Instead of separat 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.
Note!
If the cooker hood is not connected, the end cap must not be remove.
Tumble dryer must not be connected to the ventilation unit, but have its own duct to the open
air.
Duct should be kept covered during storage and installation.
Location of the exhaust grid / roof cowl must also meet current building conditions, as well as any
requirements of local building authorities.
All inlet and outlet of the unit must be connected to the piping.
