① Replace the water in the tank every day with fresh tap water.
② Do not use anything other than tap water. Drawn water, mineral water, alkaline ionized water, well water and water from water purifiers can cause proliferation of bacteria.
③ Clean the unit at least once a week as a rough standard, according to the procedures described under “Maintenance” in the instruction manual. Use a cleaning solution prepared by dissolving neutral detergent in water to deal with stubborn stains. Do not use any detergent other than neutral detergent. The base unit may be scratched. Rinse the cleaning solution off thoroughly with tap water after washing, as insufficient rinsing can cause odor and malfunction.
