Daily Maintenance Daily Maintenance Before cleaning, be sure to disconnect the plug from outlet, dispense water and allow to cool the unit. Main unit and lid Clean with a damp, well-wrung cloth. ● Do not wet or soak the main unit in water. If water enters the main unit from the bottom or from the dispensing spout, it can also get into the electrical components in the main unit and may cause a malfunction. ● Do not use detergents. (They may leave an odor.) ● Do not use benzine or thinner. (They may damage the surface.) Inner container Clean with a wet sponge. ● Do not use polishing powder, a scrub brush or a nylon brush. They may damage the fluororesin finish of the inner container. About "Scale" While you are using this unit, minerals contained in the water (like calcium) can get stuck on the inner comtainer or on the mesh filter. This is called "scale", and it is harmless. ● Milky-white gritty surface (caused by calcium) ● White or glittering floating material (crystals of minerals) ● Discoloration in the finish like dark brown, gray, or green areas (metallic ion made on the fluororesin covering) These are not discoloration or corrosion of the inner container itself, nor are they flakes from the fluororesin covering. Clean the inner container using citric acid. (See P.21) Mesh filter Clean the filter with a brush. When filter is clogged, water does not flow smoothly. * After cleaning the filter, be sure to reattach it to the inner container. When storing the unit ● Dry it thoroughly. ● Put it into a plastic bag and seal the bag. 20
