Functions

The AD-series are combined units that will both clean and dehumidify the indoor air. The air purifying function is always active as long as the unit is running. Activate the dehumidification to remove excess moisture. When dehumidification is active the compressor starts and the icon is lit. When the set humidity level is reached, the icon is flashing.

Modes

The unit has 4 different modes; manual, automatic, quiet, or clothes dry mode (clothes dry mode is only available when dehumidifying).

Manual mode

Set fan speed manually. Choose between 4 fan speeds in dehumidification mode and 5 fan speeds in air purification mode. If dehumidification is activated, set desired humidity level manually.

Quiet mode

The unit works on the lowest fan speed. The air quality indicator is shut off.

Clothes dry mode

(dehumidification only). Use this function for the quickest drying of clothes and laundry. The unit will work on maximum fan speed continuously; humidity level and fan speed cannot be set.

Automatic mode

In air purification mode, the fan speed is set automatically depending on the air quality of the room. The air quality is indicated by the light on the front of the unit;

Green: no pollution detected. Fan works on speed 1.
Blue: light pollution detected. Fan works on speed 2.
Yellow: moderate pollution detected. Fan works on speed 3.
Purple: heavy pollution detected. Fan works on speed 4.
Red: very heavy pollution detected. Fan works on speed 5.

If dehumidification is activated the unit automatically sets fan speed according to ambient relative humidity:

60% RH or below: dehumidification stops, the fan runs on speed 1
60-65% RH: fan runs on speed 2
66-70% RH: fan runs on speed 3
71% RH or above: fan runs on speed 4

Set desired humidity level

When the set humidity level is reached the unit stops automatically. The set humidity level is shown for a few seconds in the display. CO means the unit will run continuously, regardless of ambient humidity.

Set timer for shut off

Set time for automatic shut-off between 1 and 12 hours. Press the timer button repeatedly until the timer display is blank to deactivate. After the set time has passed the unit is shut off. To restart it, you need to manually press the Power button.

Select fan speed

There are 4 fan speeds for dehumidification and 5 fan speeds for air purification. A higher fan speed means quicker air cleaning and dehumidification. During dehumidification, when the set humidity level is reached, both the compressor and the fan motor stop for 60 minutes. After 60 minutes, the fan will start and run for 3 minutes to sense the surrounding moisture level. If the humidity level has not increased, the machine will continue to stand still for 60 minutes and then start the fan for 3 minutes.

If it is higher than the set limit, both the compressor and motor will start again.

Child lock

Press and hold the child lock button for 3 seconds to activate or deactivate the child lock. When activated, all buttons are locked.

Active ION HEPA filter

The Swedish-made, patented Active ION HEPA filter ensures top-quality filtration, without blocking the airflow. This means that noise levels and energy consumption are kept as low as possible.

The Active ION HEPA filters need to be replaced regularly to maintain their high capacity, and to prevent damages to the unit. The unit also has a reminder alarm when you need to replace the filter.

Filter replacement (FIG C & D):

Filter replacement

Remove the filter cover on the back of the unit.
Remove and dispose of the expired Active ION HEPA filter.
Insert a new Active ION HEPA filter.
Remove any dust or dirt on the filter cover and put it back. The filter cover can be cleaned with warm water and a mild detergent, or with a vacuum cleaner.

Filter replacement reminder

After 970 hours of use, the unit controls the status of the Active ION HEPA filter. When controlling, all buttons are locked and the air quality light is flashing. The unit will repeat this test 4 times, with 10 hours intervals If the filter is too dirty, the replacement indicator is flashing. Replace the filter and press and hold the restet button for 5 seconds to deactivate the alarm. If the filter doesn’t need to be replaced, the unit will remind you to replace the filter after 1500 hours of use.

The filter must be replaced regularly, otherwise, the unit might lose capacity and even be seriously damaged.

Maintenance

Clean the unit with a soft moist cloth. Do not use solvents or strong cleaners as this might damage the surface of the unit.
The cooling coils are best cleaned with a rag and warm water.

Service

If the unit requires service, you must first contact your local retailer. Proof of purchase is required for all warranty claims.

Hints

Sometimes it may be useful to use a frost guard or heater fan to make sure that the temperature does not fall below +10˚C. Even if the AD-series can dehumidify down to temperatures as low as +5°C, their capacity will increase at higher temperatures as warm air carries more water.
For maximum capacity in a room, it is recommended that the air supply from outside and from adjoining rooms is minimized – close doors and ventilators.
Expect higher dehumidification capacity during Autumn / Summer because the outside air is warmer and more humid.
To achieve safe and reliable protection against mould and moisture damage, keep the relative humidity between 50% and 60%.
Use a higher fan speed for quicker dehumidification and air cleaning.
