Connection Of Condensate Drain - Komfovent DOMEKT C8 Installation Manual

3.7. Connection of condensate drain

In Domekt CF units with counter-flow plate recuperator, condensate is formed due to the difference between indoor and
outdoor temperature, therefore, units of this type are equipped with condensate drip pans and drainage outlets. Due to the
negative air pressure in the air handling unit, the water cannot drain out of the condensate collection tray by itself, therefore, it
is necessary to connect a siphon or a siphon with a one-way valve to the drain pipe.
The drainage pipeline must be mounted with a slope, without any constrictions or loops, which might prevent water from
draining easily. If the drainage pipeline passes through the outdoors or unheated premises, it must be adequately insulated
or equipped with a drainage heating cable to prevent water freezing in winter. Any drainage system cannot be directly con-
nected to the wastewater system in order to prevent the transmission of odours and bacteria into the supply air. Condensate
from the drain of the air handling unit must be collected in a separate container or into the sewage grate without direct con-
tact: do not connect drain directly to sewer pipe and do not immerse it into water. The condensate collection point should
be easy to clean and disinfect.
