recommended by the manufacturer may cause fire, electric shock
or malfunctions.
Ensure that the mains voltage complies with that indicated on the
data plate (220-240V/50Hz).
This appliance can be used by children aged from 8 years and
above and people with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have been

Cleaning and user maintenance shall not be made by children
without supervision.
This product is not a toy. Children should be adequately
supervised to ensure they do not play with the appliance.
Disconnect the mains power when the appliance is not in use
or when performing cleaning operations. Keeping the
appliance plugged in may cause electric shocks or accidents.
To disconnect the appliance, set the switch to OFF and remove
the plug from the socket. Pull on the plug only. Do not pull on the
cord when turning off the appliance.
Do not insert any objects or needles in the mist discharge nozzle
or in the compartment next to the handle. This may cause electric
shock, malfunctions or other accidents.
Do not bend, drag or twist the cord, or apply force to remove it. Do
not operate the unit if its cable or plug are damaged; doing so
can cause fires or electric shocks. Contact a service centre to
replace a damaged power cord, so as to avoid any safety risks.
Do not use the appliance in the presence of other electric
equipment such as computers or precision instruments. The

12
V 10/16
humidity or “white dust” contained in the mist may cause the
appliances to malfunction.
In the event of an anomaly, switch the appliance off and unplug it
immediately. Do not dismantle, repair or modify this product freely.
In the event of a malfunction, contact the after-sales service centre
directly.
Do not immerse the power cord, plug or any other part of the
appliance in water or other liquids.
Do not touch the plug with wet hands.
Do not inhale the mist discharged from the nozzle.
Do not use acidic or basic solvents to clean the inside of this
appliance: the residue may affect the proper running of the
appliance.
Do not operate the appliance on unstable surfaces, as the water
flowing out of the appliance may wet the floor or cause
malfunctions. Do not place the appliance on a high or sloping
surface, as it may fall as a result of vibrations or accidental
knocks. Placing the appliance on a sloping surface may cause the
humidifier’s water level control device to malfunction, thereby
causing an interruption in operation or loss of water.
Do not expose the humidifier to direct sunlight and never place the
appliance on or near an air-conditioner: this could cause
deformation, discolouration or malfunction.
Do not place the appliance on furniture or stands with poor heat
resistance: this could cause deformation and discolouring of the
base due to overheating.
Do not place the appliance in places with a strong magnetic field:
this may cause malfunctions.
Do not place the appliance on blankets or carpets as these may
block the entry of air underneath the appliance and cause faults or
malfunctions.

13
V 10/16
Do not place the appliance close to furniture or curtains. The mist
may wet the furniture or curtains causing them to fade or deform.
Also, the white powder contained in the steam could alter the
furniture's surface: therefore you should avoid directing the steam
jet directly towards furniture.
Do not operate the appliance in close proximity to bathtubs,
showers, washbasins or pools.
WARNING
To move the appliance, lift the base without tilting the unit to
avoid water spillage.
To fill or empty the tank, hold the top of the unit on both sides
without the decorative part.
Do not open the appliance while it is running, do not make
contact with the water that collects at the bottom, do not
scratch the ceramic disc with hard objects.
The internal ultrasonic nebuliser is highly sensitive. Do not touch it
with fingers or rub it with metal accessories to avoid reducing mist
emission.
WARNING: An excessively damp environment can cause a
proliferation of micro-organisms: avoid letting curtains or
carpets absorb excessive moisture.
It is also recommended to remove any water left in the tank
after each use and to fill the water tank with fresh water every
day. Clean the water tank and nebuliser every 3 days and keep
them clean. Do not add any aromatic fragrances to the water in
the tank.
Do not connect the appliance to the mains supply if the water tank
is empty or if the appliance is upside-down: this will cause the
nebuliser to malfunction.
Do not move the appliance while it is operating; doing so can
cause leaks and malfunction.

14
V 10/16
During winter, the water in the tank may freeze and cause the
appliance to malfunction. Remove the water from the tank.
Carry out maintenance on the appliance by regularly and
thoroughly cleaning the tank and nebuliser. Continuous operation
of the appliance with dirt residues may lead to faults and
malfunctions.

Unplug the mains, lift the tank with both hands, turn it and fill it with clean water. Then reposition it, reconnect the mains
and hold down the middle button.
Use clean water every time the appliance is used in order to guarantee a longer life-span and increased effectiveness of
the humidifier.
The appliance will switch off automatically when the tank is removed or if there is a shortage of water.
If you wish to add fragrances to perfume the room, remove the lid of the fragrance compartment, pour in a few drops of
essential oil and close the compartment: do not add any fragrances directly to the water in the tank.
To avoid any interruption of operation due to a lack of water during night-time use, it is recommended to fill the tank at
least ¾.
WARNING!!
It is normal for water to collect on the bottom of the appliance: the water passes from the tank into the base of
the unit to trigger the ultrasonic humidification mechanism.
Be careful when removing the water tank for filling/emptying or cleaning operations, as the water accumulated
on the bottom may drip from the tank.
Dry the tank with a towel to avoid getting the floor or furniture wet.
WARNING!!
Always use the humidifier in a temperature between 5 °C and 40 °C.
The ideal room humidity is between 40 and 60. The respective humidity should be less than 80%.
Fill the water tank with tap water only, without adding any fragrances or essences.

INFORMATION ON THE CORRECT DISPOSAL OF THE PRODUCT, PURSUANT DIRECTIVE 2012/19/EU ON WASTE
ELECTRICAL AND ELECTRONIC EQUIPMENT"
At the end of its useful life, this appliance must not be disposed of together with household waste. We call your attention to the
crucial role played by the consumer in the reuse, recycling and other forms of recovery of such waste. The appliance must be
scrapped by a sorted waste disposal centre or by returning it to the retailer (no charge is levied for this service), when you
purchase a new equivalent appliance. Large retailers (a sales area of at least 400 m2) are required to provide a free take-back
service for very small EEE products (external dimensions not exceeding 25 cm) even if a new product is not purchased.
Sorted disposal of electric and electronic equipment prevents the negative effects on the environment and human health
resulting from improper scrapping, and also allows the materials from which it is made to be recovered and recycled, with
significant savings in terms of energy and resources. The sorted disposal requirement is indicated by the crossed waste bin
label displayed on the appliance.
