Before setup: Anticalc cartridge and water hardness

The anticalc 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 anticalc 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).

1. Dip the testing strips into the water for a second.
2. After around one minute the results can be seen on the test strip.
Some of the green fields change colour 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.

Number of pink boxes| Water hardness| Degree of hardness (°dH)| Cartridge will last for (with 3 liter/day)
---|---|---|---
Days| Liter
0/1| Soft| From 4 °dH| 120 days| approx. 360 L
2| Moderately hard| From 7 °dH| 60 days| approx. 180 L
3| Hard| From 14 °dH| 40 days| approx. 120 L
4| Very hard| From 21 °dH| 20 days| approx. 60 L

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. 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 / operation

Put Eva little in the desired location on a flat surface. Connect the power adapter (1) to the unit and plug the adapter into a suitable plug socket.
Remove the water tank (2) by holding it by the handle and pulling it up. Screw off the water tank lid (3) and fill the water tank with clean, cold tap water up to the maximum mark. Make sure that the anticalc cartridge (4) 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 (35 – 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. After replacing the water tank, the appliance automatically resumes 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

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 external cleaning, rub with a damp cloth and then dry thoroughly.
Clean 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 Silver 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 Silver 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.
Clean the water tank (2) thoroughly every two weeks with a soft brush or sponge and warm water. Use diluted descaling agent (mix according to the manufacturer’s instructions) for lime deposits. Rinse the water tank afterwards with clean, cold tap water thoroughly.

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!

Silver Cube™

The Silver CubeTM (16) prevents the growth of germs and bacteria in the humidifier due to the continuous release of silver ions. The use of silver cubes leads to a hygienic room climate. The lifetime of the silver is around one year. We therefore recommend that you replace the silver cube at the beginning of every humidifying season. The silver cube starts working as soon as it comes into contact with water, and also works when the unit is switched off.

Repairs

Repairs to electrical appliances must only be carried out by a qualified electrical technician. If improper repairs are carried out, the warranty lapses and all liability is refused.
Never operate the appliance if the adaptor or plug is damaged, after it has malfunctioned, if it has been dropped or has been damaged in any other way (cracks/breaks in the casing).
Do not push any object into the appliance.
If the appliance is beyond repair, make it unusable immediately by cutting through the cable and hand it in at the collection point provided for the purpose.

Disposal

The European directive 2012 / 19 / CE on Waste Electrical and Electronic Equipment (WEEE), requires that old household electrical appliances must not be disposed in the normal unsorted municipal waste stream. Old appliances must be collected separately in order to optimize the recovery and recycling of the materials they contain and reduce the impact on human health and the environment. The crossed out «wheeled bin» symbol on the product reminds you of your obligation, that when you dispose of the appliance it must be separately collected. Consumers should contact their local authority or retailer for information concerning the correct disposal of their old appliance.
