Where are the air intake and exhaust grills located on the ATIKA ALE 300 N dehumidifier for optimal placement?
Frequently Asked Questions - 30/04/2026
Response Notice-Facile

The ATIKA ALE 300 N dehumidifier operates on the principle of condensation: the humid ambient air is drawn in through an intake grill equipped with an air filter, passes over the refrigerant element where the moisture condenses, and then the dried and slightly warmed air (about 2 to 5 °C above the ambient temperature) is expelled through an exhaust grill. To precisely identify these grills, refer to your user manual or look for the side or front openings of the casing, usually marked by the direction of the airflow.

For optimal placement of the ATIKA ALE 300 N dehumidifier, it is preferable to install it in the middle of the room to ensure good air circulation throughout the space. If this is not possible, position the device to ensure that the air intake and blowing are unobstructed. Maintain a minimum distance of 10 cm from walls and furniture, especially in front of the intake grill and behind the exhaust grill.

Follow these installation conditions to optimize performance: place the device on a horizontal surface to allow water to drain without obstacles, do not install it near a heat source (radiator, fireplace, etc.), and close the doors and windows of the room during use to prevent humid air infiltration from outside.

Avoid unsuitable locations: do not place the dehumidifier directly against a wall or furniture that would block the airflow, and keep it away from combustion sources. Never obstruct the air intake and exhaust openings with objects, fabrics, or any other impediments, as this would seriously compromise the dehumidification efficiency.

After assembling or transporting your ATIKA ALE 300 N, leave the device in an upright position for at least one hour before putting it into operation. This pause allows the refrigerant to settle properly in the circuit. Also, respect the operating range: only use it at an ambient temperature between 5 °C and 32 °C.

Function principle

This air dehumidifier works on the basis of the condensation principle.

Room air is sucked through a filter and a refrigerating element where water vapour in the air condense as water droplets. Then, the water droplets flow into a condensation water bowl

and further into the water container while the dried cold air is piped through the condenser of the device, heated and blown again into the room. The temperature of the blown out air is approx. 2-5 °C above the room temperature. This increase of heat is caused by power introduced in the compressor and fan and by heat which is released by the condensation of the water vapour.

The relative humidity of air is gradually reduced thanks to continuous recirculation of the room air through the device resulting in a quick and gentle drying of the room.

Water vapours move easily and unhindered through the air. Therefore, it is essential to "seal" the room as tight as possible. That means doors and windows must kept closed and entering and leaving the room should be restricted if possible. Otherwise the drying efficiency of the device is considerably impaired.

Assembly

After assembly, allow the device to stand vertically for at least one hour before powering it up. In this way, the refrigerant in it can settle.

Location of the air dehumidifier

Location

If possible, the air dehumidifier should be placed in the middle of the room in order to have a good air circulation in the whole room.

If this is not possible, locate the air dehumidifier so that air can be sucked and discharged unhindered.

Keep a minimum distance of 10 cm to walls.

Place the air dehumidifier

⇒ horizontally to ensure that the condensed water can flow off unhindered

away from a heat source (e.g. a radiator).

① Make sure that windows and doors of the room to be dehumidified are closed.

The dehumidifier must not be installed near burning sources, such as an open flame, a switched-on gas burner or electric heating with glowing spirals.

The device must be set up, operated and stored in a room with a floor space greater than “A min ”. (“A min ”: see “Technical data → min. room area”).

Electric supply

Compare the voltage listed on the device's type plate, e.g. 230 V / 50 Hz, with the mains voltage and connect the air dehumidifier to a suited and and properly earthed electrical socket.

Use an electrical socket with a rated voltage of 230 V with a fault-current circuit breaker (30 mA).

Power system fuse protection

10 A

Start-up

Before starting up

Did you transport the air dehumidifier in horizontal position or at an angle large than 45^ ?

i Allow the device to stand in vertical position for at least one hour.

Notes

  1. The air dehumidifier will not work if the set humidity value is higher than that of the environment.
  2. Only use the air dehumidifier at a room temperature between 5 °C and 32 °C. The air dehumidifier will not function out of this range.
  3. Do not operate the air dehumidifier in heavily dust-laden or chloric atmospheres.
  4. Once the compressor has been started the fan motor and the compressor must run for at least 3 minutes during dehumidification. To prevent damages to the compressor, you should wait for 3 minutes after a shut-down of the air dehumidifier before you restart the device.
  5. If the room temperature is under 10 °C and the relative humidity of the ambient air is rather low an operation of the air dehumidifier will not be necessary.
  6. The device's air dehumidification performance depends on room design, room temperature and relative humidity of the room air.
  7. Drain the container when it is full. Then, reinsert the empty water container so that the device can work again.
  8. Transport this device only in upright (vertical) position.
  9. If the device does not work or if the operation is suddenly interrupted for unknown reasons, see "Possible faults".
  10. When the air dehumidifier is in operation the compressor generates waste heat and the room temperature slightly increases. This is considered a normal process.

Fault code

If the fault codes E3 – E4 – E5 are indicated in the "RH display"

→ see "Possible faults".

Powering up

An acoustic signal will sound if you connect the power cable to an electrical socket.

A fault has occurred when this acoustic signal does not sound. Check the power supply cable, the electrical socket and the fuse.

Press the ON/OFF button to switch on the power to the air dehumidifier.

The display 2 ➔ "RH of air" indicates the factory-set humidity of air of 60 %. After 5 seconds the display indicates the actual humidity of air.

The “RH” display indicates the humidity of air in a range between 30 % and 90 %.

Shutting down

Press the button again to switch off the power to the air dehumidifier.

Setting the humidity value

Press the button (Increase the RH setting) or (Reduce the RH setting) to set your desired relative humidity of air.

If the set RH value is lower than 30 %, the device will continuously dehumidify and the indicator 2 displays "CO".

Hint: Normally, a relative humidity of air between 50 % and 60 % is sufficient to have a convenient indoor climate and to prevent condensation on structural components and furnishing.

If your desired RH value is lower than the actual RH by 3%, the air dehumidifier will automatically start (compressor). The 🔊 icon (dehumidification) is continuously displayed.

If your desired RH value exceeds the actual RH by 3 %, the air dehumidifier will automatically shut down (compressor). The ⬆ icon (dehumidification) is flashing.

Automatic defroster

At a room temperature under 20 °C not only condensation water is generated on the cold evaporator surface, but also ice. This ice blocks the heat exchanger so that the air flow is impeded. The built-in automatic defroster removes the ice from the evaporator. This allows a dehumidification operation down to a temperature of +5 °C.

During defrosting, the 🎨ion is displayed on the display, the compressor continues to run, the fan is automatically stopped. Once the defrosting process is finished the air dehumidifier returns to the dehumidification mode and the 🎨icon turns off.

Operating hour counter

The air dehumidifier is equipped with an operating hour counter.

The number of hours during which the device was in operation in the past is displayed after the dehumidifier is turned on. The amount of time during which the device remains on will be added to the already elapsed time.
