Solenoid valve for raw water supply
and
⑰
Solenoid valve for
boiler water supply
open simultaneously. Then water is supplied to
⑫
Boiler.
When

is energized to start distillation. At this moment,
③
Solenoid valve for cooling water
opens as well. The water supply to
⑫
Boiler
is regulated by opening
and closing
