To install the BLAUBERG TwinBox EC 150, follow these steps:
1. Before mounting, ensure that the casing does not contain any foreign objects. Also, make sure there is convenient access for future maintenance and repair.
2. The unit can only be installed in a horizontal position, taking into account the direction of airflow indicated by an arrow on the casing.
3. Use anchor threaded rods with nuts to fix the fan unit to the ceiling. Fasteners for fan mounting are not included in the delivery set and should be ordered separately. Choose fasteners based on the material of the mounting surface and the weight of the fan unit.
4. Connect the straight air duct section to the spigots on both sides of the unit during installation to minimize turbulence-induced air pressure losses. The minimum straight air duct length should be equal to 1 air duct diameter on the intake side and 3 air duct diameters on the outlet side.
5. If the air ducts are too short or not connected, protect the unit parts from the ingress of foreign objects. You can cover the spigots with a protecting grille or other device with a mesh width not exceeding 12.5 mm.
Please refer to the user manual for detailed instructions, including illustrations and diagrams, for the installation process.
