If the power cord is damaged, it must be replaced by the manufacturer or a repair shop authorized by the manufacturer or by similarly qualified persons in order to avoid a hazard.
Prior to any maintenance, cleaning and after each use, switch off the appliance and unplug the mains cable from the socket.
Prior to cleaning the interior of the appliance, make sure the appliance has been off for at least 15 minutes!
Make sure that the appliance is placed on a surface that is not sensitive to moisture (avoid parquet flooring or delicate carpets). Moisture may form in the immediate vicinity of the humidifier.

Before setup: Anticalc cartridge and water hardness
The anti-calc cartridge reduces the limescale in the water and the undesirable emission of limescale particles into the surroundings. Effective for one to three months, depending on water hardness (see table).

Important : Soak the anti-calc cartridge in a water bath for 24 hours before the first use (not in the water tank!). The resin has to absorb water to reach high performance.

The period of time that the cartridge is effective for depends on the hardness of the water. This can be tested using the testing strip provided (see page 6).

Dip the testing strips into the water for a second.
After around one minute the results can be seen on the test strip.

Some of the green fields change color into pink. The water hardness is shown by how many boxes turn pink. Example: If three are pink, then the water hardness is >14 °dH.

With a water hardness above 21 °dH, we can no longer recommend the use of an ultrasonic humidifier. We recommend that you use an evaporative humidifier to increase the humidity in your house (e.g. an Oskar humidifier made by Stadler Form: www.stadlerform.com/Oskar)..)

Note: Do not operate Eva little with decalcified water out of a decalcification system that uses the principle of an ion exchanger (salt is added to the water). The salt contained in the water may lead to white dust accumulation around the appliance. To minimize this risk, you can operate Eva using a mix of distilled and tap water.

However, Eva Little may be operated from a drinking water filter system (e.g. Brita). Should you be unsure about the quality or composition of the water in your area, contact the caretaker or your drinking water provider.

Setting up

Setting up / operation

Put Eva little in the desired location on a flat surface. Connect the power adapter
to the unit and plug the adapter into a suitable plug socket. 2. Remove the water tank
by holding it by the handle and pulling it up. Screw off the water tank lid
and fill the water tank with clean, cold tap water up to the maximum mark. Make sure that the anticalc cartridge
has been soaked in water for 24 hours prior (see «Before setup»). Finally, screw the lid (3) back on the water tank (2). Then place the water tank
(2) in the unit. The water tray (5) will now slowly fill from the water tank. Important: please do not move the appliance when it is filled with water. The water could run into the electronics.
Press the on/off button (6) to switch Eva little on. The current relative humidity in % is shown on the display (10). If the water level indicator light (11) is red, there is too little water in the unit. The humidification output level is pre-set to level 3 and the desired humidity at 45 %.
The desired humidity can be changed by pressing the hygrostat button (7) several times (30 – 75 % and continuous operation «CO»). The symbol on the display (10) blinks during input. After a few seconds without input, the selected value is saved. The symbol changes to the current measured humidity.
Info: Once the desired air humidity is reached, the appliance stops and the display blinks. Should the measured current air humidity fall below the set value, the appliance begins to humidify again.
The humidification performance can be changed by pressing the button for the selection of the humidification output level (8) several times (levels 1 – 5). The level is indicated on the display (10) by horizontal bars (e.g. 1 bar = level 1).
By pressing the auto button (9), the auto mode, and with it the Adaptive HumidityTM Technology, is activated. Now the LED on the auto button on the unit is on. In auto mode, the unit adapts the humidification output level automatically in order to reach and maintain the desired humidity of 45 % quietly and in an energy-efficient way. The lower the current humidity is, the higher the humidification output level will automatically be set (under 33 % = level 4, from 34 % – 37 % = level 3, from 38 % – 41 % = level 2, from 42 % – 45 % = level 1). You can change the desired humidity in auto mode by pressing the hygrostat button (7) several times while auto mode is active (the LED on the auto button on the unit is on). The humidification output level (8) cannot be altered manually in auto mode. As soon as the button for the output level (8) is pressed to change the humidification output level, the auto mode is deactivated.
You can use Eva little to disperse fragrances in the room. Be extremely sparing with fragrances because an excessive dosage can result in the malfunctioning of, and damage to, the appliance. In order to use fragrances, briefly press and release the fragrance container (13) and pull it out of the appliance. Let the fragrance drip directly onto the cotton pad in the fragrance container. Add a maximum of 1–2 drops of fragrance into the fragrance container! Push the container back again and press and release it to lock it.
Tip : in order to change the fragrance, remove the cotton pad and clean the container with soap. Now you may insert a new cotton pad (commercially available) and add drops of the desired fragrance.
If the water level indicator (11) changes to red, the water must be refilled. Remove the water tank (2) and fill it with clean, cold tap water up to the maximum mark. Replace the water tank and press the on/off button (6). The appliance will resume operation after a few seconds. The water tank can also be refilled during operation.
If you find the lamps too bright (in a bedroom, for example), you may reduce the light intensity by pressing the night mode key (14):
- Normal mode (default mode)
- Dimmed mode (push once)
- Lights-out mode (push twice)
- By pushing the dimmer button once more, you can go back into normal mode.

If there is no water in the appliance, the red water level symbol (11) lights up in all modes. The red light cannot be dimmed.

Note : Should you see droplets (or other signs of dampness) on or around the unit, this condensed water is from the humidifier. This means that the air can no longer absorb the moisture from the humidifier. Please activate the auto mode with a desired humidity of 45 %. Water droplets should then stop forming.

Cleaning

Cleaning
Before each piece of maintenance and after every use, turn off the unit and remove the plug from the plug socket. Before you clean Eva little, the power adapter (1) must be separated from the power adapter connection.

Attention : Never submerge the appliance in water (danger of short- circuit). For hygienic reasons and to ensure proper operation, we recommend the following cleaning intervals.

Daily : Fill the water tank (2) with fresh, cold tap water. If the appliance is not used for several days, empty the water from the water tray (5) beforehand and if necessary, clean it with a bit of dish detergent and a clean cloth. Fill fresh water into the water tank (2), before putting the appliance back into operation.
Every 2 weeks: First remove the water tank (2), the mist chamber (15) and the Water Cube™ (16). Clean the inside of the water tray (9) thoroughly with a bit of dish detergent, warm water and a soft, clean cloth, sponge or brush. Use diluted descaling agent (mix according to the manufacturer’s instructions) for lime deposits. Then rinse the water tray (5) thoroughly with cold water and put the water tank, mist chamber (23) the Water Cube back in.
Descaling at least 1x per month. The appliance must be off for at least 15 minutes prior to internal cleaning! Then remove the water tank (2), the mist chamber (15), the Water Cube (16) and the fragrance container (13). Fill a cup with 200 ml of tap water mixed with descaling agent (mix according to the manufacturer’s instructions). Pour the liquid carefully into the water tray (5) by holding the cup directly over the water tray (see page 5). Do not pour the liquid into the water tray from high above the tray! Be sure that no liquid enters the air outlet opening (18). This will damage the appliance and will void any claim to the warranty.
Let the descaling agent allow to take effect according to manufacturer’s instructions (approx. 30 min.). Check in the water tray (5) if the limescale on the ultrasonic membrane (12) has dissolved. • If limescale residue remains, the ultrasonic membrane (12) can be cleaned with the help of the cleaning brush (17) (front- and backside). Do not try to scrape them with a hard object.
For stubborn limescale, we recommend descaling the appliance several times in a row.
Important: Pour the descaling agent out over the left front corner of the appliance (see the arrow on the appliance). No water may enter the air outlet opening (18). This will damage the appliance and will void any claim to the warranty.
To rinse, now fill the cup with 200 ml of tap water and carefully pour the liquid into the water tray (5) by holding the cup directly over the water tray (see page 5). Do not pour the liquid into the water tray from high above the tray! Pour the water out over the left front corner of the appliance. Repeat the process until there is no more descaling agent in the water tray (5). Place the Water Cube (16), mist chamber (15), water tank (2) and fragrance container (13) back into the appliance. If the water tank is not sitting right, check if the upper part of the mist chamber (15) is properly mounted.
Regularly as required : For external cleaning, rub with a damp cloth and then dry thoroughly.
At the end of the season: Before putting away the appliance at the end of the season, decalcify as described above. Then clean it thoroughly inside and out and let it dry completely. Insert a new Water Cube (16) in order for your appliance to be ready for the start of the next season.

Replacement of the anticalc cartridge

Please find the recommended replacement interval in the table (see «Before setup»).
Tip: the efficiency of the cartridge (4) can be inspected with a simple test. Hold a small mirror in the mist (19) for a few seconds. If white deposits (calcium carbonate) appear on the mirror, then the cartridge needs changing.
The anticalc cartridge is located on the inner side of the tank lid (3). First, screw the tank lid (3) off the water tank (2) and then screw the cartridge off the tank lid. Dispose of the cartridge in the domestic waste (4). Prior to screwing the new anticalc cartridge into the inside of the tank lid, soak it in water (not in the water tank!) for 24 hours.
Keep the tank lid (3) when replacing the cartridge!
