AUTOMATIC UNBALANCE ADJUSTMENT
This system is to prevent abnormal vibration during
FUNCTIONAL PRINCIPLE
1) While 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 is stopped and rinse process
i s started automatically
by P.C.B.
ASS'Y.
4) If the safety switch is operated due to
the unbalance of the tub, the program
i s stopped and the alarm is given.
CIRCULATING-WATER COURSE AND LINT FILTER
CIRCULATING-WATER
The washing and rinsing effects have been
i mproved by adopting the water system in
which water in the tub is circulated in a
designed pattern.
When the pulsator rotates during the wash-
i ng or rinsing process, the water below the
pulsator vanes creates a water currents as
shown in figure.
The water is then discharged from the up-
per part of the tub through the water channel.
About 40L/min. Water is circulated at the
' high' water level, standard wash load and
standard water currents.
LINT FILTER
Much lint may be obtained according to the
kind of clothes to be washed and some of
the lint may also sticks to the clothes.
To minimize this possiblity, a lint filter is
provided on the upper part of the tub to filter
the wash water as it is discharged from the
water channel. It is good to use the lint filter
during washing.
