PULSATOR SYSTEM
When the new shaped pulsator is rotated C.W or C.C.W at a high speed, it makes the 'heart-shaped' water currents as
shown below.
AUTOMATIC DRAINING TIME ADJUSTMENT
This system adjusts the draining time automatically according to the draining condition.
FUNCTIONAL PRINCIPLE
1. The micom can remember the time from the beginning of drain to reset point when the pressure switch reaches to
"OFF" point.
2. In case of continuous draining, residual drain time is determined by micom.
Draining time as a whole=D + 60
(T sec.)
WATER CURRENTS
A Water is pushed up near the tub
wall by rotation of the pulsator.
B Water is pulled down in the middle
of the tub by rotation of the
pulsator
C Water currents is generated by
rotation of the pulsator.
