Air-O-Swiss U650 Mode D'emploi page 19

placed at least 3 feet off the floor, the mist will have the
opportunity to evaporate before hitting the floor.
Q. Water does not go into the tank.
A. In order to fill the tank, it must be turned upside down.
The cartridge is placed on the water tank cap. Do not
pour water in the tube which is the mist outlet.
Q. White dust is emitted from the unit
A. White dust particles are minerals that are broken up in
tiny pieces by the ultrasonic process.
Solve the problem:
• Soak the demineralization cartridge in a bowl of water
for a minimum of 24 hours. If the cartridge is soaked
in the water tank, the water in the tank and the base
needs to be replaced before using the unit.
• Exchange the demineralization cartridge after 1-2
months when you use very hard water (for softer water
after 2-3 months). No matter how hard your water
is, exchange the cartridge at the very latest after 6
months.
• Don't use water from a pre-installed water softener,
or sodium instead of calcium will be emitted from the
unit. Use distilled water instead and remove the demi-
neralization cartridge.
• For very hard water areas use only distilled water and
remove the demineralization cartridge.
• Use Reverse-Osmosis water (R-O water) instead of
distilled water and remove the demineralization cart-
ridge.
• Cleaning light is illuminated (digital models)
Switch off the unit and unplug it. Empty the water in
the base. Rinse the base with hot/clean water. Do not
submerge the base! Visually inspect the base for dirt
or mineral build up. If soft water is used decalcifying
the unit every 4 weeks with ECal is suggested. If hard
water is used the unit should be decalcified every
2 weeks. Do not forget to reset the clean light after
resetting the unit.

Q. R eset cleaning light (digital models)
A. The cleaning light does not automatically reset. Hold
down the power button (button A in instruction manual)
until the light stops flashing. The light automatically
comes on approx. after 14 days of plugging in the unit.
Q. The hygrometer on unit reads a different humidity
level than external hygrometer.
A. Not all hygrometers are calibrated the same, and most
are off by +/- 5%. Plus the humidity level is not the
same in the whole room. The air circulation is different
in every corner of the room. The unit should not be
placed near a heating vent or a radiator as the heat will
absorb all of the moisture.
Q. H umidity level is not changing or does not reach
the desired humidity level.
A. If the water tank needs refilling more than once per
day, the unit is working properly and the climatic
condition in the room has an influence on the humidity.
Reasons for low humidity level:
• air circulation is very high (air is fully exchanged
several times per day – the humidifier needs to starts
its work from scratch)
• insulation of home (see air circulation)
• open space with high ceilings (not only the footage of
the room counts but also the height) – high-rise buil-
dings require more humidification.
• open windows – works similar to air circulation (if it is
very cold outside don't open the window more than
2 times per day for 3 minutes)
• big difference between outside temperature and inside
temperature – the colder the air the less moisture it
is capable to hold and the more the air is heated up
the lower is the percentage of relative humidity (=the
amount of water vapor in the air, compared to the
amount the air could hold if it was totally saturated)
• position of the unit - if it is placed close to a door,
window or air vent. This increases the air circulation.
Q. Tank is leaking
A. Check if there are any hairline cracks. Dropped units or
water tanks that are cracked will not be covered under
the warranty. Please contact the retailer the unit was
purchased from in case your unit arrives damaged.
Q. Placing the face in the mist
A. It is not recommended that anybody places their face
in the mist. It is an electrical product and should not be
played with.
Q. No mist / unit is not working / empty indicator
keeps flashing
A. Fill up the water tank. Check if water is flowing through
the demineralization cartridge (attached to the water
tank cap). If the water tank is full but there is only little
water in the base it indicates that the water is now
flowing through the demineralization cartridge.
• Wait for 15 minutes to allow the mist to come out of
the unit.
• If the unit is not working and the empty light is not
flashing you might have set the desired humidity too
low and the current humidity level in the room is
higher. That is why the unit switches off automatically.
• If the empty indicator keeps flashing and the tank is
full, the water is not flowing through the cartridge.
Exchange the cartridge or the granules in the cartridge
after 2-3 months, in areas with hard water exchange
the cartridge after 1 -2 months. However, the demi-
neralization cartridge and or the granules must be
exchanged at the latest after 6 months or the unit does
not reach its full performance anymore
• If the granules are new, see the following instructions:
• Make sure the cartridge and/or granules were soaked
for 24 hours, dry granules take even longer for water
to filter through the cartridge and into the base. Next,
please remove 2 tablespoons of granules from the
cartridge, and throw them away. When there are too
many granules in the cartridge it does not allow water
to flow from the tank to the base.
