9 3-2. BEFORE STARTING TO WASH Care Labels • Look for a care label on your clothes. This will tell you about the fabric content of your garment and how it should be washed. Sort clothes into loads that can be washed with the same wash cycle, water temperature, and spin speed. Sorting To get the best results, different fabrics need to be washed in different ways. • SOIL (Heavy, Normal, Light) Separate clothes according to the type and amount of soil. • COLOR (Whites, Lights, Darks) Separate white fabrics from colored fabrics. • LINT (Lint producers, Collectors) Separate lint producers and lint collectors. Lint Producers Terry cloth, Chenille, Towels, Diapers Lint Collectors Synthetics, Corduroy, Permanent Press, Socks Check before Loading • Check all pockets to make sure that they are empty. Things such as nails, hairclips, matches, pens, coins, and keys can damage both your washer and your clothes. • Mend any torn garments or loose buttons. Tears or holes may become larger during washing. • Remove belts, underwires, etc. to prevent damage to the machine or your clothes. • Pretreat any dirt and stains. • Make sure the clothes are washable in water. • Check the washing instructions. • Remove any paper or tissue in the pockets. • WIRE Loading Do not wash fabrics containing flammable materials(waxes, cleaning fluids, etc.). Load Size The WATER LEVEL should just cover the clothes. Adjust the load size accordingly. Loosely load clothes no higher than the top row of holes in the washer tub. To add items after washer has started, press the Start button and submerge additional items. Close the lid and press the Start button again to restart. ※ Do not wash waterproofed fabrics (such as skiing outfits, diapers, or nappy auto seat covers.) Light and Large-sized clothing Clothes like downs and woollens are light weight, large and float easily. Use a nylon net and wash them in a small amount of water. If the laundry floats during the wash cycle, it may become damaged. Use dissolved detergent to prevent the detergent from clumping. ※ Do not wash water-proof textilles (Skling outfit, baby diaper, nappy automobile seat covers.) Long laundry items Use nylon bag nets for long, DELICATES items. For laundry with long strings or long length, a bag will prevent tangling during washing. Fasten zippers, hooks, and strings to make sure that these items don't snag on other clothes. ※ The nylon washing bag is not supplied by LG. Pretreatment on stains or heavy soil • Pretreat shirt collars and cuffs with a pre-wash product or liquid Detergent when placing them in the washer. Before washing treat special stains with bar soaps, liquid detergent or a paste of water and granular detergent. • Use a pretreat soil and stain remover. Treat stains AS SOON AS POSSIBLE. The longer they are left, the harder they are to remove. (For more detail refer to page 13) WIRE WARNING Fire Hazard Never place items in the washer that are dampened with gasoline or other flammable fluids. No washer can completely remove oil. Do not dry anything that has ever had any type of oil on it (including cooking oils). Doing so can result in death, explosion, or fire.

10 Using Water Water Temperature • The machine sets the appropriate temperature automatically according to the wash program . You can override the preset selection by pressing the WASH/RINSE temperature. button. • The temperature of the water impacts the effectiveness of all laundry additives and therefore, the cleaning results. • We recommend temperatures of: - HOT 120°F (120-140°F) White items, diapers, underclothing and heavily soiled, colorfast items. - WARM 90°F (85-105°F) Most items - COLD 66°F (65-75°F) Only very bright colors with light soil. • When washing in COLD water additional steps may be needed: - Adjust Detergent amount and pre-dissolve Detergent in WARM water - Pretreat spots and stains - Soak heavily soiled items - Use appropriate bleach * Temperature below 18°C (65°F) will not activate laundry additives and may cause lint, residue, poor cleaning, etc. In addition, detergent manufactures and care labels define COLD water as 26~29°C...(80-85°F). If the temperature of the water in the tub is too cold for your hands, the detergent will not activate and clean effectively. Note If iron is present in the water the clothes may become an all-over yellow or they may be stained with brown or orange spots or streaks. Iron is not always visible. Installation of water softener or an iron filter may be necessary for severe cases.
