5. Door reversal (if needed): Follow instructions in manual to change door hinge side.

WARNING! The freezer is heavy; use two people for lifting and moving. Ensure the floor can support the weight.

First-Time Setup

After installation, allow the freezer to stabilize before loading food.

1. Initial cooling: Turn on the freezer and set to the recommended temperature (e.g., -18°C / 0°F). Let it run empty for 2-3 hours.
2. Temperature setting: Use the control panel to set desired freezing level.
3. Load food: Place food items evenly, avoiding overpacking to ensure proper air circulation.
4. Fast Freeze: Activate Fast Freeze function when adding large quantities of unfrozen food.

CAUTION! Do not place hot food directly into the freezer; allow it to cool to room temperature first.

4. Label and date all food packages for easy identification.
5. Avoid blocking air vents inside the freezer to maintain consistent temperature.

Tip: Group similar items together and keep an inventory list on the door.

NoFrost Technology

Automatic defrosting system that prevents ice buildup.

1. How it works: A fan circulates cold air evenly, while a heating element periodically melts any frost on the evaporator.
2. Benefits: No need for manual defrosting; consistent temperature; better food preservation.
3. Maintenance: Ensure air vents are not obstructed by food items.

Note: A small amount of condensation may appear during the defrost cycle; this is normal.

Energy Saving Tips

Maximize efficiency to reduce electricity consumption.

• Set temperature to -18°C (0°F) for optimal efficiency.
• Ensure door seals are clean and tight; replace if damaged.
• Open door as infrequently and briefly as possible.
• Place freezer in a cool location, away from ovens or heaters.
• Regularly defrost if not using NoFrost model (not applicable to IFd 3904 Pure).
• Keep freezer at least ¾ full for best thermal mass; use water bottles if needed.

Care & Cleaning

Unplug before cleaning. Use mild detergent and water; never use abrasive cleaners.

1. Interior: Remove all food. Wipe shelves, drawers, and walls with a soft cloth dampened with a solution of warm water and mild detergent. Dry thoroughly.
2. Exterior: Clean door and handle with a damp cloth. For stainless steel models, use appropriate cleaner.
3. Door Seals: Clean gaskets with water and detergent to maintain seal integrity.
