Energy Saving Tips

Maximize efficiency and reduce electricity consumption.

1. Set optimal temperature: -18°C is sufficient for most frozen foods.
2. Minimize door openings: Plan removal of items to reduce cold loss.
3. Ensure proper sealing: Check door gasket regularly; replace if damaged.
4. Allow hot foods to cool before freezing.
5. Keep condenser coils clean (located at rear).
6. Position away from heat sources (oven, radiator, direct sunlight).
7. Defrost manually if ice exceeds 5mm (though NoFrost minimizes this).

Note: Full freezers are more efficient than empty ones. Use water bottles to fill empty space if needed.

Maintenance & Cleaning

Unplug before cleaning. Never use abrasive cleaners, scouring pads, or solvents.

1. Exterior: Wipe with soft damp cloth and mild detergent. Dry thoroughly.
2. Interior: Clean shelves and baskets with warm water and baking soda solution.
3. Door gasket: Clean with water only; check for damage.
4. Condenser: Vacuum rear coils annually to maintain efficiency.
5. Drain hole: Check and clear if present (though NoFrost reduces condensation).

CAUTION! Do not use steam cleaners. Never pour water into appliance. Avoid electrical components when cleaning.
