2.0 Assembly
The unit is designed for installation in internal rooms, onto walls or ceilings. The room temperature must lie
above 5 °C.
Narrow duct bends result in increased pressure losses and noise pollution. The ventilation pipes
must never be kinked. Ensure the fixed and tight fastening of the connectors. The unit cover must be freely
accessible for maintenance and installation
work. Please ensure you reference the domestic compliance
guide for proper duct installation.
2.1 Ducting installation
When designing the ductwork, use the shortest possible runs. Supply and extract air rooms must be defined
in advance. Extractor hoods must not be connected to the system. Sufficient overflow openings (door gap,
door grilles) as per building regulations are to be provided to ensure air circulation within the room. Shorten
the duct parallel to the rings. To avoid leaks, the pipe must not be cut at an angle. The MultiPlexBox is
prepared for the connection of 125 mm pipes on the inlet side. The supply air and extract air ducts in the
rooms are designed with 75mm Airflex Pro round pipe. The outlet side connections are also 125mm for the
125/125 Straight through version. The connectors are provided with dust covers. These must be broken out
for the connection of air pipes.
