Power failure: Keep door closed; food stays frozen for up to [hours] if full.

WARNING! Do not store explosive substances or carbonated drinks in glass.

NoFrost Technology

Automatic defrosting system eliminates ice buildup.

How it works: Cold air circulates evenly; moisture is carried to evaporator where it freezes. Heater periodically melts ice; water drains to evaporation tray.

Benefits: No manual defrosting; consistent temperature; better food preservation.

Note: Slight humming during defrost cycle is normal.

Care & Cleaning

Unplug before cleaning. Use mild detergent and soft cloth.

Exterior: Wipe with damp cloth; dry immediately.
Interior: Remove shelves/baskets; wash with warm soapy water.
Seals: Clean door gaskets to maintain seal.
Condenser: Vacuum rear grille annually to remove dust.
Evaporation tray: Located at rear; empty if necessary (rarely required with NoFrost).

CAUTION! Do not use abrasive cleaners, solvents, or steam cleaners.
