(1) Close the steam inlet valve (No. 9) slowly.
When the STOP button is touched on the
touch panel without closing the steam inlet
valve, the following conditions may be caused
by the steam flow suddenly stopping:
・
The steam source pressure temporarily rises
and the safety valve (relief valve) (not
included with the unit) installed on the pipe
before the steam inlet valve opens.
・
Supply pressure to other steam-using equipment becomes unstable.
If there are no such conditions likely to occur, touch the STOP button to
stop operation. (Continue to Step 3.)
(2) Make sure that the indicated value of the pressure gauge (No. 19)
becomes "0" and steam residual pressure is not applied to the unit.

The motorized valve (No. 12) and the control
valve (No. 11) close. the solenoid valve (No.

At this time, "
STOPPING…" is displayed on
the touch panel.
(The time required for operation to stop is
approx. 30 seconds.)
(4) When the process to stop operation is
complete, the unit
’s internal systems have
fully stopped.
Make sure that "STOP" is displayed on the
touch panel and all components in the unit
(except touch panel and sensors) have
stopped.
