13.3. Connections
13.3.1 Connections of sensors / external functions
Plugs for connecting external sensors you find in the accessories bag supplied with the unit.
13.3.2 Duct connections
The unit is mounted preferably in for example laundry room, storage room, utility room, etc. Air duct
from cooker hood can be connected to separate "bypass channel" in the top of the unit, marked
“Cooker hood”.
The choice of placement must be taken into account that the unit requires periodic maintenance. Be
sure that it is possible to open / remove the unit inspection hatch, and that there is sufficient room to
remove the main components. If the unit is mounted on the lightweight wall construction to the living
room, for example bedroom / living room, recommended wall insulated / constructed so that the risk
of sound transmission avoided.
Fresh air intake is to be placed primarily on the building's north and east and at a good distance from
the exhaust openings for ventilation, central vacuum, Hoods and Vents, sewer vent, chimney or other
contaminated source such as dust / exhaust from traffic etc. The return of the exhaust air should
always be in good distance from fresh air intakes, close windows, etc

Instead of separate roof cowl for exhaust air and wall grid for fresh air there also can be used combi
grids with inlet and outlet air are in the same box.
Air to and from the unit will be led through the ducts. Best durability and capabilities for cleaning will
be achieved by using ducts in galvanized steel.
Short customizations (à 1 m length) with a flexible aluminum - ducts can be used for piping between
the unit and roof cowl / wall grid.
In order to achieve effective, low energy consumption and proper airflow, the duct system designed
with low air speeds and low pressure drop.
