How To Install On An Inclined Place
The place where it would be exposed to
direct sunlight.
The place nearby a heater or heat appli-
ance.
The place where it would be supposed
to be frozen in winter.
The kitchen with coal gas and a damp
place like a bathroom.
NOTES

FEATURE OF THE WASHING MACHINE
The first applying Radical Technology in the world....go beyond washing, sterilize your clothes and deodorize a
bad smell.
Quiet washing through the innovational low-noise design.
The adoption of the water currents to adjust the unbalanced load.
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 30
seconds.(except for the course “soft” and “tub self-clean”.)
EFFECT
It reduces vibration and noise effectively while spinning.
WATER FLOW
FUNCTION FOR SOAK WASH
DISPLAY THE RESIDUAL TIME
When the SOAK WASH is selected, the total wash time increases because 20 minutes(“normal” , “self-clean”
and “water saving” course ) or 30 minutes(”heavy” and “fine purifition” course) for soak process are added to
PROGRESS
AUTOMATIC WATER SUPPLY SYSTEM FOR WASH
The water level would be lowered because the washings absorbs water at the beginning of washing. Therefore, after
some secs, the operation is interrupted to check the water level, and then the water is supplied again until the selected water level is reached.
" " mark indicates the operation of the water currents to adjust the unbalanced load.

CIRCULATING-WATER
The washing and rinsing effects have been
improved by adopting the water system in
wh i ch wa ter i n the tub i s cir c ulate d 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
par t of the tub through the water channel.
About 40 L/min. water is circulated at the "8"
water level, standard wash load and standard
water currents.
When the START/PAUSE button is pressed, the residual time (min.) is displayed on the time indicator, and it will be
counted down according to process.
When operation is finished, the TIME INDICATOR will light up .

5. DIRECTIONS FOR DISASSEMBLY AND ADJUSTMENT
9
DIRECTIONS
BEFORE ATTEMPTING TO SERVICE OR ADJUST ANY PART OF THE WASHING MACHINE, DISCONNECT
THE POWER CORD FROM THE ELECTRIC OUTLET.
Warning
1) GENERAL ATTENTION
2)POINTS OF ATTENTION IN USAGE OF ELECTRIC COMPONENTS
Take care of the screws in order to use them in installation.
In case that the power is on, the earthing circuit of the computer sequencer can have a high voltage to earth.
Take care not to get electric shock.
Store the computer sequencer at shading and dry places. Avoid direct sunlight.
KEY POINTS IN DISASSEMBLY
Be sure to pull off the power plug in disassembly or maintenance.
Use stipulated crimp terminals in connecting the wires between the conducting wires as far as possible, and
fix with suitable tools, and insulate with insulation tape completely.
In inserting the conducting wires, be sure to plug the pins to the root and make it hard to be pulled out.
If welding is needed, be careful not to touch the plastic or other insulation parts with the iron.
When connecting the wires, be sure not to make the wire touch the mobile parts like the belt, radiating pulley
and jib etc., and the sharp protruding parts and the parts with high temperature (motor).Connect and fix the
wires as per their original mode.
If there's metal object at the wire fixing point, be sure to insulate with insulation materials.
METHOD OF DISASSEMBLING THE CONTROL PANEL
1. Open the back cover. Loosen
the inner wiring.
2. Loosen the screws used to
install the control panel seat(rear
and side) .Lift the rear upwards.
Loosen the control panel seat from
the inlay of the cabinet. Then move
it forwards several times.
3.Turn the control panel seat
backwards to open it gently. Do not
open by force.
ATTENTION:
Do not lift the control panel seat by force, otherwise the safety switch control rod may get transformed, and the
jointer part of the connecting pipe of the water level sensor may be loosened, therefore influence the normal
operation of the microswitch and water level sensor.
After opening the control panel seat, hold it with one hand or lean it on supporter like the wall. Do not put it down.
POINTS OF ATTENTION IN ASSEMBLY
Fix the wiring in the control panel seat to its original position. Do not make it touch sharp corner and mobile position.
The space surrounding the computer sequencer is rather narrow. Please dispose it carefully and do not make the
transformer press the wires.
Confirm that the control panel seat is installed to proper position of the Cabinet.
