Servicing and Cleaning of the Water Tanks and its
components:
Monitor and clean regularly the dust filter in the water tank. The dust filter can be
carefully clean under flowing water. Afterwards leave the filter to dry prior to reinstalling
it into the water tank. We recommend a weekly cleaning of the dust filter.
The air humidifying filter should equally be monitored and cleaned weekly.
As such it can be dipped/inserted in cold clear water and carefully cleaned with a fine
paint brush or brush.
Afterwards re-insert the air humidifier filter back into the water tank.
The dust filter and air humidifying filter should be replaced every 6-12 months depending
on type and intensity of use.
To replace the filters first remove the water tank (as described under „Filling of water
tank“) and replace ultimately both filters. The cover to the water tank must be opened in
order to remove the humidifier filter.
After you have replaced the filters, fill the water tank with clean cold water and insert
back into the appliance.
