Configuração e instalação
Desembalando
Carefully remove all packaging materials. Inspect the freezer for any damage. Report any damage to your retailer immediately. Keep packaging materials away from children.
Colocação
Choose a suitable location for your chest freezer. Ensure it is placed on a flat, stable surface away from direct sunlight, heat sources (such as stoves, radiators), and extreme cold. Allow adequate ventilation space around the appliance (at least 10 cm on sides and back, 30 cm above). This ensures efficient operation and prevents overheating.

Inicialização
After placing the freezer, wait at least 2-4 hours before plugging it into a power outlet. This allows the refrigerant to settle. Plug the appliance into a dedicated, properly grounded electrical outlet. The freezer will begin to cool. Allow it to operate empty for several hours (e.g., 4-6 hours) to reach its operating temperature before loading food.

Instruções de operação
Multi-Mode Control Panel
Your Defy Multimode Chest Freezer features a control panel that allows you to switch between three operating modes: Freezer, Chiller, and Refrigerator. Refer to the markings on the control panel for specific settings. Use the dial or buttons to select your desired mode and temperature.
- Modo Freezer: Ideal for long-term storage of frozen foods. Maintains temperatures typically below -18°C.
- Modo Resfriador: Suitable for keeping items very cold but not frozen, such as fresh meat or beverages for short periods.
- Modo Refrigerador: Functions as a standard refrigerator, maintaining temperatures typically between 0°C and 5°C for fresh produce and dairy.
Using the Movable Basket
The freezer includes a movable basket designed for efficient organization of smaller or frequently accessed items. Place the basket on the designated ledge inside the freezer compartment. This helps prevent items from getting lost at the bottom of the freezer and allows for better air circulation.

When loading food, avoid blocking the air vents (if present) and ensure there is space for air to circulate. Do not overload the freezer. For optimal performance, allow hot foods to cool to room temperature before placing them inside.
Manutenção e Cuidados
Limpeza do interior
Before cleaning, always unplug the freezer from the power outlet. Clean the interior regularly with a solution of mild detergent and warm water. Rinse thoroughly and dry completely. Do not use abrasive cleaners, harsh chemicals, or sharp objects, as these can damage the interior surfaces.

- Desligue o congelador da tomada.
- Retire todos os alimentos e guarde-os em outro congelador ou caixa térmica.
- Deixe a tampa aberta para que o gelo derreta naturalmente. Você pode colocar toalhas no fundo para absorver a água.
- Após descongelar, limpe e seque bem o interior.
- Plug the freezer back in and allow it to cool before returning food.
Não utilize objetos pontiagudos ou dispositivos de aquecimento para acelerar o descongelamento, pois isso pode danificar o aparelho.
Limpeza do Exterior
Limpe as superfícies externas com um pano macio.ampened with mild detergent and water. Dry thoroughly. Regularly clean the condenser coils at the back of the freezer (if accessible) with a soft brush or vacuum cleaner to ensure efficient operation.
