Energy Saving Tips

Keep door closed as much as possible. Ensure seals are clean and tight. Position away from heat sources. Set temperature to -18°C unless specific needs require lower. Defrost manually only if ice buildup occurs (unlikely with NoFrost).

Care & Cleaning

Unplug before cleaning interior if performing deep clean (not required for routine NoFrost operation).

Exterior: Wipe with damp cloth and mild detergent; dry thoroughly.
Interior: Remove shelves and baskets; wash with warm soapy water. Rinse and dry.
Door seals: Clean gently to maintain elasticity.
