colder setting.

Tip: Avoid frequent door openings and keep door closed as much as possible to maintain temperature.

Storage Organization

Efficient use of space ensures better air circulation and cooling.

Baskets: Use for smaller items, fruits, vegetables, and pre-packaged foods.
Shelves: Ideal for larger items, trays, and bulk storage.
Door compartments: Store frequently used items or smaller packages.
Labeling: Date and label all stored items for first-in, first-out use.
Avoid overloading: Do not block air vents inside the freezer.
Pre-freezing: Spread warm food items out to cool before stacking to freeze faster.

WARNING! Do not store flammable, explosive, or corrosive substances. Keep food sealed to prevent odor transfer and freezer burn.

Energy Saving Tips

Maximize efficiency to reduce electricity costs.

Set temperature to recommended -18°C (0°F); colder settings use more energy.
Ensure door seals are clean and tight. Test by closing a piece of paper; if it pulls out easily, seals may need replacing.
Defrost manually only if NoFrost indicator suggests maintenance (rare).
Place freezer in a cool location, away from ovens, heaters, or direct sun.
Allow hot food to cool to room temperature before freezing.
Keep the freezer reasonably full for better thermal mass, but not overloaded.

Care & Cleaning

Unplug unit before cleaning. Never use sharp tools, hot water, or abrasive cleaners.

Exterior: Wipe with a soft, damp cloth and mild detergent. Dry thoroughly.
Interior: Remove all food. Clean shelves, baskets, and interior surfaces with a solution of baking soda and water (2 tbsp per quart). Rinse with a damp cloth and dry.
Door Seals: Clean gently with water and soft cloth to maintain seal integrity.
Condenser Coils (rear): Vacuum dust from coils annually to maintain efficiency.
Defrosting: NoFrost system eliminates need for manual defrosting under normal use.

CAUTION! Do not use steam cleaners, scouring pads, or chemical solvents. Never pour water into or over the unit.
