1 INTRODUCTION
The ventilation unit ensures a healthy indoor climate through continuous
ventilation. For this purpose, a minimum ventilation flow rate is always required.
The unit is therefore not equipped with an on/off switch. The resident must
ensure that the unit is always plugged into the wall socket and that the wall
socket is live.
The D ventilation system from Vasco Ventilation Concepts is a balance
ventilation system with heat recovery that guarantees a comfortable and
healthy indoor climate in a controlled way.
2 SAFETY

08 MOUNTING VENTILATION UNIT/ CONDENSATE
DRAIN
The ventilation unit must be mounted on a wall of sufficient strength. Wall
plugs and screws are not supplied. Use the appropriate fixing materials
depending on the wall structure.
The condensate from the ventilation unit must be discharged in a
proper manner. For this purpose, the ventilation unit must be
connected to the indoor sewage system in a frost-free and airtight
manner.
A siphon is part of this drainage system and must be provided on site
separately. We advise to glue the connection to the ventilation unit or
to connect it airtight by using a seal. The connection to the ventilation
unit is Ø32mm. If the condensate drain is connected to the siphon with
a hose, it is important that the end of the hose is at least
60 mm below the water level. For a fixed connection, we
recommend an additional filling possibility near the siphon.
