2-3. TURBO DRUM WASH (Except for WF-4020

A) FUNCTIONAL PRINCIPLE

■ Pulsator rotates right & left direction by motor driving force and drum rotates in the opposite direction to
the pulsator by inertia force & motor driving force, that is achieved by the new clutch and the new drain
motor, while only pulsator rotates right & left in a conventional washer.

2-4. REED SWITCH FOR APPLIANCE SAFETY(WF-402, T652A, T452A)

2-5. BALL PRESSURE SENSOR

Interrupt system of reed S/W is differed from safety S/W incorporated in the
previous models. Reed S/W is located on PWB ASM and operated with a magnetic
incorporated inside of Lid-B systemically. If Lid is the closed position, the magnetic
operates the contact of Lid S/W. In this case, the machine can do the normal
operation because the current pass through the contacts. On the other hand, the
contacts is open after Lid is the open position, the machine is stoped because the
magnetic is far from the Reed S/W. So do not place any electric appliance with a
charging battery, magnetically-driven appliance and magnetic body on the washer.
It makes misoperation of washing machine process.

To detect unbalance, the electronic sesing system is used which is differ from safety
S/W incoporated in the previous models. In the abnormal operation like unbalance
of clothes during spinning, etc, the ball inside of sensor is moved. In this case the
inductance of sensor is differ from the initial condition. So micom sense the
unbalance condition by ball movement. Ball pressure sensing system is higher
safety performance, sesing vertical movements and no deformation and noise by
over of safety S/W.

2-7. AUTOMATIC CORRECTION FOR THE UNBALANCED LAUNDRY

DURING SPINNING

When an unbalance of laundry occurs during spinning the unbalance will be automatically corrected
1times but 2nd unbalance will make the machine stop and “UE” is on the DISPLAY.
In that case, open the lid, correct the unbalance and press the START/PAUSE button.

2-8. LID SWITCH FOR APPLIANCE SAFETY (WF-T851, T902)

Interrupt system of LID SWITCH is differed from SAFETY SWITCH incorporated in the others models. LID
SWITYCH is located on TOP COVER and operated with a magnetic incorporated inside of LID-B
systemically. If LID is the closed position, the magnetic operates the contact of LID SWITCH. In this case,
the machine can do the normal operation because the current pass through the contacts. On the other hand
the contacts is open after LID is the open position, the machine is stopped because the magnetic is far from
the LID SWITCH.

2-6.TRIPLE WATER FALL SYSTEM

󱇧

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 operates during
the washing or rinsing process, water below the pulsator is sucked upwards by the rotation of
the pulsator vanes, creating a water flow as shown in Fig 1.
The water is then discharged from the upper part of the tub through the water channel
provided. circulating water with level and clothes load only and regular water flow as shown
in Fig 2.

2-9. NEW UNBALANCE SENSOR (OPTICAL BALL SENSOR) / WF-T851, T902

To detect unbalance, the optical sensor, BALL SENSOR, is used, which is differed from SAFETY SWITCH
incoporated in others models. In normal operation, +5 of voltage is applied between DIODE and TR. In the
abnormal operation like unbalance of clothes during spinning, etc, the ball inside of case is moved from the
hole. In this case any voltage is not applied between DIODE and TR. That is unbalance detection system of
this model.

2-10. AUTO POWER OFF

Power is automatically cut 10 seconds after wash progrom finishes.

A.HOW TO INSTALL THE WASHING MACHINE

󱇧󱇧

Selection of the installing place

Install the washer on the horizontal solid floor. If the washer is installed on an unsuitable fioor,
it could make considerable noise and vibration.

󱇧󱇧

Do not install the washer in the following places

··

Where the washer is exposed to direct sunlight.

··

Near a heater or heating appliance.

··

Where the washer is exposed to freezing temperatures.

··

In damp environments such as bathrooms or harmful

environments such as near a coal gas source.

The proper installation of the washing machine can increase the wash effectiveness and the
life of it.

If the washer is installed on an inclined floor, it could make considerable noise and vibration
and could cause a malfunction.

Use the height adjust rubber to adjust the washing so that it sits properly.

· Install the washing machine on a level and firm surface.

· Keep the washing machine more than 10cm from the wall to prevent vibration nois

during spinning

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

·Wooden floors may need reinforcing to prevent the normal vibration which occurs with an
unbalanced load.

B.HOW TO LEVEL THE WASHING MACHINE

· Check the level of the washing machine using a spirit level on the side of the
washer cabinet

· You can check the level also by visually lining up the washer with the fills, adjacent walls or cabinets.

󱇧󱇧 HHoorriizzoonnttaall SSeettttiinngg

· You can level the washer using the A.L spindle fitted to the cabinet.

·

Screw the A.L SPINDLE legs up or down as required.

· Additional height adjustment plates are provided in the accessory bag. These fit

under A.L SPINDLE if required to allow for greater adjustment of the legs.

· When washing machine does not even out, turn A.L SPINDLE right or left to be level.

· Should the height adjustment exceed the maximum allowed by the A.L SPINDLE,please height

adjustment plates provided under the legs as shown in the diagram.

1.

Fit the machine end of the drain hose to the outlet of
the drain pump and tighten the clamp.

2.

Put the other end of the drain hose over the
standpipe or wash tub.

3.

Fit the plastic holder into either holes for the holder
at the rear of the machine. The holder is possible to
fit at either direction according to location of the
standpipe. Make sure that the holder keeps firmly
the drain hose so that the drain hose should not fall
down as shown in the fig.
(WF-T851, T853, T802, T852)

❏ NOTE

:

●

To prevent syphoning, the drain hose should not
extend more than 50 mm from the end of the
hose guide.

●

The discharge height should be approximately

0.9~1.2m from the floor.

●

You machine requires a floor drainage slope (or hole) that will SAFELY DISPOSE of the FULL FLOW of any
water that may leak out should the machine malfunction.
It is therefore the OWNER'S RESPONSIBILITY to make sure this machine is installed in an area with a
drain hole (or slope) that will prevent any possibility of water damage to floor coverings or property.

● Check that sealing washers are firmly seated.

● Attach the curved end of the hose to the inlet valve of the washing machine; Tighten the

coupling nuts securely by hand. (Fig. 1)

● Attach the stsraight end of the hose to the tap.

Tighten the coupling nuts securely by hand. (Fig. 2)

● Either hose can be attached to hot inlet valve and tap.

● Turn on the taps and check for leaks. Tighten the coupling nuts firmly if there is any

leakage. If water pressure is strong, close the water tap completely then open it slightly.

● Do not install the washer where it is directly exposed to sunlight, wind, rain etc.

● Plug the power cord of this washer into a properly installed standard power point that is switched & earthed.

● Your machine requires a floor drainage slope(or hole) that will SAFELY DISPOSE of the FULL FLOW of any water that may leak

out should the machine malfunction. It is therefore the OWER’S RESPONSIBILITY to make sure this machine is installed in an
area with a drain hole (or slope) that will prevent any possibility of water damage to floor coverings or property.

● Permissible water temperature : Max 70ºC (160ºF)

● Permissible water pressure : Max 116psi (800kpa, 8kg/cm2), Min 4psi (30kpa, 0.3kg/cm2)

● If water temperature & pressure is greater than above, it may cause damage to the machine. If you have uncontrolled water

temperature & pressure you should fit a temperature &pressure relief valve to ensure that water temperature & pressure relief
valve to ensure that water temperature & water pressure remains within the safe limits. Consult a plumber or electrician if you are
unable to adjust water temperature and pressure.

● Do not over tighten the coupling nuts with a tobl. Inlets are plastic : Do not strip or corssthread.
