always keep the refrigerator clean. Cleaning the refrigerator
is usually done after it is defrosted or put into storage. use
lukewarm weak soda solution to clean the interior liner of the
refrigerator. use warm water only to clean the finned evapora-
tor, gasket, ice tray and shelves.
NOTE! Never use strong chemicals or abrasives to clean these
parts, as the protective surfaces will be damaged. Do not spray
liquids near electrical outlets, connections or the refrigerator
components.
To keep the refrigerator operating efficiently and safely, peri-
odic inspection and cleaning of several components once or
twice a year is recommended:
Check the lower vent, upper vent and area between these
openings for any obstructions such as bird/insect nests,
spider webs, etc.
Make sure the refrigerator area is free from combustible
material, gasoline and other flammable vapors or liquids.
Clean the coils on the back of the refrigerator. use a soft
bristled brush to dust off the coils. •
