4 2. INSTALLATION INSTRUCTIONS 2-1. HOW TO ADJUST LEVEL 4 Raise Lower CAUTION • The ventilating openings in the base area must not be obstructed by carpeting. • Install the washing machine on a level and firm surface. There should be no more than 1° of variation. • Wooden floors may need reinforcing to prevent the normal vibration which occurs with an unbalanced load. • Do not install the washer on an inclined floor. Improper installation of the washer may cause noise and malfunctioning. 1 Installation area • Install the washer on a firm, flat surface. • If the washer is installed on an unsuitable floor, it could make considerable noise and vibrate. 2 3 Checking level • Open the lid, check if the washer is correctly leveled by looking down from the top. If the tub is not centered in the opening, then the washer is not level. No shims. It would be dangerous. If the floor is that far from being level, it is a floor problem and not a washer problem. Set Leveling feet • Adjust the leveling feet, Turn clockwise to raise the washer or counterclockwise to lower it. Checking slope • If installation surface is tilted, the washer will vibrate. Do not install on a sloping floor. Downloaded from www.Manualslib.com manuals search engine

Water tap Rubber Seal Water Supply Hose 1 Be sure there is a gasket in both ends of the hose. Push the water supply hose up so that the rubber packing within the hose can adhere completely to the tap. 2 Connect the water supply hose to the tap. Run a couple of gallons of water through the hoses into the drain or a bucket to flush any particulate or contaminate. 3 Check water leakage. After connecting the hose, open the tap to check for any water leakage. Connecting Water Supply Hose to the Machine • Be sure there is a gasket in the end of the hose. • Connect the hose to the appropriate inlet vale (hot or cold) of the washing machine and tighten if firmly. • Turn on the water and check for leacks. • Always install new hoses with a new washing machine Do not re-use old hoses. • Relplace the hoses every five years. Screw Type 2-2. CONNECTING WATER SUPPLY HOSE 6 Before connecting the water supply hose to the water tap, check the hose type and then choose the correct instruction here below.

7 2-3. CONNECT THE DRAIN HOSE 35"~47" (0.9~1.2m) 35"~47" (0.9~1.2m) • Connect the drain hose to the outlet of the drain pump located at the rear of the washing machine. Attach the clip to the drain hose. • And then push it toward the body of the washing machine as indicated by the arrow. • Check that the drain hose is hung up over the edge of the laundry tub. • Do not use an extension hose. NOTE : • The drain hose should always be properly secured to the drain or standpipe. Failure to secure the drain hose properly can result in flooding and property damage. • The end of the drain hose should be placed 39" (99 cm) above the floor. • The drain must be installed in accordance with any applicable local codes and regulations. • Make sure that the water lines are not stretched, pinched, crushed, or kinked. • Do not insert the drain hose more than 12” (30 cm) into the drain pipe to avoid siphoning and odor build-up. Cable Tie Cable Tie WARNING: • The washer should never be installed or stored in a location subject to freezing temperatures. If the washer was exposed to freezing temperatures prior to installation, allow it to stand at room temperature for several hours before use. Damage to the water lines and internal mechanisms of the washer can result. • Water supply pressure must be between 14.5 psi and 116 psi (100 ~ 800kPa) If the water supply pressure is more than 116 psi, a pressure reducing valve must be installed. If you have uncontrolled water temperature and pressure you should fit a temperature and pressure relief valve to ensure that water temperature and water pressure remain within the safe limits. Consult a plumber or electrician if you are unable to adjust water temperature and or pressure. Failure to do so can result in damage to the machine. • Plug the power cord of washer into a properly grounded outlet. Failure to do this can result in shock or serious injury.

WIRE 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. • Be sure the wire supports in undergarments are secure and will not become loose in the washer. 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 woolens are lightweight, 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 (Skiing outfit, baby diaper, nappy automobile seat covers.) Long laundry items Use nylon bag nets for long, delicate 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 net bag can be purchased locally. 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 powdered 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 14-15) Downloaded from www.Manualslib.com manuals search engine

10 1) 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 water temperature icon. Touch the arrow buttons up or down until your desired temperature setting is displayed. • 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. Downloaded from www.Manualslib.com manuals search engine
