• Internal cleaning: You can clean the ultrasonic membrane with a con-
ventional household descaler. If there are lime deposits, we recom-
mend that you use Stadler Form Cleaner & Descaler (www.stadle-
rform.com/accessories). Alternatively, you can use a household
descaling agent or vinegar. Please do not try to scratch off deposits
from the membrane with a hard object. For stubborn deposits, we
recommend that you descale the device several times in a row. After the
descaling rinse the base and then dry thoroughly.
• No water may enter the air outlet opening (9). This will damage the appli-
ance and will void any claim to the warranty.
