WARNING! Do not block air vents inside freezer. Ensure packages are sealed to prevent freezer burn.
Automatic defrosting system eliminates ice buildup.
How it works: A fan circulates cold air evenly. Evaporator coils periodically heat to melt frost; water drains to evaporation tray.
Benefits: No manual defrosting needed, consistent temperature, better energy efficiency, more storage space (no ice buildup).
Note: Slight humming during defrost cycle is normal. Ensure drainage hole at back is not blocked.
Unplug before cleaning. Use mild detergent and soft cloth.
