Connect ventilation ducts

– Ventilation duct requirements
When planning and designing the ductwork, use the shortest possible runs. Airtight connections and changeovers
must be ensured. Use smooth ducts to avoid dirt deposits, high pressure loss and loud noises. The duct diameter
DN 160 mm must be provided for the main lines (intake air, exhaust air, supply air, extract air). The diameter can be
reduced accordingly for branch lines. The supply air must be led to living and bedrooms and the extracted air must be
led from utility rooms.
In order to prevent condensation in the intake and exhaust air ducts and any preheater elements or air filter boxes,
these must be suitably insulated. If supply and extract air ducts run through heated rooms, these must also be insulated
to prevent heat losses. The minimum insulation thicknesses according to DIN EN 1946-6, 05/2009 must be observed.
In order to adjust the system, supply and extract air openings must be provided with adjustable valves (accessories). If
contaminated extract air is extracted, a filter (accessories) must be connected upstream.
For hygiene reasons and due to the fire risk, extractor hoods must not be connected to the duct system. In order to
ensure the air circulation within the living space, sufficient overflow openings (door gaps, door ventilation grilles) must
be provided.
Any existing fire protection regulations must be observed .
– Connect ventilation ducts
The units are equipped with four spigots (Ø 160 mm) for connection to the duct system. The ventilation ducts must be
connected firmly and tightly to the spigots. Duct connectors RVBD 160 K (accessories) must be used in this respect.
