The refrigerator has a Power Failure Memory function. In the event of a power failure, the current working state (mode and temperature settings) will be memorized and maintained until power is restored.

If a fault occurs, the display will show a fault code by flashing specific temperature level icons. Although the refrigerator might still have cooling/freezing functions, contact a maintenance specialist.

Use the freezer for low-temperature freezing and long-term storage.

Do not place fresh and frozen food directly next to each other, as the frozen food might thaw.

Divide large amounts of fresh food (meat, fish) into smaller portions before freezing for quicker freezing and easier use.

Follow storage times recommended by manufacturers. If no information is provided, do not store frozen food for longer than three months.

When buying frozen food, ensure it was stored at a suitable temperature and the packaging is intact.

Keep frozen food in suitable individual packages to prevent contamination.

Consume thawed/defrosted foods immediately; do not refreeze.

In case of power failure, check if stored frozen food is still edible. If so, store it in a sufficiently cool place or another appliance.

To defrost, remove food and let it thaw at room temperature or in the refrigerator. Use a microwave’s defrost function for quick thawing.

If defrosting only part of a pack, remove the needed portion and immediately close the rest to prevent freezer burn and ice formation.

To reduce moisture and ice build-up, always store liquids in sealed containers.

Avoid storing uncovered liquids, as frost concentrates in the coolest parts and requires more frequent defrosting.

Cool warm foods to room temperature before placing them inside.

Ensure adequate air circulation; do not let foods or containers touch the back wall, as they could freeze.

Minimize door openings.

Store meat and cleaned fish in packages or plastic foil for 1-2 days.

Store fruits and vegetables without packaging in the designated fresh fruit and vegetable section.

Attention: Storing too much food right after initial connection may adversely affect freezing performance.

Note: Storing food for too long or at inappropriate temperatures can cause quality loss, spoilage, and potential food poisoning. The minimum freezing temperature should ideally be -18°C (0°F) or colder.

Recommended Maximum Storage Times (at -18°C or colder):

Stew, ice cream, sausages, bread: 2-6 months.

Fish, shrimp, lamb, meat: 4-8 months.

Vegetables, fruits, poultry, beef: 6-12 months.

General Cleaning:

Clean the interior regularly to avoid odors. Use a soft cloth or sponge with a solution of two tablespoons of baking soda and a quart of warm water. Rinse with water and wipe clean. Let it dry naturally before turning power on.

Clean hard-to-reach areas (narrow gaps, corners) regularly with a soft rag, soft brush, and auxiliary tools (like thin sticks) if needed.

Clean the door gasket regularly with a soft cloth dampened with soapy water or diluted detergent. Check for debris.

Clean the outer surface with a soft cloth dampened with soapy water or detergent, then wipe dry.

Eliminate dust on the back of the unit at least once a year.

What NOT to Use: Do not scrape frost/ice with sharp objects. Avoid sprays, electric heaters, steam cleaners, or other heat sources. Do not use soap, detergent, scrub powder, spray cleaner, hard brushes, steel balls, wire brushes, abrasives (like toothpaste), organic solvents (alcohol, acetone), boiling water, acid, or alkaline items, as they can damage surfaces and cause odors. Do not rinse directly with water.

Defrosting:

The appliance defrosts automatically. However, if the freezer door is opened frequently or for too long, a thick frost layer may form.

If frost is too thick, defrost when food stocks are low:

1. Remove food and accessories baskets.

2. Unplug the appliance.

3. Leave the doors open and ventilate the room thoroughly.

4. Once defrosting is complete, clean the freezer as described above.

CAUTION! Do not use sharp objects to remove frost. Only switch the appliance back on and plug it in after the interior is completely dry.

Following the arrow direction shown in the PDF diagram, use both hands to squeeze the tray and push it upward to remove it.
