Do notuse the area behind the refrigerator for storage of anything,especially combustible materials, especially gasoline andother flammable vapors and liquids.Defrosting:The freezer plates of the refrigerator operate at below freezingtemperature and will naturally form frost from humidity, which isalways present in the air. The humidity inside the refrigeratorincreases:- with higher outside temperature and humidity.- with the storage of non-sealed fresh foods or warm foods.- with the amount of time that the door(s) are open.- with any air leakage into the refrigerator.It is normal for frost to collect inside the refrigerator. Excessfrost decreases the cooling performance of the refrigerator.Defrost the refrigerator as necessary:- Remove all food from the refrigerator.- Turn the refrigerator OFF.NOTE: Defrosting the refrigerator makes excess water insidethe refrigerator, which falls onto the drip tray andflows to the outside of the refrigerator through thedrain tube.- Put dry towels (etc.) inside the refrigerator to help removethe excess water.CAUTION: High temperatures can cause the insidesurfaces of the refrigerator to warp or melt. Do not usepans of HOT water, a hair dryer, or any other hightemperature devices to defrost the refrigerator. Do notuse any hard or sharp objects to remove frost. Damageto the interior of the refrigerator can occur.- To increase the speed of defrosting, put pans of WARMwater in the refrigerator.- Remove the wet towels (etc.) and dry the interior.- Start up the refrigerator.- Allow the refrigerator to cool down.- Return all food to the refrigerator.Cleaning:A good time to clean the refrigerator is just after you defrost it.Clean the inside of the refrigerator as often as necessary toavoid food odors:- Remove all food from the refrigerator.NOTE: Do not use abrasive cleaners, chemicals, orscouring pads because they can damage theinterior of the refrigerator.- Wash the interior with a mild cleaner or a solution of liquiddish detergent and warm water.- Rinse with a solution of baking soda and clean water.- Dry with a clean cloth.- Put all food back into the refrigerator.To remove and clean the drip tray:- Make sure that the drip tray is empty of water.- Pull the drain tube plug out from the inside of the drip trayand out of the drain hose.- Pull the drip tray down to remove from the slots in therefrigerator cabinet.- Clean the drip tray.- Put the drain tube plug down into the drip tray and push thedrip tray back into the original position.- Push the drain hose back onto the drain tube plug.Door sealing:If the door does not seal correctly, excess frost will collect insidethe refrigerator.
