Setup and Installation
Unpacking
Carefully remove all packaging materials. Inspect the freezer for any damage. Report any damage to your retailer immediately. Keep packaging materials away from children.
Placement
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.

Initial Power-On
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.

Operating Instructions
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.
- Freezer Mode: Ideal for long-term storage of frozen foods. Maintains temperatures typically below -18°C.
- Chiller Mode: Suitable for keeping items very cold but not frozen, such as fresh meat or beverages for short periods.
- Refrigerator Mode: 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.

Loading Food
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.
Maintenance and Care
Cleaning the 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.
Defrosting
Frost buildup can reduce the efficiency of your freezer. Defrost the appliance when the frost layer reaches approximately 5-10 mm thickness. To defrost:
- Unplug the freezer.
- Remove all food items and store them in another freezer or cooler.
- Leave the lid open to allow the frost to melt naturally. You can place towels at the bottom to absorb water.
- Once defrosted, clean and dry the interior thoroughly.
- Plug the freezer back in and allow it to cool before returning food.
Do not use sharp objects or heating devices to speed up defrosting, as this can damage the appliance.
Cleaning the Exterior
Wipe the exterior surfaces with a soft cloth dampened 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.
