RECOMMENDED TO CLEAN WITH EZCal
TROUBLE SHOOTING
Switch off the appliance and
unplug it from the socket before
cleaning it. Clean the water tank
and the base regularly. Use water
only, no detergents.
For best results use EZCal custom
cleaning agent for AIR-O-SWISS
products to remove deposits from
the water base regularly. Do NOT
run the unit when using EZCal. This
can cause damage to the product
and voids the warranty.
What is EZCal?
EZCal from AIR-O-SWISS is an easy and safe
cleaning and descaling agent recommended for
all humidifiers. It cleans mineral build-up in the
water base.
There is a sample of EZCal included in the packaging of your humidifier!
Only use 1 packet for 32oz of water. Do not change the ratio. Thoroughly rinse the base with tap water and make
sure no EZCal residues remain in the base. Instructions for use are on the packet. Please note: EZCal from AIR-O-
SWISS is the only recommended cleaning and descaling solution. Do NOT use any other cleaning solutions since
it can damage the product. Any use of cleaning solutions apart from EZCal will void the warranty.
EZCal descaling agent is available at selected retail stores.

AbOUT THE UNIT
White dust is emitted from the unit
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 demineralization
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 cartridge.
Use of distilled water
• For best results with your ultrasonic humidifier use distilled
water and remove the demineralization cartridge.
The hygrometer on unit reads a different humidity
level than external hygrometer
• 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 and temperature are diffe-
rent in every corner of the room and may affect the humidity
level. The unit should not be placed near a heat vent or a
radiator as the heat will absorb all of the moisture.
Humidity level is not changing or does not reach the
desired humidity level
• 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 buildings
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 ca-
pable 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.
No mist / unit is not working / empty indicator
keeps flashing
• 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 demineralization 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 a tablespoon 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.
Unit is running intermittently
• How long has it been since the contents of the cartridge
were replaced? If 2-3 months have passed, it is time to
replace the contents of the cartridge. However the demine-
ralization 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 contents of the cartridge were just replaced there are
probably too many granules in the cartridge. Remove a
tablespoon of granules from the cartridge.
ACCESSORIES
Do I need to keep any parts before I replace the
demineralization cartridge?
• Yes, always keep the water tank cap (this is the piece that
attaches the demineralization cartridge to the water tank).
What is the Ionic Silver Stick (ISS) and how long is
it good for?
• The ISS is effective in preventing the growth of bacteria and
molds in standing water. It needs to be replaced once a
year. The ISS can be used in all AIR-O-SWISS products plus
in all other humidifier brands.
Placement of the Ionic Silver Stick
• The ISS is effective in preventing microbial growth in stan-
ding water. Please see the quick set up guide for more
instructions.
Replacement reminder
• In each ISS box and on all the new products there is an
ISS lifecycle indicator. Check the box of the month when
starting to use the ISS and write the year on the line in-
dicated. Exchange it after 12 months.
Do not submerge base in water!
Thoroughly rinse the base with tap
water and make sure no EZCal
residues remain in the base!
