uororesin.
* Water with a large content of minerals in it
such as mineral water or ionized water, is
more likely to cause a scale or white layer in
the hot water.
●

wet soft sponge. (See P.14)
●
If the “scale” still remains, clean
with citric acid. (See P.15)

If the unit is placed on surfaces such as a vinyl sheet, the odor may be carried over into the
water.
Hot water comes
