The antibacterial plate incorporated in the base unit water tank component is a special metallic plate that exhibits antibacterial effects through catalytic reaction with water.
The continued use of the antibacterial plate causes discoloration, but this does not affect the antibacterial performance of the unit, which can be used as is.
Remove contamination attached on the antibacterial plate when cleaning according to the procedure described in the instruction manual to ensure sufficient antibacterial performance.
To prevent the risk of deteriorating the antibacterial effectiveness of the plate, do not pour anything other than tap water in the water tank.
