Pulsator System

When the pulsator is rotated C.W or C.C.W at a high speed, it makes the cyclone water flow from the asymmetrically
designed pulsator as shown below.
Automatic Drainning time Adjustment
This system adjusts the draining time automatically according to the draining condition.
Good draining
Draining
Bad draining
condition
No draining
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
Drain Time Movement of the Program
Less than
Continue draining
15 minutes

Program stops and gives the alarm with
15 minutes
2 In case of continuous draining, residual drain time is determined by micom.
Draining time as a whole = D + 90
12 EXPLANATION
Asymmetrically designed pulsator
makes the cyclone water fow, which get
rid of the washing dead zone to
increase the washing effect and reduce
the entanglement of laundry.
The washer begins spin process after drainage.
Draininig time is prolonged.
Program is stopped and gives the alarm.
blinked on display lamp.
Residual drain time.
The time remembered by micom.

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 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 auto-
matically 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.
NOTES
The alarm finished when you close the lid after opening
it. Check the unbalance of the wash load and the instal-
lation condition.

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 pul-
sator 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.
