• This is harmless. Small bubbles appear as the air in the
water is heated and depressurized rapidly to
atmospheric pressure.
• Coloration to a blue color may be noticed from small
traces of copper ion contained in the water and fat
(furring). However, there are not problems concerning
health. Coloration of the bath tub/wash-basin can be
prevented by cleaning frequently.
• Condensation forms inside the unit during operation
and is discharged from the drain pipe.
