WATER QUALITY MAINTENANCE WITH IONIC SILVER STICK
Water Quality Maintenance
The Ionic Silver Stick® (ISS) keeps the water free of microbial
growth. The ISS uses the anti-microbial eect of silver to prevent
the growth of microbes in the water base. It begins to function
as soon as it comes into contact with water, even if the unit is
switched o. The Ionic Silver Stick should be changed every year.
Please read the manual or check our website www.airoswiss.net for further information.
DO NOT DISCARD! Save for future reference.
Lifecycle Indicator
Your appliance comes with a lifecycle indicator
for changing the Ionic Silver Stick
yourself when you put the ISS into operation,
please check the current month on the stamp
and write the current year on the line provided.

RECOMMENDED TO CLEAN WITH EZCal
11 12 13
What is EZCal?
EZCal from AIR-O-SWISS is an easy and safe
cleaning and descaling agent recommended for
all humidiers. It cleans mineral build-up in the
water base.
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.
Cleaning light is on
• Switch o 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 EZ Cal is suggested. If hard water is used the
unit should be decalcied every 2 weeks. Do not forget to
reset the cleaning light afterwards.
Reset cleaning light
• The cleaning light does not automatically reset. Hold down
the On/O Dial (button A in instruction manual) until the
light disappears. The light automatically comes on approx.
14 days after of plugging in the unit.
Use of distilled water
• For best results with your ultrasonic humidier use distilled
water and remove the demineralization cartridge.
The hygrometer on unit reads a dierent humidity
level than external hygrometer
• Not all hygrometers are calibrated the same, and most are
o by +/- 5%. Plus the humidity level is not the same in the
whole room. The air circulation and temperature are dierent in every corner of the room and may aect 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.
Switch o the appliance and
unplug it from the socket before
cleaning it. Clean the water tank
and the base regularly. Use water
only, no detergents.
There is a sample of EZCal included in the packaging of your humidier!
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 residue remains in the base. Instructions for use are on the packet. Please note: EZCal from AIR-OSWISS 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.
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.
Do not submerge base in water!
The cleaning indicator still appears
on the display after cleaning. To
reset hold down the On/O Dial
until the cleaning light disappears.
Thoroughly rinse the base with tap
water and make sure no EZCal
residue remains in the base!
EZCal descaling agent is available at selected retail stores
and online at www.airoswiss.net.
TROUBLESHOOTING
Humidity level is not changing or does not reach the
desired humidity level
• If the water tank needs relling more than once per day,
the unit is working properly and the climatic condition in the
room has an inuence on the humidity.
Reasons for low humidity level:
• air circulation is very high (air is fully exchanged several
times per day – the humidier 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 humidication.
• 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 dierence between outside temperature and inside
temperature – the colder the air the less moisture it is
capable of holding. The more the air is heated up the lower
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 ashing
• Fill up the water tank. Check to see if water is owing
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 owing
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 ashing
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 o automatically.
• If the empty indicator keeps ashing and the tank is full, the
water is not owing 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
lter 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 ow 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 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 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 Ionic Silver Stick
bial growth. The ISS uses the anti-microbial eect of silver to
prevent the growth of microbes in the water base. It begins
to function as soon as it comes into contact with water, even
if the unit is switched o. The Ionic Silver Stick should be
changed every year.
Placement of the Ionic Silver Stick
• 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 indicated. Exchange it after one year.
