Assembly

The unit is designed for installation in internal rooms, to walls or ceilings. The room temperature must lie above +5 °C.
Narrow bends result in increased pressure losses and flow noises. 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.

Air ducting

When designing the ductwork, use the shortest possible runs. Supply and extract air rooms must be defined in advan-
ce. Filters must generally be integrated in extract air valves. Extractor hoods must not be connected to the system.
Sufficient overflow openings (door gap, door grilles) are to be provided to ensure air circulation within the room.
Existing fire protection regulations must be observed .
