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.
25cm10Cm
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.
Never install in these places
●The place where it would be exposed to direct sunlight.
●The place nearby a heater or heat appliance.
●The place where it would be supposed to be frozen in winter.
●The kitchen with coal gas and a damp place like a bathroom.

■ 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
1Pull down the collar of the inlet hose to separate it from the water tap adapter.
2Loosen the four screws at the water tap adapter, but don’t loosen the screws until they are separated from the water tap adapter.
3Connect the water tap adapter to the water tap and tighten the four screws evenly with pushing up the adapter so that the rubber packing can stick to the water tap tightly.

6 CONVENIENCE
4. FEATURE AND TECHNICAL EXPLANATION
Feature of the Washing Machine
1 First applying the Radical Technology in the world ... go beyond washing, sterilize your clothes and deodorize a bad smell.
2 The first air bubble washing system in the world.
3 Quiet washing through the innovational low-noise design.
4 Improving washing performance by more than 35%, while reducing power consumption by 40%. 5 The laundry detergent dissolves well in water because of the air bubble washing system.
6 The adoption of the water currents to adjust the unbalanced load. 7 One-touch operation system.
Water Current to Adjust the Unbalanced Load
It is a function to prevent eccentricity of the clothes after wash by rotating pulsator C.W and C.C.W for 35 seconds.(But, the SUIT course have no operation of the water currents to adjust the unbalanced load.)
EFFECT
It reduces vibration and noise effectively while spinning.

Automatic Water Supply System for Blanket Wash
The water level would be lowered because the blanket absorbs water at the beginning of washing. Therefore, after 2 minutes, the operation is interrupted to check the water level, and then the water is supplied again until the selected water level is reached.

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.

8 FEATURE
Automatic Unbalance Adjustment
This system is to prevent abnormal vibration during intermittent spin and spin process.
FUNCTIONAL PRINCIPLE
1.When the lid is closed, the contact lever A of the safety switch 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. ASS’Y gets “OFF” signal from the safety switch, spin process is stopped and rinse process is started automatically.
4.If the safety switch is operated due to the unbalance of the tub, the program is stopped and the alarm is given.

Circulating-Water Course and Lint Filter
CIRCULATING-WATER
The washing and rinsing effects have been improved by adopting the water system in which water in the tub is circulated in a designed pattern.
When the pulsator rotates during the washing or rinsing process, the water below the pulsator fans creates a water currents as shown in figure.
The water is then discharged from the upper part of the tub through the water channel. About 40 L/min. water is circulated at the ‘high’ water level, standard wash load and standard water currents.

FEATURE 9
Lint Filter
Much lint may be obtained according to the kind of
clothes to be washed and some of the lint may also Filter stick 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.
HOW TO REPLACE LINT FILTER
1 Pull the filter frame upward.
2 Turn the lint filter inside out, and wash the lint off with water 3 Return the filter as it was, and fix the filter frame to the slot
