16 CONDENSATE DRAIN/AIR DUCT CONNECTIONS
The condensation coming from the ventilation unit must be drained correctly.
For this purpose, the ventilation unit must be connected to the indoor
sewerage system in a frost-free and airtight manner. The connection to the
ventilation unit is Ø 32mm. In horizontal installation of the ventilation unit,
the condensation drain must be carried out with the sliding sleeve sup-
plied, fit it with lubricant on the condensation drain. In vertical mounting of
the ventilation unit, the sliding sleeve can also be used.
A siphon is part of the drainage system and comes standard with the
ventilation unit. The siphon is of the "dry siphon" type and may be mounted
horizontally or vertically.
However, if a "standard siphon" is used, it is important that when the
condensate drain is connected to the siphon with a hose, the end of the
hose extends at least 60mm below the water level. For a fixed connection,
we recommend an additional filling possibility near the siphon.
For a low-noise ventilation system, Vasco recommends using the parts
from the range offered for Vasco. Mount the installation with the lowest
possible air resistance and free of leakage.
The main air ducts should have at least the following internal diameter:
- DX4: Outside connection Ø170mm / Inside connection Ø180mm
- DX5/6: Outside connection Ø200mm / Inside connection Ø180mm
Home side connection
Vasco recommends using the Vasco Easyflow air duct system.
Exterior connection
The outside connection air ducts should always be insulated to prevent
condensation on the outside of the air duct.
