Benefits: Consistent temperature, no ice buildup, energy efficient.
Maintenance: Ensure air vents are not blocked by food items.
Drainage: Condensed water evaporates automatically; no drain pan to empty.

Note: During defrost cycles, slight noise may occur; this is normal operation.

Energy Saving Tips

Maximize efficiency and reduce electricity consumption.

Set optimal temperature: -18°C (0°F) is sufficient for most foods.
Minimize door openings: Plan removal of items to reduce cold loss.
Ensure proper seals: Check door gaskets regularly for tight closure.
Allow hot food to cool: Never place warm food directly in freezer.
Maintain ventilation: Keep rear and side clearances as specified.
Use Super freeze only when necessary: Deactivate after 24 hours.
