by the sensor.
CAUTION
The setting described

configured to activate
the pre-flush.
This product has the following automatic flushing functions.
< Interval discharge pipe flush >
In addition to flushing after every use, discharge pipe flushing is performed every 2 hours.
Discharge pipe flushing is performed efficiently using 2 flushes, reducing urine accumulation
and urolith adhesion inside the discharge pipe.
< Intermittent spray flush >
To prevent damage due to sudden winter cold in normally temperate regions, the ambient
temperature is detected and intermittent flushing is performed to minimize the risk of freezing.
< "ewater+" cleaning > * Super water saving type only
Time periods when the urinal is not used for a long time, such as at night, are judged
automatically and the trap is filled periodically with "ewater+". Because the occurrence of
dirt inside the trap is reduced, the flush volume after use can be reduced.
* "ewater+" is water created by electrolyzing chloride ions contained in tap water, and
includes sanitizing components (hypochlorous acid).
CAUTION
The above effects cannot be obtained while the power supply is off.
* In the AC type, water is flushed when the power supply recovers after a power outage.
This is normal.
