6 month or 800-cycle maintenance
Do not use abrasive, strong detergents or disinfectants.
Use a small non-abrasive brush to clean the areas that are difficult to reach.
Cleaning the water tanks
Switch OFF the sterilizer and disconnect the mains cable.
Completely drain both tanks.
Leave the drain tube attached to one of the drain quick connectors.
Lift the cover of the tank to gain access to the tanks.
Tap with your fingers on the rubber membrane to remove any condensate.
Remove the rubber membrane; clean and dry it.
Clean the internal tank surfaces with a soft sponge and a mild detergent solution, then rinse and dry
them. Make sure the drain tube is connected to the tank you are cleaning (left tank – grey colored
connector; right tank – blue colored connector) to drain the detergent solution.
Only when both tanks are clean, remove the internal filters (see picture), clean the metal cartridges with
tap water and put them back into their position. Reposition the rubber membrane.
Close the cover and disconnect the drain tube.
When cleaning the tanks, be careful not to touch the water level sensors. If misplaced or
misaligned from their original position, the operation of the sterilizer could be impaired.
