Stadler Form Eva Little Operating Instructions Manual page 11

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 decalcifica-
tion 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. The mixing ratio should be 50:50.
Attention: Please do not operate the unit using pure distilled water as the
water level indicator will not work correctly. However, Eva little may be op-
erated 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 care-
taker or your drinking water provider.
Setting up / operation
1. 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.
2. 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.
3. 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 %.
4. The desired humidity can be changed by pressing the hygrostat button
(7) several times (30 – 75 % and continuous operation «CO»). The sym-
bol 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.
5. The humidification performance can be changed by pressing the but-
ton 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).
6. By pressing the auto button (9), the auto mode, and with it the Adaptive
Humidity Technology, is activated. Now the LED on the auto button on
TM
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 humid-
