Setting up / operation
Please note: never transport the device with a full water tank. Possible hazards:
- Too much water from water tank comes into the main mase (6), this over loaded water level will cause dramatic reduction
of mist output of the device.
- Water can easily come out from the main base (6).
- The water tank can fall off from the main base (6) and get damaged due to the heavy weight from the water (and water
can leak on to the floor).
1. For this reason, main base (6) of the Hera humidifier should be placed first with empty water tank (3) in a suitable
location.
2. When the device is in the desired location: Fill water tank (3) with fresh water and screw the tank cover (5) back
on firmly and check that it is sealed properly. Place water tank on base. Plug power cable (1) into the power socket.
In the model with anticalc cartridge (4): do not take off the anticalc cartridge from the tank cover when opening and
filling water for the tank.
3. Switch on the device by pressing the On/Off button(11) on the control panel (7), the control display appears blue. The
mist cap (2) can be turned 360° or used bi-directional to have an even distribution of moisture.
4. The desired air humidity level can be selected by pressing the humidity button (12) on the control panal. The device
will be shut off automatically when the room humidity reaches the given level. On the display panel (7), it shows the
current humidity level in the room. By pressing the humidity button (12), you will be able to set the desired humidity
from 30 %, 35 %, 40 %, 45 %, 50 %, 60 %, 70 % and continuous mode. Release the button at your desired humidity
level or at continuous model, the unit is set and the display will switch to show the actual room humidity level again.
Note: on continuous the unit will NOT turn off automatically.
Caution: the device will not be switched on if the humidity level is set too low.
5. Pressing the output button (13) on the control panel, you can change the volume of output mist from level 1 to level 3
(shown on the display panel).
6. Warm mist button (14): the pre-heating can be switched on by pressing this button. This pre-heating will heat up the
water to 176 F° / 80 C° before it enters into the mist generation chamber. By this pre-heating function, the temperature
of the output mist will reach 104 F° / 40 C°, which will not cause the room temperature to drop when mist evaporates.
An orange LED light on the top of the display panel will be switched on when this pre-heating function is turned on.
Press this button again to switch off this function, and the LED light will be switched off.
7. Night mode button (15): by pressing this button, the device is switched to night mode with dimmed LED light on the
display. Default setting of desired humidity in this mode is: 50 %, and the ventilator works at level 1 as default. You
can change these settings by pressing the humidity button and output button. And the LED lights remain dimmed in
this mode. To cancel this mode, you can press the night mode button again.
8. Auto mode button (16): by pressing this button, the humidity level is set at 50 % automatically. The ventilator adjusts
the levels automatically according to the current room humidity:
Room humidity (%) Speed level of ventilator
< 35 % 3
36 – 45 % 2
> 45 % 1
By pressing this button again, the auto mode is deactivated. The humidity and ventilator speed settings are switched
to the previous settings, before auto mode was activated.
9. ”No water” alarm light: at the lower part of the display panel, there is red LED alarm light. This light will be switched
on when there is no water or not enough water in the mist generating chamber. When this light is on, you should
switch off the unit buy pressing the On/Off button and refill the water tank with fresh water, put it back onto the unit
and switch on the unit again.
Note: turn off the unit before taking off the tank. You need to turn on the unit again when placing the tank back on the
unit.
The unit shuts off its motor and its transducer automatically when water runs out. The “No water” LED light turns on.
In order to avoid unexpected damages, we recommend you to switch off the unit by pressing the On/Off button as
soon as the “No water“ light is on.
Cleaning
• Switch off the device and unplug the power cable from the socket before all maintenance work and after each use.
• Never submerge the device in water (this can result in short-circuiting). To clean the device, simply wipe it with a damp
cloth and then dry it thoroughly. Always ensure the power cable has been unplugged beforehand.
• Descale the humidifier as appropriate for the hardness of the water, but at least once a week: First remove the water tank
(the upper section) and clean it with a brush. Descale the device with a standard descaler and then rinse it thoroughly.
Reassemble the device completely before use.
• Thoroughly rinse out the water tank on a regular basis.
• Replace anticalc cartridge (4) every 1-2 months as appropriate for the hardness of the water.
Anticalc cartridge and water hardness
• The life-span of the cartridge is dependent on the hardness of the water. This can be tested using the test strip supplied
(The test strip is adhered to the reverse side of this instruction manual).
• Dip the test strip into the water for one second.
• After approx. one minute, the result can be seen on the measuring strip. Some of the green areas will change their colour
to pink. The number of pink areas corresponds to the hardness of the water.
• Example: If there are three pink areas, the water has a hardness of > 14°dH.
Number of Water hardness Degree of Cartridge will last for
pink boxes hardness (with 2 gallons / day):
(°dH) Days gallon
0/1 Soft from 4°dH 58 around 115
2 Moderately hard from 7°dH 30 around 60
3 Hard from 14°dH 20 around 40
4 Very hard from 21°dH 10 around 20
A simple test can be carried out to determine whether the cartridge is functioning correctly: hold a small mirror in the mist
coming out from the unit for a few seconds. If a white deposit has been left on the mirror (a sign of lime-scale), the cartridge
needs to be replaced.
Ionic Silver Cube (ISC™) (optional)
Before attaching the water tank, insert the Silver Cube in the base in the position indicated. The ISC™ with its patented technology prevents the growth of bacteria and germs. It can be used for a maximum of one season, and must be replaced at the
start of the next heating season (i.e. when the weather becomes cold). Despite using the Ionic Silver Cube (ISC™) you should
replace the water on a daily basis.
