Shutdown
When finishing operation, the operation should be stopped in accordance
with the proper steps.
Incorrect operation of the unit during use for hand washing, showering, or
cleaning, etc., may result in burns due to malfunction, which causes the
temperature of the water to rise above the set temperature.
When the unit is shut down for a long period of time or there is a
possibility of freezing, make sure to completely discharge steam
condensate or water in the unit and its components such as the steam
piping, heat exchanger, etc.
After doing so, there is a risk of burns or injury during operation start-up, as fluid
may be discharged from piping.
Make sure that hot water is not being used at the intended location for use.
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 activates.
・
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. Confirm that the indicated value on the pressure gauge (No. 19) is at "0" and
that no residual steam pressure is applied to the unit.
3. Touch the STOP button.
The solenoid valve (No. 12) and the control valve
(No. 11) close. When the cooling circulation unit
(optional) is installed, the solenoid valve (Option:
No. 7) opens and the circulating pump (Option: No.
6) operates.
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.
5. Close the valve (not included in the unit) on the
water supply system to stop supplying water to the unit.
