1. SPECIFICATIONS NO.
2. STRUCTURE OF THE WASHING MACHINE The parts and features of your washer are illustrated on this page. Become familiar with all parts and features before using your washer. NOTE • The drawing in this book may vary from your washer model. They are designed to show the different features of all models covered by this book, Your model may not include all features. • HOT WATER TAP After using the washer, close the water tap. In case of the single valve model, there is no hot water valve.
3. DIRECTIONS FOR INSTALLATION AND USE INSTALLING PLACE Install the washer on a horizontal solid floor. If the washer is installed on an unsuitable floor, it could make considerable noise and vibration. Never install in these ● The place where it would be exposed to direct sunlight. 10Cm Keep the machine body more than 25cm apart from the wall surface. It will make easy cleaning the drain filter which is equipped at the back side of it. And if it comes into contract vibration may occur.
HOW TO CONNECT THE INLET HOSE Be careful not to mistake in supplying between the hot(maximum : 50˚C) and cold water. In using only one water tap or in case of attached one water inlet valve, connect the inlet hose to the cold water inlet valve. Do not over tighten : this could cause damage to couplings. FOR ORDINARY TAP 1 Pull down the collar of the inlet hose to separate it from the water tap adapter.
HOW TO CLEAN THE FILTER CLEANING THE LINT FILTER • This washer has two type of Lint Filter in order to increase lint filtering performance. Type I : It is assembled in the top area of Tub. 1 2 Pull the Filter frame upward. Turn the lint filter inside out, wash to the lint off with water. Lint Filter 3 Return the filter as it was, and insert the filter frame into the slot.
CLEANING THE DRAIN FILTER • In case “U” shape drain hose, this filter’s equipped at the back side of washer. • This drain filter is to screen the foreign stuffs such as threads, coins, pins, buttons etc ... • If the drain filter is not cleaned at proper time (every 10 times of use), Drain problem could be caused. 1 Put down the remained water in the hose. And put a container under the filter to collect water. 2 Turn the cap counter clockwise.
4. FEATURE AND TECHNICAL EXPLANATION FEATURE OF THE WASHING MACHINE 1 The first applying Radical Technology in the world....go beyond washing, sterilize your clothes and deodorize a bad smell.(optional function) 2 The first air bubble washing system in the world. 3 Quiet washing through the innovational low-noise design. 4 The wash effectiveness is much more enhanced because of the air bubble washing system. 5 The laundry detergent dissolves well in water because of the air bubble washing system.
FUNCTIONAL PRINCIPLE OF BUBBLE WASHING MACHINE ACROSS SECTION Air bubble Tub Outer tub Pulsator FUNCTIONAL PRINCIPLE Bubble Motor supplies the air from the bottom of outer tub to the inner space of pulsator, the air is dispersed by the rotation of pulsator. Air-bubble is created by the centrifugal force, and rises up. AUTOMATIC DRAINNING TIME ADJUSTMENT This system adjusts the draining time automatically according to the draining condition. Good draining The washer begins spin process after drainage.
AUTOMATIC UNBALANCE ADJUSTMENT This system is to prevent abnormal vibration during intermittent spin and spin process. FUNCTIONAL PRINCIPLE Contact of safety switch Lid closing 1 When the lid is closed, the safety switch contact is “ON” position. 2 In case that wash loads get uneven during spin, the outer tub hits the safety switch due to the serious vibration, and the spin process is interrupted. 3 In case that P.C.B.
LINT FILTER Much lint may be obtained according to the kind of clothes to be washed and some of the lint may also sticks to the clothes. To minimize this possibility a lint filter is provided on the upper part of the tub to filter the wash water as it is discharged from the water channel. It is good to use the lint filter during washing. Filter Filter Bleach Bleach Inlet Inlet Pulsator Pulsator HOW TO REPLACE LINT FILTER 1 Pull the filter frame upward.
GEAR MECHANISM ASS’Y The proper water currents is made by the rotation of pulsator at a low speed to prevent the damage to the small sized clothes. Sun gear Internal gear Planetary gear Motor 1800 r.p.m (60Hz) 1500 r.p.m (50Hz) Pulsator Gear unit as 1 revolution Motor V.BELT Gear Unit as 125-140r.p.m(60Hz) 130-150r.p.m(50Hz) Spinner Pulley 5 revolutions 710-740r.p.m(60Hz) 640-675r.p.m(50Hz) Tub Gear pulley Directly V-belt 12 FEATURE Pulsator 710-740r.p.m(60Hz) 640-675r.p.
5. DIRECTIONS FOR DISASSEMBLY AND ADJUSTMENT Warning BEFORE ATTEMPTING TO SERVICE OR ADJUST ANY PART OF THE WASHING MACHINE, DISCONNECT THE POWER CORD FROM THE ELECTRIC OUTLET. GEAR MECHANISM ASS’Y REPLACEMENT GEAR MECHANISM ASSY REPLACEMENT 1 Raise the top plate on the outer cabinet. 2 Loosen four screws mounting outer tub cover and 3 Remove the cap pulsator from the pulsator assy by using screw driver remove outer tub cover from the tub ass’y.
7 Remove the tub i assy. 8 Lay the front of the washer on the floor. 9 Remove four special bolts of gear protect by using a box wrentch and remove gear protect. 0 Remove the V-belt. q Remove four special bolt of gear mechanism assy by w Pull out the gear mechanism assy. using a box wrentch. NOTES To assemble the gear mechanism ass’y, reverse the disassembly procedure.
MOTOR SYNCHRONOUS AND VALVE REPLACEMENT (NON PUMP MODEL) 1 Lay the front of the washer on the floor. 2 Loosen two special screw of motor synchronous. 3 Take out the wire of motor synchronous from the braket. 4 Separate the motor synchronous from the base. 5 Turn the valve by using screw driver as shown in pic- 6 Remove the valve lid from the valve drain assy. ture.

HOW TO CHECK THE CLUTCH SPRING PROBLEM PROBLEM 1) THE LAUNDARY IS IN THE SPIN TUB UNEVENLY WHEN JUST STARTING SPIN PROCESS. 2) THEREFORE, IT CAUSE THE SERIOUS NOISE AND VIBRATION WHEN WASHING AND SPINNING PROCESS OR SUPPLING WATER IRREGULARY WHEN SPINNING PROCESS AND CAUSE SHORT OF SPIN PERFORMANCE. CHECKING METHOD IN THIS CASE, YOU MUST EMPTY THE SPIN TUB FIRST. 1) TO CHECK THE REVOLUTION OF SPIN TUB. IF THE SPIN TUB DOES NOT REVOLVE AND ONLY THE PULSATOR IS TURNING, THAT IS CLUTCH SPRING DEFECT.
THE PROCESS OF DISASSEMBLE Disassemble 1 No. Process Remove the protector 1 Notice Use wrench or driver - ratchet handle - extension bar - socket : 10mm Release screws marked 4-point Remove the v-belt 2 Loosen the fastening nut Use fixing jig for pulley as to see fig 1.
