HOW TO CLEAN THE LINT FILTER
1) Pull the filter frame upward.
2) Turn the lint filter inside out, and wash the lint off with water
3) Return the filter as it was, and fix the filter frame to the slot.

Then the solenoid pull the locking lever which had lock the push button. Therefore the power is turned off
automatically.

DRAIN MOTOR
STRUCTURE
FUNCTIONAL PRINCIPLE
1) When the DRAIN MOTOR connected to the power source (A.C 220V), the DRAIN MOTOR rotates with
900 r.p.m and revolves the pulley by gear assembley for reducing.
2) When the pulley is rotated, the pulley winds the wire to open the drain valve.
3) Therefore rotation of pulley changes to the linear moving of wire.
4) The wire pulls the brake lever of Gear Mechanism Ass'y within 5 seconds.
5) After the wire pulled, gear assembly is separated from motor and condition of pulling is held by operation
of the lever.
6) When the power is turned off, the drain valve is closed because the wire returns to original position.
