MANU

AL

VENTILATION CONTROL

The house extraction fan serves as a mechanical air 

extraction unit in the apartment, allowing the resident to 

adjust the ventilation efficiency. The efficiency is adjusted 

using the ventilation efficiency control.

It is recommended that ventilation be left turned on during 

long holidays also. This keeps the indoor air fresh and 

prevents humidity from condensing in the ventilation ducts 

and structures. It also reduces the risk of moisture damage. 

USING THE UNIT

The house extraction fan has a sliding glass that can be 

pulled out of the cooker fan. It is recommended that the 

sliding glass be pushed or pulled from the aluminum strip on 

its front edge. Pull the glass out of the house extraction fan 

for maximal extraction capacity.

  Position of the damper 

In normal circumstances, the damper must be closed  

(the signal light is off), which boosts the extract air flow from 

other premises.

The damper must be open

 (the signal light turned on)  

when the user wants to increase the extract air flow  

from the house extraction fan, e.g.

•  when the cooker top or the oven is used for cooking;
•  the load in the kitchen is exceptional due to the use 

of strong detergents, presence of a large number of 

people, or similar.

Front panel buttons

The front panel of the house extraction fan has four buttons.

1.  Away profile

 

The ventilation efficiency can be temporarily 

reduced when the apartment is unoccupied. 

  House extract fan light

Turn the light on or off by pressing the light switch. The light 

is dimmable. Adjust the brightness by pressing the light 

switch until the brightness is adequate.

  Ventilation profiles

Select the profile by pressing the ventilation profile button 

repeatedly until the signal light indicates the desired 

ventilation profile.

  Away profile  

  At home profile   

  Boost profile

  Settings button

The settings button is roughly 2 cm to the left from the light 

switch.

Other functions

Guard function

The house extraction fan is equipped with a guard function 

that is activated when the temperature of the house 

extraction fan exceeds 60°C or after a sudden increase in 

temperature (> 8°C/min). In such a case, all signal lights of 

the house extraction fan and the LED light will flash. If this 

kind of an alarm is noticed before fire damage, it can be 

acknowledged by pressing any of the house extraction fan 

buttons.

Pre-setting of light brightness

To modify the pre-setting of light brightness:

1.  Turn on the light, close the damper, and set the 

ventilation to the Away profile.

2.  Press the settings button for roughly 3 seconds until the 

setting mode signal light starts to flash.

3.  Adjust the brightness of the light by pressing the light 

button until the brightness is adequate.

4.  To save the setting, press the settings button for roughly 

3 seconds until the setting mode signal light stops to 

flash.

2.  At home profile

 

Ventilation must be continuous, i.e. the air 

inside the building must be replaced at least 

once every two hours.

3.  Boost profile

 

Cooking, sauna, bathing, drying of clothes, 

excessive heat, and other similar situations 

can require that ventilation be increased 

from the standard setting. In such a situation, 

ventilation must be increased.

  

PLEASE NOTE!

•  Neglecting the cleaning of the grease filter can cause a 

fire hazard.

•  The outer surfaces of the house extraction fan can 

become hot when the cooker top or the oven is turned on.

•  Flaming is forbidden underneath the house extraction fan.
•  Always follow the instructions provided on adjusting the 

efficiency of ventilation.

•  Enable a sufficient supply air flow into the room if the 

house extraction fan and non-electric devices are used 

simultaneously.
