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

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.

Condition

 

 

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.

Clutch Motor

<Fig 1>

<Fig 2>

■ 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.

2-7. 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.

2-9. 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.

Power is automatically cut 10 seconds after wash progrom finishes.

4. INSTALLATION INSTRUCTION

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.

10cm

·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.

15

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.

·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.

Holes for the Holder

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.

D. Flooding drainage

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.

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

 

 

CAUTION

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

<Fig.2>

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.
