MINIMUM WINDOW OPENING
Before installation you should determine the minimum
opening of the monitored window which is based on:
a) The power of the exhaust air device in m³/h
b) The size of the window to be opened in m²
c) The size of the window opening in cm (see table 1)
Most kitchens have rectangular tilt and pivot windows.
If your window is round for example, please ask the
installation and heating engineers or electrician to calculate
the minimum opening.
The minimum opening of rectangular windows is shown as
an example in the table for the tilt and pivot position.
1. Determine the extraction power of your exhaust air
Calculation table to determine the minimum
opening of your window (Table 1)

extraction device unit in m³/h. You can find the exhaust
air extraction power on the identification plate or in the
operating instructions of your exhaust air device (e.g.
extractor hood).
2. Measure the inner width and height of the window and
calculate the window size in m².
(width x height = m²; e.g. 0.8 m x 1.0 m = 0.8 m²) =
window size
3. Using the table, work out the opening size (minimum
opening for your window) from the extraction power and
window size.
4. While the window is in the titled position, measure the
upper inner gap size of the window in cm. The gap size
of your window must not be below the opening size
calculated! The bigger the gap or window opening,
the better.
