3.3. Duct system installation
The air in and out of the unit flows through the duct system. The duct system should be designed and selected to have
low airflow rates and low pressure differentials, ensuring more accurate airflow rates, lower energy consumption, lower
noise levels and longer life of the unit.
Outdoor vents must be installed as far apart as possible on different sides of the building to prevent the exhaust air from
returning to the air intakes. Try to install the air intake vents where the outdoor air is the cleanest: do not direct them towards
the street, car park or outdoor fireplace. We also recommend installing the air intake vent on the north or east side of the
building, where the heat of the sun in summer will not have a significant effect on the supply air temperature.
It is highly recommended to install unit connecting ducts of supply inlet and exhaust outlet with a minimum slope on the
outside of the premise, to avoid water flowing into the unit in case of rain or snow.

It is recommended to insulate the ducts in unheated rooms (attic, basement) to avoid heat loss. It is also recommended
to insulate the supply air ducts if the unit is used for room cooling.
Circular air ducts are fitted to the unit with self tapping screws. Different air flow duct positions are marked on the sticker
located on the AHU:
outdoor intake air
air supplied to the premises
air extracted from the premises
outdoor exhaust air
