Cleaning the transducer/PTC heating element and water basin
Unplug the device.
During cleaning and descaling, the device must not be used.
Remove any splashes of Clean Air Optima® Cleaner & Descaler from work surfaces or the out-
side of the device with a soft, damp cloth.
1. Pour two capfuls of Clean Air Optima® Cleaner & Descaler into the water basin (one onto the
surface of the transducer and one onto the PTC heating element) and leave for between two
and five minutes.
2. Carefully remove the mineral (lime) layer from the surface of the transducer and PTC heater
with a small brush, cotton swab or toothbrush.
Caution: never use sharp or hard objects to clean the transducer/PTC heating element.
3. Then add water up to the rim of the water basin and leave for a minimum of 30 and a maxi-
mum of 60 minutes.
4. Rinse the transducer/PTC heating element and water basin thoroughly with water.
5. If there are still traces of limescale visible, we recommend that you repeat the cleaning and
descaling process.
6. Clean the inside of the water tank with a mild detergent and rinse with clean water.
After cleaning and descaling, your device is hygienically clean, free of limescale, free of bacteria,
free of viruses and immediately ready for use again.
Please note:
For cleaning and descaling, the device must be turned off/unplugged, so that no acid is re-
leased into the air via aerosols through ultrasonic misting.
