AIR-O-SWISS 2055A Leaflet

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. 

Do not submerge the main body in 

water! The cleaning indicator still ap-

pears on the display after cleaning. 

To reset hold down the two hygrostat 

buttons until the clean light stops 

flashing. Thoroughly rinse the base 

with tap water and make sure no 

EZCal residue remains in the base!

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 residue remains 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.

•  An exact answer cannot be given for this as there are many 

factors that depend on how long the water will last for. It 

all depends on the size of the room, if it is very dry, among 

other things to know how quickly water will evaporate into 

the air. If you notice that there is no water left in the water 

tank, it is always a good idea to refill the tank to have extra 

water available.

•  The red LED light on the appliance shows you when the unit 

should be refilled with water. If the water level falls below 

the minimum level, the appliance automatically switches off. 

The red LED appears on the display. When water is added, 

the red LED changes to green and the appliance continues 

operating. 

Please note: When lifting the upper part off the housing, the 

appliance also switches off. In this case, the red LED will 

also appear on the display. Only when the upper part is 

replaced on the base does the red LED (E) disappear and 

the appliance resumes operation.

•  Water is needed in the base of the unit for the removal of 

particles from the air, and for the humidification of the air. 

The first time the tank is filled up and placed on the unit, all 

of the water will go into the base of the unit. The water tank 

acts as a reserve, and may be filled up a second time to 

have extra water available.

•  The manufacturer of this appliance does NOT recommend 

it. The discs can only be placed in a dishwasher where  

the temperature is no greater than 131°F / 55 ºC. If the 

temperature is any hotter than this, the discs will melt. Place  

the plates in a sink filled with warm water and white vinegar 

or EZCal and either let them soak or spin the plates in this 

solution. Or, add white vinegar or EZCal to the water in the 

base of the unit and let the unit run for an hour to clean the 

plates. It is good to have calcium deposits built up on the 

plates as it will capture more particles from the air and add 

more moisture to the air.

  For troubleshooting, see chapter «Troubleshooting».

•  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 capa-

ble 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.

•  Yes, the unit can be used all year round. The unit produces 

relative humidity which means that the air will only take as 

much moisture as it can hold. The unit will not over-humidify 

the air.

ACCESSORIES

•  The Ionic Silver Stick

®

 (ISS) keeps the water free of micro- 

bial growth. The ISS uses the anti-microbial effect 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 off. The Ionic Silver Stick should be 

changed every year.

•  Please see the quick set up guide for more instructions.

•  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 one year.
