Duct system
It is recommended that the duct system should be made of
spiral-folded pipes assembled with fittings with rubber ring
seals so that you get a tight and durable duct system. To
achieve a satisfactorily low noise level from the unit, sound
locks must always be installed on the supply air and ex-
haust air duct system between the unit and the first supply
air and exhaust air fittings.
It is recommended that the air flows in the ducts should be
dimensioned at a sufficiently low level to ensure that noise
from the supply air and exhaust air fittings does not occur.
When positioning outdoor air and exhaust air hoods/
gratings, it must be ensured that the two air flows do not
short-circuit, thereby preventing the exhaust air from being
sucked in again. It is recommended that grates should be
placed on the north or east side of the house to achieve
optimal comfort in homes/flats.
It is recommended that the air intake should be located on
the north or east side of the house to achieve maximum
comfort and minimal impact from the sun’s heat.
Recommended minimum horizontal distance between air
intake and exhaust: 3 metres.
Recommended minimum vertical distance between air
intake and exhaust: 1 metre.
In order to connect ordinary galvanised steel ducts to the
ECO 360 R ventilation unit, you must first install 4 nipple
connectors in the unit’s Ø160 mm openings (double sealing
lips). Alternatively, Ø200 mm galvanised steel ducts should
be placed over the EPP connectors.
The unit is now ready for direct connection of ductwork on
the nipple connector. It is recommended installing galva-
nised angle brackets to fasten the nipple connector to the
galvanised housing using self-tapping steel screws.
