DIRECTIONS

The opening must not be obstructed by carpeting when the washing machine is installed on a carpeted floor.

■■

Location Of Washer

Check location where washer will be installed. Make sure you have everything necessary for correct installation. Proper installation is your responsibility.

• Do not place or store your washer below 0˚C(32˚F) to avoid any damage from freezing.

• Install the washer on the horizontal sold foor.

NOTES

If the washer is installed on an unsuitable floor, it could make considerable noise, vibrate and cause a malfunction. If washer is not level, adjust the front leg(A) up or down for horizontal setting.

• Earthed electrical outlet(B) is required with 20cm of bottom back of washer cabinet.

• Hot and cold water faucets (C) must be within 1M of the upper back of the washer cabinet and provide water pressure 0.3kgf/cm

8kgf/cm

(2.94N/cm2-78.4N/cm2).

■■

Drain System

Never forget to install drain hose before operating your washer. The packing box is opened, there are a drain hose.

• Conect the drain hose to the drain outlet at the back side of the washer.

Non-Pump Model Pump Model

1 In case that it goes over a door sill.

Don’t let the height of the drain hose exceed 20cm from the bottom of washer.

2 In case of extending the drain hose.

Don’t let the total length exceed 3m.

3 Be careful that the end of the drain

hose is not immersed in water.

CONNECTION

FOR ORDINARY TAP

Connect the inlet hose adapter of the hose to the water inlet of the washer by turning it clockwise to be fixed tightly.

• Please check the rubber packing inside the inlet hose adapter of the hose.

Pull down the collar of the inlet hose to separate it from the water tap adapter.

Loosen the four screws at the water tap adapter, but don’t loosen the screws until they are separated from the water tap adapter.

Remove the tape, and screw connector B into connect A tightly.

Connect the inlet hose to the water tap adapter by pulling down the collar of the hose end.

Connect the water tap adapter to the water tap and tighten the four screws evenly while pushing up the adapter so that the rubber packing can stick to the water tap tightly.

■■

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 SCREW-SHAPED TAP

Insert the inlet hose adapter into the water inlet of washer and turn it to be fixed.

• Assert the packing in the inlet

Connect the inlet hose to the water tap by screwing the connector D tightly.

How To Clean The Filter

Remove the dirt from the inlet filter with a brush.

Pull the power plug out before cleaning it.

Turn off the water supply to the washer and separate the inlet hose.

Pull the inlet filter out.

CLEANING THE LINT FIL TER

CLEANING THE WATER INLET FIL TER

• Clean the filter when water leaks from the water inlet.

CLEANING THE DRAIN FIL TER

• In case of “U” shaped 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.

Return the filter as it was, and insert the filter frame into the slot.

Pull the Filter frame upward.

Turn the lint filter inside out, wash the lint off with water.

Put down the remained water in the hose. And put a container under the filter to collect water.

Turn the cap counterclockwise.

Pull out the filter assembly off the case of the main body.

Turn the cap clockwise tightly.

Clean the drain filter removing the foreign stuffs.

Put in the filter along the guiding prominence of the case. Please note the left position of the filter adjusting the groove to the guide rib.

Feature of the Washing Mac hine

1 The first air bubble washing system in the world. 2 Quiet washing through the innovational low-noise design. 3 The wash effectiveness is much more enhanced because of the air bubble washing system. 4 The laundry detergent dissolves well in water because of the air bubble washing system. 5 The adoption of the water currents to adjust the unbalanced load. 6 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 unbalnced load.)

EFFECT

It reduces vibration and noise effectively while spinning.

WATER FLO W

Automatic Water Supply System

The water level would be lowered because the clothes absorbs water at the beginning of washing. Therefore, after 60 seconds, the operation is interrupted to check the water level, and then the water is supplied again until the selected water level is reached.

EXPLANATION

FUNCTIONAL PRINCIPLE

1 The micom can remember the time from the begining of drain to reset point when the pressure switch reaches to

“OFF” point

2 In case of continuous draining, residual drain time is determined by micom.

Draining time as a whole = D + 40

Residual drain time. The time remembered by micom.

Automatic Drainning time Adjustment

This system adjusts the draining time automatically according to the draining condition.

EXPLANATION

This is the device to dispense the softener automatically by centrifugal force. This is installed inside the auto-balancer.

FUNCTIONAL PRINCIPLE

1 Softener stays in room (A) when poured into softener inlet. 2 Softener moves from (A) to (B) by centrifugal force during intermittent spin process. 3 Softener flows from (B) to (C) during rinse process next to intermittent spin. 4 Softener moves from (C) to (D) by centrigfugal force during second intermittent spin.

After spin process is finished, the softener is added into the tub through softener outlet.

FLOW OF THE SOFTENER

FLOW OF THE SOFTENER INSIDE OF THE BALANCER

HOW TO CHECK MOVEMENT

Pour a reasonable amount of “MILK” into softener dispenser and operate the washer with no load. In final rinse cycle, make sure that the milk is added into the tub through softener outlet.

NOTES

Outer tub

Water channel

Pulsator

This system is to prevent abnormal vibration during intermittent spin and spin process.

FUNCTIONAL PRINCIPLE

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. ASS’Y gets “OFF” signal from the safety switch, spin process are stopped and rinse process

is started automatically by P.C.B. ASS’Y.

4 If the safety switch is operated due to the unbalance of the tub, the program is stopped and the alarm is given.

CIRCULA TING-WA TER

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 vanes 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.
