Energy Saving Tips

Maximize efficiency and reduce electricity consumption.

Set optimal temperature: Maintain -18°C (0°F); each degree lower increases energy use by ~5%.
Use Energy Saving mode: Activate during periods of low usage or when away.
Minimize door openings: Plan retrieval to reduce cold air loss.
Ensure proper sealing: Check door gaskets regularly; replace if damaged.
Defrost manually only if needed: NoFrost system typically prevents ice, but check vents periodically.
Keep condenser coils clean: Vacuum rear grille every 6 months for optimal heat exchange.

WARNING! Do not place hot food directly into freezer; allow to cool first to reduce energy load.

Care & Cleaning

Unplug before cleaning. Use mild detergent and soft cloth; never use abrasive cleaners or solvents.

Interior: Remove all food. Wipe shelves, drawers, and walls with solution of warm water and baking soda.
Exterior: Clean door and control panel with damp cloth; dry thoroughly.
Door gaskets: Wipe with clean water to maintain seal; check for cracks.
Condenser coils: Vacuum rear grille gently to remove dust buildup.
Defrosting: NoFrost system eliminates need for manual defrosting. If ice appears, check door seal or contact service.

CAUTION! Never use steam cleaners, sharp objects, or chemical cleaners. Do not pour water into interior or over control panel.
