d) Do not clean with chemical products.
2. Clean the inside of the water tank at least once a week, as follows:
a) Fill the tank with clean water adding a few drops of bleach or a simi-
lar disinfectant. Close the tank completely with its cap and shake
forcibly.
b) Rinse thoroughly.
Note: Water accumulated over long periods may create bacteria and
mildew (fungus).
3. Clean all the humidifier parts and then dry them well before storing the
apparatus in its box.
4. With each change of water the use is recommended of the brush in-
cluded, to remove dust and any lime remains on the transducer.
5. Do not place the transducer directly under the tap.
Water must not get into the apparatus; should that happen, take it to an
authorised assistance centre before using it again.
TROUBLESHOOTING
Do not try to open the apparatus: there is a risk of electrocution.
If it does not work:
• Ensure it is properly plugged in.
• Check that the switch is in the ON position.
If the operating light signal is on but, instead or vapour, the apparatus emits air:
• Check that there is water in the tank.
• Check for possible lime deposits on the water level float or the transducer.
• Check that the flow regulator is open.
Strange odour:
• Clean the tank with water and vinegar and rinse with clean water.
• Leave the tank open for some time without the cap, in a cool place.
OBSERVATIONS
• Ultrasound humidifiers produce smaller water particles which may more
easily reach the lower respiratory tracts. This type of humidifier is therefore
suitable for the treatment of symptoms of the common cold and laryngitis.
There use is not however recommended for persons with bronchial asth-
ma and allergies.
• Domestic humidifiers are ideal for obtaining a comfortable humidity envi-
ronment between 40% and 60%, the range in which the risk of respiratory
infection is minimised.
