Connection of water trap
It is important that the water trap complies with the measurements below. If the water trap is placed outside the climate screen, it
should be protected against frost.

ATTENTION
There is positive pressure in the condensate drain in the ventilation unit and it is therefore not necessary to install a wa-
ter trap with a ball. In some installations a water trap can still be beneficial, however, because it prevents potentially bad
smells from entering the unit if operation should stop.
