WARNING! Do not store explosive substances, flammable sprays, or carbonated drinks in glass bottles in the freezer.

Cleaning & Maintenance

Frost-free operation minimizes maintenance. Regular cleaning is required.

Unplug the appliance before any cleaning.
Interior: Clean shelves, drawers, and interior surfaces with a soft cloth dampened with warm water and mild detergent. Rinse and dry thoroughly.
Exterior: Clean the door and housing with a damp cloth. Do not use abrasive cleaners or solvents.
Door Seals: Wipe the magnetic door gaskets clean to ensure a proper seal.
Condenser Coil: Vacuum the rear grille (if accessible) once or twice a year to remove dust.

Use the Eco mode for long-term storage.
Ensure the door seal is intact and clean.
Allow hot food to cool completely before freezing.
Open the door as infrequently and briefly as possible.
Ensure adequate ventilation space around the appliance.
Position away from heat sources.
