Possible solution
• Make sure that there is power supply to the humidifier.
• Make sure that the water tank is filled with water and the upper
unit is placed properly onto the water tank.
• Make sure that the water tank is filled with water and the upper
unit is placed properly onto the water tank.
• Your room might have too much ventilation. Please close doors
and windows.
• Your room size is too big. The recommended room size is 25m²
for HU4801.
• Make sure that the humidifier is not overfilled with water.
• Make sure that the humidifier is well assembled/connected every
time after you clean it or after you remove the upper unit and/or
water tank for refilling.
• Make sure that the water tank is properly placed. If the problem
persists, contact the Consumer Care Center in your country.
The white deposits are called scale and they consist of minerals from
the water. Scale on the humidification filter affects the humidifying
performance, however it does not harm your health. Please follow
the cleaning instructions in the user manual.
The yellow deposits is a natural effect of the wick material, and it has
no impact on humidification performance. Clean the humidification
filter frequently to remove the scale, and replace the humidification
filter every three month.
Make sure that the water tank is filled with water. Clean the
humidification filter (see the chapter 'Clean the humidification filter').
Plug the humidifier into the power socket and switch on.
When mist is very fine, it is invisible. This humidifier has a specially
designed humidification filter that produces very fine mist. Therefore,
you cannot see the mist.
