Food Storage Basket

Your Freezer has 1 or 2 removable basket. It allows you to store food more

accessibly or you can remove it if not needed.

Defrosting and Draining The Freezer

·Defrost whenever the frost becomes 5MM thick. Never use a sharp or metallic instrument to remove the frost as it may damage the cooling coils.(A punctured coil will void the warranty)

·Turn the temperature control to 0 position and unplug the unit. For draining, place a tray beneath the outer drain plug. Pull out the drain dial and rotate it so that the arrow points down ward. This will let the water flow out into the tray.

·Remove the drain plug from the inside of the freezer. Defrosting usually takes a few hours. To defrost faster keep the freezer door open. When done, push the drain dial in and turn the arrow to the up position. Re-plug the drain plug inside the freezer compartment. Note: monitor the container under the drain to avoid overflow.

·Wipe the interior of the freezer and replace the electrical plug in the electrical outlet.

·Rest the temperature control to the desired setting.
