Condensation coming from the ventilation unit must be properly drained away.
For this, the ventilation unit must be connected frost-free and airtight to the
internal sewer system. The connection for the ventilation unit is Ø 32mm.
The condensation drain of the ventilation unit may not be fastened with an
adhesive joint and it must remain possible to demount it. For this, mount the in-
cluded transition piece by screwing it to the condensation drain. The dry siphon,
whether or not in combination with the sanitary 90° bend, can now be mounted
to this transition piece. A siphon forms part of the drainage system and is
delivered standard with the ventilation unit.
The siphon is of the "dry siphon" type and may be mounted both horizontally
and vertically. If use is nevertheless made of a “standard siphon”, it is important
that when the condensation drain is connected to the siphon with a hose, the
end of the hose discharges at least 25mm below the water level. For a fixed
connection, we recommend an extra filling possibility near the siphon.
