Caution! Operating the blower when the humidifier is filled but the therapy tube is disconnected may cause water droplets to be swept along in the air flow. Therefore the therapy tube should always be firmly in place before switching on the humidifier.
CLEANING Please carefully follow the hygiene and cleaning instructions in order to preserve your health and to avoid disturbances and failures. Except from cleaning it regularly, the device requires no further maintenance. The regular, daily cleaning prevents the built-up of limescale which is difficult to remove.
Page 16
Empty the water reservoir and rinse it with running water. Remove any limescale by wiping it with a soft cloth. If tough limescale has built up we recommend using normal limescale remover or filling the water reservoir with a thin vinegar solution and let it soak for a while. Then empty the reservoir, wipe off any residue lime- scale with a soft cloth and then rinse the reservoir tho- rouhgly under running water.
